2024-02-22drm/amd/display: Drop unnecessary headerRodrigo Siqueira7-14/+0
A long time ago, the slab header was added to multiple files in DC. We also included it in the os_types.h, which is included in many of those DC files. At this point, there is no need to insert the slab.h header in multiple files, so this commit drops those includes.

2024-02-22drm/amd/display: reenable windowed mpo odm support on dcn32 and dcn321Wenjing Liu2-1/+2
[why] The feature was disabled due to regression found during testing. Now that all the pending issues are addressed, we are reenabling the power saving feature again. The feature optimizes dispclk level when user is using MPO capable broswers or watching MPO capable videos in windowed mode. The feature achieves power optimization by utilizing free pipes to process incoming pixels in parallel. So it reduces max dispclk requirements for each pipe. Previously ODM power optimization will be disabled when MPO plane is present due to technical challeges. This is mainly because ODM divides pixel workload with respect to stream but MPO plane position and size are arbitrary with respect to stream. The pixel processing workload of an MPO plane is not guarenteed to be evenly distributed across DCN pipes. For example if a plane is moved inside single ODM slice, all the processing for the plane is distributed to the pipe in the current ODM slice, while the other ODM slices don't need to process this plane. If the plane is then moved to the middle crosing two ODM slices, each ODM slice gets half of the workload. This is especially difficult when the plane itself has a large source rect which can't be processed by single DCN pipe. In this case we can't enable ODM power optimization when the plane is only within one ODM slice. [how] To overcome the challeges, new pipe resource management is in place to make sure a plane is validated with ODM power optimization support if it can be validated regardless of its position and the same pipe topology can be used regardless of the plane's position. When the plane is moved outside current ODM slice, we will set recout to 0 so the pipe can be idling without the need to update pipe topology. When the user resizes a plane, it may result in downscaling ratio changes. When the downscaling ratio is above single pipe's threshold, we will seamlessly exit ODM power optimization and applies MPC combine to support the plane. when downscaling ratio becomes smaller, we will seamlessly enter ODM power optimization again. All these pipe transitions happen automatically and quietly when the conditions are met without any visual impacts to the user.

2024-02-22drm/amd/display: Generalize new minimal transition pathAlvin Lee2-100/+77
Previously the new minimal transition path was only used for windowed MPO + ODM for plane scaling updates. However, we want to generalize the transition for all cases whenever a non-seamless transition is detected (such as for MPO -> SubVP + MPC). To make this change we add pointers in the plane state, stream, and pointers in the stream state to the dc_scratch state and backup and restore these so the minimal transition can take place successfully.

2024-02-22drm/amd/display: Fix potential null pointer dereference in dc_dmub_srvSrinivasan Shanmugam1-2/+5
Fixes potential null pointer dereference warnings in the dc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up() functions. In both functions, the 'dc_dmub_srv' variable was being dereferenced before it was checked for null. This could lead to a null pointer dereference if 'dc_dmub_srv' is null. The fix is to check if 'dc_dmub_srv' is null before dereferencing it. Thus moving the null checks for 'dc_dmub_srv' to the beginning of the functions to ensure that 'dc_dmub_srv' is not null when it is dereferenced.

The scheduler depends upon these pages being resident and fails, preventing a debugger from inspecting the failure state. By relocating these pages above 47 bits in the VM address space they can only be reached when bits [63:48] are set to 1.

As part of a cleanup amdgpu_dm_fini() function, which is typically called when a device is being shut down or a driver is being unloaded The below error message suggests that there is a potential null pointer dereference issue with adev->dm.dc. In the below, line of code where adev->dm.dc is used without a preceding null check: for (i = 0; i < adev->dm.dc->caps.max_links; i++) { To fix this issue, add a null check for adev->dm.dc before this line. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:1959 amdgpu_dm_fini() error: we previously assumed 'adev->dm.dc' could be null (see line 1943) Fixes: 006c26a0f1c8 ("drm/amd/display: Fix crash on device remove/driver unload") Cc: Andrey Grodzovsky <[email protected]> Cc: Harry Wentland <[email protected]> Cc: Rodrigo Siqueira <[email protected]> Cc: Aurabindo Pillai <[email protected]> Signed-off-by: Srinivasan Shanmugam <[email protected]> Reviewed-by: Roman Li <[email protected]> Reviewed-by: Aurabindo Pillai <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
