From 9593b95415b6da77211860e76987c988c08e19d4 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Thu, 21 Aug 2014 19:58:16 +0200 Subject: [PATCH 1/3] target-i386: Broadwell CPU model MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Message-id: <1408651097-24190-2-git-send-email-ehabkost@redhat.com> Patchwork-id: 60670 O-Subject: [RHEL7.1 qemu-kvm PATCH 1/2] target-i386: Broadwell CPU model Bugzilla: 1116117 RH-Acked-by: Bandan Das RH-Acked-by: Markus Armbruster RH-Acked-by: Paolo Bonzini This adds a new CPU model named "Broadwell". It has all the features from Haswell, plus PREFETCHW, RDSEED, ADX, SMAP. PREFETCHW was already supported as "3dnowprefetch". [Already supported by RHEL-7 kernel, too] RDSEED, ADX was added on Linux v3.15-rc1. [RDSEED: RHEL-7 kernel commit c4311bc8c9167a3d7011aff8728fd8067404246f] [ADX: RHEL-7 kernel commit fe5f6cdf4428dcd01f5b060b31eabe44c2f5e468] SMAP was added on Linux v3.15-rc2. [RHEL-7 kernel commit 890edaefc84a2596a3f17d1e9967935a1984e302] About migration support: * SMAP state is a single bit on CR4 which is already migrated; * PREFETCHW, RDSEED, ADX have no new state.
