From 838815a78785022f6611e5c48386567aea7b818b Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Tue, 11 May 2010 12:17:44 -0400 Subject: [PATCH] x86: KVM guest: Try using new kvm clock msrs We now added a new set of clock-related msrs in replacement of the old ones. In theory, we could just try to use them and get a return value indicating they do not exist, due to our use of kvm_write_msr_save. However, kvm clock registration happens very early, and if we ever try to write to a non-existant MSR, we raise a lethal #GP, since our idt handlers are not in place yet. So this patch tests for a cpuid feature exported by the host to decide which set of msrs are supported.
