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
        • 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

The patchset consists of the amd-staging-drm-next branch (Head commit -> f07b314c2a3f70a487086150ef794c22d86b5a8b-> drm/amdgpu: Add wrapper function for dpc state) with new patches added on top of it.

Tested on Ubuntu 24.04.3, on Wayland and X11, using KDE Plasma and Gnome.
