Subject: [Intel-gfx] [CI 1/3] drm/i915/gt: Move move context layout registers and offsets to lrc_reg.h
Date: Wed,  9 Dec 2020 23:36:16 +0000	[thread overview]
Message-ID: <20201209233618.4287-1-chris@chris-wilson.co.uk> (raw)

Cleanup intel_lrc.h by moving some of the residual common register
definitions into intel_lrc_reg.h, prior to rebranding and splitting off
the submission backends.

v2: keep the SCHEDULE enum in the old file, since it is specific to the
gvt usage of the execlists submission backend (John)
