Subject: [PATCH v3 1/7] x86/pvh: fix TSC mode setup for PVH Dom0
Date: Tue, 30 Oct 2018 16:41:17 +0100	[thread overview]
Message-ID: <20181030154123.4218-2-roger.pau@citrix.com> (raw)
In-Reply-To: <20181030154123.4218-1-roger.pau@citrix.com>

A PVH Dom0 might use TSC scaling or other HVM specific TSC
adjustments, so only short-circuit the TSC setup for a classic PV
Dom0.
