Revision e1f829b6f453c7985cfdfab616994b4051c3d788 authored by Alexander Graf on 20 December 2009, 21:24:06 UTC, committed by Marcelo Tosatti on 25 January 2010, 14:26:36 UTC
Embedded PowerPC KVM has an exit timing implementation to track and evaluate how much time was spent in which exit path. For Book3S, we don't implement it. So let's not expose it as a config option either. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
