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.

[why & how] VBIOS DMCUB FW can enable FEC for capable eDPs, but S/W DC state is only updated for link0 when transitioning into OS with driver loaded. This causes issues when the eDP is immediately hidden and DIG0 is assigned to another link that does not support FEC. Driver will attempt to disable FEC but FEC enablement occurs based on the link state, which does not have fec_state updated since it is a different link. Thus, FEC disablement on DIG0 will get skipped and cause no light up.

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.

2026-01-14drm/atomic: add max_size check to drm_property_replace_blob_from_id()Dmitry Baryshkov
The function drm_property_replace_blob_from_id() allows checking whether the blob size is equal to a predefined value. In case of variable-size properties (like the gamma / degamma LUTs) we might want to check for the blob size against the maximum, allowing properties of the size lesser than the max supported by the hardware. Extend the function in order to support such checks.

2026-01-10drm/amd/display: Adjust PHY FSM transition to TX_EN-to-PLL_ON for TMDS on DCN35Nicholas Kazlauskas
[Why] A backport of the change made for DCN401 that addresses an issue where we turn off the PHY PLL when disabling TMDS output, which causes the OTG to remain stuck. The OTG being stuck can lead to a hang in the DCHVM's ability to ACK invalidations when it thinks the HUBP is still on but it's not receiving global sync. The transition to PLL_ON needs to be atomic as there's no guarantee that the thread isn't pre-empted or is able to complete before the IOMMU watchdog times out. [How] Backport the implementation from dcn401 back to dcn35. There's a functional difference in when the eDP output is disabled in dcn401 code so we don't want to utilize it directly.
