File 7bb4ce97-cpu-Add-Broadwell-IBRS-CPU-model.patch of Package libvirt.10106
From 7bb4ce9761dfbd1620ddffb26fbd6f0ff1fedf3f Mon Sep 17 00:00:00 2001 From: Jiri Denemark <jdenemar@redhat.com> Date: Tue, 9 Jan 2018 21:36:28 +0100 Subject: [PATCH 13/15] cpu: Add Broadwell-IBRS CPU model This is a variant of Broadwell with indirect branch prediction protection. The only difference between Broadwell and Broadwell-IBRS is the added "spec-ctrl" feature. The Broadwell-IBRS model in QEMU is a bit different since Broadwell got several additional features since we added it in cpu_map.xml: abm, arat, f16c, rdrand, vme, xsaveopt Adding them only to the -IBRS variant would confuse our CPU detection code.
