Avi, Marcello,
Newer (guest) kernels use sigp sense running in their spinlock
implementation to check if the other cpu is running before yielding
the processor. This revealed some wrong guest settings, causing
unnecessary exits for every sigp sense running.
Applied, thanks.
void kvm_arch_vcpu_destroy(struct kvm_vcpu *vcpu)
{
VCPU_EVENT(vcpu, 3, "%s", "free cpu");
+ clear_bit(63 - vcpu->vcpu_id, (unsigned long
*)&vcpu->kvm->arch.sca->mcn);
if (vcpu->kvm->arch.sca->cpu[vcpu->vcpu_id].sda ==
(__u64) vcpu->arch.sie_block)
vcpu->kvm->arch.sca->cpu[vcpu->vcpu_id].sda = 0;
Unrelated, do these VCPU_EVENTs want to become ftrace tracepoints?
