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: Ungate stream before programming registers

2019-02-19T20:58:26Z

[Why] Certain tests fail after a fresh reboot. This is caused by writing to registers prior to ungating the stream we're trying to program. [How] Make sure the stream is ungated before writing to its registers. This also enables power-gating plane resources before init_hw initializes them. Additionally, this does some refactoring to move gating/ungating from enable/disable_plane functions to where stream resources are enabled/disabled.

drm/amd/display: remove screen flashes on seamless boot

2019-02-19T20:58:26Z

[Why] We want boot to desktop to be seamless [How] During init pipes, avoid touching the pipes where GOP has already enabled the HW to the state we want. Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: refactor init_hw to isolate pipe related init

2019-02-06T18:31:22Z

[Why] Pipe related init is possible to optimized if we know what we intend to program, and if we can determine it matches what is already programmed for the pipe.

drm/amd/display: refactor programming of DRR

2019-02-06T18:31:15Z

[Why] Keep enable_stream_timing programming only timing related stuff.

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: refactor out programming of vupdate interrupt

drm/amd/display: Use context parameters to enable FBC

2019-02-06T02:16:22Z

[What] FBC fails to get enabled when switched between LINEAR(console/VT) and non-LINEAR(GUI) based rendering due to default value of tiling info stored in the current_state which is used for deciding whether or not to turn FBC on or off. [How] Use context structure's tiling information which is coherant with the screen updates. Signed-off-by: Shirish S Reviewed-by: Roman Li Signed-off-by: Alex Deucher
