I did some light testing with our anvil (Vulkan) and iris (OpenGL)
Mesa drivers after applying these patches on top of drm-tip tagged
intel/CI_DRM_11574. All the unit tests that I tried passed. I also ran
the gl_manhattan31 benchmark which used the compute engine for iris
compute shader ops.

Now that the necessary GuC-based hardware workarounds have landed, we're
finally ready to actually enable compute engines for use by userspace.
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 ua
