Looks okay. But one more thing is needed:
https://cgit.freedesktop.org/~tursulin/drm-intel/commit/?h=media&id=38266bfe99469de9e13774a13fa641c377988c67
drm/i915: Allow SSEU configuration to be set on virtual engine
/* Only render engine supports RPCS configuration. */
- if (engine->class != RENDER_CLASS)
+ if (engine->class != RENDER_CLASS &&
+ !(engine->flags & I915_ENGINE_IS_VIRTUAL &&
+ ctx->engines[1]->class == RENDER_CLASS))
return -ENODEV;
A virtual engine composed of RCS engines would have
engine->class == RENDER_CLASS.
So it's just the engine->id BUG_ON that needs lifting?
If so then yes. Must be a recent change since I was sure the class was
set to other before.
Regards,
Tvrtko
