X-Received-From: 209.132.183.28 Cc: john cooper , Anthony Liguori Subject: [Qemu-devel] [PATCH 6/7] cpu model bug fixes and definition corrections X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org This patch adds Westmere as a qemu cpu model. The only additional guest visible feature of a Westmere relative to Nehalem is the inclusion of AES instructions. However as other non-ABI visible modifications exist along with fabrication changes, the CPUID data of the corresponding deployed silicon was altered slightly to reflect this. We've seen isolated cases where apparently unrelated yet slightly incoherent CPUID data has caused problems, most notably during guest boot. Providing Westmere as a model separate fro Nehalem allows us to more easily address such quirks.
