The change to the arm-smmu driver should be omitted if Robin Murphy's IOMMU bus cleanup series is merged. *** New in v6: Rebased on 5.19-rc3 (-next is too broken) Added patch to fix TRANSCFG offset on NVDEC. *** *** New in v5: Rebased Renamed host1x_context to host1x_memory_context Small change in DRM side client driver ops to reduce churn with some upcoming changes Add NVDEC support *** *** New in v4: Addressed review comments. See individual patches. *** *** New in v3: Added device tree bindings for new property. *** *** New in v2: Added support for Tegra194 Use standard iommu-map property instead of custom mechanism *** This series adds support for Host1x 'context isolation'. Since when programming engines through Host1x, userspace can program in any addresses it wants, we need some way to isolate the engines' memory spaces. Traditionally this has either been done imperfectly with a single shared IOMMU domain, or by copying and verifying the programming command stream at submit time (Host1x firewall). Since Tegra186 there is a privileged (only usable by kernel) Host1x opcode that allows setting the stream ID sent by the engine to the SMMU. So, by allocating a number of context banks and stream IDs for this purpose, and using this opcode at the beginning of each job, we can implement isolation. Due to the limited number of context banks only each process gets its own context, and not each channel. This feature also allows sharing engines among multiple VMs when used with Host1x's hardware virtualization support - up to 8 VMs can be configured with a subset of allowed stream IDs, enforced at hardware level. To implement this, this series adds a new host1x context bus, which will contain the 'struct device's corresponding to each context bank / stream ID, changes to device tree and SMMU code to allow registering the devices and using the bus, as well as the Host1x stream ID programming code and support in TegraDRM.
