This patch set is implementing eDP1.5 Panel Replay for Intel hw and enabling it on LunarLake HW when eDP1.5 panel is available. Patches are tested using two differenet eDP1.5 panel models. IGT modifications for testing are under review and available here: https://patchwork.freedesktop.org/series/133866/ v9: - rebase (part of v8 set is merged) v8: - series reordered to ease merging subset - wa 16021440873 modified - Fix port clock usage in AUX Less wake time calculation - Disable PSR/Panel Replay on sink side for PSR only v7: - fix improper SU area width - writing wrong register in Wa 16021440873 - disable Panel Replay if psr_enable is set != -1 - perfrom ALPM check for Panel Replay Full Frame update - printout why Panel Replay is disabled 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 - printout debug info in case Panel Replay is prevented 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 (11): drm/i915/psr: Check panel ALPM capability for eDP Panel Replay drm/i915/psr: Inform Panel Replay source support on eDP as well drm/i915/psr: enable sink for eDP1.5 Panel Replay drm/i915/psr: Check panel Early Transport capability for eDP PR 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/alpm: Make crtc_state as const in intel_alpm_compute_params drm/i915/psr: Perform psr2 checks related to ALPM for Panel Replay drm/i915/psr: Perform scanline indication check for Panel Replay as well drm/i915/psr: Check Early Transport for Panel Replay as well drm/i915/psr: Modify dg2_activate_panel_replay to support eDP drivers/gpu/drm/i915/display/intel_alpm.c | 9 +- drivers/gpu/drm/i915/display/intel_alpm.h | 2 +- drivers/gpu/drm/i915/display/intel_psr.c | 163 +++++++++++++++++----- 3 files changed, 137 insertions(+), 37 deletions(-) -- 2.34.1
