From e1e54f3fbee6c0652e19182f4c747de172cbe8b1 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Thu, 22 Nov 2012 13:31:03 -0200 Subject: [PATCH] target-i386: cpu: add missing flags to Haswell CPU model MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When adding the Haswell CPU model, I intended to make it a superset of the features present on the SandyBridge model, but I have removed the SEP and RDTSCP features from the feature list by mistake. This patch adds the missing SEP and RDTSCP features (that are present on SandyBridge) to Haswell.
