Subject: [PATCH 24/37] iommu/arm-smmu-v3: Add SVA feature checking
Date: Mon, 12 Feb 2018 18:33:39 +0000	[thread overview]
Message-ID: <20180212183352.22730-25-jean-philippe.brucker@arm.com> (raw)
In-Reply-To: <20180212183352.22730-1-jean-philippe.brucker-5wv7dgnIgG8@public.gmane.org>

Aggregate all sanity-checks for sharing CPU page tables with the SMMU
under a single ARM_SMMU_FEAT_SVA bit. For PCIe SVA, users also need to
check FEAT_ATS and FEAT_PRI. For platform SVM, they will most likely have
to check FEAT_STALLS.
