Subject: [PATCH 3/3] drivers/vfio: Allow type-1 IOMMU instantiation on top of an ARM SMMUv3
Date: Fri, 8 May 2015 19:00:46 +0100 [thread overview]
Message-ID: <1431108046-9675-4-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1431108046-9675-1-git-send-email-will.deacon-5wv7dgnIgG8@public.gmane.org>
The ARM SMMUv3 driver is compatible with the notion of a type-1 IOMMU in
VFIO.
This patch allows VFIO_IOMMU_TYPE1 to be selected if ARM_SMMU_V3=y.
