Subject: [PATCH] cpu_map: Remove monitor feature from EPYC-Rome
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The feature is filtered by KVM and never automatically enabled. So even
though QEMU definition of EPYC-Rome contains this feature, the guest
won't see it. Also domain capabilities will show it as disabled for KVM
domains. Thus the feature should not really be included in our
definition of EPYC-Rome.
