* x86, paravirt: don't compute pvclock adjustments if we trust the tscGlauber Costa2010-05-191-0/+5
| | | | | | | | | If the HV told us we can fully trust the TSC, skip any correction Signed-off-by: Glauber Costa <glommer@redhat.com> Acked-by: Zachary Amsden <zamsden@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: x86: add new KVMCLOCK cpuid featureGlauber Costa2010-05-191-0/+4
| | | | | | | | | | This cpuid, KVM_CPUID_CLOCKSOURCE2, will indicate to the guest that kvmclock is available through a new set of MSRs. The old ones are deprecated.

* KVM: x86: change msr numbers for kvmclockGlauber Costa2010-05-191-0/+4
| | | | | | | | | | Avi pointed out a while ago that those MSRs falls into the pentium PMU range. So the idea here is to add new ones, and after a while, deprecate the old ones.

* x86: Fix ASM_X86__ header guardsH. Peter Anvin2008-10-221-3/+3
| | | | | | | | | 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 <hpa@zytor.com>
