2026-01-22Revert "drm/amd/display: pause the workload setting in dm"Alex Deucher
This reverts commit bc6d54ac7e7436721a19443265f971f890c13cc5. The workload profile needs to be in the default state when the dc idle optimizaion state is entered. However, when jobs come in for video or GFX or compute, the profile may be set to a non-default profile resulting in the dc idle optimizations not taking affect and resulting in higher power usage. As such we need to pause the workload profile changes during this transition. When this patch was originally committed, it caused a regression with a Dell U3224KB display, but no other problems were reported at the time. When it was reapplied (this patch) to address increased power usage, it seems to have caused additional regressions. This change seems to have a number of side affects (audio issues, stuttering, etc.). I suspect the pause should only happen when all displays are off or in static screen mode, but I think this call site gets called more often than that which results in idle state entry more often than intended. For now revert.

2026-01-14drm/amd/display: Initialise backlight level values from hwVivek Das Mohapatra
Internal backlight levels are initialised from ACPI but the values are sometimes out of sync with the levels in effect until there has been a read from hardware (eg triggered by reading from sysfs). This means that the first drm_commit can cause the levels to be set to a different value than the actual starting one, which results in a sudden change in brightness. This path shows the problem (when the values are out of sync): amdgpu_dm_atomic_commit_tail() -> amdgpu_dm_commit_streams() -> amdgpu_dm_backlight_set_level(..., dm->brightness[n]) This patch calls the backlight ops get_brightness explicitly at the end of backlight registration to make sure dm->brightness[n] is in sync with the actual hardware levels.

2025-12-08drm/amd/display: Add additional checks for PSP footer sizeOvidiu Bunea
[WHY & HOW] Newer ASICs have different PSP footer sizes which lead to driver failing to locate the DMCUB FW meta info, which in turn causes improper DMCUB FW loading and causes DMCUB to crash. Add support for custom PSP footer sizes and check 512B by default as well.

2025-12-08drm/amd/display: Permit DC_FP_START/END only in non-FP compilation unitsArd Biesheuvel
[WHAT] Test the existing CPP macro _LINUX_FPU_COMPILATION_UNIT, which is set when building source files that are permitted to use floating point, in the implementation of DC_FP_START/END so that those are only usable in non-FP code. This is a requirement of the generic kernel mode FPU API, as some architectures (i.e., arm64) cannot safely enable FP codegen in arbitrary code.
