[kvm-devel] [resend] [PATCH] MSR_IA32_PERF_STATUS support

[Alexander G. <al...@cs...>]

This is a resend of a mail I sent on 01/10/2008. I did not receive any
response, so I assume it was lost.

The patch is really minor, does not break any compatibility (the MSR is
Intel family 13+) and makes Darwin work.

--- old mail ---

This patch adds support for the MSR MSR_IA32_PERF_STATUS. This is
required to boot Darwin.

I only implemented dummy support, as the real value would be of no
meaning to any OS I know so far anyway and is only implemented on very
recent Intel CPUs.
