drm/amd/display: Fix mem_type change detection for async flips

2026-06-17T22:17:33+00:00

[Why] amdgpu_dm_crtc_mem_type_changed() fetches the "old" and "new" plane state with two drm_atomic_get_plane_state() calls, which both return the new state. It compares a state against itself, so it never detects a mem_type change and never rejects the async flip. On DCN 3.0.1, this shows up as intermittent corruption when a single DCC plane is scanned out with immediate flips under gamescope and its buffer moves between the VRAM carveout and GTT. [How] Use drm_atomic_get_old_plane_state() and drm_atomic_get_new_plane_state() to compare the actual old and new states. These return NULL rather than an error pointer for a plane that is not part of the commit, so the IS_ERR() check becomes a NULL check that skips those planes, such as an unmodified cursor still in the CRTC's plane_mask.

drm/amd/display: Add IN_FORMATS_ASYNC support for planes

2026-06-17T22:16:57+00:00

[Why] The DRM core exposes an IN_FORMATS_ASYNC plane property describing the set of format/modifier pairs that are valid for asynchronous (immediate) page flips. amdgpu already advertises async page flip support via mode_config.async_page_flip = true, but never implemented the .format_mod_supported_async plane callback, so the IN_FORMATS_ASYNC property was not created. This inconsistency (advertising async flips while exposing IN_FORMATS but no IN_FORMATS_ASYNC) causes userspace, such as igt-gpu-tools, to emit a repeated warning during plane initialization, which in turn demotes many otherwise passing KMS subtests to a WARN result. [How] Wire up .format_mod_supported_async to the existing amdgpu_dm_plane_format_mod_supported callback so the async format list is populated. amdgpu does not restrict async flips at the format/modifier level: the async flip constraints are enforced at atomic check and commit time and only require a fast update (no change to FB pitch, DCC state, rotation or memory type) between the old and new buffers. Therefore the set of formats/modifiers valid for async flips is identical to the regular IN_FORMATS set, and the same callback can be reused.

drm/amd/display: Skip PHY SSC reduction on some 8K panels

2026-06-17T22:09:23+00:00

[Why] Some 8K displays cannot tolerate the reduced phy ssc value at high link utilization and show corruption or black screen. [How] Add an EDID panel-id quirk to utilize existing skip_phy_ssc_reduction flag. To pass the link into the quirk handler, change the signature of apply_edid_quirks() to take link as an argument. The dev local in dm_helpers_parse_edid_caps() becomes unused and is removed.

drm/amd/display: use plane color_mgmt_changed to track colorop changes

2026-06-10T10:13:37+00:00

Ensure the driver tracks changes in any colorop property of a plane color pipeline by using the same mechanism of CRTC color management and update plane color blocks when any colorop property changes. It fixes an issue observed on gamescope settings for night mode which is done via shaper/3D-LUT updates.
