Subject: [PATCH V2 0/3] improve -overcommit cpu-pm=on|off
Date: Fri, 24 May 2024 13:00:14 -0700	[thread overview]
Message-ID: <20240524200017.150339-1-zide.chen@intel.com> (raw)

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.

V2:
- [PATCH 1]: took Thomas' suggestion for more generic fix
- [PATCH 2/3]: no changes

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()
