| | | | | | | | | | | | | | | | Remove redundant DMA_..BIT_MASK definitions across two drivers. The computation of the majority of the bitmasks is done by the compiler. The initial split of the patch touching each a different file got removed due to possible git bisect breakage.

* Fix discrepancy between VDSO based gettimeofday() and sys_gettimeofday().Tony Breeds2007-10-181-0/+5
| | | | | | | | | | | | | | | | | | | | On platforms that copy sys_tz into the vdso (currently only x86_64, soon to include powerpc), it is possible for the vdso to get out of sync if a user calls (admittedly unusual) settimeofday(NULL, ptr). This patch adds a hook for architectures that set CONFIG_GENERIC_TIME_VSYSCALL to ensure when sys_tz is updated they can also updatee their copy in the vdso.

* Hibernation: Check if ACPI is enabled during restore in the right placeRafael J. Wysocki2007-10-181-0/+7
| | | | | | | | | | | | | | | | | | | | | | | The following scenario leads to total confusion of the platform firmware on some boxes (eg. HPC nx6325): * Hibernate with ACPI enabled * Resume passing "acpi=off" to the boot kernel To prevent this from happening it's necessary to check if ACPI is enabled (and enable it if that's not the case) _right_ _after_ control has been transfered from the boot kernel to the image kernel, before device_power_up() is called (ie. with interrupts disabled).  Enabling ACPI after calling device_power_up() turns out to be insufficient. For this reason, introduce new hibernation callback ->leave() that will be executed before device_power_up() by the restored image kernel.  To make it work, it also is necessary to move swsusp_suspend() from swsusp.c to disk.c (it's name is changed to "create_image", which is more up to the point).

* Hibernation: Arbitrary boot kernel support on x86_64Rafael J. Wysocki2007-10-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it possible to restore a hibernation image on x86_64 with the help of a kernel different from the one in the image. The idea is to split the core restoration code into two separate parts and to place each of them in a different page.  The first part belongs to the boot kernel and is executed as the last step of the image kernel's memory restoration procedure.  Before being executed, it is relocated to a safe page that won't be overwritten while copying the image kernel pages. The final operation performed by it is a jump to the second part of the core restoration code that belongs to the image kernel and has just been restored. This code makes the CPU switch to the image kernel's page tables and restores the state of general purpose registers (including the stack pointer) from before the hibernation. The main issue with this idea is that in order to jump to the second part of the core restoration code the boot kernel needs to know its address.  However, this address may be passed to it in the image header.  Namely, the part of the image header previously used for checking if the version of the image kernel is correct can be replaced with some architecture specific data that will allow the boot kernel to jump to the right address within the image kernel.  These data should also be used for checking if the image kernel is compatible with the boot kernel (as far as the memory restroration procedure is concerned). It can be done, for example, with the help of a "magic" value that has to be equal in both kernels, so that they can be regarded as compatible. Signed-off-by: Rafael J.

* serial: turn serial console suspend a boot rather than compile time optionAndres Salomon2007-10-181-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there's a CONFIG_DISABLE_CONSOLE_SUSPEND that allows one to stop the serial console from being suspended when the rest of the machine goes to sleep. This is incredibly useful for debugging power management-related things; however, having it as a compile-time option has proved to be incredibly inconvenient for us (OLPC). There are plenty of times that we want serial console to not suspend, but for the most part we'd like serial console to be suspended. This drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel boot parameter (no_console_suspend). By default, the serial console will be suspended along with the rest of the system; by passing 'no_console_suspend' to the kernel during boot, serial console will remain alive during suspend. For now, this is pretty serial console specific; further fixes could be applied to make this work for things like netconsole. Signed-off-by: Andres Salomon <dilinger@debian.org> Acked-by: "Rafael J.

* PM: Rework struct hibernation_opsRafael J. Wysocki2007-10-181-6/+32
| | | | | | | | | | | | | | | | | During hibernation we also need to tell the ACPI core that we're going to put the system into the S4 sleep state. For this reason, an additional method in 'struct hibernation_ops' is needed, playing the role of set_target() in 'struct platform_suspend_operations'. Moreover, the role of the .prepare() method is now different, so it's better to introduce another method, that in general may be different from .prepare(), that will be used to prepare the platform for creating the hibernation image (.prepare() is used anyway to notify the platform that we're going to enter the low power state after the image has been saved).

| | | | | | | | | | | | | | | | The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend.  Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'.  In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly.

There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

* Ext4: Uninitialized Block GroupsAndreas Dilger2007-10-171-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In pass1 of e2fsck, every inode table in the fileystem is scanned and checked, regardless of whether it is in use. This is this the most time consuming part of the filesystem check. The unintialized block group feature can greatly reduce e2fsck time by eliminating checking of uninitialized inodes. With this feature, there is a a high water mark of used inodes for each block group. Block and inode bitmaps can be uninitialized on disk via a flag in the group descriptor to avoid reading or scanning them at e2fsck time. A checksum of each group descriptor is used to ensure that corruption in the group descriptor's bit flags does not cause incorrect operation. The feature is enabled through a mkfs option mke2fs /dev/ -O uninit_groups A patch adding support for uninitialized block groups to e2fsprogs tools has been posted to the linux-ext4 mailing list. The patches have been stress tested with fsstress and fsx. In performance tests testing e2fsck time, we have seen that e2fsck time on ext3 grows linearly with the total number of inodes in the filesytem. In ext4 with the uninitialized block groups feature, the e2fsck time is constant, based solely on the number of used inodes rather than the total inode count. Since typical ext4 filesystems only use 1-10% of their inodes, this feature can greatly reduce e2fsck time for users. With performance improvement of 2-20 times, depending on how full the filesystem is. The attached graph shows the major improvements in e2fsck times in filesystems with a large total inode count, but few inodes in use. In each group descriptor if we have EXT4_BG_INODE_UNINIT set in bg_flags: Inode table is not initialized/used in this group. So we can skip the consistency check during fsck. EXT4_BG_BLOCK_UNINIT set in bg_flags: No block in the group is used. So we can skip the block bitmap verification for this group. We also add two new fields to group descriptor as a part of uninitialized group patch. __le16 bg_itable_unused; /* Unused inodes count */ __le16 bg_checksum; /* crc16(sb_uuid+group+desc) */ bg_itable_unused: If we have EXT4_BG_INODE_UNINIT not set in bg_flags then bg_itable_unused will give the offset within the inode table till the inodes are used. This can be used by fsck to skip list of inodes that are marked unused. bg_checksum: Now that we depend on bg_flags and bg_itable_unused to determine the block and inode usage, we need to make sure group descriptor is not corrupt. We add checksum to group descriptor to detect corruption. If the descriptor is found to be corrupt, we mark all the blocks and inodes in the group used.

For that reason every user that accesses the file server tree has to authenticate and attach to the server separately. Multiple users can share the same connection to the server. Currently v9fs does a single attach and executes all I/O operations as a single user. This makes using v9fs in multiuser environment unsafe as it depends on the client doing the permission checking. This patch improves the 9P2000 support by allowing every user to attach separately. The patch defines three modes of access (new mount option 'access'): - attach-per-user (access=user) (default mode for 9P2000.u) If a user tries to access a file served by v9fs for the first time, v9fs sends an attach command to the server (Tattach) specifying the user. If the attach succeeds, the user can access the v9fs tree. As there is no uname->uid (string->integer) mapping yet, this mode works only with the 9P2000.u dialect. - allow only one user to access the tree (access=<uid>) Only the user with uid can access the v9fs tree. Other users that attempt to access it will get EPERM error. - do all operations as a single user (access=any) (default for 9P2000) V9fs does a single attach and all operations are done as a single user. If this mode is selected, the v9fs behavior is identical with the current one. Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 554d284ba90bc2306c31e5363789f05c320969c3 added _GPF_NORETRY to floppy_64.h to prevent OOM killer on floppy DMA allocations. Apply the same to the 32 bit variant. Found during the attempt to unify the _32/_64 variants. Seperate commit to document the resulting code change.
