Hi all,
This week this patchset was tested on 4 systems, two dGPU and two APU based, and tested across multiple display and connection types.
APU
* Single Display eDP -> 1080p 60hz, 1920x1200 165hz, 3840x2400 60hz
* Single Display DP (SST DSC) -> 4k144hz, 4k240hz
* Multi display -> eDP + DP/HDMI/USB-C -> 1080p 60hz eDP + 4k 144hz, 4k 240hz (Includes USB-C to DP/HDMI adapters)
* Thunderbolt -> LG Ultrafine 5k
* MST DSC -> Cable Matters 101075 (DP to 3x DP) with 3x 4k60hz displays, HP Hook G2 with 2x 4k60hz displays
* USB 4 -> HP Hook G4, Lenovo Thunderbolt Dock, both with 2x 4k60hz DP and 1x 4k60hz HDMI displays
* SST PCON -> Club3D CAC-1085 + 1x 4k 144hz, FRL3, at a max resolution supported by the dongle of 4k 120hz YUV420 12bpc.
* MST PCON -> 1x 4k 144hz, FRL3, at a max resolution supported by the adapter of 4k 120hz RGB 8bpc.
DGPU
* Single Display DP (SST DSC) -> 4k144hz, 4k240hz
* Multiple Display DP -> 4k240hz + 4k144hz
* MST (Startech MST14DP123DP [DP to 3x DP] and 2x 4k 60hz displays)
* MST DSC (with Cable Matters 101075 [DP to 3x DP] with 3x 4k60hz displays)
The testing is a mix of automated and manual tests. Manual testing includes (but is not limited to)
* Changing display configurations and settings
* Video/Audio playback
* Benchmark testing
* Suspend/Resume testing
* Feature testing (Freesync, HDCP, etc.)
Automated testing includes (but is not limited to)
* Script testing (scripts to automate some of the manual checks)
* IGT testing
The testing is mainly tested on the following displays, but occasionally there are tests with other displays
* Samsung G8 Neo 4k240hz
* Samsung QN55QN95B 4k 120hz
* Acer XV322QKKV 4k144hz
* HP U27 4k Wireless 4k60hz
* LG 27UD58B 4k60hz
* LG 32UN650WA 4k60hz
* LG Ultrafine 5k 5k60hz
* AU Optronics B140HAN01.1 1080p 60hz eDP
* AU Optronics B160UAN01.J 1920x1200 165hz eDP
* Samsung ATNA60YV02-0 3840x2400 60Hz OLED eDP
The patchset consists of the amd-staging-drm-next branch (Head commit - 5b618c86e32058864f039598aa1760c45649a7f0 -> drm/amd/display: Check dc_link before applying DSC policy) with new patches added on top of it.
Tested on Ubuntu 24.04.4, on Gnome Wayland.

Subject: [PATCH 00/70] DC Patches July 13, 2026
This DC patchset brings improvements in multiple areas. In summary, we have:
* Unified dc_update_state commit interface with dc_probe model,
dc_state_get_status, and perfmon BLS sequence
* DCN42 enhancements including mcache programming, PMFW DF C-state client,
and DCCG clocking fix
* DML2.1 writeback validation plus MCIF ARB and watermark/latency updates
* Color management refactor to dc_plane_cm with plane/CRTC colorop test coverage
* Greatly enhanced KUnit coverage across amdgpu_dm, connector, CRC, DMUB, and
color management
* HDMI AV mute timing, DP link training logging, and Apple Studio Display fixes
* Code cleanup including DCE trim from DCN-only builds and HWSS refactors
* SPL UPSP upsampling and YUV422/YUV444 scaling support
* Fix missing dc_3dlut forward declaration in color management KUnit headers
* Fix DM IRQ schedule-work KUnit tests after cancel_work_sync teardown change
