[PATCH] i386: mark cpu cache functions as __cpuinit

2006-09-26T08:52:36Z

Mark i386-specific cpu cache functions as __cpuinit. They are all only called from arch/i386/common.c:display_cache_info() that already is marked as __cpuinit. Signed-off-by: Magnus Damm Signed-off-by: Andi Kleen

[PATCH] i386: remove redundant generic_identify() calls when identifying cpus

2006-09-26T08:52:36Z

cpu_dev->c_identify is only called from arch/i386/common.c:identify_cpu(), and this after generic_identify() already has been called. There is no need to call this function twice and hook it in c_identify - but I may be wrong, please double check before applying. This patch also removes generic_identify() from cpu.h to avoid unnecessary future nesting. Signed-off-by: Magnus Damm Signed-off-by: Andi Kleen

[PATCH] x86_64: i386/x86-64 Add nmi watchdog support for new Intel CPUs

2006-06-26T17:48:22Z

Intel now has support for Architectural Performance Monitoring Counters ( Refer to IA-32 Intel Architecture Software Developer's Manual http://www.intel.com/design/pentium4/manuals/253669.htm ). This feature is present starting from Intel Core Duo and Intel Core Solo processors. What this means is, the performance monitoring counters and some performance monitoring events are now defined in an architectural way (using cpuid). And there will be no need to check for family/model etc for these architectural events. Below is the patch to use this performance counters in nmi watchdog driver. Patch handles both i386 and x86-64 kernels. Signed-off-by: Venkatesh Pallipadi Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] i386: devinit should be cpuinit

2006-03-23T15:38:04Z

Several places in arch/i386/kernel/cpu and kernel/cpu were using __devinit when they should have been __cpuinit. Fixing that saves ~4K when CONFIG_HOTPLUG && !CONFIG_HOTPLUG_CPU.

[PATCH] i386/x86-64: Generalize X86_FEATURE_CONSTANT_TSC flag

2006-01-12T03:01:12Z

Define it for i386 too. This is a synthetic flag that signifies that the CPU's TSC runs at a constant P state invariant frequency. Fix up the logic on x86-64/i386 to set it on all known CPUs. Use the AMD defined bit to set it on future AMD CPUs. Cc: venkatesh.pallipadi@intel.com Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] x86-64/i386: Intel HT, Multi core detection fixes

2005-11-15T03:55:16Z

Fields obtained through cpuid vector 0x1(ebx[16:23]) and vector 0x4(eax[14:25], eax[26:31]) indicate the maximum values and might not always be the same as what is available and what OS sees. So make sure "siblings" and "cpu cores" values in /proc/cpuinfo reflect the values as seen by OS instead of what cpuid instruction says. This will also fix the buggy BIOS cases (for example where cpuid on a single core cpu says there are "2" siblings, even when HT is disabled in the BIOS. http://bugzilla.kernel.org/show_bug.cgi?id=4359) Signed-off-by: Suresh Siddha Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds
