[PATCH] x86: Refactor thermal throttle processing

2006-09-26T08:52:42Z

Refactor the event processing (syslog messaging and rate limiting) into separate file therm_throt.c. This allows consistent reporting of CPU thermal throttle events. After ACK'ing the interrupt, if the event is current, the user (p4.c/mce_intel.c) calls therm_throt_process to log (and rate limit) the event. If that function returns 1, the user has the option to log things further (such as to mce_log in x86_64). AK: minor cleanup Signed-off-by: Dmitriy Zavin Signed-off-by: Andi Kleen

[PATCH] i386/x86-64: Make all early PCI scans dependent on CONFIG_PCI

2006-09-26T08:52:41Z

This is useful on systems with broken PCI bus. Affects various scans in x86-64 and i386's early ACPI quirk scan. Cc: gregkh@suse.de Cc: len.brown@intel.com Cc: Trammell Hudson Signed-off-by: Andi Kleen

[PATCH] Move early chipset quirks out to new file

2006-09-26T08:52:30Z

They did not really belong into io_apic.c. Move them into a new file and clean it up a bit. Also remove outdated ATI quirk that was obsolete, Signed-off-by: Andi Kleen

[PATCH] Remove all ifdefs for local/io apic

2006-09-26T08:52:29Z

IO-APIC or local APIC can only be disabled at runtime anyways and Kconfig has forced these options on for a long time now. The Kconfigs are kept only now for the benefit of the shared acpi boot.c code. Signed-off-by: Andi Kleen

[PATCH] lockdep: stacktrace subsystem, x86_64 support

2006-07-03T22:27:02Z

Framework to generate and save stacktraces quickly, without printing anything to the console. x86_64 support. Signed-off-by: Ingo Molnar Signed-off-by: Arjan van de Ven Cc: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] audit syscall classes

2006-07-01T11:44:10Z

Allow to tie upper bits of syscall bitmap in audit rules to kernel-defined sets of syscalls. Infrastructure, a couple of classes (with 32bit counterparts for biarch targets) and actual tie-in on i386, amd64 and ia64. Signed-off-by: Al Viro

[PATCH] x86_64: Calgary IOMMU - Calgary specific bits

2006-06-26T17:48:19Z

This patch hooks Calgary into the build, the x86-64 IOMMU initialization paths, and introduces the Calgary specific bits. The implementation draws inspiration from both PPC (which has support for the same chip but requires firmware support which we don't have on x86-64) and gart. Calgary is different from gart in that it support a translation table per PHB, as opposed to the single gart aperture. Changes from previous version: * Addition of boot-time disablement for bus-level translation/isolation (e.g, enable userspace DMA for things like X) * Usage of newer IOMMU abstraction functions Signed-off-by: Muli Ben-Yehuda Signed-off-by: Jon Mason Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] x86_64: Rename IOMMU option, fix help and mark option embedded.

2006-06-26T17:48:17Z

- Rename the GART_IOMMU option to IOMMU to make clear it's not just for AMD - Rewrite the help text to better emphatise this fact - Make it an embedded option because too many people get it wrong. To my astonishment I discovered the aacraid driver tests this symbol directly. This looks quite broken to me - it's an internal implementation detail of the PCI DMA API. Can the maintainer please clarify what this test was intended to do? Cc: linux-scsi@vger.kernel.org Cc: alan@redhat.com Cc: markh@osdl.org Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] x86_64: Clean and enhance up K8 northbridge access code

2006-06-26T17:48:15Z

- Factor out the duplicated access/cache code into a single file * Shared between i386/x86-64. - Share flush code between AGP and IOMMU * Fix a bug: AGP didn't wait for end of flush before - Drop 8 northbridges limit and allocate dynamically - Add lock to serialize AGP and IOMMU GART flushes - Add PCI ID for next AMD northbridge - Random related cleanups The old K8 NUMA discovery code is unchanged. New systems should all use SRAT for this. Cc: "Navin Boppuri" Cc: Dave Jones Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] x86_64: x86_64 version of the smp alternative patch.

2006-06-26T17:48:14Z

Changes are largely identical to the i386 version: * alternative #define are moved to the new alternative.h file. * one new elf section with pointers to the lock prefixes which can be nop'ed out for non-smp. * two new elf sections simliar to the "classic" alternatives to replace SMP code with simpler UP code. * fixup headers to use alternative.h instead of defining their own LOCK / LOCK_PREFIX macros. The patch reuses the i386 version of the alternatives code to avoid code duplication. The code in alternatives.c was shuffled around a bit to reduce the number of #ifdefs needed. It also got some tweaks needed for x86_64 (vsyscall page handling) and new features (noreplacement option which was x86_64 only up to now). Debug printk's are changed from compile-time to runtime.
