Subject: [PATCH 0/6] KVM support for TSC scaling
Date: Wed, 9 Feb 2011 18:29:38 +0100 [thread overview]
Message-ID: <1297272584-22689-1-git-send-email-joerg.roedel@amd.com> (raw)
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.
Thanks,
Joerg
