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: add seamless boot flag to stream

2019-02-06T18:31:07Z

[Why] If we determine the stream we are trying to commit matches HW, we want to try to optimize. [How] Try to acquire the HW resources that are already enabled and optimize.

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

drm/amd/display: add stream ID and otg instance in dc_stream_state

2019-01-14T20:04:37Z

[why] stream ID allows DMs to avoid memory address comparisons to compare stream equality. otg_instance allows DC to more rigorously define when otg_instance can change. specifically, it is now defined to be only mutable when dc_stream_state changes. This is better than a "get status" function which prevents efficient caching of otherwise very stable information. [how] stream ID follows similar pattern to sink ID, which is already implemented otg_instance is an output which occurs on all dc_stream modification functions Signed-off-by: Jun Lei Reviewed-by: Tony Cheng Acked-by: Aric Cyr Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: Detach backlight from stream

2019-01-14T20:04:36Z

[Why] Backlight is conceptually a property of links, not streams. All backlight programming is done on links, but there is a stream property bl_pwm_level that is used to restore backlight on dpms on and s3 resume. This is unnecessary, as backlight is already restored by hardware with no driver intervention.
