From 15c5cb87402b646349a6cc535cc74cefd01dbf1e Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Thu, 5 Oct 2017 22:39:08 +0200 Subject: [PATCH 25/27] target-i386/cpu: Add new EPYC CPU model RH-Author: Eduardo Habkost Message-id: <20171005223908.431-3-ehabkost@redhat.com> Patchwork-id: 76833 O-Subject: [RHEL-7.5 qemu-kvm PATCH 2/2] target-i386/cpu: Add new EPYC CPU model Bugzilla: 1450396 RH-Acked-by: Paolo Bonzini RH-Acked-by: Igor Mammedov RH-Acked-by: Bandan Das From: Brijesh Singh Add a new base CPU model called 'EPYC' to model processors from AMD EPYC family (which includes EPYC 76xx,75xx,74xx, 73xx and 72xx). The following features bits have been added/removed compare to Opteron_G5 Added: monitor, movbe, rdrand, mmxext, ffxsr, rdtscp, cr8legacy, osvw, fsgsbase, bmi1, avx2, smep, bmi2, rdseed, adx, smap, clfshopt, sha xsaveopt, xsavec, xgetbv1, arat Removed: xop, fma4, tbm Backport notes: * ARAT feature removed. It is already disabled by the rhel7.2.0 compat code in qemu-kvm-rhev, so it keeps migration compatibility with qemu-kvm-rhev.
