Message-ID: <1297272584-22689-1-git-send-email-joerg.roedel@amd.com> Date: Wed, 9 Feb 2011 18:29:38 +0100 From: Joerg Roedel <joerg.roedel@....com> To: Avi Kivity <avi@...hat.com>, Marcelo Tosatti <mtosatti@...hat.com> CC: <kvm@...r.kernel.org>, <linux-kernel@...r.kernel.org>, Zachary Amsden <zamsden@...hat.com> Subject: [PATCH 0/6] KVM support for TSC scaling Hi Avi, Marcelo, here is the patch-set to implement the TSC-scaling feature of upcoming AMD CPUs. When this feature is supported the CPU provides a new MSR which holds a multiplier for the hardware TSC which is applied on the value rdtsc[p] and reads of MSR 0x10. This feature can be used to emulate a given tsc frequency for the guest. Patch 1 is not directly related to this patch-set because it only fixes a bug which prevented me from testing these patches. In fact it fixes the same bug Andre sent a patch for. But after the discussion about his patch he told me to just post my patch and thus here it is.
