[Why] psr doesn't get fully disabled before hitting hubbub1_wm_change_req_wa. [How] Pass TRUE to "wait" parameter to get psr fully disabled. Follow-Up fix to: dc: PSR eDP p-state warning occurs intermittently after unplug DP Signed-off-by:

[why] We want to trigger atomic check on connector, which DSC debugfs properties have changed. [how] Add a helper function that iterates through all active connectors and add them to the state if DSC debugfs parameters have changed. Signed-off-by:

[why] When comparing current DSC timing settings with enforced through debugfs we have to calculate number of both vertical and horisontal slices. So instead of doing that every time we should just use number of slices rather than setting its dimensions. [how] In connector's dsc preferred settings structure change slice height and slice width parameters to number of slices vertical and horisontal. Also calculate number of slices in debugfs rather in create_stream_for_sink. Signed-off-by:

[why & how] Previously we were returning the number of bytes allocated for a write buffer from debugfs and when manually used it wouldn't rise any errors, but it wouldn't match the size of the parameters passed from userspace. In successful case return the size passed by usermode otherwise the error code is returned. That simplifies the parser helper and removes a potential error of returning mismatched input size.

[why] We need a virtual tool that would emulate a physical connector unplug to usermode, while connector is still physically plugged in. [how] Added a new option to debugfs entry "trigger_hotplug". It emulates hotplug irq handling scenario by clearing DC and DM connector states. It can be triggered with the following command: echo 0 > /sys/kernel/debug/dri/0/DP-X/trigger_hotplug Signed-off-by:

[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: -

[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. Signed-off-by:

[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. [How] Change DRM_ERROR to DRM_INFO Signed-off-by:

[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] PSR needs to be enabled on DCN30. This is the driver part of PSR enablement. Also disabled retired DMCU on driver side, since DMCU is not supported on DCN30 anymore. [How] Add necessary changes to enable PSR on DCN30. Signed-off-by:

[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. With the implementation of ABM on DMUB, DMCU can be disabled but ABM still needs to be initialized. [How] Remove verification for DMCU from the top of the function. The existing logic will handle the case when DMCU is not used. Signed-off-by:

[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. [how] Power ON eDP before next link training retry. Signed-off-by:

[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. Signed-off-by:

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.
