x86: Require MOVBE feature in cpuid when we use it

2013-01-29T00:59:55+00:00

Add MOVBE to asm/required-features.h so we check for it during startup and don't bother checking for it later. CONFIG_MATOM is used because it corresponds to -march=atom in the Makefiles. If the rules get more complicated it may be necessary to make this an explicit Kconfig option which uses -mmovbe/-mno-movbe to control the use of this instruction explicitly.

x86, cpu: Support the features flags in new CPUID leaf 7

2010-07-08T00:29:18+00:00

Intel has defined CPUID leaf 7 as the next set of feature flags (see the AVX specification, version 007). Add support for this new feature flags word. Signed-off-by: H. Peter Anvin LKML-Reference:

x86-64: non-paravirt systems always has PSE and PGE

2009-03-30T16:25:31+00:00

A paravirtualized system may not have PSE or PGE available to guests, so they are not required features. However, without paravirt we can assume that any x86-64 implementation will have them available. Signed-off-by: Jeremy Fitzhardinge

x86-64: remove PGE from must-have feature list

2009-03-30T16:25:29+00:00

PGE may not be available when running paravirtualized, so test the cpuid bit before using it. Signed-off-by: Jeremy Fitzhardinge

x86: Fix ASM_X86__ header guards

2008-10-23T05:55:23+00:00

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin
