drm/amd/display: Disable phantom OTG after enable for plane disable

2022-11-09T22:25:45Z

[Description] - Need to disable phantom OTG after it's enabled in order to restore it to it's original state. - If it's enabled and then an MCLK switch comes in we may not prefetch the correct data since the phantom OTG could already be in the middle of the frame.

drm/amd/display: Drop struct crc_region and reuse struct rect

2022-10-27T18:42:40Z

[Why] reuse struct rect rather than adding a new struct. [How] - Userspace keeps inputting x_start, y_start, x_end, y_end - We translate data to x, y, width, height in code flow to store - translate back to x_start, y_start, x_end, y_end before programming HW Tested-by: Mark Broadworth Reviewed-by: Wayne Lin Acked-by: Rodrigo Siqueira Signed-off-by: Alan Liu Signed-off-by: Alex Deucher

drm/amd/display: Implement secure display on DCN21

2022-10-27T18:42:32Z

[Why] Porting secure display feature from DCN10 to DCN21. Support single display for now and will extend to multiple displays. [How] - use workqueue to offload works for dmub or dmcu firmware - after receiving ROI update from userspace, set skip_frame_cnt to 1 - refactor amdgpu_dm_crtc_handle_crc_window_irq() - disable PSR before activating secure_display on a crtc - check if secure_display is activated before enabling psr - only work for single display for now.
