[PATCH 0/3] improve -overcommit cpu-pm=on|off

Posted by Zide Chen 6 months, 1 week ago

Currently, if running "-overcommit cpu-pm=on" on hosts that don't
have MWAIT support, the MWAIT/MONITOR feature is advertised to the
guest and executing MWAIT/MONITOR on the guest triggers #UD.

Zide Chen (3):
  vl: Allow multiple -overcommit commands
  target/i386: call cpu_exec_realizefn before x86_cpu_filter_features
  target/i386: Move host_cpu_enable_cpu_pm into kvm_cpu_realizefn()
