Subject: [PATCH v2 5/5] KVM: arm/arm64: Advertise support for KVM_CAP_ARM_USER_IRQ
Date: Fri, 3 Feb 2017 15:56:55 +0100 [thread overview]
Message-ID: <20170203145655.15007-6-cdall@linaro.org> (raw)
In-Reply-To: <20170203145655.15007-1-cdall@linaro.org>
From: Christoffer Dall <christoffer.dall@linaro.org>
Now when we support both the virtual timer and PMU reporting interrupts
to userspace, we can advertise this support.
