Subject: [PATCH 0/4] drm/i915: Fix older platforms
Date: Wed, 21 Apr 2021 18:33:57 +0300	[thread overview]
Message-ID: <20210421153401.13847-1-ville.syrjala@linux.intel.com> (raw)

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Fix a div-by-zero on gen2, and make the L-shaped memory detection
actually work on cl/ctg. Atm the SWIZZLE_UNKNOWN stuff just trips
some GEM_BUG_ONs. This doesn't fix those but since I populate all
my memory channels symmetrically I get to avoid the GEM_BUG_ONs
by correctly detecting that I don't have an L-shaped memory
configuration.

Ville Syrjälä (4):
  drm/i915: Avoid div-by-zero on gen2
  drm/i915: Read C0DRB3/C1DRB3 as 16 bits again
  drm/i915: Give C0DRB3/C1DRB3 a _BW suffix
  drm/i915: Rewrite CL/CTG L-shaped memory detection
