drm/amd/display: Expose audio inst from DC to DM

2019-08-06T17:08:09Z

[ Upstream commit 5fdb7c4c7f2691efd760b0b0dc00da4a3699f1a6 ] [Why] In order to give pin notifications to the sound driver from DM we need to know whether audio is enabled on a stream and what pin it's using from DC. [How] Expose the instance via stream status if it's a mapped resource for the stream. It will be -1 if there's no audio mapped.

drm/amd/display: Refactor for setup periodic interrupt.

2019-02-19T20:58:27Z

[Why] Current periodic interrupt start point calc in optc is not clear. [How] 1. DM convert delta time to lines number and dc will calculate the start position as per lines number and interrupt type. 2. hwss calculates the start point as per line offset. 3. optc programs vertical interrupts register as per start point and interrupt source.

drm/amd/display: Fix driver load crash in amdgpu_dm

2019-01-14T20:04:40Z

[Why] This fixes an regression introduced by: drm/amd/display: add stream ID and otg instance in dc_stream_state During driver initialization, a null pointer deref is raised. This is caused by searching for a stream status in the dc->current_state before the dc_state swap happens at the end of dc_commit_state_no_check(). Since the swap has not happened, the dc_state to be swapped in should be searched, and not dc->current_state. [How] Add a function that searches for the stream status within the given dc_state, instead of dc->current_state. Use that before the state swap happens in dc_commit_state_no_check(). Also remove duplicate occurrences of this function in amdgpu_dm.c. Signed-off-by: Leo Li Reviewed-by: Harry Wentland Acked-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher
