This patch set is implementing eDP1.5 Panel Replay for Intel hw. Patch
to disable Region Early Transport by default is reverted as it is
needed by eDP Panel Replay.
Patches 1 - 14 are fixes and clean-ups for DP2.0 Panel Replay found while testing with eDP1.5 panel. Patches 15 - 26 are implementing Panel Replay eDP.
v6:
- fix and rework sink enable
- rework checking vblank length for LunarLake and Panel Replay
- reorder patches
v5:
- use psr->su_region_et_enabled instead of psr2_su_region_et_valid
- do not check Vblank >= PSR2_CTL Block Count Number for Panel Replay
v4:
- add some patch from "Panel Replay fixes" set here
- check 128b/132b encoding and HDCP enable
- use intel_alpm_aux_wake_supported instead of local variable
v3:
- commit message modifications
- s/intel_psr_psr_mode/intel_psr_print_mode/
- remove extra space from "PSR mode: disabled"
- do not allow eDP Panel Replay when using 128b/132b encoding
- do not allow eDP Panel Replay when HDCP is enabled
v2:
- printout "Selective Update enabled (Early Transport)" instead of
"Selective Update Early Transport enabled"
- ensure that fastset is performed when the disable bit changes
Jouni Högander (26):
drm/i915/alpm: Do not use fast_wake_lines for aux less wake time
drm/i915/alpm: Write also AUX Less Wake lines into ALPM_CTL
drm/i915/display: Take panel replay into account in vsc sdp unpacking
drm/i915/display: Skip Panel Replay on pipe comparison if no active
planes
drm/display: Add missing Panel Replay Enable SU Region ET bit
drm/i915/psr: Split enabling sink for PSR and Panel Replay
drm/i915/alpm: Make alpm support checks non-static

variable
drm/i915/psr: Add Panel Replay support to intel_psr2_config_et_valid
drm/i915/psr: Print Panel Replay status instead of frame lock status
drm/i915/psr: Move vblank length check to separate function

check
drm/i915/psr: Check vblank against IO buffer wake time on Lunarlake
dmr/i915/psr: Wake time is aux less wake time for Panel Replay

drm/i915/psr: Perfrom psr2 checks related to ALPM for Panel Replay
drm/i915/psr: Add Panel Replay compute_config helper
drm/i915/psr: 128b/132b Panel Replay is not supported on eDP
drm/i915/psr: HW will not allow PR on eDP when HDCP enabled
drm/i915/psr: Check Early Transport for Panel Replay as well
drm/i915/psr: Modify dg2_activate_panel_replay to support eDP
drm/i915/psr: Add new debug bit to disable Panel Replay
