* KVM: PPC: Add documentation for magic page enhancementsAlexander Graf2010-10-241-0/+14
| | | | | | | This documents how to detect additional features inside the magic page when a guest maps it. Signed-off-by: Alexander Graf <agraf@suse.de>
* KVM: PPC: Add mtsrin PV codeAlexander Graf2010-10-241-0/+3
| | | | | | | | This is the guest side of the mtsr acceleration. Using this a guest can now call mtsrin with almost no overhead as long as it ensures that it only uses it with (MSR_IR|MSR_DR) == 0. Linux does that, so we're good. Signed-off-by: Alexander Graf <agraf@suse.de>
