That is my original proposal solution of this bug. However, what I concern
after more think is since kvm_lapic_find_highest_irr will not clear
irr, if the intr will be injected by kvm_86_ops->hwapic_irr_update(vcpu,
kvm_lapic_find_highest_irr(vcpu)) which called by vcpu_enter_guest() again?
Any idea, Paolo?
The processor should do that when it does the virtual interrupt
delivery. It will do (29.2.2):
Vector := RVI;
VISR[Vector] := 1;
SVI := Vector;
VIRR[Vector] := 0;
If VIRR not empty
then RVI := highest index of bit set in VIRR
else RVI := 0
Fi;
deliver interrupt with Vector through IDT;
Please post a patch, so we can reason on it better.
Paolo
