It is also fixing several exisiting issues in current panel replay implementation: Several needed functions are not executed for panel replay Ensure link training follows enabling panel replay on sink side Do not update phy power state for panel replay. Do not apply workarounds not applicable for panel replay Do not write registers/bits not applicable for panel replay v5: - do not use PSR2_STATUS for PSR1 v4: - do not rename intel_psr_enabled - do not add sel_update_et_enabled into struct intel_psr v3: - do not disable panel replay by default - set has_psr for panel replay as well - enable sink before link training - do not apply all PSR workarounds for panel replay - do not write/read registers/bits not applicable for panel replay - use psr bit definitions in granularity configuration as well - goto unsupported instead of return when global enabled check fails - update module parameter descriptions. v2: - make psr pause/resume to work for panel replay as well Jouni Högander (19): drm/i915/psr: Add some documentation of variables used in psr code drm/i915/psr: Set intel_crtc_state->has_psr on panel replay as well drm/i915/psr: Intel_psr_pause/resume needs to support panel replay drm/i915/psr: Do not update phy power state in case of non-eDP panel replay drm/i915/psr: Check possible errors for panel replay as well drm/i915/psr: Do not write registers/bits not applicable for panel replay drm/i915/psr: Call intel_psr_init_dpcd in intel_dp_detect drm/i915/psr: Unify panel replay enable/disable sink drm/i915/psr: Panel replay has to be enabled before link training drm/i915/psr: Rename has_psr2 as has_sel_update drm/i915/psr: Rename psr2_enabled as sel_update_enabled drm/panelreplay: dpcd register definition for panelreplay SU drm/i915/psr: Detect panel replay selective update support drm/i915/psr: Modify intel_dp_get_su_granularity to support panel replay drm/i915/psr: Panel replay uses SRD_STATUS to track it's status drm/i915/psr: Do not apply workarounds in case of panel replay drm/i915/psr: Update PSR module parameter descriptions drm/i915/psr: Split intel_psr2_config_valid for panel replay drm/i915/psr: Add panel replay sel update support to debugfs interface .../drm/i915/display/intel_crtc_state_dump.c | 10 +- drivers/gpu/drm/i915/display/intel_ddi.c | 11 +- drivers/gpu/drm/i915/display/intel_display.c | 12 + .../drm/i915/display/intel_display_params.c | 5 +- .../drm/i915/display/intel_display_types.h | 5 +- drivers/gpu/drm/i915/display/intel_dp.c | 13 +- drivers/gpu/drm/i915/display/intel_fbc.c | 5 +- drivers/gpu/drm/i915/display/intel_hdmi.c | 3 +- drivers/gpu/drm/i915/display/intel_psr.c | 420 ++++++++++++------ drivers/gpu/drm/i915/display/intel_psr.h | 5 + include/drm/display/drm_dp.h | 6 + 11 files changed, 343 insertions(+), 152 deletions(-)
