* [PATCH] x86_64: Fix the node cpumask of a cpu going downRavikiran G Thirumalai2006-02-07
| | | | | | | | | | | | | | | | | | | | | | | Currently, x86_64 and ia64 arches do not clear the corresponding bits in the node's cpumask when a cpu goes down or cpu bring up is cancelled. This is buggy since there are pieces of common code where the cpumask is checked in the cpu down code path to decide on things (like in the slab down path). PPC does the right thing, but x86_64 and ia64 don't (This was the reason Sonny hit upon a slab bug during cpu offline on ppc and could not reproduce on other arches). This patch fixes it for x86_64. I won't attempt ia64 as I cannot test it. Credit for spotting this should go to Alok. (akpm: this was applied, then reverted. But it's OK now because we now use for_each_cpu() in the right places).

* [PATCH] x86_64: IOMMU printk cleanupJon Mason2006-02-04
| | | | | | | | | | | | | | | | | | | | This patch contains a printk reorder to remove the current problem of displaying "PCI-DMA: Disabling IOMMU." and then "PCI-DMA: using GART IOMMU" 20 lines later in dmesg. It also constains a printk reorder in swiotlb to state swiotlb enablement prior to describing the location of the bounce buffers, and a printk reorder to state gart enablement prior to describing the aperature. Also constains a whitespace cleanup in arch/x86_64/kernel/setup.c Tested (along with patch 2/2) on dual opteron with gart enabled, iommu=soft, and iommu=off.

* [PATCH] x86_64: Let impossible CPUs point to reference per cpu dataAndi Kleen2006-02-04
| | | | | | | | | | | | | | Hack for 2.6.16. In 2.6.17 all code that uses NR_CPUs should be audited and changed to only touch possible CPUs. Don't mark the reference per cpu data init data (so it stays around after boot) and point all impossible CPUs to it. This way they reference some valid - although shared memory. Usually this is only initialization like INIT_LIST_HEADs and there won't be races because these CPUs never run. Still somewhat hackish.

* [PATCH] x86_64: Calibrate APIC timer using PM timerAndi Kleen2006-02-04
| | | | | | | | | | | | | | | | | | | | | On some broken motherboards (at least one NForce3 based AMD64 laptop) the PIT timer runs at a incorrect frequency. This patch adds a new option "apicpmtimer" that allows to use the APIC timer and calibrate it using the PMTimer. It requires the earlier patch that allows to run the main timer from the APIC. Specifying apicpmtimer implies apicmaintimer. The option defaults to off for now. I tested it on a few systems and the resulting APIC timer frequencies were usually a bit off, but always <1%, which should be tolerable. TBD figure out heuristic to enable this automatically on the affected systems TBD perhaps do it on all NForce3s or using DMI?

* [PATCH] x86_64: When allocation of merged SG lists fails in the IOMMU don't ↵Kevin VanMaren2006-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | merge [ AK: I redid Kevin's fix to be simpler, but the idea and original analysis of the problem is from Kevin] This avoid allocation failures on some SATA systems like Nvidia CK8 when the IOMMU gets fragmented. Modern SATA devices have quite large queues (128 entries) and the FS with ext2/3 is good enough now that it often passes whole 128 page sg lists down to the driver. These require 512K of continuous free space in the IOMMU aperture to map when merged. When the IOMMU is fragmented this could lead to spurious IO errors due to failing mappings. Short term fix is to just try to map the SG list again unmerged page by page - this way fragmentation doesn't matter anymore. The code for that was already there, but it just wasn't enabled for the merge case. According to Kevin at least the Nvidia device doesn't seem to benefit from merging much anyways, so the only slowdown is from trying to do an unnecessary merge attempt. Kevin plans to implement better fragmentation avoidance in the future, but that wouldn't be 2.6.16 material. TBD: should add some statistic counters to count how often that really happens.

| | | | | | | | | | | | | | | | | | | | | | Another piece from the no-idle-tick patch. This can be enabled with the "apicmaintimer" option. This is mainly useful when the PIT/HPET interrupt is unreliable. Note there are some systems that are known to stop the APIC timer in C3. For those it will never work, but this case should be automatically detected. It also only works with PM timer right now. When HPET is used the way the main timer handler computes the delay doesn't work. It should be a bit more efficient because there is one less regular interrupt to process on the boot processor.

The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued. This matches the behavior of acpi_ut_allocate(). Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Since there were hard-coded numbers in the file, the patch also adds a mechanism to avoid these (otherwise potential future changes would again and again require adjusting these numbers).
