[PATCH v4] drm/i915/uncore: Use GT message helpers in uncore

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

 



From: John Harrison <John.C.Harrison@xxxxxxxxx>

Uncore is really part of the GT. So use the GT specific debug/error
message helpers so as to get the GT index in the prints.
