From 1b7fe468b0ca6a4b47a447cf583455e445bf0246 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 27 Oct 2017 15:28:40 +0100 Subject: KVM: arm/arm64: GICv4: Handle INT command applied to a VLPI If the guest issues an INT command targetting a VLPI, let's call into the irq_set_irqchip_state() helper to make it pending on the physical side. This works just as well if userspace decides to inject an interrupt using the normal userspace API...
