From c453ee7be0ea682f1b20bc2b9e90cc17f678e987 Mon Sep 17 00:00:00 2001 Message-Id: From: Andre Przywara Date: Fri, 19 Oct 2012 17:01:57 -0300 Subject: [PATCH 1/2] i386/cpu: name new CPUID bits Upstream status: submitted Update QEMU's knowledge of CPUID bit names. This allows to enable/disable those new features on QEMU's command line when using KVM and prepares future feature enablement in QEMU. This adds F16C, RDRAND, LWP, TBM, TopoExt, PerfCtr_Core, PerfCtr_NB, FSGSBASE, BMI1, AVX2, BMI2, ERMS, InvPCID, RTM, RDSeed and ADX. Sources where the AMD BKDG for Family 15h/Model 10h and the Linux kernel for the leaf 7 bits.
