Subject: [PATCH v2 11/12] target/arm/kvm: spe: Enable userspace irqchip support.
Date: Tue,  8 Sep 2020 08:13:29 +0000	[thread overview]
Message-ID: <6aaa406b824d0c427acbc3f3abfbbe841f3bb93c.1599549462.git.haibo.xu@linaro.org> (raw)
In-Reply-To: <cover.1599549462.git.haibo.xu@linaro.org>

Since the current kernel patches haven't enabled the
userspace irqchip support, this patch is not verified yet!
