This patch set is adding missing configuration to have Panel Replay and Adaptive Sync enabled simultaneously. Also some issues identified while debugging are fixed:
1. Source PORT ALPM configuration has to made during modeset. 2. PHY_CMN1_CONTROL is not written according to HAS document 3. Wrong register field definitions for PORT_ALPM_LFPS_CTL. Patches are tested on LunarLake and PantheLake using our reference panel supporting Adaptive Sync and Panel Replay. EMP_AS_SDP_TL is currently missing completely from drm-tip. There is a patch for that which is needed if testing these patches: https://patchwork.freedesktop.org/series/148421/ Otherwise "PSR idle timeout" errors are seen while testing. v3: - comment about DP2.1 corrected as DP2.1a - referring patch removed from commit message v2: - rework Panel Replay DPCD register definitions - do not use hardcoded indices while accessing intel_dp->pr_dpcd - ensure ALPM registers are not written on platform where they do not exist - remove kerneldoc comments Jouni Högander (12): drm/panelreplay: Panel Replay capability DPCD register definitions drm/dp: Add Panel Replay capability bits from DP2.1 specification drm/i915/psr: Read all Panel Replay capability registers from DPCD drm/i915/alpm: Add PR_ALPM_CTL register definitions drm/i915/alpm: Write PR_ALPM_CTL register drm/i915/psr: Add interface to check if AUXLess ALPM is needed by PSR drm/i915/alpm: Add new interface to check if AUXLess ALPM is used drm/i915/alpm: Move port alpm configuration drm/i915/display: Add PHY_CMN1_CONTROL register definitions drm/i915/display: Add function to configure LFPS sending drm/i915/psr: Fix using wrong mask in REG_FIELD_PREP drm/i915/psr: Do not disable Panel Replay in case VRR is enabled drivers/gpu/drm/i915/display/intel_alpm.c | 72 +++++++++++++------ drivers/gpu/drm/i915/display/intel_alpm.h | 4 ++ drivers/gpu/drm/i915/display/intel_cx0_phy.c | 32 +++++++++ drivers/gpu/drm/i915/display/intel_cx0_phy.h | 2 + .../gpu/drm/i915/display/intel_cx0_phy_regs.h | 3 + drivers/gpu/drm/i915/display/intel_ddi.c | 12 ++++ .../drm/i915/display/intel_display_types.h | 4 +- drivers/gpu/drm/i915/display/intel_psr.c | 44 +++++++----- drivers/gpu/drm/i915/display/intel_psr.h | 2 + drivers/gpu/drm/i915/display/intel_psr_regs.h | 14 +++- include/drm/display/drm_dp.h | 18 +++-- 11 files changed, 163 insertions(+), 44 deletions(-) -- 2.43.0
