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 -
b146e31a43c6b52ecb014512ea113af7cd11118a -> drm/amd/display: Add missing post
flip calls) with new patches added on top of it.
Tested on Ubuntu 24.04.3, on Wayland and X11, using Gnome.
