From 0347ab84698e668a8da5ce05c3ad4e1d6e553456 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Wed, 13 Sep 2017 15:24:11 +0200 Subject: [PATCH] s390x: allow cpu hotplug via device_add E.g. the following now works: device_add host-s390-cpu,id=cpu1,core-id=1 The system will perform the same checks as when using cpu_add: - If the core_id is already in use - If the next sequential core_id isn't used - If core-id >= max_cpu is specified In addition, mixed CPU models are checked. E.g. if starting with -cpu host and trying to hotplug "qemu-s390-cpu": "Mixed CPU models are not supported on s390x."
