Date: Mon, 20 Jul 2020 09:40:39 -0600 From: Jordan Crouse <jcrouse@...eaurora.org> To: linux-arm-msm@...r.kernel.org Cc: Robin Murphy <robin.murphy@....com>, Bjorn Andersson <bjorn.andersson@...aro.org>, Will Deacon <will@...nel.org>, freedreno@...ts.freedesktop.org, iommu@...ts.linux-foundation.org, Sai Prakash Ranjan <saiprakash.ranjan@...eaurora.org>, Joerg Roedel <joro@...tes.org>, linux-kernel@...r.kernel.org Subject: [PATCH v10 05/13] iommu: Add a domain attribute to get/set a pagetable configuration Add domain attribute DOMAIN_ATTR_PGTABLE_CFG. This will be used by arm-smmu to share the current pagetable configuration with the leaf driver and to allow the leaf driver to set up a new pagetable configuration under certain circumstances.
