This patch set is implementing eDP1.5 Panel Replay for Intel hw. Also
Region Early Transport information is added into debugfs interface
and patch to disable Region Early Transport by default is reverted as
it is needed by eDP Panel Replay.
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 (19):
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/i915/psr: Add Panel Replay support to intel_psr2_config_et_valid
drm/i915/alpm: Make alpm support checks non-static
