-Subject: [PATCH] memory: tegra: Remove GPU from DRM IOMMU group
-Date: Tue, 1 Sep 2020 17:32:48 +0200
-Message-Id: <20200901153248.1831263-1-thierry.reding@gmail.com>
-X-Mailer: git-send-email 2.28.0
-MIME-Version: 1.0
-Sender: linux-tegra-owner@vger.kernel.org
-Precedence: bulk

-From: Thierry Reding <treding@nvidia.com>
-
-Commit 63a613fdb16c ("memory: tegra: Add gr2d and gr3d to DRM IOMMU
-group") added the GPU to the DRM IOMMU group, which doesn't make any
-sense. This causes problems when Nouveau tries to attach to the SMMU
-and causes it to fall back to using the DMA API.
-
-Remove the GPU from the DRM groups to restore the old behaviour. The
-GPU should always have its own IOMMU domain to make sure it can map
-buffers into contiguous chunks (for big page support) without getting
-in the way of mappings from the DRM group.
-
-Fixes: 63a613fdb16c ("memory: tegra: Add gr2d and gr3d to DRM IOMMU group")
