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") -Reported-by: Matias Zuniga <matias.nicolas.zc@gmail.com> -Signed-off-by: Thierry Reding <treding@nvidia.com> -Reviewed-by: Dmitry Osipenko <digetx@gmail.com> ---- - drivers/memory/tegra/tegra124.c | 1 - - 1 file changed, 1 deletion(-) - -diff --git a/drivers/memory/tegra/tegra124.c b/drivers/memory/tegra/tegra124.c -index 493b5dc3a4b3..0cede24479bf 100644 ---- a/drivers/memory/tegra/tegra124.c -+++ b/drivers/memory/tegra/tegra124.c -@@ -957,7 +957,6 @@ static const struct tegra_smmu_swgroup tegra124_swgroups[] = { - static const unsigned int tegra124_group_drm[] = { - TEGRA_SWGROUP_DC, - TEGRA_SWGROUP_DCB, -- TEGRA_SWGROUP_GPU, - TEGRA_SWGROUP_VIC, - }; - |
