From c0459bddd1955df35c9331757671e64e3ea0a77a Mon Sep 17 00:00:00 2001 From: Alan Liu Date: Thu, 20 Oct 2022 11:46:42 -0400 Subject: drm/amd/display: Implement secure display on DCN21 [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.
