The timer work is only scheduled for a VCPU when that VCPU is blocked. This means we only need to wake it up, not kick (IPI) it. While calling kvm_vcpu_kick() would just do the wake up, and not kick, anyway, let's change this to avoid request-less vcpu kicks, as they're generally not a good idea (see "Request-less VCPU Kicks" in Documentation/virtual/kvm/vcpu-requests.rst) Signed-off-by: Andrew Jones <drjones@xxxxxxxxxx> --- virt/kvm/arm/arch_timer.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/virt/kvm/arm/arch_timer.c b/virt/kvm/arm/arch_timer.c index 5976609ef27c..c9cd56f39b1e 100644 --- a/virt/kvm/arm/arch_timer.c +++ b/virt/kvm/arm/arch_timer.c @@ -95,7 +95,7 @@ static void kvm_timer_inject_irq_work(struct work_struct *work) * If the vcpu is blocked we want to wake it up so that it will see * the timer has expired when entering the guest. */ - kvm_vcpu_kick(vcpu); + swake_up(kvm_arch_vcpu_wq(vcpu)); } static u64 kvm_timer_compute_delta(struct arch_timer_context *timer_ctx) -- 2.9.3
