[Freedreno] [PATCH 2/2] arm64: dts: qcom: sm8250: Enable per-process page tables.

2022-06-14 Thread Emma Anholt
This is an SMMU for the adreno gpu, and adding this compatible lets the driver use per-fd page tables, which are required for security between GPU clients. Signed-off-by: Emma Anholt --- Tested with a full deqp-vk run on RB5, which did involve some iommu faults.
