O-Subject: [RHEL8 qemu-kvm PATCH v3 2/2] hw/s390x/s390-virtio-ccw: Add machine types for RHEL8.0.0
Bugzilla: 1656510
RH-Acked-by: Cornelia Huck <cohuck@redhat.com>
RH-Acked-by: Thomas Huth <thuth@redhat.com>
RH-Acked-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1656510
Upstream: n/a (downstream only)
Branch: rhel8/master-3.1.0
Downstream s390x machine types for the Advanced Virtualization module.
s390mc->hpage_1m_allowed has to stay enabled for the rhel7.6.0 machine,
because RHEL 8 supports huge pages. For RHEL 7.6-alt, this is fenced
using a different mechanism (bail out if huge pages are used right from
the start).
