KVM: x86: Add missing inline tag to kvm_read_and_reset_pf_reason

2011-01-12T09:23:27+00:00

May otherwise generates build warnings about unused
kvm_read_and_reset_pf_reason if included without CONFIG_KVM_GUEST
enabled.

KVM: Let host know whether the guest can handle async PF in non-userspace context.

2011-01-12T09:23:21+00:00

If guest can detect that it runs in non-preemptable context it can
handle async PFs at any time, so let host know that it can send async
PF even if guest cpu is not in userspace.

KVM: Handle async PF in a guest.

2011-01-12T09:23:16+00:00

When async PF capability is detected hook up special page fault handler
that will handle async page fault events and bypass other page faults to
regular page fault handler. Also add async PF handling to nested SVM
emulation. Async PF always generates exit to L1 where vcpu thread will
be scheduled out until page is available.

KVM: Add PV MSR to enable asynchronous page faults delivery.

2011-01-12T09:23:12+00:00

Guest enables async PF vcpu functionality using this MSR.

KVM paravirt: Move kvm_smp_prepare_boot_cpu() from kvmclock.c to kvm.c.

2011-01-12T09:23:10+00:00

Async PF also needs to hook into smp_prepare_boot_cpu so move the hook
into generic code.

KVM: Move kvm_guest_init out of generic code

2010-10-24T08:50:49+00:00

Currently x86 is the only architecture that uses kvm_guest_init(). With
PowerPC we're getting a second user, but the signature is different there
and we don't need to export it, as it uses the normal kernel init framework.

So let's move the x86 specific definition of that function over to the x86
specfic header file.

x86, paravirt: don't compute pvclock adjustments if we trust the tsc

If the HV told us we can fully trust the TSC, skip any
correction

KVM: x86: add new KVMCLOCK cpuid feature

2010-05-19T08:41:02+00:00

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 kvmclock

2010-05-19T08:41:01+00:00

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.
