2006-06-26[PATCH] i386/x86-64: Emulate CPUID4 on AMDAndi Kleen
Intel systems report the cache level data from CPUID 4 in sysfs. Add a CPUID 4 emulation for AMD CPUs to report the same information for them. This allows programs to read this information in a uniform way. The AMD way to report this is less flexible so some assumptions are hardcoded (e.g. no L3) Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-26[PATCH] i386/x86-64: Use new official CPUID to get APICID/core split on AMD ↵Andi Kleen
platforms Previously the apicid<->coreid split was computed based on the max number of cores. Now use a new CPUID AMD defined for that. On most systems right now it should be 0 and the old method will be used. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-06-25[PATCH] Clean up and refactor i386 sub-architecture setupJeremy Fitzhardinge
Clean up and refactor i386 sub-architecture setup. This change moves all the code from the asm-i386/mach-*/setup_arch_pre/post.h headers, into arch/i386/mach-*/setup.c. mach-*/setup_arch_pre.h is renamed to setup_arch.h, and contains only things which should be in header files. It is purely code-motion; there should be no functional changes at all. Several functions in arch/i386/kernel/setup.c needed to be made non-static so that they're visible to the code in mach-*/setup.c. asm-i386/setup.h is used to hold the prototypes for these functions.

2006-06-23[PATCH] x86: kernel irq balance doesn't workZhang Yanmin
On i386, kernel irq balance doesn't work. 1) In function do_irq_balance, after kernel finds the min_loaded cpu but before calling set_pending_irq to really pin the selected_irq to the target cpu, kernel does a cpus_and with irq_affinity[selected_irq]. Later on, when the irq is acked, kernel would calls move_native_irq=>desc->handler->set_affinity to change the irq affinity. However, every function pointed by hw_interrupt_type->set_affinity(unsigned int irq, cpumask_t cpumask) always changes irq_affinity[irq] to cpumask. Next time when recalling do_irq_balance, it has to do cpu_ands again with irq_affinity[selected_irq], but irq_affinity[selected_irq] already becomes one cpu selected by the first irq balance. 2) Function balance_irq in file arch/i386/kernel/io_apic.c has the same issue.

2006-06-23[PATCH] fix x86 microcode driver handling of multiple matching revisionsJan Beulich
When multiple updates matching a given CPU are found in the update file, the action taken by the microcode update driver was inappropriate: - when lower revision microcode was found before matching or higher revision one, the driver would needlessly complain that it would not downgrade the CPU - when microcode matching the currently installed revision was found before newer revision code, no update would actually take place To change this behavior, the driver now concludes about possibly updates and issues messages only when the entire input was parsed. Additionally, this adds back (in different places, and conditionalized upon a new module option) some messages removed by a previous patch.

2006-06-14ACPI: ACPICA 20060331Bob Moore
Implemented header file support for the following additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support, all current and known ACPI tables are now defined in the ACPICA headers and are available for use by device drivers and other software. Implemented support to allow tables that contain ACPI names with invalid characters to be loaded. Previously, this would cause the table load to fail, but since there are several known cases of such tables on existing machines, this change was made to enable ACPI support for them. Also, this matches the behavior of the Microsoft ACPI implementation. https://bugzilla.novell.com/show_bug.cgi?id=147621 Fixed a couple regressions introduced during the memory optimization in the 20060317 release. The namespace node definition required additional reorganization and an internal datatype that had been changed to 8-bit was restored to 32-bit. (Valery Podrezov) Fixed a problem where a null pointer passed to acpi_ut_delete_generic_state() could be passed through to acpi_os_release_object which is unexpected. Such null pointers are now trapped and ignored, matching the behavior of the previous implementation before the deployment of acpi_os_release_object(). (Valery Podrezov, Fiodor Suietov) Fixed a memory mapping leak during the deletion of a SystemMemory operation region where a cached memory mapping was not deleted. This became a noticeable problem for operation regions that are defined within frequently used control methods. (Dana Meyers) Reorganized the ACPI table header files into two main files: one for the ACPI tables consumed by the ACPICA core, and another for the miscellaneous ACPI tables that are consumed by the drivers and other software. The various FADT definitions were merged into one common section and three different tables (ACPI 1.0, 1.0+, and 2.0) Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2006-06-08[PATCH] Fix HPET operation on 32-bit NVIDIA platformsAndy Currid
From: "Andy Currid" <ACurrid@nvidia.com> This patch fixes a kernel panic during boot that occurs on NVIDIA platforms that have HPET enabled. When HPET is enabled, the standard timer IRQ is routed to IOAPIC pin 2 and is advertised as such in the ACPI APIC table - but an earlier workaround in the kernel was ignoring this override. The fix is to honor timer IRQ overrides from ACPI when HPET is detected on an NVIDIA platform.

2006-05-30Revert "[PATCH] i386/x86_64: Force pci=noacpi on HP XW9300"Linus Torvalds
This reverts commit 5491d0f3e206beb95eeb506510d62a1dab462df1. As per Andi: "After some discussion with people who have the affected system it seems best to revert for 2.6.17. It broke a common BIOS workaround and PCI-X still doesn't work. Alternative is for people to change the BIOS which seems to be better right now." Signed-off-by: Linus Torvalds <torvalds@osdl.org>
