[Intel-gfx] [PATCH 0/6] drm/i915/dpt: Fix DPT+shmem combo and add i915.enable_dpt modparam

[Ville Syrjala]

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

Avoid the shrinker evicting the DPT during hibernate and
causing an oops. This might also fix DPT induced display faults
during high memory pressure (though still don't have a real
theory how that could actually happen).

Also add a i915.enable_dpt modparam to disable DPT usage via
the chicken bit. This can be useful when trying to debug suspected
DPT issues.

Ville Syrjälä (6):
  drm/i915/dpt: Treat the DPT BO as a framebuffer
  drm/i915/dpt: Only do the POT stride remap when using DPT
  drm/i915/dpt: Introduce HAS_DPT()
  drm/i915: Add PLANE_CHICKEN registers
  drm/i915/dpt: Add a modparam to disable DPT via the chicken bit
  drm/i915: Move PLANE_BUG_CFG bit definitons to the correct place
