From 0d13ff22c572978cbef5e0b9ad81143178315bf6 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Mon, 10 Dec 2018 19:25:34 +0000 Subject: [PATCH 06/13] i386: Add "stibp" flag name RH-Author: Eduardo Habkost Message-id: <20181210192534.21567-2-ehabkost@redhat.com> Patchwork-id: 83359 O-Subject: [RHEL8/rhel qemu-kvm PATCH 1/1] i386: Add "stibp" flag name Bugzilla: 1639446 RH-Acked-by: Daniel P. Berrange RH-Acked-by: Dr. David Alan Gilbert RH-Acked-by: Paolo Bonzini The STIBP flag may be supported by the host KVM module, so QEMU can allow it to be configured manually, and it can be exposed to guests when using "-cpu host". No additional migration code is required because the whole contents of spec_ctrl is already migrated in the "cpu/spec_ctrl" section.
