All of the "under-the-hood" heavy lifting already landed a while back in other series so all that remains now is to add I915_ENGINE_CLASS_COMPUTE to the uapi enum and add the CCS engines to the engine lists for the Xe_HP SDV and DG2. Userspace (both Mesa and compute drivers) are linked in the ABI patch. Existing IGT tests (e.g., i915_hangman) provide test coverage for general engine behavior since compute engines should follow the same general rules as other engines. We've also recently added some additional subtests like igt@gem_reset_stats@shared-reset-domain to cover the user-visible impacts of the compute engines sharing the same hardware reset domain as the render engine.
