From c8acc380be7c7bb489037c927a2a5c217535f864 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Wed, 14 Nov 2012 16:28:52 -0200 Subject: [PATCH] target-i386/cpu: Name new CPUID bits MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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, PCID, InvPCID, RTM, RDSeed and ADX. Sources where the AMD BKDG for Family 15h/Model 10h, Intel Software Developer Manual, and the Linux kernel for the leaf 7 bits.
