Date: Fri, 24 Oct 2008 17:21:27 -0700 Message-Id: <1224894087.28224.69.camel@alok-dev1> Mime-Version: 1.0 X-Mailer: Evolution 2.8.0 (2.8.0-40.el5_1.1) Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 613 Lines: 17 Hi, These patches define a framework for hypervisor detection and setting of hypervisor feature bits. We define a X86_FEATURE_TSC_RELIABLE bit which is a synthetic bit. This is set when running under VMware. This feature bit is used to skip TSC checks which can fail on virtualization platform due to timing differences when running on virtual cpus.
