Subject: [PATCH v2 28/40] iommu/arm-smmu-v3: Implement mm operations
Date: Fri, 11 May 2018 20:06:29 +0100
Message-ID: <20180511190641.23008-29-jean-philippe.brucker@arm.com> (raw)
In-Reply-To: <20180511190641.23008-1-jean-philippe.brucker-5wv7dgnIgG8@public.gmane.org>

Hook mm operations to support PASID and page table sharing with the
SMMUv3:

* mm_alloc allocates a context descriptor.
* mm_free releases the context descriptor.
* mm_attach checks device capabilities and writes the context descriptor.
* mm_detach clears the context descriptor and sends required
  invalidations.
* mm_invalidate sends required invalidations.
