From 55b1b753dff022dcc95123bed35946b4977d31fa Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Tue, 23 Jun 2015 09:10:51 +0200 Subject: [PATCH] s390x/gdb: synchronize cpu state after modifying acrs Whenever we touch the access control registers, we have to make sure that the values will make it into kvm. Otherwise the change will simply be lost. When synchronizing qemu and kvm, a normal KVM_PUT_RUNTIME_STATE does not take care of these registers. Let's simply trigger a KVM_PUT_FULL_STATE sync, so the values will directly be written to kvm. The performance overhead can be ignored and this is much cleaner than manually writing these registers to kvm via our two supported ways.
