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
should work on PTL now
v3: Rebase due to DSB GOSUB stuff getting merged
Try to fix PKG_C_LATENCY
Ignore INT_VECTOR when opther PIPEDMC interrupt are present
Ville Syrjälä (12):
drm/i915/dsb: Use intel_dsb_ins_align() in intel_dsb_align_tail()
drm/i915/dsb: Provide intel_dsb_head() and intel_dsb_size()
drm/i915/dsb: Introduce intel_dsb_exec_time_us()
drm/i915: Set PKG_C_LATENCY.added_wake_time to 0
drm/i915: Try to program PKG_C_LATENCY more correctly
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
