[PATCH 00/20] drm/{i915, xe}: FBC cleanups + tweak fbdev stolen usage

[Ville Syrjala]

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

Here's an idea for a slightly better heuristic to answer
the "should fbdev use stolen or not?" question.

Ended up with a pile of refactoring and cleanups in
the FBC code as a result.

Ville Syrjälä (20):
  drm/i915/fbc: Extract intel_fbc_has_fences()
  drm/i915/fbc: Convert to intel_display, mostly
  drm/i915/fbc: s/_intel_fbc_cfb_stride()/intel_fbc_plane_cfb_stride()/
  drm/i915/fbc: Extract intel_fbc_max_plane_size()
  drm/i915/fbc: Extract intel_fbc_max_surface_size()
  drm/i915/fbc:
    s/intel_fbc_hw_tracking_covers_screen()/intel_fbc_surface_size_ok()/
  drm/i915/fbc: Adjust g4x+ platform checks
  drm/i915/fbc: Extract _intel_fbc_cfb_stride()
  drm/i915/fbc: s/lines/height/
  drm/i915/fbc: Reoder CFB max height platform checks
  drm/i915/fbc: Extract intel_fbc_max_cfb_height()
  drm/i915/fbc: Extract _intel_fbc_cfb_size()
  drm/i915/fbc: Extract intel_fbc_cfb_cpp()
  drm/i915/fbc: Introduce intel_fbc_preferred_cfb_size()
  drm/xe/fbdev: Fix BIOS FB vs.s stolen size checke
  drm/i915/fbdev: Extract intel_fbdev_fb_prefer_stolen()
  drm/xe/fbdev: Extract intel_fbdev_fb_prefer_stolen()
  drm/xe/fbdev: Use the same logic for fbdev stolen takever and fresh
    allocation
  drm/i915/fbdev: Adjust fbdev stolen mem usage heuristic
  drm/xe/fbdev: Adjust fbdev stolen mem usage heuristic
