And I'll call the intel_psr2_program_trans_man_trk_ctl() after calling intel_psr_update(). And because the psr structure has moved into intel_dp, we need to pass intel_dp to intel_psr2_program_trans_man_trk_ctl() as an input parameter. And I did not want to add an additional loop traversal for searching intel_dp. so I decided to use the existing code for searching intel_dp. intel_encoder's update_pipe callback traverses intel_encoders. And intel_encoder's update_pipe callback would be called just before commit_pipe_config(). that is why I added the code here. [function call flow] intel_update_crtc() => intel_encoders_update_pipe() => intel_encoder->update_pipe() => intel_ddi_update_pipe_dp(); => commit_pipe_config() => intel_psr2_program_trans_man_trk_ctl() > > intel_psr_update(intel_dp, crtc_state, conn_state);

It is a preliminary work for supporting multiple EDP PSR and DP PanelReplay. And it refactors singleton PSR to Multi Transcoder supportable PSR. And this moves and renames the i915_psr structure of drm_i915_private's to intel_dp's intel_psr structure. It also causes changes in PSR interrupt handling routine for supporting multiple transcoders. But it does not change the scenario and timing of enabling and disabling PSR. And it not support multiple pipes with a single transcoder PSR case yet. v2: Fix indentation and add comments v3: Remove Blank line v4: Rebased v5: Rebased and Addressed Anshuman's review comment. - Move calling of intel_psr_init() to intel_dp_init_connector() v6: Address Anshuman's review comments - Remove wrong comments and add comments for a limit of supporting of a single pipe PSR v7: Update intel_psr_compute_config() for supporting multiple transcoder PSR on BDW+ v8: Address Anshuman's review comments - Replace DRM_DEBUG_KMS with drm_dbg_kms() / DRM_WARN with drm_warn() v9: Fix commit message v10: Rebased Signed-off-by: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com> Cc: Anshuman Gupta <anshuman.gupta@intel.com> Reviewed-by: Anshuman Gupta <anshuman.gupta@intel.com> --- drivers/gpu/drm/i915/display/intel_ddi.c | 3 + drivers/gpu/drm/i915/display/intel_display.c | 4 - .../drm/i915/display/intel_display_debugfs.c | 111 ++-- .../drm/i915/display/intel_display_types.h | 38 ++ drivers/gpu/drm/i915/display/intel_dp.c | 23 +- drivers/gpu/drm/i915/display/intel_psr.c | 576 ++++++++++-------- drivers/gpu/drm/i915/display/intel_psr.h | 14 +- drivers/gpu/drm/i915/display/intel_sprite.c | 6 +- drivers/gpu/drm/i915/i915_drv.h | 38 -- drivers/gpu/drm/i915/i915_irq.c | 49 +- 10 files changed, 485 insertions(+), 377 deletions(-)
