2009-11-23x86, cpu: mv display_cacheinfo -> cpu_detect_cache_sizesBorislav Petkov1-1/+1
display_cacheinfo() doesn't display anything anymore and it is used to detect CPU cache sizes. Rename it accordingly. Signed-off-by: Borislav Petkov <petkovbb@gmail.com> LKML-Reference: <20091121130145.GA31357@liondog.tnic> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2009-03-14x86/centaur: merge 32 & 64 bit versionSebastian Andrzej Siewior1-7/+27
there should be no difference, except: * the 64bit variant now also initializes the padlock unit. * ->c_early_init() is executed again from ->c_init() * the 64bit fixups made into 32bit path.

2009-03-12x86: move various CPU initialization objects into .cpuinit.rodataJan Beulich1-1/+1
Impact: debuggability and micro-optimization Putting whatever is possible into the (final) .rodata section increases the likelihood of catching memory corruption bugs early, and reduces false cache line sharing.

2008-09-04x86: remove cpu_vendor_devYinghai Lu1-1/+2
1. add c_x86_vendor into cpu_dev 2. change cpu_devs to static 3. check c_x86_vendor before put that cpu_dev into array 4. remove alignment for 64bit 5. order the sequence in cpu_devs according to link sequence... so could put intel at first, then amd...

2008-09-04x86: move mtrr cpu cap setting early in early_init_xxxxYinghai Lu1-0/+11
Krzysztof Helt found MTRR is not detected on k6-2 root cause: we moved mtrr_bp_init() early for mtrr trimming, and in early_detect we only read the CPU capability from cpuid, so some cpu doesn't have that bit in cpuid. So we need to add early_init_xxxx to preset those bit before mtrr_bp_init for those earlier cpus. this patch is for v2.6.27 Reported-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-17x86: use ELF section to list CPU vendor specific codeThomas Petazzoni1-5/+1
Replace the hardcoded list of initialization functions for each CPU vendor by a list in an ELF section, which is read at initialization in arch/x86/kernel/cpu/cpu.c to fill the cpu_devs[] array. The ELF section, named .x86cpuvendor.init, is reclaimed after boot, and contains entries of type "struct cpu_vendor_dev" which associates a vendor number with a pointer to a "struct cpu_dev" structure. This first modification allows to remove all the VENDOR_init_cpu() functions. This patch also removes the hardcoded calls to early_init_amd() and early_init_intel(). Instead, we add a "c_early_init" member to the cpu_dev structure, which is then called if not NULL by the generic CPU initialization code. Unfortunately, in early_cpu_detect(), this_cpu is not yet set, so we have to use the cpu_devs[] array directly. This patch is part of the Linux Tiny project, and is needed for further patch that will allow to disable compilation of unused CPU support code.
