Revision 0361bdfddca20c8855ea3bdbbbc9c999912b10ff authored by Wanpeng Li on 18 April 2022, 07:42:32 UTC, committed by Paolo Bonzini on 21 April 2022, 17:16:14 UTC
MSR_KVM_POLL_CONTROL is cleared on reset, thus reverting guests to host-side polling after suspend/resume. Non-bootstrap CPUs are restored correctly by the haltpoll driver because they are hot-unplugged during suspend and hot-plugged during resume; however, the BSP is not hotpluggable and remains in host-sde polling mode after the guest resume. The makes the guest pay for the cost of vmexits every time the guest enters idle. Fix it by recording BSP's haltpoll state and resuming it during guest resume.
