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. This week was also the
last promotion test ran on Ubuntu 24.04. There won't be any testing this week
as we had a holiday this past Monday, so the first test on Ubuntu 26.04 will
begin next week.
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 ->
c08a3dc2b7ba7b4a0dd930fa5e58f8f1aab068cc -> drm/amd/display: Add
dcn42b_soc_and_ip_translator) with new patches added on top of it.
Tested on Ubuntu 26.04.4, on Wayland and X11, using Gnome.
