drm/amd/display: Make cursor source translation adjustment optional

2020-04-07T18:20:45Z

[Why] In some usecases, like tiled display, the stream and plane configuration can be setup in a way where the caller expects DAL to perform the clipping, eg: P0: src_rect(0, 0, w, h) dst_rect(0, 0, w, h) P1: src_rect(w, 0, w, h) dst_rect(0, 0, w, h) Cursor is enabled on both streams with the same position. This can result in double cursor on tiled display, even though this behavior is technically correct from the DC interface point of view. We need a mechanism to control this dynamically. [How] This is something that should live in the DM layer based on detection of the specified configuration but it's not something that we really have enough information to deal with today. Add a flag to the cursor position state that specifies whether we want DC to do the translation or not and make it opt-in and let the DM decide when to do it.

drm/amd/display: Fix incorrect cursor pos on scaled primary plane

2020-04-07T18:20:45Z

[Why] Cursor pos is correctly adjusted from DC side for source rect offset on DCN ASIC, but only on the overlay. This is because DM places offsets the cursor for primary planes only to workaround missing code in DCE for the adjustment we're now correctly doing in DC for DCN ASIC. [How] Drop the adjustment for source rect from the DM side of things and put the code where it actually belongs - in DC on the pipe level. This matches what we do for DCN now.

drm/amd/display: increase HDCP authentication delay

2020-03-31T16:44:29Z

[Why] Some displays have an issue where the hdcp chips are initialized after the display has already lit up. This means we can sometimes authentication too early and cause authentication failures. This happens when HDCP is enabled and the display is power cycled. Normally we will authenticate 2 seconds after the display is lit, but some displays need a bit more time. [How] Increase delay to 3 second before we start authentication. Signed-off-by: Bhawanpreet Lakha Reviewed-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amd/display: Don't try hdcp1.4 when content_type is set to type1

2020-03-31T16:44:29Z

[Why] When content type property is set to 1. We should enable hdcp2.2 and if we cant then stop. Currently the way it works in DC is that if we fail hdcp2, we will try hdcp1 after.
