2025-03-05drm/amdgpu: Remove powerdown_uvd memberDr. David Alan Gilbert
With phm_powerdown_uvd() gone in the previous patch, there's now no longer anything that reads the powerdown_uvd member of the pp_hwmgr_func. Remove it. There are a few assignments to it; a boring NULL which can just go, and two functions, but those functions are called explicitly anyway so the assignments to the member go. One of those (smu7_powerdown_uvd) wasn't static previously; make it static. Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-03-05drm/amd/display: Add a new dcdebugmask to allow turning off brightness curveMario Limonciello
Upgrading the kernel may cause some systems that were previously not using a firmware specified brightness curve to use one. In the event of problems with this curve (for example an interpolation error) add a new dcdebugmask value that can be used to turn it off. Also add an info message to show that custom brightness curves are currently in use.

2025-03-05drm/amd/display: Ensure DMCUB idle before reset on DCN31/DCN35Nicholas Kazlauskas
[Why] If we soft reset before halt finishes and there are outstanding memory transactions then the memory interface may produce unexpected results, such as out of order transactions when the firmware next runs. These can manifest as random or unexpected load/store violations. [How] Increase the timeout before soft reset to ensure the DMCUB has quiesced. This is effectively 1s maximum based on experimentation. Use the enable bit check on DCN31 like we're doing on DCN35 and reorder the reset writes to follow the HW programming guide. Ensure we're reading SCRATCH7 instead of SCRATCH8 for the HALT code. No current versions of DMCUB firmware use the SCRATCH8 boot bit to dynamically switch where the HALT code goes to maintain backwards compatibility with PSP.

There is a type mismatch between what CalculateDynamicMetadataParameters() takes and what is passed to it. Currently this function accepts several args as signed long but it's called with unsigned integers and integer. On some systems where long is 32 bits and one of these unsigned int params is greater than INT_MAX it may cause passing input params as negative values. Fix this by changing these argument types from long to unsigned int and to int respectively. Also this will align the function's definition with similar functions in other dcn* drivers.

The mask is updated to reflect the state of both the SDMA gfx ring and the page queue.
