From mboxrd@z Thu Jan 1 00:00:00 1970 From: Paolo Bonzini Subject: [PATCH 0/4] KVM: x86: kvmclock cleanups for Hyper-V TSC page Date: Thu, 1 Sep 2016 17:26:11 +0200 Message-ID: <1472743575-123756-1-git-send-email-pbonzini@redhat.com> Cc: peterhornyack@google.com, rkrcmar@redhat.com, den@openvz.org, rkagan@virtuozzo.com To: linux-kernel@vger.kernel.org, kvm@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: kvm.vger.kernel.org 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.
