[PATCH v2 00/16] drm/i915: Introduce 'fb_pin' parent interface

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

Abstract the fb pin/unpin stuff under a new 'fb_pin' parent
interface. The interface is fairly low level so that the i915/xe
side doesn't need access to any display specific data structures.

There are perhaps some needless extra layers on the i915/xe side
afterwards, but we can clean those out later. There are also some
rough corners left in the initial fb code, but I'll be following
up with a separate series to fix/clean up that whole thing.

v2: Rebase and pimp some commit messages
    Fix the vma reuse gtt view memcmp()

Ville Syrjälä (16):
  drm/i915: Introduce intel_parent_fb_pin_get_map()
  drm/i915: Move intel_fb_pin_params to the parent interface
  drm/i915: Move the i915_dpt_offset()==0 assert
  drm/i915: Reorganize intel_plane_pin_fb() a bit
  drm/i915: Introduce i915_fb_pin_dpt_(un)pin()
  drm/i915: Introduce i915_fb_pin_ggtt_(un)pin()
  drm/xe: Move the FORCE_WC assert into __xe_pin_fb_vma()
  drm/xe: Kill the fbdev vma reuse hack
  drm/xe: Reorganize intel_plane_pin_fb() a bit
  drm/xe: Introduce xe_fb_pin_dpt_(un)pin()
  drm/xe: Introduce xe_fb_pin_ggtt_(un)pin()
  drm/xe: Restructure reuse_vma()
  drm/i915: Introduce the main fb_pin parent interface
  drm/i915/fbdev: Use intel_parent_fb_pin_ggtt_(un)pin()
  drm/xe: Use xe_fb_pin_ggtt_pin() for the initial FB pin
  drm/i915: Consolidate the intel_plane_(un)pin_fb() implementations
