From b2042020c32b74069fa5365b5e966537aaba8cf6 Mon Sep 17 00:00:00 2001 From: Jiri Denemark <jdenemar@redhat.com> Date: Tue, 9 Jan 2018 21:41:31 +0100 Subject: [PATCH 14/15] cpu: Add Skylake-Client-IBRS CPU model This is a variant of Skylake-Client with indirect branch prediction protection. The only difference between Skylake-Client and Skylake-Client-IBRS is the added "spec-ctrl" feature.
