[PATCH 0/4] KVM: x86: kvmclock cleanups for Hyper-V TSC page

From: Paolo Bonzini
Date: Thu Sep 01 2016 - 11:26:54 EST


This implements the plan that we discussed at KVM Forum. Patch 3
implements a new function that returns the current value of kvmclock as
read by the guest. The function is then used to provide the Hyper-V
time reference counter. Now that the reference counter is synchronized
with kvmclock, the TSC page can be supported nicely.
