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: send pipe set command to dmcu when stream unblanks

2019-02-19T20:58:26Z

[Why] When stream is blanked, pipe set command is sent to dmcu to notify it that the abm pipe is disabled. When stream is unblanked, no notification is made to dmcu that the abm pipe has been enabled, resulting in abm not being enabled in the firmware. [How] When stream is unblanked, send a pipe set command to dmcu. Signed-off-by: Josip Pavic Reviewed-by: Anthony Koo 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. [How] First step is to isolate the pipe related init code Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: refactor out programming of vupdate interrupt

2019-02-06T18:30:52Z

[Why] More clearly isolate the code that is involved in programming of vupdate interrupt [How] Add function for programming of vupdate interrupt. Call it after timing is programmed.

drm/amd/display: interface to check if timing can be seamless

2019-02-06T18:30:44Z

[Why] Need to figure out whether a timing we want to commit matches something that GOP already programmed, in which case we can decide to some optimizations [How] 1. Add way to check for DIG FE 2. Add way to check for matching OTG timing 3. Add way to check for matching pixel clock (if possible) - Currently only support DP for pixel clock, since it is easy to calc Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: DC VM Fixes

2019-02-06T18:30:12Z

[Why] VM_helper needs to be intialized with the dc struct in order to fix an unallocated memory issue. System aperture settings should be initialized to 0 and guarded with a check to make sure vm_config is valid. [How] Allocate and free memory for vm_helper with other dc members. Check whether the vm_config valid bit is set before initializing aperture settings. Signed-off-by: Eryk Brol Reviewed-by: Jun Lei Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher
