Subject: [Intel-gfx] [PATCH 3/4] drm/i915/gt: rename legacy engine->hw_id to engine->gen6_hw_id
Date: Tue, 20 Jul 2021 16:20:13 -0700 [thread overview]
Message-ID: <20210720232014.3302645-4-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20210720232014.3302645-1-lucas.demarchi@intel.com>
We kept adding new engines and for that increasing hw_id unnecessarily:
it's not used since GRAPHICS_VER == 8. Prepend "gen6" to the field and
try to pack it in the structs to give a hint this field is actually not
used in recent platforms.
