[Freedreno] [RFC PATCH v1 3/3] drm/msm: Improve the a6xx page fault handler

Use the new adreno-smmu-priv fault info function to get more SMMU debug registers and print the current TTBR0 to debug per-instance pagetables and figure out which GPU block generated the request. Signed-off-by: Jordan Crouse --- drivers/gpu/drm/msm/adreno/a5xx_gpu.c | 4 +- drivers/gpu/drm/ms

[Freedreno] [RFC PATCH v1 0/3] iommu/arm-smmu: adreno-smmu page fault handling

This is an RFC to add an Adreno GPU specific handler for pagefaults. The first patch starts by wiring up report_iommu_fault for arm-smmu. The next patch adds a adreno-smmu-priv function hook to capture a handful of important debugging registers such as TTBR0, CONTEXTIDR, FSYNR0 and others. This is

[Freedreno] [PATCH] drm/msm: dsi: Constify dsi_host_ops

The only usage of dsi_host_ops is to assign its address to the ops field in the mipi_dsi_host struct, which is a const pointer. Make it const to allow the compiler to put it in read-only memory. Signed-off-by: Rikard Falkeborn --- drivers/gpu/drm/msm/dsi/dsi_host.c | 2 +- 1 file changed, 1 inse
