Subject: About MONITOR/MWAIT in i386 CPU model
Date: Wed, 13 Nov 2019 16:42:25 +0800	[thread overview]
Message-ID: <d52ddfd1-3d9d-6a3a-5ce9-893df96639cc@intel.com> (raw)

Hi Eduardo,

After kvm use "-overcommit cpu-pm=on" to expose MONITOR/MWAIT
(commit id 6f131f13e68d648a8e4f083c667ab1acd88ce4cd), the MONITOR/MWAIT 
feature in CPU model (phenom core2duo coreduo n270 Opteron_G3 EPYC 
Snowridge Denverton) may be unused. For example, when we boot a guest 
with Denverton cpu model, guest cannot detect MONITOR and boot with no 
warning. Should we remove this feature from some CPU model?

Tested by Guo, Xuelian <xuelian.guo@intel.com>
