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 - ab638da61c278a66ff51d44b89834444a0014894 ->drm/amdgpu: Replace HQD terminology with slots naming) with new patches added on top of it.

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