[Intel-gfx] [PATCH 4/4] drm/i915: Rewrite CL/CTG L-shaped memory detection

2021-04-21 Thread Ville Syrjala
From: Ville Syrjälä Currently we try to detect a symmetric memory configurations using a magic DCC2_MODIFIED_ENHANCED_DISABLE bit. That bit is either only set on a very specific subset of machines or it just does not exist (it's not mentioned in any public chipset datasheets I've found). As it
