[Ville Syrjala]

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

Initial stab at implementing the PIPEDMC based flip queue.
Briefly smoke tested on LNL, not much more.

Still has quite a few warts..

v2: cleaned up a few of the warts at least
    whould work on PTL now

Ville Syrjälä (13):
  drm/i915/dsb: Extract intel_dsb_ins_align()
  drm/i915/dsb: Use intel_dsb_ins_align() in intel_dsb_align_tail()
  drm/i915/dsb: Extract assert_dsb_tail_is_aligned()
  drm/i915/dsb: Extract intel_dsb_{head,tail}()
  drm/i915/dsb: Provide intel_dsb_head() and intel_dsb_size()
  drm/i915/dsb: Introduce intel_dsb_exec_time_us()
  drm/i915/dmc: Define flip queue related PIPEDMC registers
  drm/i915/flipq: Provide the nuts and bolts code for flip queue
  drm/i915/flipq: Implement flip queue based commit path
  drm/i915/flipq: Implement Wa_18034343758
  drm/i915/flipq: Implement Wa_16018781658 for LNL-A0
  drm/i915/flipq: Add intel_flipq_dump()
  drm/i915/flipq: Enable flipq by default for testing
