From 13209ad0395c4de7fa48108b1dac72e341d5c089 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Fri, 28 Dec 2018 09:33:35 +0100 Subject: KVM: s390: add MSA9 to cpumodel This enables stfle.155 and adds the subfunctions for KDSA. Bit 155 is added to the list of facilities that will be enabled when there is no cpu model involved as MSA9 requires no additional handling from userspace, e.g. for migration. Please note that a cpu model enabled user space can and will have the final decision on the facility bits for a guests.
