From mboxrd@z Thu Jan 1 00:00:00 1970 From: marc.zyngier@arm.com (Marc Zyngier) Date: Wed, 8 Jul 2015 18:56:37 +0100 Subject: [PATCH v2 05/10] KVM: arm/arm64: vgic: Relax vgic_can_sample_irq for edge IRQs In-Reply-To: <1436378202-20224-1-git-send-email-marc.zyngier@arm.com> References: <1436378202-20224-1-git-send-email-marc.zyngier@arm.com> Message-ID: <1436378202-20224-6-git-send-email-marc.zyngier@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org We only set the irq_queued flag for level interrupts, meaning that "!vgic_irq_is_queued(vcpu, irq)" is a good enough predicate for all interrupts. This will allow us to inject edge HW interrupts, for which the state ACTIVE+PENDING is not allowed.
