From mboxrd@z Thu Jan 1 00:00:00 1970 From: Don Slutz Subject: [PATCH v7 17/17] target-i386: target-i386: Add VMWare CPUID Timing information in -machine pc, accel=tcg Date: Fri, 12 Oct 2012 15:56:22 -0400 Message-ID: <1350071782-23078-18-git-send-email-Don@CloudSwitch.com> References: <1350071782-23078-1-git-send-email-Don@CloudSwitch.com> Mime-Version: 1.0 Content-Type: text/plain Cc: Don Slutz To: , , , , , , , , Return-path: In-Reply-To: <1350071782-23078-1-git-send-email-Don@CloudSwitch.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+gceq-qemu-devel=gmane.org@nongnu.org Sender: qemu-devel-bounces+gceq-qemu-devel=gmane.org@nongnu.org List-Id: kvm.vger.kernel.org Part of "target-i386: Add way to expose VMWare CPUID" This is EAX and EBX data for 0x40000010. Add new #define CPUID_HV_TIMING_INFO for this. The best documentation I have found is: http://article.gmane.org/gmane.comp.emulators.kvm.devel/22643 And a test under ESXi 4.0 shows that VMware is setting this data.
