From 2eb12fe44228a9aecc21246c16d55c40bc182e63 Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Tue, 20 Jul 2021 16:20:13 -0700 Subject: [PATCH] drm/i915/gt: rename legacy engine->hw_id to engine->gen6_hw_id 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.
