[PATCH 03/23] drm/amd/display: Implement multiple secure display
jdhillon
jdhillon at amd.com
Fri Dec 9 16:36:27 UTC 2022
From: Alan Liu <HaoPing.Liu at amd.com>
[Why]
Current secure display only work with single display, now make it
work with multiple displays.
[How]
Create secure_display_context for each crtc instance to store its
own Region of Interest (ROI) information.
