From: Mikko Perttunen <mperttunen@xxxxxxxxxx> Hi all, this series adds support for Host1x context isolation on Tegra234 (Orin). The difference from previous generations is that there are two IOMMUs to which engines can be attached to, resulting in having to have a set of contexts for each one. Patches should be applied in order. The first patch is needed so that the kernel doesn't attempt to use a context device attached to the wrong IOMMU when context stream IDs are present in the device tree. The other two patches have a compile time dependency. Thanks, Mikko Mikko Perttunen (3): gpu: host1x: Select context device based on attached IOMMU dt-bindings: Add Host1x context stream IDs on Tegra234 arm64: tegra: Add context isolation domains on Tegra234 arch/arm64/boot/dts/nvidia/tegra234.dtsi | 19 +++++++++++++++++++ drivers/gpu/drm/tegra/uapi.c | 2 +- drivers/gpu/host1x/context.c | 5 +++++ include/dt-bindings/memory/tegra234-mc.h | 10 ++++++++++ include/linux/host1x.h | 1 + 5 files changed, 36 insertions(+), 1 deletion(-) -- 2.37.0
