[WHY] In certain scenarios DC can internally trigger back to back full updates which will miss some required programming that is normally deferred until post update via optimize_bandwidth. [HOW] In back to back update scenarios, wait for pending updates to complete and perform any strictly required outstanding programming. Reviewed-by:

[WHY&HOW] It is not guaranteed even for HW exclusive P-State methods (like VActive) that P-state will be supported properly until optimize bandwidth is called, so unconditionally disable it on full updates. Reviewed-by:

[WHY] Stream ID's associated with phantom pipes can change often as they are reconstructed on full updates, however they can remain identical depending on the required update. [HOW] In the case phantom streams and pipe topologies remain the same between updates, mark the transition as seamless. Reviewed-by:

This commit adds a null check for the 'afb' variable in the amdgpu_dm_plane_handle_cursor_update function. Previously, 'afb' was assumed to be null, but was used later in the code without a null check. This could potentially lead to a null pointer dereference. Changes since v1: - Moved the null check for 'afb' to the line where 'afb' is used. (Alex) Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:1298 amdgpu_dm_plane_handle_cursor_update() error: we previously assumed 'afb' could be null (see line 1252) Cc: Tom Chung <chiahsuan.chung@amd.com> Cc: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Cc: Roman Li <roman.li@amd.com> Cc: Alex Hung <alex.hung@amd.com> Cc: Aurabindo Pillai <aurabindo.pillai@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Co-developed-by:

Add helper function kfd_queue_unreference_buffers to reduce queue buffer refcount, separate it from release queue buffers. Because it is circular locking to hold dqm_lock to take vm lock, kfd_ioctl_destroy_queue should take vm lock, unreference queue buffers first, but not release queue buffers, to handle error in case failed to hold vm lock. Then hold dqm_lock to remove queue from queue list and then release queue buffers. Restore process worker restore queue hold dqm_lock, will always find the queue with valid queue buffers. v2 (Felix): - renamed kfd_queue_unreference_buffer(s) to kfd_queue_unref_bo_va(s) - added two FIXME comments for follow up Signed-off-by:

When users dynamically set the partition mode through sysfs writes, this can lead to a double lock situation where the KFD is trying to take the partition lock when updating the recommended SDMA engines. Have the KFD reference its saved socket device number count instead. Also ensure we have enough SDMA xGMI engines to report the recommended engines in the first place.

[WHY & HOW] dc->clk_mgr is null checked previously in the same function, indicating it might be null. Passing "dc" to "dc->hwss.apply_idle_power_optimizations", which dereferences null "dc->clk_mgr". (The function pointer resolves to "dcn35_apply_idle_power_optimizations".) This fixes 1 FORWARD_NULL issue reported by Coverity. Reviewed-by:

[Why] Currently the handling for 3DLUT is found in multiple different places, which causes issues when the different functions are not in sync with each other. Frequently bugs occur because the LUT handling is broken up, and what has already been handled isn't kept track of well, which can cause earlier changes to the LUT params to be overridden. [How] Remove DMA LUT handling from DCN401 and refactor legacy LUT handling in one place to make it easier to keep track of what has and needs to be done. Reviewed-by:
