[why] Currently the amdgpu DM psr configuration parameters are hardcoded before feeding into the DC helper to setup PSR. We would define a helper which is to calculate parts of the psr config fields to avoid hard-coding. [how] To make helper shareable, declare and define the helper in the module_helper, to set/update below fields: - psr remote buffer setup time - sdp tx line number deadline - line time in us - su_y_granularity - su_granularity_required - psr_frame_capture_indication_req - psr_exit_link_training_required add another helper to check given the stream context, if there is only one stream and the output is eDP panel connected. changes in v2: ------------------ - add detailed comment for how psr setup time is calculated as per eDP 1.5 spec Cc: Chandan Vurdigerenataraj <chandan.vurdigerenataraj@amd.com> Signed-off-by: David Zhang <dingchen.zhang@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |
