2020-09-15drm/amd/display: Add DSC force disable to dsc_clock_en debugfs entryEryk Brol
[why] For debug purposes we want not to enable DSC on certain connectors even if algorithm deesires to do so, instead it should enable DSC on other capable connectors or fail the atomic check. [how] Adding the third option to connector's debugfs entry dsc_clock_en. Accepted inputs: 0x0 - connector is using default DSC enablement policy 0x1 - force enable DSC on the connector, if it supports DSC 0x2 - force disable DSC on the connector, if DSC is supported Ex. # echo 0x2 > /sys/kernel/debug/dri/0/DP-1/dsc_clock_en Signed-off-by: Eryk Brol <eryk.brol@amd.com> Signed-off-by: Mikita Lipski <mikita.lipski@amd.com> Acked-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2020-09-15drm/amd/display: Multi display cause system lag on mode changeAric Cyr
[Why] DCValidator is created/destroyed repeatedly for cofunctional validation which causes a lot of memory thrashing, particularly when Driver Verifer is enabled. [How] Implement a basic caching algorithm that will cache DCValidator with a matching topology. When a match is found, the DCValidator can be reused. If there is no match, a new one will be created and inserted into the cache if there is space or an unreference entry can be evicted.

2020-09-15drm/amd/display: Don't use DRM_ERROR() for DTM add topologyBhawanpreet Lakha
[Why] Previously we were only calling add_topology when hdcp was being enabled. Now we call add_topology by default so the ERROR messages are printed if the firmware is not loaded. This error message is not relevant for normal display functionality so no need to print a ERROR message.

2020-09-15drm/amd/display: Compare plane when looking for pipe split being lostAlvin Lee
[Why] There are situations where we go from 2 pipe to 1 pipe in MPO, but this isn't a pipe split being lost -- it's a plane disappearing in (i.e. video overlay goes away) so we lose one pipe. In these situations we don't want to disable the pipe in a separate operation from the rest of the pipe programming sequence. We only want to disable a pipe in a separate operation when we're actually disabling pipe split. [How] Make sure the pipe being lost has the same stream AND plane as the old top pipe to ensure.

[Why] ABM feature initialization was not executed due to early return. dm_late_init() had an early return in case if DMCU is not used.

2020-09-15drm/amd/display: Power eDP panel back ON before link training retryAshley Thomas
[why] When link training failures occur for eDP, dp_disable_link_phy is called which powers OFF eDP panel. After link training retry delay, the next retry begins by calling dp_enable_link_phy which does not issue a correspnding eDP panel power ON, leaving panel powered OFF which leads to display OFF/dark.

2020-09-15drm/amd/display: Only use offset for first ODM pipeWesley Chalmers
[WHY] Only the first pipe in ODM combine group should have nonzero recout offset. All other pipes should have recout offset 0; otherwise there will be gaps in the image. [HOW] Set recout.x to 0 if the pipe is not the leftmost ODM pipe. When computing viewports, calculate the horizontal offset of a pipe's src based on the current pipe's position in the ODM group, plus whatever offset the leftmost ODM pipe has; otherwise there will be discontinuity in the image. Since ODM combine can only combine pipes horizontally, nothing needs to be done for recout.y.

During the load processes for Renoir, our display code needs to retrieve the SMU clock and voltage table, however, this operation can fail which means that we have to check this scenario. Currently, we are not handling this case properly and as a result, we have seen the following dmesg log during the boot: RIP: 0010:rn_clk_mgr_construct+0x129/0x3d0 [amdgpu] ... Call Trace: dc_clk_mgr_create+0x16a/0x1b0 [amdgpu] dc_create+0x231/0x760 [amdgpu] This commit fixes this issue by checking the return status retrieved from the clock table before try to populate any bandwidth.

And then kfd_process_evict_queues will access a freed memory, which cause a system crash. v2: The failure to execute_queues should probably not be reported to the caller of create_queue, because the queue was already created. Therefore change to ignore the return value from execute_queues.
