From 4806c6609872f4b642da379b7d7e54e9b0f9c09f Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Mon, 16 Sep 2013 20:39:57 +0200 Subject: [PATCH 08/25] pc: RHEL-6 don't have RDTSCP RH-Author: Eduardo Habkost Message-id: <1379363997-11783-5-git-send-email-ehabkost@redhat.com> Patchwork-id: 54399 O-Subject: [RHEL7 PATCH 4/4] pc: RHEL-6 don't have RDTSCP Bugzilla: 918907 RH-Acked-by: Bandan Das RH-Acked-by: Markus Armbruster RH-Acked-by: Miroslav Rezanina Bugzilla: 918907 Upstream status: not applicable (RHEL-6-only quirk that is not going to be included upstream) Brew build: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=6290888 The phenom and Opteron_G[123] CPU models don't have RDTSCP enabled on RHEL-6, so we have to explicitly disable it on pc_init_rhel650() to keep compatibility.
