Subject: [V0 PATCH 5/6] AMD-PVH: Support TSC_MODE_NEVER_EMULATE for PVH
Date: Fri, 15 Aug 2014 18:53:15 -0700 [thread overview]
Message-ID: <1408153996-16425-6-git-send-email-mukesh.rathor@oracle.com> (raw)
In-Reply-To: <1408153996-16425-1-git-send-email-mukesh.rathor@oracle.com>
On AMD, MSR_AMD64_TSC_RATIO must be set for rdtsc instruction in guest
to properly read the cpu tsc. To that end, set tsc_khz in struct domain.
