From 3dbbdf78636e66094d82c4df496c54ff6ae46e31 Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Wed, 1 Feb 2017 12:51:52 +0100 Subject: KVM: arm/arm64: Report PMU overflow interrupts to userspace irqchip When not using an in-kernel VGIC, but instead emulating an interrupt controller in userspace, we should report the PMU overflow status to that userspace interrupt controller using the KVM_CAP_ARM_USER_IRQ feature.
