Re: [PATCH 1/2] drm/i915: Store the BIT(engine->id) as the engine's mask

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




On 02/03/2019 10:06, Chris Wilson wrote:
In the next patch, we are introducing a broad virtual engine to encompass
multiple physical engines, losing the 1:1 nature of BIT(engine->id). To
reflect the broader set of engines implied by the virtual instance, lets
store the full bitmask.

v2: Use intel_engine_mask_t (s/ring_mask/engine_mask/)
v3: Tvrtko voted for moah churn so teach everyone to not mention ring
and use $class$instance throughout.

I wasn't suggesting renaming the engine id enums, but on the other hand it is nicer to have VCS0, VCS1,.. instead of VCS, VCS2, VCS3,...

So ack from me. And since I read it all almost r-b if not the unrelated error state hunk and more importantly reservations about bit definition names from i915_reg.h.
