Subject: [PATCH v5 18/18] svm: Allow AVIC with in-kernel irqchip mode
Date: Thu, 14 Nov 2019 14:15:20 -0600	[thread overview]
Message-ID: <1573762520-80328-19-git-send-email-suravee.suthikulpanit@amd.com> (raw)
In-Reply-To: <1573762520-80328-1-git-send-email-suravee.suthikulpanit@amd.com>

Once run-time AVIC activate/deactivate is supported, and EOI workaround
for AVIC is implemented, we can remove the kernel irqchip split mode
requirement for AVIC.

Hence, remove the check for irqchip split mode when enabling AVIC.
