| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kexec boot is not successful on some power machines since all CPUs are getting removed from global interrupt queue (GIQ) before kexec boot. Some systems always expect at least one CPU in GIQ. Hence, this patch will make sure that only secondary CPUs are removed from GIQ.

* | [PATCH] Xmon bug fix for soft-resetHaren Myneni2005-08-021-0/+3
|/ | | | | | | | | | | | | | | | | | For soft reset during system hang, got an error "CPU did not take control" for some CPUs even though they responded to soft-reset (called SystemReset, die and called debugger - xmon). First these CPUs entered into xmon by IPI callback and then got a soft-reset exception and re-entered into xmon again. The first CPU which re-entered into xmon got the output lock and made into xmon successfully without unlocking. Hence, the next CPU(s) which re-entered into xmon try to acquire a lock (get_output_lock). Therefore, we can not view state of those CPU(s).

* [PATCH] ppc64: POWER 4 fails to boot with NUMAMike Kravetz2005-08-011-1/+6
| | | | | | | | | | | | | | | | | If CONFIG_NUMA is set, some POWER 4 systems will fail to boot. This is because of special processing needed to handle invalid node IDs (0xffff) on POWER 4. My previous patch to handle memory 'holes' within nodes forgot to add this special case for POWER 4 in one place. In reality, I'm not sure that configuring the kernel for NUMA on POWER 4 makes much sense. Are there POWER 4 based systems with NUMA characteristics that are presented by the firmware? But, distros want one kernel for all systems so NUMA is on by default in their kernels. The patch handles those cases.

* [PATCH] m32r: Fix local-timer event handlingHirokazu Takata2005-08-011-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a scheduling problem of the m32r SMP kernel; A process rarely stopped and gave no responding but the other process have been handled by the other CPU still lives, then if we did something in the other terminal or something like that, the stopped process came back to life and continued its operation... (ex. LMbench: lat_sig) In the m32r SMP kernel, a local-timer event is delivered by using an IPI(inter processor interrupts); LOCAL_TIMER_IPI. And a function smp_send_timer() is prepared to send the LOCAL_TIMER_IPI from the current CPU to the other CPUs. The funtion smp_send_timer() was placed and used in do_IRQ() in former times (before 2.6.10-rc3-mm1 kernel), however, it was unintentionally removed when arch/m32r/kernel/irq.c was modified to employ the generic hardirq framework (CONFIG_GENERIC_HARDIRQ) in my previous patch.

| | | | | | | | | | | | We know that the randomisation slows down some workloads on Transmeta CPUs by quite large amounts.

* [PATCH] remove sys_set_zone_reclaim()Ingo Molnar2005-08-012-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes sys_set_zone_reclaim() for now. While i'm sure Martin is trying to solve a real problem, we must not hard-code an incomplete and insufficient approach into a syscall, because syscalls are pretty much for eternity. I am quite strongly convinced that this syscall must not hit v2.6.13 in its current form. Firstly, the syscall lacks basic syscall design: e.g. it allows the global setting of VM policy for unprivileged users. (!) [ Imagine an Oracle installation and a SAP installation on the same NUMA box fighting over the 'optimal' setting for this flag. What will they do? Will they try to set the flag to their own preferred value every second or so? ] Secondly, it was added based on a single datapoint from Martin: http://marc.theaimsgroup.com/?l=linux-mm&m=111763597218177&w=2 where Martin characterizes the numbers the following way: ' Run-to-run variability for "make -j" is huge, so these numbers aren't terribly useful except to see that with reclaim the benchmark still finishes in a reasonable amount of time. ' in other words: the fundamental problem has likely not been solved, only a tendential move into the right direction has been observed, and a handful of numbers were picked out of a set of hugely variable results, without showing the variability data. How much variance is there run-to-run? I'd really suggest to first walk the walk and see what's needed to get stable & predictable kernel compilation numbers on that NUMA box, before adding random syscalls to tune a particular aspect of the VM ... which approach might not even matter once the whole picture has been analyzed and understood! The third, most important point is that the syscall exposes VM tuning internals in a completely unstructured way. What sense does it make to have a _GLOBAL_ per-node setting for 'should we go to another node for reclaim'? If then it might make sense to do this per-app, via numalib or so. The change is minimalistic in that it doesnt remove the syscall and the underlying infrastructure changes, only the user-visible changes. We could perhaps add a CAP_SYS_ADMIN-only sysctl for this hack, a'ka /proc/sys/vm/swappiness, but even that looks quite counterproductive when the generic approach is that we are trying to reduce the number of external factors in the VM balance picture.

* [PATCH] x86_64: avoid wasting IRQs patch updateNatalie.Protasevich@unisys.com2005-07-301-2/+15
| | | | | | | | | | | | | | The patch adds boundary check for the MAX_GSI_NUM. Same as the update for i386, the patch addresses a problem with ACPI SCI IRQ. The patch corrects the code such that SCI IRQ is skipped and duplicate entry is avoided. The VIA chipset uses 4-bit IRQ register for internal interrupt routing, and therefore cannot handle IRQ numbers assigned to its devices. The patch corrects this problem by allowing PCI IRQs below 16.

There is a window during processor startup during which the target cpu has started and before it has initialized it's interrupt vectors so it can properly process an interrupt. Receveing an interrupt during that window will triple fault the cpu and do other nasty things. Why cli does not protect us from that is beyond me. The simple fix is to match ia64 and provide a smp_call_function_single. Which avoids the broadcast and is more efficient. This certainly fixes the problem of getting stuck on boot which was very easy to trigger on my SMP Hyperthreaded Xeon, and I think it fixes it for the right reasons.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While reserving KVA for lmem_maps of node, we have to make sure that node_remap_start_pfn[] is aligned to a proper pmd boundary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the standard hardware page table manipulation macros. This is possible now that linux works with all 4 levels of the page tables. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an uncensored copy of code from i386 to x86_64 I wound up with inline assembly with the wrong constraints. Use input constraints instead of output constraints. So I know the assembler will do the right thing specify the size of the operand lidtq and lgdtq instead of just lidt and lgdt. Make load_segments use an input constraint, and delete the macro fun. Without having to reload %cs like I do on i386 this code is noticeably simpler. Signed-off-by: Eric W.

Playing in the trampoline code I have seen a couple of instances where lgdt get the wrong size (because the trampolines run in 16bit mode) so use lgdtl and lidtl to be explicit. Additionally gcc-3.3 and gcc-3.4 want's an lvalue for a memory argument and it doesn't think an array of characters is an lvalue so use a packed structure instead. Signed-off-by: Eric W.
