From 6e84e0e0677281b4e7fc634c7e9d085fbcf41b10 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 8 Jun 2015 16:13:30 +0100 Subject: KVM: arm/arm64: vgic: Add vgic_{get,set}_phys_irq_active In order to control the active state of an interrupt, introduce a pair of accessors allowing the state to be set/queried. This only affects the logical state, and the HW state will only be applied at world-switch time.
