The tcon reference is put, which puts the session reference too, but neither pointer is zeroed out. The mount gets retried (goto try_mount_again) with new mount info. Session setup fails fails and rc ends up being non-zero. The code then falls through to the end and tries to put the previously freed tcon pointer again. Oops at: cifs_put_smb_ses+0x14/0xd0 Fix this by moving the initialization of the rc variable and the tcon, pSesInfo and srvTcp pointers below the try_mount_again label.

The thing is: we shouldn't subtract hose->first_busno because PCI core sets PCI primary, secondary and subordinate bus numbers, and PCIe controller actually takes the registers into account. So we should use just bus->number. Also, according to MPC8315 reference manual, primary bus number should always remain 0. We have PPC_INDIRECT_TYPE_SURPRESS_PRIMARY_BUS quirk in indirect_pci.c, but since 83xx is somewhat special, it doesn't use indirect_pci.c routines, so we have to implement the quirk specifically for 83xx PCIe controllers.

It breaks high-order pages previously allocated for non-dio transfer. This patches adds reserved_page_order to st_buffer structure to save page order for non-dio transfer. http://bugzilla.kernel.org/show_bug.cgi?id=14563 When enlarge_buffer() allocates 524288 from 0, st uses six-order page allocation. So mdata->page_order is 6 and frp_seg is 2. After that, if st uses dio, sgl_map_user_pages() sets mdata->page_order to 0 for st_do_scsi(). After that, when we call normalize_buffer(), it frees only free frp_seg * PAGE_SIZE (2 * 4096) though we should free frp_seg * PAGE_SIZE << 6 (2 * 4096 << 6). So we see buffer_size is set to 516096 (524288 - 8192).

If no I/O port resource is assigned to devices, those devices do not work. [1] Some machines support 64KB I/O port space per PCI segment. [2] Some P2P bridges support optional 1KB aligned I/O base. Therefore, I made a patch for MegaRAID SAS driver to make PCI legacy I/O port free. I have also tested the patch and it had no problem. The way to make PCI legacy I/O port free is the same as Fusion-MPT driver's and it has been merged into 2.6.30.4. This has already been fixed in e1000 and lpfc. As a result of the above, the driver can handle its device even when there are a huge number of PCI devices being used on the system and no I/O port region assigned to the device.

One of these things is the possibility for users to call osd_end_request, in any condition at any state. This opens up some problems with calling blk_put_request when out-side of the completion callback but calling __blk_put_request when detecting a from-completion state. The current hack was working just fine until exofs decided to operate on all devices in parallel and wait for the sum of the requests, before deallocating all osd-requests at once. There are two new possible cases 1. All request in a group are deallocated as part of the last request's async-done, request_queue is locked. 2. All request in a group where executed asynchronously, but de-allocation was delayed to after the async-done, in the context of another thread. Async execution but request_queue is not locked. The solution I chose was to separate the deallocation of the osd_request which has the information users need, from the deallocation of the internal(2) requests which impose the locking problem. The internal block-requests are freed unconditionally inside the async-done-callback, when we know the queue is always locked. If at osd_end_request time we still have a bock-request, then we know it did not come from within an async-done-callback and we can call the regular blk_put_request. The internal requests were used for carrying error information after execution. This information is now copied to osd_request members for later analysis by user code. The external API and behaviour was unchanged, except now it really supports what was previously advertised.

These changes introduced a regression on ipr EEH recovery. The ipr device driver saves the PCI state only during the device probe and restores it on ipr_reset_restore_cfg_space() during IOA resets. This behavior is causing the EEH recovery to fail after the second error detected, since the registers are not being restored. One possible solution would be saving the registers after restoring them. The problem with this approach is that while recovering from an EEH error if pci_save_state() results in an EEH error, the adapter/slot will be reset, and end up back in ipr_reset_restore_cfg_space(), but it won't have a valid saved state to restore, so pci_restore_state() will fail. The following patch introduces a workaround for this problem, hacking around the PCI API by setting pdev->state_saved = true before we do the restore.

This patch fix for sata IO circular lock dependency. When we call task_done for SATA IO, we have got pm8001_ha->lock ,and in sas_ata_task_done, it will get (dev->sata_dev.ap->lock. then cause circular lock dependency .So we should drop pm8001_ha->lock when we call task_done for SATA task.

The comment above the function says: * - the caller must hold the RCU read lock The calling code in sys_setpriority does read_lock(&tasklist_lock) but not rcu_read_lock(). This works only when CONFIG_TREE_PREEMPT_RCU=n. With CONFIG_TREE_PREEMPT_RCU=y the rcu_callbacks can run in the tick interrupt when they see no read side critical section. There is another instance of __task_cred() in sys_setpriority() itself which is equally unprotected. Wrap the whole code section into a rcu read side critical section to fix this quick and dirty. Will be revisited in course of the read_lock(&tasklist_lock) -> rcu crusade. Oleg noted further: This also fixes another bug here. find_task_by_vpid() is not safe without rcu_read_lock(). I do not mean it is not safe to use the result, just find_pid_ns() by itself is not safe. Usually tasklist gives enough protection, but if copy_process() fails it calls free_pid() lockless and does call_rcu(delayed_put_pid(). This means, without rcu lock find_pid_ns() can't scan the hash table safely. Signed-off-by: Thomas Gleixner LKML-Reference: <20091210004703.029784964@linutronix.de> Acked-by: Paul E.

This makes fsl_deep_sleep() unusable in drivers' resume() callback. Sure, drivers can store fsl_deep_sleep() value on suspend and use the stored value on resume. But a better solution is to postpone clearing the deep_sleeping variable, i.e. move it into finish() callback.

If a CPU registers more than one per cpu clock event device, then only the active clock event device is removed on CPU_DEAD. The unused devices are kept in the clock events device list. On CPU up the clock event devices are registered again, which means that we list_add an already enqueued list_head. That results in list corruption. Resolve this by removing all devices which are associated to the dead CPU on CPU_DEAD.

This patch gives the arch/$ARCH/include/asm directory priority over include/asm. When we add asm-offsets.h to arch/$ARCH/include/asm/ this patch makes sure we pick up the arch specific version and not the one we have in include/asm. The situation with an asm-offsets.h file located in both include/asm _and_ arch/$ARCH/include/asm will happen when we move more files over to include/generated. This happens because in some cases it is not practical to rename all users so we simply add a file in arch/$ARCH/include/asm that includes the generated version. This is the solution we use for asm-offsets.h as an example.

Without such privileges, deb-pkg errors out because chown fails. The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a command to run other commands with possibly fake elevated privileges. Since this is not needed for the tar-pkg and rpm-pkg targets, it is only used by deb-pkg. If it is not defined, the behavior is as before, and the user will have to rerun make as root. In other words, as a shortcut, instead of running 'make oldconfig && make && fakeroot -u make deb-pkg', one can use the single command 'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

Unless already running as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a good default. With this patch applied, you can run "make oldconfig deb-pkg" as an ordinary user to build a binary package for an updated kernel tree and it should just work. fakeroot is too zealous by default in treating files as owned by root. Its wrapped stat() sets st_uid and st_gid to 0 for all files, which causes Git to go on a wild goose chase if CONFIG_LOCALVERSION_AUTO is set, checking if any file's content has changed along with its stat information. Avoid this by telling fakeroot to use the actual owner and group for preexisting files, by passing it the -u option.

The running vmcore showed the following: a) Port was in RESTART state b) rdata->event was STOP c) no work gets scheduled for the remote work to fc_rport_work After this point, shut/no-shut of the remote port did not cause the port to get re-discovered. The port would move betwen DELETE and RESTART states, but the event would always be STOP, no work would get scheduled to fc_rport_work and the port would not get added to scsi_transport. The problem is that rdata->event is not set to NONE after a port is restarted. After this point, no more work gets scheduled for the remote port since new work is scheduled only if rdata->event is non-NONE. So, the event and state keep changing, but fc_rport_work does not get scheduled to actually handle the event. Here's a transition of states that explains the above observation: ) Port is first in READY State, event is NONE 2) RSCN on shut, port goes to DELETED, event is stop 3) Before fc_rport_work runs, RSCN on no-shut, port goes to RESTART, event is still STOP 4) fc_rport_work gets scheduled, removes the port from transport, sees state as RESTART, begins the PLOGI state machine, event remains as STOP (event NOT changed to NONE, this is the bug) 5) Plogi state machine completes, port state goes to READY, event goes to READY, but no work is scheduled since event was STOP (non-NONE) before. Fc_rport_work is not scheduled, port remains in READY state, but is not added to transport. Things are broken at this point. Libfc rport is ready, but no transport rport created. 6) now a shut causes port state to change to DELETE, event to change to STOP, no work gets scheduled 7) no-shut causes port state to change to RESTART, event remains at STOP, no work gets scheduled (6) and (7) now get repeated everytime we do shut/no-shut. No way to get out of this state. Fcc reset does not help too. Only way to get out is to load/unload module. Fix is to set rdata->event to NONE while processing the STOP/LOGO/FAILED events, inside the discovery and rport locks.

Adds sysfs module param enable and disable for this and also updates existing other module param description to be consistent and more accurate since older description had double "fcoe" word with less meaningful netdev reference to user space. Adds code to ignore redundant fc_lport_enter_reset handling for a already disabled fcoe interface by checking LPORT_ST_DISABLED or LPORT_ST_LOGO states, this also prevents lport state transition on link flap on a disabled interface.

Also the reiserfs lock can be acquired recursively, but since its implementation depends on a mutex, it's hard and not necessary worth it to teach that to lockdep. The lock is useless at mount time anyway, at least until we replay the journal. But let's remove it from this path later as this needs more thinking and is a sensible change.

But this trick actually fails if we have acquired the reiserfs lock recursively, as we try to unlock it to acquire the new mutex without inverted dependency, but we eventually only decrease its depth. This happens in the case of a nested inode creation/deletion. Say we have no space left on the device, we create an inode and tak the lock but fail to create its entry, then we release the inode using iput(), which calls reiserfs_delete_inode() that takes the reiserfs lock recursively.

We gain no advantage in the cache controller stalling the bus until completion. What we should be doing is using the 'wait' time productively by calculating the address of the next operation, and only then waiting for the previous operation to complete. This means that cache operations can occur in parallel with the CPU calculating the next address.

The background is that I was trying to resolve a sparc64 perf issue when I discovered this problem. On sparc64 I implement pseudo NMIs by simply running the kernel at IRQ level 14 when local_irq_disable() is called, this allows performance counter events to still come in at IRQ level 15. This doesn't work if any code in an NMI handler does local_irq_save() or local_irq_disable() since the "disable" will kick us back to cpu IRQ level 14 thus letting NMIs back in and we recurse. The only path which that does that in the perf event IRQ handling path is the code supporting frequency based events. It uses cpu_clock(). cpu_clock() simply invokes sched_clock() with IRQs disabled. And that's a fundamental bug all on it's own, particularly for the HAVE_UNSTABLE_SCHED_CLOCK case. NMIs can thus get into the sched_clock() code interrupting the local IRQ disable code sections of it. Furthermore, for the not-HAVE_UNSTABLE_SCHED_CLOCK case, the IRQ disabling done by cpu_clock() is just pure overhead and completely unnecessary. So the core problem is that sched_clock() is not NMI safe, but we are invoking it from NMI contexts in the perf events code (via cpu_clock()). A less important issue is the overhead of IRQ disabling when it isn't necessary in cpu_clock(). CONFIG_HAVE_UNSTABLE_SCHED_CLOCK architectures are not affected by this patch. Signed-off-by: David S.

There's notes in nv40_grctx.c explaining most of the things we don't implement. If we discover if/why any of it is required further down the track, we'll handle it then. The PGRAPH state generated for each chipset should match what NVIDIA do almost exactly (there's a couple of exceptions). If someone has a lot of time on their hands, they could figure out the mapping of object/method to PGRAPH register and demagic the initial state a little, it's not terribly important however. At time of commit, confirmed to be working at least well enough for accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46, NV49, NV4A, NV4B and NV4E. A module option has been added to force the use of external firmware blobs if it becomes required.

We'll implement additional handling if/when we + * discover it's necessary. + * + * - On context save, NVIDIA set 0x400314 bit 0 to 1 if the "3D state" + * flag is set, this gets saved into the context. + * - On context save, the context program for all cards load nsource + * into a flag register and check for ILLEGAL_MTHD. If it's set, + * opcode 0x60000d is called before resuming normal operation. + * - Some context programs check more conditions than the above. NV44 + * checks: ((nsource & 0x0857) || (0x400718 & 0x0100) || (intr & 0x0001)) + * and calls 0x60000d before resuming normal operation. + * - At the very beginning of NVIDIA's context programs, flag 9 is checked + * and if true 0x800001 is called with count=0, pos=0, the flag is cleared + * and then the ctxprog is aborted. It looks like a complicated NOP, + * its purpose is unknown. + * - In the section of code that loads the per-vs state, NVIDIA check + * flag 10. If it's set, they only transfer the small 0x300 byte block + * of state + the state for a single vs as opposed to the state for + * all vs units. It doesn't seem likely that it'll occur in normal + * operation, especially seeing as it appears NVIDIA may have screwed + * up the ctxprogs for some cards and have an invalid instruction + * rather than a cp_lsr(ctx, dwords_for_1_vs_unit) instruction. + * - There's a number of places where context offset 0 (where we place + * the PRAMIN offset of the context) is loaded into either 0x408000, + * 0x408004 or 0x408008. Not sure what's up there either. + * - The ctxprogs for some cards save 0x400a00 again during the cleanup + * path for auto-loadctx. + */ + +#define CP_FLAG_CLEAR 0 +#define CP_FLAG_SET 1 +#define CP_FLAG_SWAP_DIRECTION ((0 * 32) + 0) +#define CP_FLAG_SWAP_DIRECTION_LOAD 0 +#define CP_FLAG_SWAP_DIRECTION_SAVE 1 +#define CP_FLAG_USER_SAVE ((0 * 32) + 5) +#define CP_FLAG_USER_SAVE_NOT_PENDING 0 +#define CP_FLAG_USER_SAVE_PENDING 1 +#define CP_FLAG_USER_LOAD ((0 * 32) + 6) +#define CP_FLAG_USER_LOAD_NOT_PENDING 0 +#define CP_FLAG_USER_LOAD_PENDING 1 +#define CP_FLAG_STATUS ((3 * 32) + 0) +#define CP_FLAG_STATUS_IDLE 0 +#define CP_FLAG_STATUS_BUSY 1 +#define CP_FLAG_AUTO_SAVE ((3 * 32) + 4) +#define CP_FLAG_AUTO_SAVE_NOT_PENDING 0 +#define CP_FLAG_AUTO_SAVE_PENDING 1 +#define CP_FLAG_AUTO_LOAD ((3 * 32) + 5) +#define CP_FLAG_AUTO_LOAD_NOT_PENDING 0 +#define CP_FLAG_AUTO_LOAD_PENDING 1 +#define CP_FLAG_UNK54 ((3 * 32) + 6) +#define CP_FLAG_UNK54_CLEAR 0 +#define CP_FLAG_UNK54_SET 1 +#define CP_FLAG_ALWAYS ((3 * 32) + 8) +#define CP_FLAG_ALWAYS_FALSE 0 +#define CP_FLAG_ALWAYS_TRUE 1 +#define CP_FLAG_UNK57 ((3 * 32) + 9) +#define CP_FLAG_UNK57_CLEAR 0 +#define CP_FLAG_UNK57_SET 1 + +#define CP_CTX 0x00100000 +#define CP_CTX_COUNT 0x000fc000 +#define CP_CTX_COUNT_SHIFT 14 +#define CP_CTX_REG 0x00003fff +#define CP_LOAD_SR 0x00200000 +#define CP_LOAD_SR_VALUE 0x000fffff +#define CP_BRA 0x00400000 +#define CP_BRA_IP 0x0000ff00 +#define CP_BRA_IP_SHIFT 8 +#define CP_BRA_IF_CLEAR 0x00000080 +#define CP_BRA_FLAG 0x0000007f +#define CP_WAIT 0x00500000 +#define CP_WAIT_SET 0x00000080 +#define CP_WAIT_FLAG 0x0000007f +#define CP_SET 0x00700000 +#define CP_SET_1 0x00000080 +#define CP_SET_FLAG 0x0000007f +#define CP_NEXT_TO_SWAP 0x00600007 +#define CP_NEXT_TO_CURRENT 0x00600009 +#define CP_SET_CONTEXT_POINTER 0x0060000a +#define CP_END 0x0060000e +#define CP_LOAD_MAGIC_UNK01 0x00800001 /* unknown */ +#define CP_LOAD_MAGIC_NV44TCL 0x00800029 /* per-vs state (0x4497) */ +#define CP_LOAD_MAGIC_NV40TCL 0x00800041 /* per-vs state (0x4097) */ + +#include "drmP.h" +#include "nouveau_drv.h" +#include "nouveau_grctx.h" + +/* TODO: + * - get vs count from 0x1540 + * - document unimplemented bits compared to nvidia + * - nsource handling + * - R0 & 0x0200 handling + * - single-vs handling + * - 400314 bit 0 + */ + +static int +nv40_graph_4097(struct drm_device *dev) +{ + struct drm_nouveau_private *dev_priv = dev->dev_private;

I don't have any need for brightness control, and its code is *completely* separate from the on/off controls implemented here. If anyone else wants it, I'd be happy to look into adding it, but I don't care enough for now. Except for the probe routines, I rewrote most of it. I also Note that I don't have any hardware documentation except for the original driver. Thanks go to Arjan for his help in getting the original source for this released and for chasing down some licensing issues.

The simple approach is to substract cfs_rq->min_vruntime from se->vruntime on dequeue, and add cfs_rq->min_vruntime on enqueue. However, this has the downside of breaking FAIR_SLEEPERS since we loose the old vruntime as we only maintain the relative position. To solve this, we observe that we only migrate runnable tasks, we do this using deactivate_task(.sleep=0) and activate_task(.wakeup=0), therefore we can restrain the min_vruntime invariance to that state. The only other case is wakeup balancing, since we want to maintain the old vruntime we cannot make it relative on dequeue, but since we don't migrate inactive tasks, we can do so right before we activate it again. This is where we need the new pre-wakeup hook, we need to call this while still holding the old rq->lock. We could fold it into ->select_task_rq(), but since that has multiple callsites and would obfuscate the locking requirements, that seems like a fudge. This leaves the fork() case, simply make sure that ->task_fork() leaves the ->vruntime in a relative state. This covers all cases where set_task_cpu() gets called, and ensures it sees a relative vruntime.

At the moment, the smsc47m1 driver requests the whole I/O port range. This could easily result in resource conflicts with either ACPI or other drivers. Request only the I/O ports we really use, to prevent such conflicts.

And I also reproduce this issue on another laptop. After some tests and debug, it seems that it is related with that the LVDS status is not updated in time in course of suspend/resume. Now the LID state is used to check whether the LVDS is connected or disconnected. And when the LID is closed, it means that the LVDS is disconnected. When it is reopened, it means that the LVDS is connected. At the same time on some distributions the LID event is also used to put the system into suspend state. When the LID is closed, the system will enter the suspend state. When the LID is reopened, the system will be resumed. In such case when the LID is closed, user-space script will receive the LID notification event and detect the LVDS as disconnected. Then the system will enter the suspended state. When the LID is reopened, the system will be resumed. As the LVDS status is not updated in course of resume, it will cause that the LVDS connector is marked as unused and disabled. After the resume is finished,user-space script will try to configure the display mode for LVDS. But unfortunately as the LVDS status is not updated in time and it is still marked as disconnected, the LVDS and its corresponding CRTC will be disabled again in the function of drm_helper_disable_unused_functions after changing mode for LVDS.

Wysocki" Date: Sun, 29 Nov 2009 16:35:54 +0100 Subject: PCI/PM: Propagate wake-up enable for PCIe devices too Having read the PM part of the PCIe 2.0 specification more carefully I think that it was a mistake to restrict the wake-up enable propagation to non-PCIe devices, because if we do not request control of the root ports' PME registers via OSC, PCIe PME is supposed to be handled by the platform, just like the non-PCIe PME. Even if we do that, the wake-up propagation is done to allow the devices to wake up the system from sleep states which involves the platform anyway, so it won't hurt. Signed-off-by: Rafael J.

This patch ensures the pci_cache_line_size = pci_dfl_cache_line_size setting in the above scenario. This happens in case of a kvm-88 guest (where, consequently, the rtl8139 NIC failed to initialize).

As we don't have volatile keyword for native_cpuid(), gcc 4.1.2 optimizes away the second cpuid and the kernel continues to use the cpuid information obtained before xsetbv(), ultimately leading to kernel crash on processors supporting more state than the legacy FP/SSE.

The Octeon SOC has two types of Ethernet ports, each type with its own driver. However, the PHYs for all the ports are controlled by a common MDIO bus. Because the mdio driver is not associated with a particular driver, but is instead a system level resource, we create s stand-alone driver for it. As for the driver, we put the register definitions in arch/mips/include/asm/octeon where most of the other Octeon register definitions live. This is a platform driver with the platform device for "mdio-octeon" being registered in the platform startup code. Signed-off-by: David Daney Acked-by: David S.

The Octeon MGMT Ethernet ports are present in some members of the Octeon SOC family (cn52XX and cn56XX have them). The mdio bus connected to the MGMT PHYs is shared with the main octeon-ethernet driver, we force it to be loaded first by calling octeon_mdiobus_force_mod_depencency. The platform devices for the MGMT Ethernet ports are added in arch/mips/cavium-octeon/octeon-platform.c, and the register definitions for the ports live in arch/mips/include/asm/octeon/ along with their ilk. Although it currently is the only driver in drivers/net/octeon, the directory was created looking forward to the day that octeon-ethernet will move there from its current home in drivers/staging.

Processors that support the mips64r2 ISA can in four instructions convert a shifted PGD pointer stored in the upper bits of c0_context into a usable pointer. By doing this we save a memory load and associated potential cache miss in the TLB exception handlers. Since the upper bits of c0_context were holding the CPU number, we move this to the upper bits of c0_xcontext which doesn't have enough bits to hold the PGD pointer, but has plenty for the CPU number.

The built-in Loongson 2E/2F northbridge in is bonito64-compatible but not identical with it. To avoid influencing the original bonito64 support and make the loongson support more maintainable, it's better to separate the Bonito64 code from the Loongson code.

On SMP systems, the collection of statistics can cause cache line bouncing in the lines associated with the counters. Also there are races incrementing the counters on multiple CPUs. To fix both problems, we collect the statistics in per-CPU variables, and add them up in the debugfs read operation. As a test I ran the LTP float_bessel test on a 12 CPU Octeon system. Without CONFIG_DEBUG_FS : 2602 seconds. With CONFIG_DEBUG_FS: 2640 seconds. With non-cpu-local atomic statistics: 14569 seconds.

The PCI-X controller has a programming interface similiar to the the FPGA northbridge used on Loongson 2E. The main differences between Loongson 2E and Loongson 2F include: 1. Loongson 2F has an extra address window configuration module, which is used to map CPU address space to DDR or PCI address space, or map the PCI-DMA address space to DDR or LIO address space. 2. Loongson 2F supports 8 levels of software configurable CPu frequency which can be configured in the LOONGSON_CHIPCFG0 register. The coming cpufreq and standby support are based on this feature. Loongson.h abstracts the modules and corresponding methods are abstracted. Add other Loongson-2F-specific source code including gcc 4.4 support, PCI memory space, PCI IO space, DMA address.

2009 13:39:12 +0800 Subject: MIPS: Loongson 2F: Cleanup the #if clauses This patch adds two new kernel options: CPU_SUPPORTS_CPUFREQ and CPU_SUPPORTS_ADDRWINCFG to describe the new features of Loongons 2F and replaces the several ugly #if clauses by them. These two options will be utilized by the future loongson revisions and related drivers such as the coming Loongson 2F CPUFreq driver.

These interrupts are board-specific, Yeeloong2F use the keyboard interrupt and SCI interrupt, but LingLoong and Fuloong2F use the interrupts connected to the processors directly. and BTW: some old LingLoong and FuLoong2F have no such interrupts connected, so, there is no way to wake them up from suspend mode. and therefore, please do not enable the kernel support for them. The board-specific support will be added in the coming patches.

When enabling it in user-space, it will jump to a real tracing function(ftrace_caller), and do the real job for us. Differ from the static function tracer, dynamic function tracer provides two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the tracing of some indicated kernel functions(set_ftrace_filter). In the -v4 version, the implementation of this support is basically the same as X86 version does: _mcount is implemented as an empty function and ftrace_caller is implemented as a real tracing function respectively. But in this version, to support module tracing with the help of -mlong-calls in arch/mips/Makefile: MODFLAGS += -mlong-calls. The stuff becomes a little more complex. We need to cope with two different type of calling to _mcount. For the kernel part, the calling to _mcount(result of "objdump -hdr vmlinux"). is like this: 108: 03e0082d move at,ra 10c: 0c000000 jal 0 10c: R_MIPS_26 _mcount 10c: R_MIPS_NONE *ABS* 10c: R_MIPS_NONE *ABS* 110: 00020021 nop For the module with -mlong-calls, it looks like this: c: 3c030000 lui v1,0x0 c: R_MIPS_HI16 _mcount c: R_MIPS_NONE *ABS* c: R_MIPS_NONE *ABS* 10: 64630000 daddiu v1,v1,0 10: R_MIPS_LO16 _mcount 10: R_MIPS_NONE *ABS* 10: R_MIPS_NONE *ABS* 14: 03e0082d move at,ra 18: 0060f809 jalr v1 In the kernel version, there is only one "_mcount" string for every kernel function, so, we just need to match this one in mcount_regex of scripts/recordmcount.pl, but in the module version, we need to choose one of the two to match. Herein, I choose the first one with "R_MIPS_HI16 _mcount". and In the kernel verion, without module tracing support, we just need to replace "jal _mcount" by "jal ftrace_caller" to do real tracing, and filter the tracing of some kernel functions via replacing it by a nop instruction. but as we have described before, the instruction "jal ftrace_caller" only left 32bit length for the address of ftrace_caller, it will fail when calling from the module space. so, herein, we must replace something else. the basic idea is loading the address of ftrace_caller to v1 via changing these two instructions: lui v1,0x0 addiu v1,v1,0 If we want to enable the tracing, we need to replace the above instructions to: lui v1, HI_16BIT_ftrace_caller addiu v1, v1, LOW_16BIT_ftrace_caller If we want to stop the tracing of the indicated kernel functions, we just need to replace the "jalr v1" to a nop instruction. but we need to replace two instructions and encode the above two instructions oursevles. Is there a simpler solution? Yes! Here it is, in this version, we put _mcount and ftrace_caller together, which means the address of _mcount and ftrace_caller is the same: _mcount: ftrace_caller: j ftrace_stub nop ...(do real tracing here)... ftrace_stub: jr ra move ra, at By default, the kernel functions call _mcount, and then jump to ftrace_stub and return. and when we want to do real tracing, we just need to remove that "j ftrace_stub", and it will run through the two "nop" instructions and then do the real tracing job. what about filtering job? we just need to do this: lui v1, hi_16bit_of_mcount <--> b 1f (0x10000004) addiu v1, v1, low_16bit_of_mcount move at, ra jalr v1 nop 1f: (rec->ip + 12) In linux-mips64, there will be some local symbols, whose name are prefixed by $L, which need to be filtered. thanks goes to Steven for writing the mips64-specific function_regex. In a conclusion, with RISC, things becomes easier with such a "stupid" trick, RISC is something like K.I.S.S, and also, there are lots of "simple" tricks in the whole ftrace support, thanks goes to Steven and the other folks for providing such a wonderful tracing framework!

'Cause we can not prove there is only a match in the stack space, so, we search the text instead. as we can see, if the first instruction above "move at, ra" is not a store instruction, there should be a leaf function, so we hijack the at register directly via putting &return_to_handler into it, otherwise, we search the "s{d,w} ra, offset(sp)" instruction to get the stack offset, and then the stack address. we use the above copy_process() as an example, we at last find "ffbf00a8", 0xa8 is the stack offset, we plus it with s8(fp), that is the stack address, we hijack the content via writing the &return_to_handler in.

Benefit from this new feature, function graph tracer on MIPS will be easier and safer to hijack the return address of the kernel function, which will save some overhead and make the whole thing more reliable. In this patch, at first, try to enable the option -mmcount-ra-address in arch/mips/Makefile with cc-option, if gcc support it, it will be enabled, otherwise, no side effect. and then, we need to support this new option of gcc 4.5 and also support the old gcc versions. with _mcount in the old gcc versions, it's not easy to get the location of return address(tracing: add function graph tracer support for MIPS), so, we do it in a C function: ftrace_get_parent_addr(ftrace.c), but with -mmcount-ra-address, only several instructions need to get what we want, so, I put into asm(mcount.S). and also, as the $12(t0) is used by -mmcount-ra-address for transferring the localtion of return address to _mcount, we need to save it into the stack and restore it when enabled dynamic function tracer, 'Cause we have called "ftrace_call" before "ftrace_graph_caller", which may destroy $12(t0). (Thanks to David for providing that -mcount-ra-address and giving the idea of KBUILD_MCOUNT_RA_ADDRESS, both of them have made the whole thing more beautiful!)

Therefore, using firmware remains the only reliable method to transfer the command-line parameters, which is not always desirable or convenient, and the CONFIG_CMDLINE option is thereby effectively rendered useless. This patch fixes the problem described above and introduces a more flexible scheme of handling the kernel command line, in a manner identical to what is currently used for x86. The default behavior, i.e. when CONFIG_CMDLINE_BOOL is not defined, retains the existing semantics, and firmware command-line arguments override the hardcoded ones.

There's in fact a commented out call to pcibios_fixup_bus() in there, it's commented because ... it doesn't work. I could make pcibios_fixup_bus() do the right thing on powerpc easily but I felt it cleaner instead to provide a specific hook pci_fixup_cardbus for which a weak empty implementation is provided by the PCI core. This fixes cardbus on powerbooks and probably all other PowerPC platforms which was broken completely for ever on some platforms and since 2.6.31 on others such as PowerBooks when we made the DMA ops mandatory (since those are setup by the fixups).

Currently, might_sleep() doesn't notice sleepable operations under rcu_read_lock() sections if we are running under preemptable rcu because preempt_count() is left untouched after rcu_read_lock() in this case. But we want developers who test their changes under such config to notice the "sleeping while atomic" issues. So we add rcu_read_lock_nesting to prempt_count() in might_sleep() checks.

This is intended to allow rapid voltage switching for uses like cpufreq, replacing the I2C or SPI write used to configure the voltage of the regulator with a much faster GPIO status change. This is implemented by keeping the DVS voltage configured as the maximum voltage permitted for the regulator. If a request is made for the maximum voltage then the GPIO is used to switch to the DVS voltage, otherwise the normal ON voltage is updated and used. This follows the idiom used by most cpufreq drivers, which drop the minimum voltage as the core frequency is dropped but use a constant maximum - raising the voltage should normally be fast, but lowering it may be slower. Configuration of the DVS MFP on the device should be done externally, for example via OTP. Support is present in the hardware for monitoring the status of the transition using a second GPIO. This is not currently implemented but platform data is provided for it - the driver currently assumes that the device will be configured to transition immediately - but platform data is provided to reduce merge issues once it is.

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - define needed registers and bits in the driver - properly namespace functions and structs - fix locking as required by patch "mfd/mc13783: near complete rewrite" - use platform_data as provided by "mfd/mc13783: near complete rewrite" instead of accessing struct mc13783 - struct mc13783_regulator_priv.desc is (and was) unused and so can go away - use cpp magic to initialize mc13783_regulators - bring MODULE_LICENSE in sync with actual copyright - minor style fixes This allows not including mc13783-private.h which I

This allows the driver to get DMA-like performance where there are either no free DMA channels or when doing transfers that required both TX and RX data paths. Since this patch requires the addition of an assembly file to hold the FIQ code, we rename the module (instead of adding a rename of the .c file to this patch). We expect most users are loading this via udev and thus there should be no change to the userland configuration.

which is constant; i.e. we just send the last BUFFER_SIZE data over again until we've reached the right number of bytes. This patch gets around this by using the /requested/ length when calculating addresses. Note there's no way len != *plen when we calculate the rx buffer address but conceptually we should be using *plen and I don't want someone to come through later, see the calculations for rx and tx are different and "clean up" back to what we had.

We implement a workaround to support multi-cs by _not_ configuring the mux'ed CS pin for each SPI controller. The CS mechanism is assumed to be fully machine specific - the driver doesn't even assume some GPIO pin is used to control the CS. The driver selects between DMA and POLLING mode depending upon the xfer size - DMA mode for xfers bigger than FIFO size, POLLING mode otherwise. The driver has been designed to be capable of running SoCs since s3c64xx and till date, for that reason some of the register fields have been passed via, SoC specific, platform data.

The latter problem is usually invisible, because maximum transfer size per chunk is 16M, but if you artificially set this limit lower, the driver fails. Since cookies are also used in chunk management, both these problems are fixed in one patch. As side effects a possible memory leak, when descriptors are prepared, but not submitted, and multiple races have also been fixed.

The driver can perform a 3 source calculation with a single descriptor, but needs an extended descriptor to process up to 8 sources in one operation. However, in the p-disabled case only one extra source is needed. When continuing a p-disabled operation there are occasions (i.e. 0 < src_cnt % 8 < 3) where the tail operation does not need an extended descriptor. Properly account for this fact otherwise invalid 'dmacount' values will be written to hardware usually causing the channel to halt with 'invalid descriptor' errors.

But, there seems to be few systems that will end up with TSC warp across sockets, depending on how the cpus come out of reset. Skipping TSC sync test on such systems may result in time inconsistency later. So, reenable TSC sync test even on constant and non-stop TSC systems. Set, sched_clock_stable to 1 by default and reset it in mark_tsc_unstable, if TSC sync fails. This change still gives perf benefit mentioned in 83ce4009 for systems where TSC is reliable.

Currently we add sub-threads to ->real_parent->children list. This buys nothing but slows down do_wait(). With this patch ->children contains only main threads (group leaders). The only complication is that forget_original_parent() should iterate over sub-threads by hand, and de_thread() needs another list_replace() when it changes ->group_leader. Henceforth do_wait_thread() can never see task_detached() && !EXIT_DEAD tasks, we can remove this check (and we can unify do_wait_thread() and ptrace_do_wait()). This change can confuse the optimistic search in mm_update_next_owner(), but this is fixable and minor. Perhaps badness() and oom_kill_process() should be updated, but they should be fixed in any case.

For I2C devices there is I2C_CLIENT_WAKE flag exists that we can pass via board info, and if set, I2C core will initialize wakeup capability. For SPI devices there is no such flag at all. I believe that it's not platform code responsibility to allow or disallow wakeups, instead, drivers themselves should set the capability if a device can trigger wakeups. That's what drivers/base/power/sysfs.c says: * It is the responsibility of device drivers to enable (or disable) * wakeup signaling as part of changing device power states, respecting * the policy choices provided through the driver model. I2C and SPI RTC devices send wakeup events via interrupt lines, so we should set the wakeup capability if IRQ is routed. Ideally we should also check irq for wakeup capability before setting device's capability, i.e. if (can_irq_wake(irq)) device_set_wakeup_capable(&client->dev, 1); But there is no can_irq_wake() call exist, and it is not that trivial to implement it for all interrupts controllers and complex/cascaded setups. drivers/base/power/sysfs.c also covers these cases: * Devices may not be able to generate wakeup events from all power * states. Also, the events may be ignored in some configurations; * for example, they might need help from other devices that aren't * active So there is no guarantee that wakeup will actually work, and so I think there is no point in being pedantic wrt checking IRQ wakeup capability.

The normal case is, if page N become uptodate at time T(N), then T(N) <= T(N+1) holds. With RAID (and NFS to some degree), there is no strict ordering, the data arrival time depends on runtime status of individual disks, which breaks that formula.

As a result, the suspend/resume timing information is only available for devices whose bus types or device classes use struct dev_pm_ops objects, so the majority of devices is not covered. Fix this by adding basic suspend/resume timing instrumentation for devices whose bus types and device classes still don't use struct dev_pm_ops objects for power management. To reduce code duplication move the timing code to helper functions. Signed-off-by: Rafael J.

Moving the lock into the drm_ioctl function itself makes sure we blame the right subsystem and it gets us one step closer to eliminating the locked version of fops->ioctl. Since drm_ioctl does not require the lock itself, we only need to hold it while calling the specific handler. The 32 bit conversion handlers do not interact with any other code, so they don't need the BKL here either and can just call drm_ioctl. As a bonus, this cleans up all the other users of drm_ioctl which now no longer have to find the inode or call lock_kernel.

Prior to calling the memory hotplug notifier chain the memory in the pageblock is isolated. Currently, if the migrate type is not MIGRATE_MOVABLE the isolation will not proceed, causing the memory removal for that page range to fail. Rather than failing pageblock isolation if the migrateteype is not MIGRATE_MOVABLE, this patch checks if all of the pages in the pageblock, and not on the LRU, are owned by a registered balloon driver (or other entity) using a notifier chain. If all of the non-movable pages are owned by a balloon, they can be freed later through the memory notifier chain and the range can still be isolated in set_migratetype_isolate().

On a long running system this can severely impact the ability to find enough pages to support a hotplug memory remove operation. This patch adds a memory isolation notifier and a memory hotplug notifier. The memory isolation notifier will return the number of pages found in the range specified. This is used to determine if all of the used pages in a pageblock are owned by the balloon (or other entities in the notifier chain). The hotplug notifier will free pages in the range which is to be removed. The priority of this hotplug notifier is low so that it will be called near last, this helps avoids removing loaned pages in operations that fail due to other handlers. CMM activity will be halted when hotplug remove operations are active and resume activity after a delay period to allow the hypervisor time to adjust.

Furthermore I think there a few reasons we should reduce HZ to 100: - Timer interrupt overhead. While this overhead is small, there are applications that are very sensitive to jitter (eg some HPC apps). - Issues with the timer wheel code. When coming out of NO_HZ idle we work our way through the timer code one tick at a time. If we have been idle a long time, this adds up - I sometimes see milliseconds of time spent in that loop. Long term we should fix the timer wheel algorithm, but for now if we reduce HZ then we reduce the amount of work the timer code has to do when coming out of idle.

The -as-iosched anticipatory implementation is based on the notion that a disk -device has only one physical seeking head. A striped RAID controller -actually has a head for each physical device in the logical RAID device. - -However, setting the antic_expire (see tunable parameters below) produces -very similar behavior to the deadline IO scheduler. - -Selecting IO schedulers ------------------------ -Refer to Documentation/block/switching-sched.txt for information on -selecting an io scheduler on a per-device basis. - -Anticipatory IO scheduler Policies ----------------------------------- -The as-iosched implementation implements several layers of policies -to determine when an IO request is dispatched to the disk controller. -Here are the policies outlined, in order of application. - -1. one-way Elevator algorithm. - -The elevator algorithm is similar to that used in deadline scheduler, with -the addition that it allows limited backward movement of the elevator -(i.e. seeks backwards). A seek backwards can occur when choosing between -two IO requests where one is behind the elevator's current position, and -the other is in front of the elevator's position. If the seek distance to -the request in back of the elevator is less than half the seek distance to -the request in front of the elevator, then the request in back can be chosen. -Backward seeks are also limited to a maximum of MAXBACK (1024*1024) sectors. -This favors forward movement of the elevator, while allowing opportunistic -"short" backward seeks. - -2. FIFO expiration times for reads and for writes. - -This is again very similar to the deadline IO scheduler. The expiration -times for requests on these lists is tunable using the parameters read_expire -and write_expire discussed below. When a read or a write expires in this way, -the IO scheduler will interrupt its current elevator sweep or read anticipation -to service the expired request. - -3. Read and write request batching - -A batch is a collection of read requests or a collection of write -requests. The as scheduler alternates dispatching read and write batches -to the driver. In the case a read batch, the scheduler submits read -requests to the driver as long as there are read requests to submit, and -the read batch time limit has not been exceeded (read_batch_expire). -The read batch time limit begins counting down only when there are -competing write requests pending. - -In the case of a write batch, the scheduler submits write requests to -the driver as long as there are write requests available, and the -write batch time limit has not been exceeded (write_batch_expire). -However, the length of write batches will be gradually shortened -when read batches frequently exceed their time limit. - -When changing between batch types, the scheduler waits for all requests -from the previous batch to complete before scheduling requests for the -next batch. - -The read and write fifo expiration times described in policy 2 above -are checked only when in scheduling IO of a batch for the corresponding -(read/write) type. So for example, the read FIFO timeout values are -tested only during read batches. Likewise, the write FIFO timeout -values are tested only during write batches. For this reason, -it is generally not recommended for the read batch time -to be longer than the write expiration time, nor for the write batch -time to exceed the read expiration time (see tunable parameters below). - -When the IO scheduler changes from a read to a write batch, -it begins the elevator from the request that is on the head of the -write expiration FIFO. Likewise, when changing from a write batch to -a read batch, scheduler begins the elevator from the first entry -on the read expiration FIFO. - -4. Read anticipation. - -Read anticipation occurs only when scheduling a read batch. -This implementation of read anticipation allows only one read request -to be dispatched to the disk controller at a time. In -contrast, many write requests may be dispatched to the disk controller -at a time during a write batch. It is this characteristic that can make -the anticipatory scheduler perform anomalously with controllers supporting -TCQ, or with hardware striped RAID devices. Setting the antic_expire -queue parameter (see below) to zero disables this behavior, and the -anticipatory scheduler behaves essentially like the deadline scheduler. - -When read anticipation is enabled (antic_expire is not zero), reads -are dispatched to the disk controller one at a time. -At the end of each read request, the IO scheduler examines its next -candidate read request from its sorted read list. If that next request -is from the same process as the request that just completed, -or if the next request in the queue is "very close" to the -just completed request, it is dispatched immediately. Otherwise, -statistics (average think time, average seek distance) on the process -that submitted the just completed request are examined. If it seems -likely that that process will submit another request soon, and that -request is likely to be near the just completed request, then the IO -scheduler will stop dispatching more read requests for up to (antic_expire) -milliseconds, hoping that process will submit a new request near the one -that just completed. If such a request is made, then it is dispatched -immediately. If the antic_expire wait time expires, then the IO scheduler -will dispatch the next read request from the sorted read queue. - -To decide whether an anticipatory wait is worthwhile, the scheduler -maintains statistics for each process that can be used to compute -mean "think time" (the time between read requests), and mean seek -distance for that process. One observation is that these statistics -are associated with each process, but those statistics are not associated -with a specific IO device. So for example, if a process is doing IO -on several file systems on separate devices, the statistics will be -a combination of IO behavior from all those devices. - - -Tuning the anticipatory IO scheduler ------------------------------------- -When using 'as', the anticipatory IO scheduler there are 5 parameters under -/sys/block/*/queue/iosched/. All are units of milliseconds. - -The parameters are: -* read_expire - Controls how long until a read request becomes "expired". It also controls the - interval between which expired requests are served, so set to 50, a request - might take anywhere < 100ms to be serviced _if_ it is the next on the - expired list. Obviously request expiration strategies won't make the disk - go faster. The result basically equates to the timeslice a single reader - gets in the presence of other IO. 100*((seek time / read_expire) + 1) is - very roughly the % streaming read efficiency your disk should get with - multiple readers. - -* read_batch_expire - Controls how much time a batch of reads is given before pending writes are - served. A higher value is more efficient. This might be set below read_expire - if writes are to be given higher priority than reads, but reads are to be - as efficient as possible when there are no writes. Generally though, it - should be some multiple of read_expire. - -* write_expire, and -* write_batch_expire are equivalent to the above, for writes. - -* antic_expire - Controls the maximum amount of time we can anticipate a good read (one - with a short seek distance from the most recently completed request) before - giving up. Many other factors may cause anticipation to be stopped early, - or some processes will not be "anticipated" at all. Should be a bit higher - for big seek time devices though not a linear correspondence - most - processes have only a few ms thinktime. - -In addition to the tunables above there is a read-only file named est_time -which, when read, will show: - - - The probability of a task exiting without a cooperating task - submitting an anticipated IO. - - - The current mean think time. - - - The seek distance used to determine if an incoming IO is better. - -- cgit v1.2.3 From 4a63b030d75a063b910b2bab014d84837cb33eb7 Mon Sep 17 00:00:00 2001 From: Roel Kluin Date: Fri, 18 Dec 2009 12:38:11 +0100 Subject: drbd: fix test of unsigned in _drbd_fault_random() rsp->count is unsigned so the test does not work.

Which workload to run depends primarily on rb_key offset across three service trees. Which is a combination of mulitiple things including what time queue got queued on the service tree. There is one exception though. That is if we switched the prio class, say we served some RT tasks and again started serving BE class, then with-in BE class we always started with sync-noidle workload irrespective of rb_key offset in service trees. This can provide better latencies for sync-noidle workload in the presence of RT tasks. o This patch gets rid of that exception and which workload to run with-in class always depends on lowest rb_key across service trees. The reason being that now we have multiple BE class groups and if we always switch to sync-noidle workload with-in group, we can potentially starve a sync-idle workload with-in group. Same is true for async workload which will be in root group. Also the workload-switching with-in group will become very unpredictable as it now depends whether some RT workload was running in the system or not.

We used to add reflinked file's inode to inode hash when we add it to the dest dir. But actually there is a race. Consider the following sequence. 1. reflink happens and create the inode in orphan dir. 2. reflink thread is scheduled out because of some io. 3. recovery begins to work and calls ocfs2_recover_orphans. It calls ocfs2_iget and get a new inode and i_count = 1. It calls iput then and delete inode. the buffer's uptodate state is cleared. This patch move insert_inode_hash to the create function so that it can be found by step 3 and prevented from deleting because i_count > 1.

The function essentially creates a copy of old array sans one element and replaces the references to elements of original (they are on cyclic lists) with those to corresponding elements of new one. After that the old one is fair game for freeing. First of all, there's a dumb braino: when we get to list_replace_init we use indices for wrong arrays - position in new one with the old array and vice versa. Another bug is more subtle - termination condition is wrong if the element to be excluded happens to be the last one. We shouldn't go until we fill the new array, we should go until we'd finished the old one. Otherwise the element we are trying to kill will remain on the cyclic lists... That crap used to be masked by several leaks, so it was not quite trivial to hit. Eric had fixed some of those leaks a while ago and the shit had hit the fan...

When a device is resumed following a system sleep, the core decrements the device's runtime PM usage counter but doesn't issue an idle notification if the counter reaches 0. This could prevent an otherwise unused device from being runtime-suspended again after the system sleep. The fix is to call pm_runtime_put_sync() instead of pm_runtime_put_noidle().

The codec chip is placed into low-power mode generically, but this doesn't turn off any external hardware connected to it, in particular external amplifiers. This patch creates a hook function that is called by the codec suspend/resume functions. It ought to disable any external hardware in a device-specific way. I've implemented a generic ALC889 function that sets the EAPD pin properly, and used it for the Acer Aspire 8930G which can benefit from this feature. On my laptop, this results in ~0.5W extra savings.

The idea is that once the module is loaded there is no need for the device to consume power until the interface is brought up. With the current solution the device is only powered up during EEPROM read, and then so also only if the EEPROM type is OTP. We have found that on certain platforms even non-OTP devices require power to be up during EEPROM read. On these platforms the driver never loads and the system log contains the following: iwlagn 0000:03:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x080403D8 We thus now power up all devices during EEPROM read. Signed-off-by: Reinette Chatre Signed-off-by: John W.

Change them to the size of the copied data. Furthermore, iveiv_entry is a local structure that has just been initialized and is not visible outside this function. Thus, there would seem to be no point to copy data into it. The order of the arguments is thus changed to copy the data into the parameters, which are provided as pointers, suggesting in this case that they should be used to return values.

I've had arguments about this code with people before, but always conceded they were right because removing it only made things not work at all on big endian platforms. However, analysing a failure of the OTP reading code, I now finally figured out what is going on, and why my intuition about that code being wrong was right all along. It turns out that the 'priv->eeprom' u8 array really wants to have the data in it in little endian. So the force code above and all really converts *to* little endian, not from it. Cf., for instance, the function iwl_eeprom_query16() -- it reads two u8 values and combines them into a u16, in a little-endian way. And considering it more, it makes sense to have the eeprom array as on the device, after all not all values really are 16-bit values, the MAC address for instance is not. Now, what this really means is that all the annotations are completely wrong. The eeprom reading code should fill the priv->eeprom array as a __le16 array, with __le16 values. This also means that iwl_read_otp_word() should really have a __le16 pointer as the data argument, since it should be filling that in a format suitable for priv->eeprom. Propagating these changes throughout, iwl_find_otp_image() is found to be, now obviously visible, defective -- it uses the data returned by iwl_read_otp_word() directly as if it was CPU endianness. Fixing that, which is this hunk of the patch: - next_link_addr = link_value * sizeof(u16); + next_link_addr = le16_to_cpu(link_value) * sizeof(u16); is the only real change of this patch. Everything else is just fixing the sparse annotations. Also, the bug only shows up on big endian platforms with a 1000 series card. 5000 and previous series do not use OTP, and 6000 series has shadow RAM support which means we don't ever use the defective code on any cards but 1000.

Instead of overwriting the SM PS settings with the local bits, we need to keep the remote bits. The bug was part of the original HT code from over two years ago, but unfortunately nobody noticed that it makes no sense -- we shouldn't be overwriting the peer's setting with our own but rather keep it intact when masking the peer capabilities with our own. While fixing that, I noticed that the masking of capabilities is completely useless for most of the bits, so also fix those other bits. Finally, I also noticed that PSMP_SUPPORT no longer exists in the final 802.11n version, so also remove that. Signed-off-by: Johannes Berg Signed-off-by: John W.

Unfortunately, the DSDT methods we are trying to call are part of the EC initialization, which happens very early, and the the dynamic SSDT is only loaded when a processor _PDC method runs much later. This results in namespace lookup errors for the (as of yet) undefined methods. Since Windows doesn't have any issues with this machine, we take it as a hint that they must be evaluating _PDC much earlier than we are. Thus, the proper thing for Linux to do should be to match the Windows implementation more closely. Provide a mechanism to call _PDC before we enable the EC.

Quoting John: "Petr Titěra reported an issue where he saw odd atime regressions with 2.6.33 where there were a full second worth of nanoseconds in the nanoseconds field. He also reviewed the time code and narrowed down the problem: unhandled overflow of the nanosecond field caused by rounding up the sub-nanosecond accumulated time. Details: * At the end of update_wall_time(), we currently round up the sub-nanosecond portion of accumulated time when storing it into xtime. This was added to avoid time inconsistencies caused when the sub-nanosecond portion was truncated when storing into xtime. Unfortunately we don't handle the possible second overflow caused by that rounding. * Previously the xtime_cache code hid this overflow by normalizing the xtime value when storing into the xtime_cache. * We could try to handle the second overflow after the rounding up, but since this affects the timekeeping's internal state, this would further complicate the next accumulation cycle, causing small errors in ntp steering. As much as I'd like to get rid of it, the xtime_cache code is known to work. * The correct fix is really to include the sub-nanosecond portion in the timekeeping accessor function, so we don't need to round up at during accumulation. This would greatly simplify the accumulation code. Unfortunately, we can't do this safely until the last three non-GENERIC_TIME arches (sparc32, arm, cris) are converted (those patches are in -mm) and we kill off the spots where arches set xtime directly. This is all 2.6.34 material, so I think reverting the xtime_cache change is the best approach for now. Many thanks to Petr for both reporting and finding the issue!"

The current kernel fifo API is not very widely used, because it has to many constrains. Only 17 files in the current 2.6.31-rc5 used it. FIFO's are like list's a very basic thing and a kfifo API which handles the most use case would save a lot of development time and memory resources. I think this are the reasons why kfifo is not in use: - The API is to simple, important functions are missing - A fifo can be only allocated dynamically - There is a requirement of a spinlock whether you need it or not - There is no support for data records inside a fifo So I decided to extend the kfifo in a more generic way without blowing up the API to much. The new API has the following benefits: - Generic usage: For kernel internal use and/or device driver. - Provide an API for the most use case. - Slim API: The whole API provides 25 functions. - Linux style habit. - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros - Direct copy_to_user from the fifo and copy_from_user into the fifo. - The kfifo itself is an in place member of the using data structure, this save an indirection access and does not waste the kernel allocator. - Lockless access: if only one reader and one writer is active on the fifo, which is the common use case, no additional locking is necessary. - Remove spinlock - give the user the freedom of choice what kind of locking to use if one is required. - Ability to handle records. Three type of records are supported: - Variable length records between 0-255 bytes, with a record size field of 1 bytes. - Variable length records between 0-65535 bytes, with a record size field of 2 bytes. - Fixed size records, which no record size field. - Preserve memory resource. - Performance! - Easy to use! This patch: Since most users want to have the kfifo as part of another object, reorganize the code to allow including struct kfifo in another data structure. This requires changing the kfifo_alloc and kfifo_init prototypes so that we pass an existing kfifo pointer into them. This patch changes the implementation and all existing users.

It removes the __must_check attribute from kfifo_in() and kfifo_in_locked() which must not necessary performed. Fix the allocation bug in the nozomi driver file, by moving out the kfifo_alloc from the interrupt handler into the probe function. Fix the kfifo_out() and kfifo_out_locked() users to handle a unexpected end of fifo.

We could just throw in an extra barrier to the data disk whenever we send a barrier to the journal disk, but that's not always strictly necessary. We only need to send a barrier during a commit when there are data blocks which are must be written out due to an inode written in ordered mode, or if fsync() depends on the commit to force data blocks to disk. Finally, before we drop transactions from the beginning of the journal during a checkpoint operation, we need to guarantee that any blocks that were flushed out to the data disk are firmly on the rust platter before we drop the transaction from the journal.

This means what inode_reservation must always be in sync with dquot->dq_dqb.dqb_rsvspace. Otherwise dquot_transfer() will result in incorrect quota(WARN_ON in dquot_claim_reserved_space() will be triggered) This is not easy because of complex locking order issues for example http://bugzilla.kernel.org/show_bug.cgi?id=14739 The patch introduce quota reservation field for each fs-inode (fs specific inode is used in order to prevent bloating generic vfs inode). This reservation is managed by quota code internally similar to i_blocks/i_bytes and may not be always in sync with internal fs reservation. Also perform some code rearrangement: - Unify dquot_reserve_space() and dquot_reserve_space() - Unify dquot_release_reserved_space() and dquot_free_space() - Also this patch add missing warning update to release_rsv() dquot_release_reserved_space() must call flush_warnings() as dquot_free_space() does.

The loop contains gotos to cleanup, which also frees b_entry_name and buffer. Some of these gotos are before the reinitializations of b_entry_name and buffer. To maintain the invariant that b_entry_name and buffer are NULL at the top of the loop, and thus acceptable arguments to kfree, these variables are now set to NULL after the kfrees. This seems to be the simplest solution. A more complicated solution would be to introduce more labels in the error handling code at the end of the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @r@ identifier E; expression E1; iterator I; statement S; @@ *kfree(E); ... when != E = E1 when != I(E,...)

Writing out delalloc data will convert those worst-case predictions into usually smaller actual usage, freeing up space before we hit ENOSPC based on this speculation. Thanks to Jens for the suggestion for the helper function, & the naming help. I've made the helper return status on whether writeback was started even though I don't plan to use it in the ext4 patch; it seems like it would be potentially useful to test this in some cases.

This is because we reserve worst-case metadata for delalloc writes, and when data is allocated that worst-case reservation is not usually needed. When freespace is low, kicking off an async writeback will start converting that worst-case space usage into something more realistic, almost always freeing up space to continue. This resolves the testcase for me, and survives all 4 generic ENOSPC tests in xfstests. We'll still need a hard synchronous sync to squeeze out the last bit, but this fixes things up to a large degree.

Thanks to Olivier Croset for reporting the problem about __BIG_ENDIAN compiling problem and send a relative patch. The suspend/resume and blank support are contributed by Jason from Silicon Motion Technology.

The most - common example is TCP over IP, which allows to pass through firewalls and - create remote backup storage in a different datacenter. DST requires - single port to be enabled on the exporting node and outgoing connections - on the local node. - - DST works with in-kernel client and server, which improves performance by - eliminating unneded data copies and by not depending on the version - of the external IO components. It requires userspace configuration utility - though. - - DST uses transaction model, when each store has to be explicitly acked - from the remote node to be considered as successfully written. There - may be lots of in-flight transactions. When remote host does not ack - the transaction it will be resent predefined number of times with specified - timeouts between them. All those parameters are configurable. Transactions - are marked as failed after all resends complete unsuccessfully; having - long enough resend timeout and/or large number of resends allows not to - return error to the higher (FS usually) layer in case of short network - problems or remote node outages. In case of network RAID setup this means - that storage will not degrade until transactions are marked as failed, and - thus will not force checksum recalculation and data rebuild. In case of - connection failure DST will try to reconnect to the remote node automatically. - DST sends ping commands at idle time to detect if remote node is alive. - - Because of transactional model it is possible to use zero-copy sending - without worry of data corruption (which in turn could be detected by the - strong checksums though). - - DST may fully encrypt the data channel in case of untrusted channel and implement - strong checksum of the transferred data. It is possible to configure algorithms - and crypto keys; they should match on both sides of the network channel. - Crypto processing does not introduce noticeble performance overhead, since DST - uses configurable pool of threads to perform crypto processing. - - DST utilizes memory pool model of all its transaction allocations (it is the - only additional allocation on the client) and server allocations (bio pools, - while pages are allocated from the slab). - - At startup DST performs a simple negotiation with the export node to determine - access permissions and size of the exported storage. It can be extended if - new parameters should be autonegotiated. - - DST carries block IO flags in the protocol, which allows to transparently implement - barriers and sync/flush operations. Those flags are used in the export node where - IO against the local storage is performed, which means that sync write will be sync - on the remote node too, which in turn improves data integrity and improved resistance - to errors and data corruption during power outages or storage damages. - - Homepage: http://www.ioremap.net/projects/dst - Userspace configuration utility and the latest releases: http://www.ioremap.net/archive/dst/ - -config DST_DEBUG - bool "DST debug" - depends on DST - ---help--- - This option will enable HEAVY debugging of the DST. - Turn it on ONLY if you have to debug some really obscure problem. diff --git a/drivers/staging/dst/Makefile b/drivers/staging/dst/Makefile deleted file mode 100644 index 3a8b0cf9643e..000000000000 --- a/drivers/staging/dst/Makefile +++ /dev/null @@ -1,3 +0,0 @@ -obj-$(CONFIG_DST) += nst.o - -nst-y := dcore.o state.o export.o thread_pool.o crypto.o trans.o diff --git a/drivers/staging/dst/crypto.c b/drivers/staging/dst/crypto.c deleted file mode 100644 index 351295c97a4b..000000000000 --- a/drivers/staging/dst/crypto.c +++ /dev/null @@ -1,733 +0,0 @@ -/* - * 2007+ Copyright (c) Evgeniy Polyakov - * All rights reserved. - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The driver would still send the data to comedi but the reader won't wake up any more. What's required is setting the flag COMEDI_CB_BLOCK after new data has arrived which wakes up the reader and therefore the read() command.

Advantage is that new device ID submissions will now have a specific (sorted) position - less future merge conflicts. Compile-tested, based on _current_ mainline git. Minor checkpatch.pl warnings were eliminated whereever it made sense, very minor text changes.

This way there is a guarantee the syslog won't be flooded for any sane program. The original attempt at this made the tables non const and stored the flag inline. Linus suggested using a separate hash table for this, this is based on a code snippet from him. The hash implies this is not exact and can sometimes not print a new sysctl due to a hash collision, but in practice this should not be a problem I used a FNV32 hash over the binary string with a 32byte bitmap. This gives relatively little collisions when all the predefined binary sysctls are hashed: size 256 bucket length number 0: [25] 1: [67] 2: [88] 3: [47] 4: [22] 5: [6] 6: [1] The worst case is a single collision of 6 hash values.

It's just wrong, and broke resume for Rafael even on a non-AMD CPU. As Rafael says: "... it causes microcode_init_cpu() to be called during resume even for CPUs for which there's no microcode to apply. That, in turn, results in executing request_firmware() (on Intel CPUs at least) which doesn't work at this stage of resume (we have device interrupts disabled, I/O devices are still suspended and so on). If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is known to us" , so before commit 9f15226e755 microcode_resume_cpu() was called for all CPUs already in the system during suspend, which was the right thing to do. The commit changed it so that the CPUs without microcode to apply are now treated as "unknown", which is not quite right. The problem this commit attempted to solve has to be handled differently."

(i2c-omap: OMAP3: PM: (re)init for every transfer to support off-mode) introduced a change which make the dev->iestate contents be written to the OMAP_I2C_IE_REG every time omap_i2c_unidle is called. Previously, the state was only written if it wasn't equal to zero. In omap_i2c_probe, omap_i2c_unidle() is called prior to omap_i2c_init(), in which case dev->iestate has not yet been initialized and will be set to zero. Having this value written to the registers causes deadlock while booting. As such, this change restores the original functionality.

Due to this, lock up issues are reported during timeout/error cases. This patch fixes above issue by disabling I2C controller as per OMAP3430 TRM for soft reset. As per TRM, I2C controller needs to be disabled as a first step during soft reset. Here is correct soft reset sequence: a. Ensure that the module is disabled (clear the I2Ci.I2C_CON[15] I2C_EN bit to 0). b. Set the I2Ci.I2C_SYSC[1] SRST bit to 1. c. Enable the module by setting I2Ci.I2C_CON[15] I2C_EN bit to 1. d. Check the I2Ci.I2C_SYSS[0] RDONE bit until it is set to 1 to indicate the software reset is complete.

However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43 ("dock: make dock driver not a module") removed the possibility of having CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when CONFIG_ATA_ACPI=y. This makes the kernel ~5 Kb smaller for people who don't have a dock by allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y. Signed-off-by: Carlos R.

They are caused by calling napi_disable() (with msleep()). This patch fixes it by moving most of the timer content to the workqueue function (similarly to other drivers, like tg3), with spin_lock() changed to BH version. Additionally, there is spin_lock_irq() moved in rhine_close() to exclude napi_disable() etc., also tg3's way.

The root cause is, device 0 "reuses" the same stream tag that was used by device 3, and the "intelhdmi - sticky stream id" patch leaves the HDMI codec in a functional state. So the HDMI codec happily accepts the audio samples which reuse its stream tag. The proposed solution is to remember the last device each azx_dev was assigned to, and prefer to 1) reuse the azx_dev (and hence the stream tag) the HDMI codec last used 2) or assign a never-used azx_dev for HDMI With this patch and the above two speaker-test commands, HDMI codec will use stream tag 8 and Analog codec will use 5. The stream tag used by HDMI codec won't be reused by others, as long as we don't run out of the 4 playback azx_dev's. The legacy Analog codec will continue to use stream tag 5 because its device id is 0 (this is a bit tricky).

The OS could have other mechanisms to prevent a present translation from being used, which the hypervisor is unaware of.

However, the calibration interval isn't initialized before interrupts are enabled, so we can have a situation where an interrupt occurs before the interval is assigned, so the interval is actually negative. As a result, the ISR will arm a software interrupt to schedule the tasklet, and then rearm it when the SWI is processed, and so on, leading to a softlockup at modprobe time. Move the initialization order around so the calibration interval is set before interrupts are active. Another possible fix is to schedule the tasklet directly from the poll routine, but I think there are additional plans for the SWI.

In that case, it may happen that mac80211 tries to report the assoc success to cfg80211, but gets blocked on the wdev lock that is held because the user is requesting the deauth. The result is that we run into a warning. This is mostly harmless, but maybe cause an unexpected event to be sent to userspace; we'd send an assoc success event although userspace was no longer expecting that. To fix this, remove the warning and check whether the race happened and in that case abort processing.

If such calls are made, however, suspend can end up throwing hardware in an unexpected state and making the device unusable upon resume. Fix this by preventing mac80211 to schedule dynamic_ps_disable_work by checking for when mac80211 starts to suspend and starts quiescing. Frames should be allowed to go through though as that is part of the quiescing steps and we do not flush the mac80211 workqueue since it was already done towards the beginning of suspend cycle. The other mac80211 issue will be hanled in the next patch. For further details see refer to the thread: http://marc.info/?t=126144866100001&r=1&w=2 Cc: stable@kernel.org Signed-off-by: Luis R.

For suspend and resume this is important due to all the possible issues that can come out of the suspend <-> resume cycle. Not propagating the error means cfg80211 will assume the resume for the device went through fine and mac80211 will continue on trying to poke at the hardware, enable timers, queue work, and so on for a device which is completley unfunctional. The least we can do is to propagate device start issues and warn when this occurs upon resume. A side effect of this patch is we also now propagate the start errors upon harware reconfigurations (non-suspend), but this should also be desirable anyway, there is not point in continuing to reconfigure a device if mac80211 was unable to start the device.

This affected kernelspace and userspace drivers alike and was caused by firewire-core's inability to accept multiple registrations of FCP listeners. The fix allows multiple address handlers to be registered for the FCP command and response registers. When a request for these registers is received, all handlers are invoked, and the Firewire response is generated by the core and not by any handler. The cdev API does not change, i.e., userspace is still expected to send a response for FCP requests; this response is silently ignored.

There are two reasons to do so: - Packet-per-buffer mode and dual-buffer mode do not behave the same under certain circumstances, notably if several packets are covered by a single fw_cdev_iso_packet descriptor. http://marc.info/?l=linux1394-devel&m=124965653718313 Therefore the driver stack should not silently choose one or the other mode but should leave the choice to the high-level driver (regardless if kernel driver or userspace driver). Or simply always only offer packet-per-buffer mode, since a considerable number of controllers, even current ones, does not offer dual-buffer support. - Even under circumstances where packet-per-buffer mode and dual-buffer mode behave exactly the same --- notably when used through libraw1394, libdc1394, as well as the current two kernel drivers which use isochronous reception (firewire-net and firedtv) --- we are still faced with the problem that several OHCI 1.1 controllers have bugs in dual-buffer mode. Although it looks like we have identified most of those buggy controllers by now, we cannot be quite sure about that. So, use packet-per-buffer by default from now on. This change should be followed up by a more complete solution: Either extend the in-kernel API and the userspace ABI by a choice between the two IR modes or remove all dual-buffer related code from firewire-ohci.

The linux1394.org domain has been dead for a while and is no longer under control of a Linux developer. The current web site of the Linux 1394 project is http://ieee1394.wiki.kernel.org/. The classic drivers/ieee1394/ stack is now obsolete from the development point of view, though still a useful alternative in productive use. But nobody should attempt to submit style cleanup patches for it or to develop new drivers on top of this stack, hence mark its MAINTAINERS entry as Obsolete. drivers/ieee1394/raw1394*, like the rest of the old stack, does not receive bigger code changes anymore, hence shrink the MAINTAINERS database a bit by dropping raw1394's special entry. If something important and urgent is going to come up for raw1394, I will make sure that Dan will be notified of it besides via linux1394-devel.

However, do not label ieee1394 as "Obsolete" yet, as the newer drivers have not been deployed as default stack in the majority of Linux distributions yet, and those who start doing so now may still want to install the old drivers as fallback for unforeseen issues. Since Linux 2.6.32, FireWire audio devices can be driven by the newer firewire driver stack too, hence remove an outdated comment about audio devices. Also remove comments about library versions since the 2nd generation of libraw1394 and libdc1394 is now in common use; details on library versions can be read at the wiki link from the help texts.

Since 2.6.29, the device can disappear after the 'close' unless a significant configuration has happened to the device. The change made by "SET_ARRAY_INFO" can too minor to stop the device from disappearing, but important enough that losing the change is bad. So: make sure SET_ARRAY_INFO sets mddev->ctime, and keep the device active as long as ctime is non-zero (it gets zeroed with lots of other things when the array is stopped). This is suitable for -stable kernels since 2.6.29.

This ensures that no resync/recovery happens until something else writes to the device. This is important for resume-from-disk off an md array. However if an array is started 'readonly' (by writing 'readonly' to the 'array_state' sysfs attribute) we want it to be really 'readonly', not 'auto-readonly'. So strengthen the condition to only set auto-readonly if the array is not already read-only.

The root cause of this BUG() was caused by the fact that ext4_calc_metadata_amount() can severely over-estimate how many metadata blocks will be needed, especially when using direct block-mapped files. In addition, it can also badly *under* estimate how much space is needed, since ext4_calc_metadata_amount() assumes that the blocks are contiguous, and this is not always true. If the application is writing blocks to a sparse file, the number of metadata blocks necessary can be severly underestimated by the functions ext4_da_reserve_space(), ext4_da_update_reserve_space() and ext4_da_release_space(). This was the cause of the dq_claim_space reports found on kerneloops.org. Unfortunately, doing this right means that we need to massively over-estimate the amount of free space needed. So in some cases we may need to force the inode to be written to disk asynchronously in to avoid spurious quota failures. http://bugzilla.kernel.org/show_bug.cgi?id=14936 Signed-off-by: "Theodore Ts'o" --- fs/ext4/inode.c | 157 ++++++++++++++++++++++++++++++-------------------------- 1 file changed, 84 insertions(+), 73 deletions(-) diff --git a/fs/ext4/inode.c b/fs/ext4/inode.c index 3e3b45458ef8..84eeb8f515a3 100644 --- a/fs/ext4/inode.c +++ b/fs/ext4/inode.c @@ -1043,43 +1043,47 @@ static int ext4_calc_metadata_amount(struct inode *inode, int blocks) return ext4_indirect_calc_metadata_amount(inode, blocks); } +/* + * Called with i_data_sem down, which is important since we can call + * ext4_discard_preallocations() from here. + */ static void ext4_da_update_reserve_space(struct inode *inode, int used) { struct ext4_sb_info *sbi = EXT4_SB(inode->i_sb); - int total, mdb, mdb_free, mdb_claim = 0; - - spin_lock(&EXT4_I(inode)->i_block_reservation_lock); - /* recalculate the number of metablocks still need to be reserved */ - total = EXT4_I(inode)->i_reserved_data_blocks - used; - mdb = ext4_calc_metadata_amount(inode, total); - - /* figure out how many metablocks to release */ - BUG_ON(mdb > EXT4_I(inode)->i_reserved_meta_blocks); - mdb_free = EXT4_I(inode)->i_reserved_meta_blocks - mdb; - - if (mdb_free) { - /* Account for allocated meta_blocks */ - mdb_claim = EXT4_I(inode)->i_allocated_meta_blocks; - BUG_ON(mdb_free < mdb_claim); - mdb_free -= mdb_claim; - - /* update fs dirty blocks counter */ + struct ext4_inode_info *ei = EXT4_I(inode); + int mdb_free = 0; + + spin_lock(&ei->i_block_reservation_lock); + if (unlikely(used > ei->i_reserved_data_blocks)) { + ext4_msg(inode->i_sb, KERN_NOTICE, "%s: ino %lu, used %d " + "with only %d reserved data blocks\n", + __func__, inode->i_ino, used, + ei->i_reserved_data_blocks); + WARN_ON(1); + used = ei->i_reserved_data_blocks; + } + + /* Update per-inode reservations */ + ei->i_reserved_data_blocks -= used; + used += ei->i_allocated_meta_blocks; + ei->i_reserved_meta_blocks -= ei->i_allocated_meta_blocks; + ei->i_allocated_meta_blocks = 0; + percpu_counter_sub(&sbi->s_dirtyblocks_counter, used); + + if (ei->i_reserved_data_blocks == 0) { + /* + * We can release all of the reserved metadata blocks + * only when we have written all of the delayed + * allocation blocks. + */ + mdb_free = ei->i_allocated_meta_blocks; percpu_counter_sub(&sbi->s_dirtyblocks_counter, mdb_free); - EXT4_I(inode)->i_allocated_meta_blocks = 0; - EXT4_I(inode)->i_reserved_meta_blocks = mdb; + ei->i_allocated_meta_blocks = 0; } - - /* update per-inode reservations */ - BUG_ON(used > EXT4_I(inode)->i_reserved_data_blocks); - EXT4_I(inode)->i_reserved_data_blocks -= used; - percpu_counter_sub(&sbi->s_dirtyblocks_counter, used + mdb_claim); spin_unlock(&EXT4_I(inode)->i_block_reservation_lock); - vfs_dq_claim_block(inode, used + mdb_claim); - - /* - * free those over-booking quota for metadata blocks - */ + /* Update quota subsystem */ + vfs_dq_claim_block(inode, used); if (mdb_free) vfs_dq_release_reservation_block(inode, mdb_free); @@ -1088,7 +1092,8 @@ static void ext4_da_update_reserve_space(struct inode *inode, int used) * there aren't any writers on the inode, we can discard the * inode's preallocations. */ - if (!total && (atomic_read(&inode->i_writecount) == 0)) + if ((ei->i_reserved_data_blocks == 0) && + (atomic_read(&inode->i_writecount) == 0)) ext4_discard_preallocations(inode); } @@ -1801,7 +1806,8 @@ static int ext4_da_reserve_space(struct inode *inode, int nrblocks) { int retries = 0; struct ext4_sb_info *sbi = EXT4_SB(inode->i_sb); - unsigned long md_needed, mdblocks, total = 0; + struct ext4_inode_info *ei = EXT4_I(inode); + unsigned long md_needed, md_reserved, total = 0; /* * recalculate the amount of metadata blocks to reserve @@ -1809,35 +1815,44 @@ static int ext4_da_reserve_space(struct inode *inode, int nrblocks) * worse case is one extent per block */ repeat: - spin_lock(&EXT4_I(inode)->i_block_reservation_lock); - total = EXT4_I(inode)->i_reserved_data_blocks + nrblocks; - mdblocks = ext4_calc_metadata_amount(inode, total); - BUG_ON(mdblocks < EXT4_I(inode)->i_reserved_meta_blocks); - - md_needed = mdblocks - EXT4_I(inode)->i_reserved_meta_blocks; + spin_lock(&ei->i_block_reservation_lock); + md_reserved = ei->i_reserved_meta_blocks; + md_needed = ext4_calc_metadata_amount(inode, nrblocks); total = md_needed + nrblocks; - spin_unlock(&EXT4_I(inode)->i_block_reservation_lock); + spin_unlock(&ei->i_block_reservation_lock); /* * Make quota reservation here to prevent quota overflow * later.

On suspend: - PM core starts suspending devices, ucc_geth_suspend gets called; - ucc_geth calls phy_stop() on suspend. Note that phy_stop() is mostly asynchronous so it doesn't block ucc_geth's suspend routine, it just sets PHY_HALTED state and disables PHY's interrupts; - Suddenly the state machine gets scheduled, it grabs the phydev->lock mutex and tries to process the PHY_HALTED state, so it calls phydev->adjust_link(phydev->attached_dev). In ucc_geth case adjust_link() calls msleep(), which reschedules the code flow back to PM core, which now finishes suspend and so we end up sleeping with phydev->lock mutex held. On resume: - PM core starts resuming devices (notice that nobody rescheduled the state machine yet, so the mutex is still held), the core calls ucc_geth's resume routine; - ucc_geth_resume restarts the PHY with phy_stop()/phy_start() sequence, and the phy_*() calls are trying to grab the phydev->lock mutex. Here comes the deadlock. This patch fixes the issue by stopping the state machine on suspend and starting it again on resume. Signed-off-by: Anton Vorontsov Signed-off-by: David S.

This didn't matter as much when functions which managed the reserved metadata blocks were more aggressive about dropping reserved metadata blocks as delayed allocation blocks were written, but unfortunately they were too aggressive. This was fixed in commit 0637c6f, but as a result the over-estimation by ext4_calc_metadata_amount() would lead to reserving 2-3 times the number of pending delayed allocation blocks as potentially required metadata blocks. So if there are 1 megabytes of blocks which have been not yet been allocation, up to 3 megabytes of space would get reserved out of the user's quota and from the file system free space pool until all of the inode's data blocks have been allocated. This commit addresses this problem by much more accurately estimating the number of metadata blocks that will be required. It will still somewhat over-estimate the number of blocks needed, since it must make a worst case estimate not knowing which physical blocks will be needed, but it is much more accurate than before.

Later on, we may relax the reiserfs lock for various reasons, this creates inverted dependencies. We can remove the reiserfs lock -> i_mutex dependency by relaxing the former before calling open_xa_dir(). This is fine because the lookup and creation of xattr private directories done in open_xa_dir() are covered by the targeted inode mutexes. And deeper operations in the tree are still done under the write lock.

This is needed so that e.g. PCI devices can -access with a Single Address Cycle (32bit DMA address) any page in the -64bit physical address space. Previously in Linux those 64bit -platforms had to set artificial limits on the maximum RAM size in the -system, so that the virt_to_bus() static scheme works (the DMA address -translation tables were simply filled on bootup to map each bus -address to the physical page __pa(bus_to_virt())). - -So that Linux can use the dynamic DMA mapping, it needs some help from the -drivers, namely it has to take into account that DMA addresses should be -mapped only for the time they are actually used and unmapped after the DMA -transfer. - -The following API will work of course even on platforms where no such -hardware exists, see e.g. arch/x86/include/asm/pci.h for how it is implemented on -top of the virt_to_bus interface. - -First of all, you should make sure - -#include - -is in your driver.

There has been an unwritten -set of rules regarding this, and this text is an attempt to finally -write them down. - -If you acquired your memory via the page allocator -(i.e. __get_free_page*()) or the generic memory allocators -(i.e. kmalloc() or kmem_cache_alloc()) then you may DMA to/from -that memory using the addresses returned from those routines. - -This means specifically that you may _not_ use the memory/addresses -returned from vmalloc() for DMA. It is possible to DMA to the -_underlying_ memory mapped into a vmalloc() area, but this requires -walking page tables to get the physical addresses, and then -translating each of those pages back to a kernel address using -something like __va(). [ EDIT: Update this when we integrate -Gerd Knorr's generic code which does this. ] - -This rule also means that you may use neither kernel image addresses -(items in data/text/bss segments), nor module image addresses, nor -stack addresses for DMA. These could all be mapped somewhere entirely -different than the rest of physical memory. Even if those classes of -memory could physically work with DMA, you'd need to ensure the I/O -buffers were cacheline-aligned. Without that, you'd see cacheline -sharing problems (data corruption) on CPUs with DMA-incoherent caches. -(The CPU could write to one word, DMA would write to a different one -in the same cache line, and one of them could be overwritten.) - -Also, this means that you cannot take the return of a kmap() -call and DMA to/from that. This is similar to vmalloc(). - -What about block I/O and networking buffers? The block I/O and -networking subsystems make sure that the buffers they use are valid -for you to DMA from/to. - - DMA addressing limitations - -Does your device have any DMA addressing limitations? For example, is -your device only capable of driving the low order 24-bits of address -on the PCI bus for SAC DMA transfers? If so, you need to inform the -PCI layer of this fact. - -By default, the kernel assumes that your device can address the full -32-bits in a SAC cycle. For a 64-bit DAC capable device, this needs -to be increased. And for a device with limitations, as discussed in -the previous paragraph, it needs to be decreased. - -pci_alloc_consistent() by default will return 32-bit DMA addresses. -PCI-X specification requires PCI-X devices to support 64-bit -addressing (DAC) for all transactions. And at least one platform (SGI -SN2) requires 64-bit consistent allocations to operate correctly when -the IO bus is in PCI-X mode. Therefore, like with pci_set_dma_mask(), -it's good practice to call pci_set_consistent_dma_mask() to set the -appropriate mask even if your device only supports 32-bit DMA -(default) and especially if it's a PCI-X device. - -For correct operation, you must interrogate the PCI layer in your -device probe routine to see if the PCI controller on the machine can -properly support the DMA addressing limitation your device has.

It returns zero if your card can perform DMA -properly on the machine given the address mask you provided. - -If it returns non-zero, your device cannot perform DMA properly on -this platform, and attempting to do so will result in undefined -behavior. You must either use a different mask, or not use DMA. - -This means that in the failure case, you have three options: - -1) Use another DMA mask, if possible (see below). -2) Use some non-DMA mode for data transfer, if possible. -3) Ignore this device and do not initialize it. - -It is recommended that your driver print a kernel KERN_WARNING message -when you end up performing either #2 or #3. In this manner, if a user -of your driver reports that performance is bad or that the device is not -even detected, you can ask them for the kernel messages to find out -exactly why. - -The standard 32-bit addressing PCI device would do something like -this: - - if (pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) { - printk(KERN_WARNING - "mydev: No suitable DMA available.\n"); - goto ignore_this_device; - } - -Another common scenario is a 64-bit capable device. The approach -here is to try for 64-bit DAC addressing, but back down to a -32-bit mask should that fail. The PCI platform code may fail the -64-bit mask not because the platform is not capable of 64-bit -addressing. Rather, it may fail in this case simply because -32-bit SAC addressing is done more efficiently than DAC addressing. -Sparc64 is one platform which behaves in this way. - -Here is how you would handle a 64-bit capable device which can drive -all 64-bits when accessing streaming DMA: - - int using_dac; - - if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(64))) { - using_dac = 1; - } else if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) { - using_dac = 0; - } else { - printk(KERN_WARNING - "mydev: No suitable DMA available.\n"); - goto ignore_this_device; - } - -If a card is capable of using 64-bit consistent allocations as well, -the case would look like this: - - int using_dac, consistent_using_dac; - - if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(64))) { - using_dac = 1; - consistent_using_dac = 1; - pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(64)); - } else if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) { - using_dac = 0; - consistent_using_dac = 0; - pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(32)); - } else { - printk(KERN_WARNING - "mydev: No suitable DMA available.\n"); - goto ignore_this_device; - } - -pci_set_consistent_dma_mask() will always be able to set the same or a -smaller mask as pci_set_dma_mask(). However for the rare case that a -device driver only uses consistent allocations, one would have to -check the return value from pci_set_consistent_dma_mask(). - -Finally, if your device can only drive the low 24-bits of -address during PCI bus mastering you might do something like: - - if (pci_set_dma_mask(pdev, DMA_BIT_MASK(24))) { - printk(KERN_WARNING - "mydev: 24-bit DMA addressing not available.\n"); - goto ignore_this_device; - } - -When pci_set_dma_mask() is successful, and returns zero, the PCI layer -saves away this mask you have provided.

If your device supports multiple -functions (for example a sound card provides playback and record -functions) and the various different functions have _different_ -DMA addressing limitations, you may wish to probe each mask and -only provide the functionality which the machine can handle. It -is important that the last call to pci_set_dma_mask() be for the -most specific mask. - -Here is pseudo-code showing how this might be done: - - #define PLAYBACK_ADDRESS_BITS DMA_BIT_MASK(32) - #define RECORD_ADDRESS_BITS DMA_BIT_MASK(24) - - struct my_sound_card *card; - struct pci_dev *pdev; - - ... - if (!pci_set_dma_mask(pdev, PLAYBACK_ADDRESS_BITS)) { - card->playback_enabled = 1; - } else { - card->playback_enabled = 0; - printk(KERN_WARNING "%s: Playback disabled due to DMA limitations.\n", - card->name); - } - if (!pci_set_dma_mask(pdev, RECORD_ADDRESS_BITS)) { - card->record_enabled = 1; - } else { - card->record_enabled = 0; - printk(KERN_WARNING "%s: Record disabled due to DMA limitations.\n", - card->name); - } - -A sound card was used as an example here because this genre of PCI -devices seems to be littered with ISA chips given a PCI front end, -and thus retaining the 16MB DMA addressing limitations of ISA. - - Types of DMA mappings - -There are two types of DMA mappings: - -- Consistent DMA mappings which are usually mapped at driver - initialization, unmapped at the end and for which the hardware should - guarantee that the device and the CPU can access the data - in parallel and will see updates made by each other without any - explicit software flushing. - - Think of "consistent" as "synchronous" or "coherent". - - The current default is to return consistent memory in the low 32 - bits of the PCI bus space. However, for future compatibility you - should set the consistent mask even if this default is fine for your - driver. - - Good examples of what to use consistent mappings for are: - - - Network card DMA ring descriptors. - - SCSI adapter mailbox command data structures. - - Device firmware microcode executed out of - main memory. - - The invariant these examples all require is that any CPU store - to memory is immediately visible to the device, and vice - versa.

The CPU may reorder stores to - consistent memory just as it may normal memory.

If your -driver needs regions sized smaller than a page, you may prefer using -the pci_pool interface, described below. - -The consistent DMA mapping interfaces, for non-NULL pdev, will by -default return a DMA address which is SAC (Single Address Cycle) -addressable. Even if the device indicates (via PCI dma mask) that it -may address the upper 32-bits and thus perform DAC cycles, consistent -allocation will only return > 32-bit PCI addresses for DMA if the -consistent dma mask has been explicitly changed via -pci_set_consistent_dma_mask(). This is true of the pci_pool interface -as well. - -pci_alloc_consistent returns two values: the virtual address which you -can use to access it from the CPU and dma_handle which you pass to the -card. - -The cpu return address and the DMA bus master address are both -guaranteed to be aligned to the smallest PAGE_SIZE order which -is greater than or equal to the requested size. This invariant -exists (for example) to guarantee that if you allocate a chunk -which is smaller than or equal to 64 kilobytes, the extent of the -buffer you receive will not cross a 64K boundary. - -To unmap and free such a DMA region, you call: - - pci_free_consistent(pdev, size, cpu_addr, dma_handle); - -where pdev, size are the same as in the above call and cpu_addr and -dma_handle are the values pci_alloc_consistent returned to you. -This function may not be called in interrupt context. - -If your driver needs lots of smaller memory regions, you can write -custom code to subdivide pages returned by pci_alloc_consistent, -or you can use the pci_pool API to do that. A pci_pool is like -a kmem_cache, but it uses pci_alloc_consistent not __get_free_pages. -Also, it understands common hardware constraints for alignment, -like queue heads needing to be aligned on N byte boundaries. - -Create a pci_pool like this: - - struct pci_pool *pool; - - pool = pci_pool_create(name, pdev, size, align, alloc); - -The "name" is for diagnostics (like a kmem_cache name); pdev and size -are as above. The device's hardware alignment requirement for this -type of data is "align" (which is expressed in bytes, and must be a -power of two). If your device has no boundary crossing restrictions, -pass 0 for alloc; passing 4096 says memory allocated from this pool -must not cross 4KByte boundaries (but at that time it may be better to -go for pci_alloc_consistent directly instead). - -Allocate memory from a pci pool like this: - - cpu_addr = pci_pool_alloc(pool, flags, &dma_handle); - -flags are SLAB_KERNEL if blocking is permitted (not in_interrupt nor -holding SMP locks), SLAB_ATOMIC otherwise. Like pci_alloc_consistent, -this returns two values, cpu_addr and dma_handle. - -Free memory that was allocated from a pci_pool like this: - - pci_pool_free(pool, cpu_addr, dma_handle); - -where pool is what you passed to pci_pool_alloc, and cpu_addr and -dma_handle are the values pci_pool_alloc returned. This function -may be called in interrupt context. - -Destroy a pci_pool by calling: - - pci_pool_destroy(pool); - -Make sure you've called pci_pool_free for all memory allocated -from a pool before you destroy the pool. This function may not -be called in interrupt context. - - DMA Direction - -The interfaces described in subsequent portions of this document -take a DMA direction argument, which is an integer and takes on -one of the following values: - - PCI_DMA_BIDIRECTIONAL - PCI_DMA_TODEVICE - PCI_DMA_FROMDEVICE - PCI_DMA_NONE - -One should provide the exact DMA direction if you know it. - -PCI_DMA_TODEVICE means "from main memory to the PCI device" -PCI_DMA_FROMDEVICE means "from the PCI device to main memory" -It is the direction in which the data moves during the DMA -transfer. - -You are _strongly_ encouraged to specify this as precisely -as you possibly can. - -If you absolutely cannot know the direction of the DMA transfer, -specify PCI_DMA_BIDIRECTIONAL. It means that the DMA can go in -either direction. The platform guarantees that you may legally -specify this, and that it will work, but this may be at the -cost of performance for example. - -The value PCI_DMA_NONE is to be used for debugging. One can -hold this in a data structure before you come to know the -precise direction, and this will help catch cases where your -direction tracking logic has failed to set things up properly. - -Another advantage of specifying this value precisely (outside of -potential platform-specific optimizations of such) is for debugging. -Some platforms actually have a write permission boolean which DMA -mappings can be marked with, much like page protections in the user -program address space. Such platforms can and do report errors in the -kernel logs when the PCI controller hardware detects violation of the -permission setting. - -Only streaming mappings specify a direction, consistent mappings -implicitly have a direction attribute setting of -PCI_DMA_BIDIRECTIONAL. - -The SCSI subsystem tells you the direction to use in the -'sc_data_direction' member of the SCSI command your driver is -working on. - -For Networking drivers, it's a rather simple affair. For transmit -packets, map/unmap them with the PCI_DMA_TODEVICE direction -specifier. For receive packets, just the opposite, map/unmap them -with the PCI_DMA_FROMDEVICE direction specifier. - - Using Streaming DMA mappings - -The streaming DMA mapping routines can be called from interrupt -context. There are two versions of each map/unmap, one which will -map/unmap a single memory region, and one which will map/unmap a -scatterlist. - -To map a single region, you do: - - struct pci_dev *pdev = mydev->pdev; - dma_addr_t dma_handle; - void *addr = buffer->ptr; - size_t size = buffer->len; - - dma_handle = pci_map_single(pdev, addr, size, direction); - -and to unmap it: - - pci_unmap_single(pdev, dma_handle, size, direction); - -You should call pci_unmap_single when the DMA activity is finished, e.g. -from the interrupt which told you that the DMA transfer is done. - -Using cpu pointers like this for single mappings has a disadvantage, -you cannot reference HIGHMEM memory in this way. Thus, there is a -map/unmap interface pair akin to pci_{map,unmap}_single. These -interfaces deal with page/offset pairs instead of cpu pointers. -Specifically: - - struct pci_dev *pdev = mydev->pdev; - dma_addr_t dma_handle; - struct page *page = buffer->page; - unsigned long offset = buffer->offset; - size_t size = buffer->len; - - dma_handle = pci_map_page(pdev, page, offset, size, direction); - - ... - - pci_unmap_page(pdev, dma_handle, size, direction); - -Here, "offset" means byte offset within the given page. - -With scatterlists, you map a region gathered from several regions by: - - int i, count = pci_map_sg(pdev, sglist, nents, direction); - struct scatterlist *sg; - - for_each_sg(sglist, sg, count, i) { - hw_address[i] = sg_dma_address(sg); - hw_len[i] = sg_dma_len(sg); - } - -where nents is the number of entries in the sglist. - -The implementation is free to merge several consecutive sglist entries -into one (e.g. if DMA mapping is done with PAGE_SIZE granularity, any -consecutive sglist entries can be merged into one provided the first one -ends and the second one starts on a page boundary - in fact this is a huge -advantage for cards which either cannot do scatter-gather or have very -limited number of scatter-gather entries) and returns the actual number -of sg entries it mapped them to. On failure 0 is returned. - -Then you should loop count times (note: this can be less than nents times) -and use sg_dma_address() and sg_dma_len() macros where you previously -accessed sg->address and sg->length as shown above. - -To unmap a scatterlist, just call: - - pci_unmap_sg(pdev, sglist, nents, direction); - -Again, make sure DMA activity has already finished. - -PLEASE NOTE: The 'nents' argument to the pci_unmap_sg call must be - the _same_ one you passed into the pci_map_sg call, - it should _NOT_ be the 'count' value _returned_ from the - pci_map_sg call. - -Every pci_map_{single,sg} call should have its pci_unmap_{single,sg} -counterpart, because the bus address space is a shared resource (although -in some ports the mapping is per each BUS so less devices contend for the -same bus address space) and you could render the machine unusable by eating -all bus addresses. - -If you need to use the same streaming DMA region multiple times and touch -the data in between the DMA transfers, the buffer needs to be synced -properly in order for the cpu and device to see the most uptodate and -correct copy of the DMA buffer. - -So, firstly, just map it with pci_map_{single,sg}, and after each DMA -transfer call either: - - pci_dma_sync_single_for_cpu(pdev, dma_handle, size, direction); - -or: - - pci_dma_sync_sg_for_cpu(pdev, sglist, nents, direction); - -as appropriate. - -Then, if you wish to let the device get at the DMA area again, -finish accessing the data with the cpu, and then before actually -giving the buffer to the hardware call either: - - pci_dma_sync_single_for_device(pdev, dma_handle, size, direction); - -or: - - pci_dma_sync_sg_for_device(dev, sglist, nents, direction); - -as appropriate. - -After the last DMA transfer call one of the DMA unmap routines -pci_unmap_{single,sg}. If you don't touch the data from the first pci_map_* -call till pci_unmap_*, then you don't have to call the pci_dma_sync_* -routines at all. - -Here is pseudo code which shows a situation in which you would need -to use the pci_dma_sync_*() interfaces. - - my_card_setup_receive_buffer(struct my_card *cp, char *buffer, int len) - { - dma_addr_t mapping; - - mapping = pci_map_single(cp->pdev, buffer, len, PCI_DMA_FROMDEVICE); - - cp->rx_buf = buffer; - cp->rx_len = len; - cp->rx_dma = mapping; - - give_rx_buf_to_card(cp); - } - - ... - - my_card_interrupt_handler(int irq, void *devid, struct pt_regs *regs) - { - struct my_card *cp = devid; - - ... - if (read_card_status(cp) == RX_BUF_TRANSFERRED) { - struct my_card_header *hp; - - /* Examine the header to see if we wish - * to accept the data.

Miller + Richard Henderson + Jakub Jelinek + +This document describes the DMA mapping system in terms of the pci_ +API. For a similar API that works for generic devices, see +DMA-API.txt. + +Most of the 64bit platforms have special hardware that translates bus +addresses (DMA addresses) into physical addresses. This is similar to +how page tables and/or a TLB translates virtual addresses to physical +addresses on a CPU. This is needed so that e.g. PCI devices can +access with a Single Address Cycle (32bit DMA address) any page in the +64bit physical address space. Previously in Linux those 64bit +platforms had to set artificial limits on the maximum RAM size in the +system, so that the virt_to_bus() static scheme works (the DMA address +translation tables were simply filled on bootup to map each bus +address to the physical page __pa(bus_to_virt())). + +So that Linux can use the dynamic DMA mapping, it needs some help from the +drivers, namely it has to take into account that DMA addresses should be +mapped only for the time they are actually used and unmapped after the DMA +transfer. + +The following API will work of course even on platforms where no such +hardware exists, see e.g. arch/x86/include/asm/pci.h for how it is implemented on +top of the virt_to_bus interface. + +First of all, you should make sure + +#include + +is in your driver. This file will obtain for you the definition of the +dma_addr_t (which can hold any valid DMA address for the platform) +type which should be used everywhere you hold a DMA (bus) address +returned from the DMA mapping functions. + + What memory is DMA'able? + +The first piece of information you must know is what kernel memory can +be used with the DMA mapping facilities. There has been an unwritten +set of rules regarding this, and this text is an attempt to finally +write them down. + +If you acquired your memory via the page allocator +(i.e. __get_free_page*()) or the generic memory allocators +(i.e. kmalloc() or kmem_cache_alloc()) then you may DMA to/from +that memory using the addresses returned from those routines. + +This means specifically that you may _not_ use the memory/addresses +returned from vmalloc() for DMA. It is possible to DMA to the +_underlying_ memory mapped into a vmalloc() area, but this requires +walking page tables to get the physical addresses, and then +translating each of those pages back to a kernel address using +something like __va(). [ EDIT: Update this when we integrate +Gerd Knorr's generic code which does this. ] + +This rule also means that you may use neither kernel image addresses +(items in data/text/bss segments), nor module image addresses, nor +stack addresses for DMA. These could all be mapped somewhere entirely +different than the rest of physical memory. Even if those classes of +memory could physically work with DMA, you'd need to ensure the I/O +buffers were cacheline-aligned. Without that, you'd see cacheline +sharing problems (data corruption) on CPUs with DMA-incoherent caches. +(The CPU could write to one word, DMA would write to a different one +in the same cache line, and one of them could be overwritten.) + +Also, this means that you cannot take the return of a kmap() +call and DMA to/from that. This is similar to vmalloc(). + +What about block I/O and networking buffers? The block I/O and +networking subsystems make sure that the buffers they use are valid +for you to DMA from/to. + + DMA addressing limitations + +Does your device have any DMA addressing limitations? For example, is +your device only capable of driving the low order 24-bits of address +on the PCI bus for SAC DMA transfers? If so, you need to inform the +PCI layer of this fact. + +By default, the kernel assumes that your device can address the full +32-bits in a SAC cycle. For a 64-bit DAC capable device, this needs +to be increased. And for a device with limitations, as discussed in +the previous paragraph, it needs to be decreased. + +pci_alloc_consistent() by default will return 32-bit DMA addresses. +PCI-X specification requires PCI-X devices to support 64-bit +addressing (DAC) for all transactions. And at least one platform (SGI +SN2) requires 64-bit consistent allocations to operate correctly when +the IO bus is in PCI-X mode. Therefore, like with pci_set_dma_mask(), +it's good practice to call pci_set_consistent_dma_mask() to set the +appropriate mask even if your device only supports 32-bit DMA +(default) and especially if it's a PCI-X device. + +For correct operation, you must interrogate the PCI layer in your +device probe routine to see if the PCI controller on the machine can +properly support the DMA addressing limitation your device has. It is +good style to do this even if your device holds the default setting, +because this shows that you did think about these issues wrt. your +device. + +The query is performed via a call to pci_set_dma_mask(): + + int pci_set_dma_mask(struct pci_dev *pdev, u64 device_mask); + +The query for consistent allocations is performed via a call to +pci_set_consistent_dma_mask(): + + int pci_set_consistent_dma_mask(struct pci_dev *pdev, u64 device_mask); + +Here, pdev is a pointer to the PCI device struct of your device, and +device_mask is a bit mask describing which bits of a PCI address your +device supports. It returns zero if your card can perform DMA +properly on the machine given the address mask you provided. + +If it returns non-zero, your device cannot perform DMA properly on +this platform, and attempting to do so will result in undefined +behavior. You must either use a different mask, or not use DMA. + +This means that in the failure case, you have three options: + +1) Use another DMA mask, if possible (see below). +2) Use some non-DMA mode for data transfer, if possible. +3) Ignore this device and do not initialize it. + +It is recommended that your driver print a kernel KERN_WARNING message +when you end up performing either #2 or #3. In this manner, if a user +of your driver reports that performance is bad or that the device is not +even detected, you can ask them for the kernel messages to find out +exactly why. + +The standard 32-bit addressing PCI device would do something like +this: + + if (pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) { + printk(KERN_WARNING + "mydev: No suitable DMA available.\n"); + goto ignore_this_device; + } + +Another common scenario is a 64-bit capable device. The approach +here is to try for 64-bit DAC addressing, but back down to a +32-bit mask should that fail. The PCI platform code may fail the +64-bit mask not because the platform is not capable of 64-bit +addressing. Rather, it may fail in this case simply because +32-bit SAC addressing is done more efficiently than DAC addressing. +Sparc64 is one platform which behaves in this way. + +Here is how you would handle a 64-bit capable device which can drive +all 64-bits when accessing streaming DMA: + + int using_dac; + + if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(64))) { + using_dac = 1; + } else if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) { + using_dac = 0; + } else { + printk(KERN_WARNING + "mydev: No suitable DMA available.\n"); + goto ignore_this_device; + } + +If a card is capable of using 64-bit consistent allocations as well, +the case would look like this: + + int using_dac, consistent_using_dac; + + if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(64))) { + using_dac = 1; + consistent_using_dac = 1; + pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(64)); + } else if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) { + using_dac = 0; + consistent_using_dac = 0; + pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(32)); + } else { + printk(KERN_WARNING + "mydev: No suitable DMA available.\n"); + goto ignore_this_device; + } + +pci_set_consistent_dma_mask() will always be able to set the same or a +smaller mask as pci_set_dma_mask(). However for the rare case that a +device driver only uses consistent allocations, one would have to +check the return value from pci_set_consistent_dma_mask(). + +Finally, if your device can only drive the low 24-bits of +address during PCI bus mastering you might do something like: + + if (pci_set_dma_mask(pdev, DMA_BIT_MASK(24))) { + printk(KERN_WARNING + "mydev: 24-bit DMA addressing not available.\n"); + goto ignore_this_device; + } + +When pci_set_dma_mask() is successful, and returns zero, the PCI layer +saves away this mask you have provided. The PCI layer will use this +information later when you make DMA mappings. + +There is a case which we are aware of at this time, which is worth +mentioning in this documentation. If your device supports multiple +functions (for example a sound card provides playback and record +functions) and the various different functions have _different_ +DMA addressing limitations, you may wish to probe each mask and +only provide the functionality which the machine can handle. It +is important that the last call to pci_set_dma_mask() be for the +most specific mask. + +Here is pseudo-code showing how this might be done: + + #define PLAYBACK_ADDRESS_BITS DMA_BIT_MASK(32) + #define RECORD_ADDRESS_BITS DMA_BIT_MASK(24) + + struct my_sound_card *card; + struct pci_dev *pdev; + + ... + if (!pci_set_dma_mask(pdev, PLAYBACK_ADDRESS_BITS)) { + card->playback_enabled = 1; + } else { + card->playback_enabled = 0; + printk(KERN_WARNING "%s: Playback disabled due to DMA limitations.\n", + card->name); + } + if (!pci_set_dma_mask(pdev, RECORD_ADDRESS_BITS)) { + card->record_enabled = 1; + } else { + card->record_enabled = 0; + printk(KERN_WARNING "%s: Record disabled due to DMA limitations.\n", + card->name); + } + +A sound card was used as an example here because this genre of PCI +devices seems to be littered with ISA chips given a PCI front end, +and thus retaining the 16MB DMA addressing limitations of ISA. + + Types of DMA mappings + +There are two types of DMA mappings: + +- Consistent DMA mappings which are usually mapped at driver + initialization, unmapped at the end and for which the hardware should + guarantee that the device and the CPU can access the data + in parallel and will see updates made by each other without any + explicit software flushing. + + Think of "consistent" as "synchronous" or "coherent". + + The current default is to return consistent memory in the low 32 + bits of the PCI bus space. However, for future compatibility you + should set the consistent mask even if this default is fine for your + driver. + + Good examples of what to use consistent mappings for are: + + - Network card DMA ring descriptors. + - SCSI adapter mailbox command data structures. + - Device firmware microcode executed out of + main memory. + + The invariant these examples all require is that any CPU store + to memory is immediately visible to the device, and vice + versa. Consistent mappings guarantee this. + + IMPORTANT: Consistent DMA memory does not preclude the usage of + proper memory barriers. The CPU may reorder stores to + consistent memory just as it may normal memory. Example: + if it is important for the device to see the first word + of a descriptor updated before the second, you must do + something like: + + desc->word0 = address; + wmb(); + desc->word1 = DESC_VALID; + + in order to get correct behavior on all platforms. + + Also, on some platforms your driver may need to flush CPU write + buffers in much the same way as it needs to flush write buffers + found in PCI bridges (such as by reading a register's value + after writing it). + +- Streaming DMA mappings which are usually mapped for one DMA transfer, + unmapped right after it (unless you use pci_dma_sync_* below) and for which + hardware can optimize for sequential accesses. + + This of "streaming" as "asynchronous" or "outside the coherency + domain". + + Good examples of what to use streaming mappings for are: + + - Networking buffers transmitted/received by a device. + - Filesystem buffers written/read by a SCSI device. + + The interfaces for using this type of mapping were designed in + such a way that an implementation can make whatever performance + optimizations the hardware allows. To this end, when using + such mappings you must be explicit about what you want to happen. + +Neither type of DMA mapping has alignment restrictions that come +from PCI, although some devices may have such restrictions. +Also, systems with caches that aren't DMA-coherent will work better +when the underlying buffers don't share cache lines with other data. + + + Using Consistent DMA mappings. + +To allocate and map large (PAGE_SIZE or so) consistent DMA regions, +you should do: + + dma_addr_t dma_handle; + + cpu_addr = pci_alloc_consistent(pdev, size, &dma_handle); + +where pdev is a struct pci_dev *. This may be called in interrupt context. +You should use dma_alloc_coherent (see DMA-API.txt) for buses +where devices don't have struct pci_dev (like ISA, EISA). + +This argument is needed because the DMA translations may be bus +specific (and often is private to the bus which the device is attached +to). + +Size is the length of the region you want to allocate, in bytes. + +This routine will allocate RAM for that region, so it acts similarly to +__get_free_pages (but takes size instead of a page order). If your +driver needs regions sized smaller than a page, you may prefer using +the pci_pool interface, described below. + +The consistent DMA mapping interfaces, for non-NULL pdev, will by +default return a DMA address which is SAC (Single Address Cycle) +addressable. Even if the device indicates (via PCI dma mask) that it +may address the upper 32-bits and thus perform DAC cycles, consistent +allocation will only return > 32-bit PCI addresses for DMA if the +consistent dma mask has been explicitly changed via +pci_set_consistent_dma_mask(). This is true of the pci_pool interface +as well. + +pci_alloc_consistent returns two values: the virtual address which you +can use to access it from the CPU and dma_handle which you pass to the +card. + +The cpu return address and the DMA bus master address are both +guaranteed to be aligned to the smallest PAGE_SIZE order which +is greater than or equal to the requested size. This invariant +exists (for example) to guarantee that if you allocate a chunk +which is smaller than or equal to 64 kilobytes, the extent of the +buffer you receive will not cross a 64K boundary. + +To unmap and free such a DMA region, you call: + + pci_free_consistent(pdev, size, cpu_addr, dma_handle); + +where pdev, size are the same as in the above call and cpu_addr and +dma_handle are the values pci_alloc_consistent returned to you. +This function may not be called in interrupt context. + +If your driver needs lots of smaller memory regions, you can write +custom code to subdivide pages returned by pci_alloc_consistent, +or you can use the pci_pool API to do that. A pci_pool is like +a kmem_cache, but it uses pci_alloc_consistent not __get_free_pages. +Also, it understands common hardware constraints for alignment, +like queue heads needing to be aligned on N byte boundaries. + +Create a pci_pool like this: + + struct pci_pool *pool; + + pool = pci_pool_create(name, pdev, size, align, alloc); + +The "name" is for diagnostics (like a kmem_cache name); pdev and size +are as above. The device's hardware alignment requirement for this +type of data is "align" (which is expressed in bytes, and must be a +power of two). If your device has no boundary crossing restrictions, +pass 0 for alloc; passing 4096 says memory allocated from this pool +must not cross 4KByte boundaries (but at that time it may be better to +go for pci_alloc_consistent directly instead). + +Allocate memory from a pci pool like this: + + cpu_addr = pci_pool_alloc(pool, flags, &dma_handle); + +flags are SLAB_KERNEL if blocking is permitted (not in_interrupt nor +holding SMP locks), SLAB_ATOMIC otherwise. Like pci_alloc_consistent, +this returns two values, cpu_addr and dma_handle. + +Free memory that was allocated from a pci_pool like this: + + pci_pool_free(pool, cpu_addr, dma_handle); + +where pool is what you passed to pci_pool_alloc, and cpu_addr and +dma_handle are the values pci_pool_alloc returned. This function +may be called in interrupt context. + +Destroy a pci_pool by calling: + + pci_pool_destroy(pool); + +Make sure you've called pci_pool_free for all memory allocated +from a pool before you destroy the pool. This function may not +be called in interrupt context. + + DMA Direction + +The interfaces described in subsequent portions of this document +take a DMA direction argument, which is an integer and takes on +one of the following values: + + PCI_DMA_BIDIRECTIONAL + PCI_DMA_TODEVICE + PCI_DMA_FROMDEVICE + PCI_DMA_NONE + +One should provide the exact DMA direction if you know it. + +PCI_DMA_TODEVICE means "from main memory to the PCI device" +PCI_DMA_FROMDEVICE means "from the PCI device to main memory" +It is the direction in which the data moves during the DMA +transfer. + +You are _strongly_ encouraged to specify this as precisely +as you possibly can. + +If you absolutely cannot know the direction of the DMA transfer, +specify PCI_DMA_BIDIRECTIONAL. It means that the DMA can go in +either direction. The platform guarantees that you may legally +specify this, and that it will work, but this may be at the +cost of performance for example. + +The value PCI_DMA_NONE is to be used for debugging. One can +hold this in a data structure before you come to know the +precise direction, and this will help catch cases where your +direction tracking logic has failed to set things up properly. + +Another advantage of specifying this value precisely (outside of +potential platform-specific optimizations of such) is for debugging. +Some platforms actually have a write permission boolean which DMA +mappings can be marked with, much like page protections in the user +program address space. Such platforms can and do report errors in the +kernel logs when the PCI controller hardware detects violation of the +permission setting. + +Only streaming mappings specify a direction, consistent mappings +implicitly have a direction attribute setting of +PCI_DMA_BIDIRECTIONAL. + +The SCSI subsystem tells you the direction to use in the +'sc_data_direction' member of the SCSI command your driver is +working on. + +For Networking drivers, it's a rather simple affair. For transmit +packets, map/unmap them with the PCI_DMA_TODEVICE direction +specifier. For receive packets, just the opposite, map/unmap them +with the PCI_DMA_FROMDEVICE direction specifier. + + Using Streaming DMA mappings + +The streaming DMA mapping routines can be called from interrupt +context. There are two versions of each map/unmap, one which will +map/unmap a single memory region, and one which will map/unmap a +scatterlist. + +To map a single region, you do: + + struct pci_dev *pdev = mydev->pdev; + dma_addr_t dma_handle; + void *addr = buffer->ptr; + size_t size = buffer->len; + + dma_handle = pci_map_single(pdev, addr, size, direction); + +and to unmap it: + + pci_unmap_single(pdev, dma_handle, size, direction); + +You should call pci_unmap_single when the DMA activity is finished, e.g. +from the interrupt which told you that the DMA transfer is done. + +Using cpu pointers like this for single mappings has a disadvantage, +you cannot reference HIGHMEM memory in this way. Thus, there is a +map/unmap interface pair akin to pci_{map,unmap}_single. These +interfaces deal with page/offset pairs instead of cpu pointers. +Specifically: + + struct pci_dev *pdev = mydev->pdev; + dma_addr_t dma_handle; + struct page *page = buffer->page; + unsigned long offset = buffer->offset; + size_t size = buffer->len; + + dma_handle = pci_map_page(pdev, page, offset, size, direction); + + ... + + pci_unmap_page(pdev, dma_handle, size, direction); + +Here, "offset" means byte offset within the given page. + +With scatterlists, you map a region gathered from several regions by: + + int i, count = pci_map_sg(pdev, sglist, nents, direction); + struct scatterlist *sg; + + for_each_sg(sglist, sg, count, i) { + hw_address[i] = sg_dma_address(sg); + hw_len[i] = sg_dma_len(sg); + } + +where nents is the number of entries in the sglist. + +The implementation is free to merge several consecutive sglist entries +into one (e.g. if DMA mapping is done with PAGE_SIZE granularity, any +consecutive sglist entries can be merged into one provided the first one +ends and the second one starts on a page boundary - in fact this is a huge +advantage for cards which either cannot do scatter-gather or have very +limited number of scatter-gather entries) and returns the actual number +of sg entries it mapped them to. On failure 0 is returned. + +Then you should loop count times (note: this can be less than nents times) +and use sg_dma_address() and sg_dma_len() macros where you previously +accessed sg->address and sg->length as shown above. + +To unmap a scatterlist, just call: + + pci_unmap_sg(pdev, sglist, nents, direction); + +Again, make sure DMA activity has already finished. + +PLEASE NOTE: The 'nents' argument to the pci_unmap_sg call must be + the _same_ one you passed into the pci_map_sg call, + it should _NOT_ be the 'count' value _returned_ from the + pci_map_sg call. + +Every pci_map_{single,sg} call should have its pci_unmap_{single,sg} +counterpart, because the bus address space is a shared resource (although +in some ports the mapping is per each BUS so less devices contend for the +same bus address space) and you could render the machine unusable by eating +all bus addresses. + +If you need to use the same streaming DMA region multiple times and touch +the data in between the DMA transfers, the buffer needs to be synced +properly in order for the cpu and device to see the most uptodate and +correct copy of the DMA buffer. + +So, firstly, just map it with pci_map_{single,sg}, and after each DMA +transfer call either: + + pci_dma_sync_single_for_cpu(pdev, dma_handle, size, direction); + +or: + + pci_dma_sync_sg_for_cpu(pdev, sglist, nents, direction); + +as appropriate. + +Then, if you wish to let the device get at the DMA area again, +finish accessing the data with the cpu, and then before actually +giving the buffer to the hardware call either: + + pci_dma_sync_single_for_device(pdev, dma_handle, size, direction); + +or: + + pci_dma_sync_sg_for_device(dev, sglist, nents, direction); + +as appropriate. + +After the last DMA transfer call one of the DMA unmap routines +pci_unmap_{single,sg}. If you don't touch the data from the first pci_map_* +call till pci_unmap_*, then you don't have to call the pci_dma_sync_* +routines at all. + +Here is pseudo code which shows a situation in which you would need +to use the pci_dma_sync_*() interfaces. + + my_card_setup_receive_buffer(struct my_card *cp, char *buffer, int len) + { + dma_addr_t mapping; + + mapping = pci_map_single(cp->pdev, buffer, len, PCI_DMA_FROMDEVICE); + + cp->rx_buf = buffer; + cp->rx_len = len; + cp->rx_dma = mapping; + + give_rx_buf_to_card(cp); + } + + ... + + my_card_interrupt_handler(int irq, void *devid, struct pt_regs *regs) + { + struct my_card *cp = devid; + + ... + if (read_card_status(cp) == RX_BUF_TRANSFERRED) { + struct my_card_header *hp; + + /* Examine the header to see if we wish + * to accept the data.

Some drivers have to be changed a +little bit, because there is no longer an equivalent to bus_to_virt in the +dynamic DMA mapping scheme - you have to always store the DMA addresses +returned by the pci_alloc_consistent, pci_pool_alloc, and pci_map_single +calls (pci_map_sg stores them in the scatterlist itself if the platform +supports dynamic DMA mapping in hardware) in your driver structures and/or +in the card registers. + +All PCI drivers should be using these interfaces with no exceptions. +It is planned to completely remove virt_to_bus() and bus_to_virt() as +they are entirely deprecated. Some ports already do not provide these +as it is impossible to correctly support them. + + Optimizing Unmap State Space Consumption + +On many platforms, pci_unmap_{single,page}() is simply a nop. +Therefore, keeping track of the mapping address and length is a waste +of space. Instead of filling your drivers up with ifdefs and the like +to "work around" this (which would defeat the whole purpose of a +portable API) the following facilities are provided. + +Actually, instead of describing the macros one by one, we'll +transform some example code. + +1) Use DECLARE_PCI_UNMAP_{ADDR,LEN} in state saving structures. + Example, before: + + struct ring_state { + struct sk_buff *skb; + dma_addr_t mapping; + __u32 len; + }; + + after: + + struct ring_state { + struct sk_buff *skb; + DECLARE_PCI_UNMAP_ADDR(mapping) + DECLARE_PCI_UNMAP_LEN(len) + }; + + NOTE: DO NOT put a semicolon at the end of the DECLARE_*() + macro. + +2) Use pci_unmap_{addr,len}_set to set these values. + Example, before: + + ringp->mapping = FOO; + ringp->len = BAR; + + after: + + pci_unmap_addr_set(ringp, mapping, FOO); + pci_unmap_len_set(ringp, len, BAR); + +3) Use pci_unmap_{addr,len} to access these values. + Example, before: + + pci_unmap_single(pdev, ringp->mapping, ringp->len, + PCI_DMA_FROMDEVICE); + + after: + + pci_unmap_single(pdev, + pci_unmap_addr(ringp, mapping), + pci_unmap_len(ringp, len), + PCI_DMA_FROMDEVICE); + +It really should be self-explanatory. We treat the ADDR and LEN +separately, because it is possible for an implementation to only +need the address in order to perform the unmap operation. + + Platform Issues + +If you are just writing drivers for Linux and do not maintain +an architecture port for the kernel, you can safely skip down +to "Closing". + +1) Struct scatterlist requirements. + + Struct scatterlist must contain, at a minimum, the following + members: + + struct page *page; + unsigned int offset; + unsigned int length; + + The base address is specified by a "page+offset" pair. + + Previous versions of struct scatterlist contained a "void *address" + field that was sometimes used instead of page+offset.

Unfortunately, the ipvs code forgot to check if the cmd was in the range that the array provides, allowing for an index outside of the array, which then gives a "garbage" result into the length, which then gets used for copying into a stack buffer.

Normally it's possible (but not required) that the firmware has the knowledge that it is an invalid lun.

The I model s_active count + completion as a sleeping read/write lock. I describe to lockdep sysfs_get_active as a read_trylock, sysfs_put_active as a read_unlock, and sysfs_deactivate as a write_lock and write_unlock pair. This seems to capture the essence for purposes of finding deadlocks, and in my testing gives finds real issues and ignores non-issues. This brings us back to holding locks over kobject_del is a problem that ideally we should find a way of addressing, but at least lockdep can tell us about the problems instead of requiring developers to debug rare strange system deadlocks, that happen when sysfs files are removed while being written to.

Wysocki" Date: Thu, 31 Dec 2009 12:15:54 +0100 Subject: PCI/PM: Use per-device D3 delays It turns out that some PCI devices require extra delays when changing power state from D3 to D0 (and the other way around). Although this is against the PCI specification, we can handle it quite easily by allowing drivers to define arbitrary D3 delays for devices known to require extra time for switching power states. Introduce additional field d3_delay in struct pci_dev and use it to store the value of the device's D0->D3 delay, in miliseconds. Make the PCI PM core code use the per-device d3_delay unless pci_pm_d3_delay is greater (in which case the latter is used). [This also allows the driver to specify d3_delay shorter than the 10 ms required by the PCI standard if the device is known to be able to handle that.] Make the sky2 driver set d3_delay to 150 for devices handled by it.

Since we needed these types before the pnfs-objects code was accepted to mainline we duplicated the minimal needed definitions into an exofs local header. The definitions where conditionally included depending on !CONFIG_PNFS defined. So if PNFS was present in the tree definitions are taken from there and if not they are defined locally. That was all good but, the CONFIG_PNFS is planed to be included upstream before the pnfs-objects is also included. (The first pnfs batch might be pnfs-files only) So condition exofs local definitions on the absence of pnfs_osd_xdr.h inclusion (__PNFS_OSD_XDR_H__ not defined). User code must make sure that in future pnfs_osd_xdr.h will be included before fs/exofs/pnfs.h, which happens to be so in current code. Once pnfs-objects hits mainline, exofs's local header will be removed.

But it is not enough because simple_write_end() does not call mark_inode_dirty() when it extends i_size. So even if we do call mark_inode_dirty at beginning of write out, with a very long IO and a saturated system we might get the .write_inode() called while still extend-writing to file and miss out on the last i_size updates. So override .write_end, call simple_write_end(), and afterwords if i_size was changed call mark_inode_dirty(). It stands to logic that since simple_write_end() was the one extending i_size it should also call mark_inode_dirty(). But it looks like all users of simple_write_end() are memory-bound pseudo filesystems, who could careless about mark_inode_dirty(). I might submit a warning-comment patch to simple_write_end() in future.

Compatibility with the existing execbuf ioctl is implemented in terms of the new code, preserving the assumption that fence registers are required for pre-965 rendering commands.

Instead, use the G4X DPLL calculator, which does a better job at it. So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS on ironlake. At the same time to consider the dpll setting for display port, we add the display port DPLL limit on ironlake, which will directly use the function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.

With this change, we can run into a situation where an irq cleanup interrupt on a cpu can cleanup the vector mappings associated with multiple irqs, of which one of the irq's migration might be still in progress. As such when that irq hits the old cpu, we get the "No IRQ handler" messages. Fix this by checking for the irq_cfg's move_in_progress and if the move is still in progress delay the vector cleanup to another irq cleanup interrupt request (which will happen when the irq starts arriving at the new cpu destination).

The NOMMU code path always passes PROT_EXEC to the mmap() call. While this doesn't matter to most people whilst the code is running, it will cause a pointless icache flush when starting every FDPIC application. Typically this icache flush will be of a region on the order of 128KB in size, or may be the entire icache, depending on the facilities available on the CPU. In the case where the arch default behaviour seems to be desired (EXSTACK_DEFAULT), we probe VM_STACK_FLAGS for VM_EXEC to determine whether we should be setting PROT_EXEC or not. For arches that support an MPU (Memory Protection Unit - an MMU without the virtual mapping capability), setting PROT_EXEC or not will make an important difference. It should be noted that this change also affects the executability of the brk region, since ELF-FDPIC has that share with the stack. However, this is probably irrelevant as NOMMU programs aren't likely to use the brk region, preferring instead allocation via mmap().

The flush can instead be done when a region is first mmapped PROT_EXEC. Note that we may not rely on the first mapping of a region being executable - it's possible for it to be PROT_READ only, so we have to remember whether we've flushed the region or not, and then flush the entire region when a bit of it is made executable. However, this also affects the brk area. That will no longer be executable. We can mprotect() it to PROT_EXEC on MPU-mode kernels, but for NOMMU mode kernels, when it increases the brk allocation, making sys_brk() flush the extra from the icache should suffice. The brk area probably isn't used by NOMMU programs since the brk area can only use up the leavings from the stack allocation, where the stack allocation is larger than requested.

This is important when doing things like setting software breakpoints with gdb. So switch the NOMMU code over to do the same. This patch makes the reasonable assumption that copy_from_user_page() won't fail - which is probably fine, as we've checked the VMA from which we're copying is usable, and the copy is not allowed to cross VMAs. The one case where it might go wrong is if the VMA is a device rather than RAM, and that device returns an error which - in which case rubbish will be returned rather than EIO.

Anything using clk_mpll directly really should not be relying on this being the clock that is eventually routed to a peripheral, so remove the loop and ensure that the clocks accurately represent the clock chain in the device.

The mc_loop flag is present in the family specific part of the socket (e.g. the IPv4 or IPv4 specific part). setsockopt sets the inner family mc_loop flag. When the packet is pushed through the L3 tunnel it will eventually be processed by the outer family which if different will check the flag in a different part of the socket then it was set.

These extra bytes are skb_reserve()'d before DMA mapping, so they should not be included in the DMA map byte count (as the mapping is done starting at skb->data), nor should they be included in the receive descriptor buffer size field, or the hardware can end up DMAing beyond the end of the buffer, which can happen if someone sends us a larger-than-MTU sized packet. This problem was introduced in commit 7fd96ce47ff ("mv643xx_eth: rework receive skb cache alignment", May 6 2009), but hasn't appeared to be problematic so far, probably as the main users of mv643xx_eth all have NET_SKB_PAD == L1_CACHE_BYTES.

In order to get the expected result from O_APPEND opens, this patch updated the inode size before calling generic_file_aio_write() There is of course still a race here, in that there is nothing to prevent another node coming in and extending the file in the mean time. On the other hand, when used with file locking this will ensure that the expected results are obtained.

Additionally, current code forces rising edge detection if both flags are specified: if (trigger & IRQ_TYPE_EDGE_RISING) l |= 1 << gpio; else if (trigger & IRQ_TYPE_EDGE_FALLING) l &= ~(1 << gpio); else goto bad; This change implements a toggle function that will modify the ICR to flip the direction of interrupt for IRQs that are requested with both rising and falling flags. The toggle function is not called for chips and GPIOs it does not apply to through the use of a flip_mask that's added on a per-bank basis. The mask is only set for those GPIOs where a toggle is necessary. Edge detection starts out the same as above with FALLING mode first. The toggle happens on EACH interrupt; without it, we have the following sequence of actions on GPIO transition: ICR GPIO Result 0x1 0 -> 1 (rising) Interrupt 0x1 1 -> 0 (falling) No interrupt (set ICR to 0x0 manually) 0x0 0 -> 1 (rising) No interrupt 0x0 1 -> 0 (falling) Interrupt That is, with the ICR set to 1 for a gpio, only rising edge interrupts are caught, and with it set to 0, only falling edge interrupts are caught. If we add in the toggle, we get this: ICR GPIO Result 0x1 0 -> 1 (rising) Interrupt (ICR set to 0x0) 0x0 1 -> 0 (falling) Interrupt (ICR set to 0x1) 0x1 0 -> 1 ... so, both rising and falling are caught, per the request for both (IRQ_TYPE_EDGE_RISING | IRQ_TYPE_EDGE_FALLING).

This patch makes sure we update it in a consistent way: - always transactional - ctime is only updated if ATTR_CTIME is set or we do a size update, which is a special case - always to the times passed in from the caller instead of the current time The only non-size caller of xfs_setattr that doesn't come from the VFS is updated to set ATTR_CTIME and pass in a valid ctime value.

The current implementation has a subtle bug in it--it does not handle multiple overlapping ranges. That is, if we free lots of little extents into a single contiguous extent, then allocate the contiguous extent, the busy search code stops searching at the first extent it finds that overlaps the allocated range. It then uses the commit LSN of the transaction to force the log out to. Unfortunately, the other busy ranges might have more recent commit LSNs than the first busy extent that is found, and this results in xfs_alloc_search_busy() returning before all the extent free transactions are on disk for the range being allocated. This can lead to potential metadata corruption or stale data exposure after a crash because log replay won't replay all the extent free transactions that cover the allocation range.

NVIDIA? :P It appears it's possible for a ctxprog to run even while a GPU exception is pending. The GF8 and up ctxprogs appear to have a small snippet of code which detects this, and stalls the ctxprog until it's been handled, which essentially looks like: if (r2 & 0x00008000) { r0 |= 0x80000000; while (r0 & 0x80000000) {} } I don't know of any way that flag would get cleared unless the driver intervenes (and indeed, in the cases I've seen the hang, nothing steps in to automagically clear it for us). This patch causes the driver to clear the flag during the PGRAPH IRQ handler.

While doing so, it destroys the operation fence, causing nouveau_fence_emit to crash. This patch fixes this bug by taking the fence object out of validate_op and creating it just before emit. The fence pointer is initialized to 0 and unref'ed unconditionally. In addition to fixing the bug, this prevents its reintroduction and simplifies the code.

When call_usermodehelper_exec() fails, write-pipe file is opened and call_usermodehelper_pipe() just returns an error. Since it is hard for caller to determine whether the error occured when opening the pipe or executing the helper, the caller cannot close the pipe by themselves.

The copy loop just above this one can also use this optimization, but I havn't done so as I have not tested if it is a win there too.

Russell King said: : Testing on a Cortex A9 model: : - lzo decompressor is 65% of the time gzip takes to decompress a kernel : - lzo kernel is 9% larger than a gzip kernel : : which I'm happy to say confirms your figures when comparing the two. : : However, when comparing your new gzip code to the old gzip code: : - new is 99% of the size of the old code : - new takes 42% of the time to decompress than the old code : : What this means is that for a proper comparison, the results get even better: : - lzo is 7.5% larger than the old gzip'd kernel image : - lzo takes 28% of the time that the old gzip code took : : So the expense seems definitely worth the effort. The only reason I : can think of ever using gzip would be if you needed the additional : compression (eg, because you have limited flash to store the image.) : : I would argue that the default for ARM should therefore be LZO. This patch: The lzo compressor is worse than gzip at compression, but faster at extraction. Here are some figures for an ARM board I'm working on: Uncompressed size: 3.24Mo gzip 1.61Mo 0.72s lzo 1.75Mo 0.48s So for a compression ratio that is still relatively close to gzip, it's much faster to extract, at least in that case. This part contains: - Makefile routine to support lzo compression - Fixes to the existing lzo compressor so that it can be used in compressed kernels - wrapper around the existing lzo1x_decompress, as it only extracts one block at a time, while we need to extract a whole file here - config dialog for kernel compression [akpm@linux-foundation.org: coding-style fixes] [akpm@linux-foundation.org: cleanup] Signed-off-by: Albin Tonnerre Tested-by: Wu Zhangjin Acked-by: "H.

(2) if no matching cgroup_pidlist is found, then a new one is allocated, it down_write's its mutex, and the use_count is set to 0. (3) the matching, or new, cgroup_pidlist gets returned back to pidlist_array_load(), which increments its use_count -- regardless whether new or pre-existing -- and up_write's the mutex. So if a matching list is ever encountered by cgroup_pidlist_find() during the life of a cgroup directory, it results in an inflated use_count value, preventing it from ever getting released by cgroup_release_pid_array(). Then if the directory is subsequently removed, cgroup_diput() hits the BUG_ON() when it finds that the directory's cgroup is still populated with a pidlist. The patch simply removes the use_count increment when a matching pidlist is found by cgroup_pidlist_find(), because it gets bumped by the calling pidlist_array_load() function while still protected by the list's mutex.

Or crash the system if there's some hardware with read side effects. The fatal signals handler will dump 16 bytes at the execution address, which is fully controlled by ring 3. In addition when something jumps to a unmapped address there will be up to 16 additional useless page faults, which might be potentially slow (and at least is not very efficient) Fortunately this option is off by default and only there on i386. But fix it by checking for kernel addresses and also stopping when there's a page fault.

When new threads are cloned with CLONE_VM, they don't inherit the alternate signal stack. They do share the signal flags, though. When deciding whether to use an alternate stack, the arch code needs to check to make sure the task struct contains a valid alternate stack. This patch fixes the MN10300 arch by using the sas_ss_flags() test provided by sched.h rather than the on_sig_stack() test which is insufficient by itself.

This is required because the CPU's window onto the PCI bus address space is considerably smaller than the CPU's full address space and non-PCI devices lie outside of the PCI window that we might want to access. Without this patch, the PCI root bus uses the platform-level bus resources, and these are then confined to the PCI window, thus making platform_device_add() reject devices outside of this window. We also add a reservation for the PCI SRAM region.

This is almost certainly due to a bug in the PCI bridge FPGA on that board. We can get around this by making dma_alloc_coherent() put the ring buffer in the SRAM attached to the PCI bridge rather than in the SDRAM.

Unfortunately userspace can arrange for those pointers to actually be dereferencable, potentially turning an oops to an expolit. To avoid this allow architectures (currently x86_64 only) to override the default values for these pointers with truly-undereferencable values. This is easy on x86_64 as the virtual address space is large and contains areas that cannot be mapped. Other 64-bit architectures will likely find similar unmapped ranges.

According to Suresh, this might be an IBM platform issue, as on other Intel platforms with <= 8 logical cpu's, logical flat mode works fine irespective of physical apic id values (inline with the xapic architecture).

Since over/under-runs were thought to be rare and transient, this action seemed reasonable. Unfortunately it turns out that the controller throws overrun errors when e.g. hal polls a CD or DVD writer containing blank media, causing long sequences of hard resets and retries before EH finally gives up. This patch updates sata_promise to classify over/under-runs as AC_ERR_OTHER instead. This allows libata EH and upper layers to retry or fail the operation as they see fit without the disruption caused by repeated hard resets. This fixes a problem using a DVD-RAM drive with sata_promise, reported by Thomas Schorpp. I also tested it on a DVD-RW drive.
