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 ->
e057322aedb24072dc6c7f531b1bbbaa0497c31b -> drm/amd/ras: report the bad page
threshold in every work mode) with new patches added on top of it.
Tested on Ubuntu 26.04, on Gnome Wayland.

Subject: [PATCH 00/30] DC Patches October 19, 2026
This DC patchset brings improvements in multiple areas. In summary, we have:
- Fix HDMI FRL FFE compliance test and adjust FRL LT timeout.
- Align eDP DSC link policy to minimize lane count.
- Add AS-SDP V3 support for VESA Panel Replay.
- Add DPG force-on-flip support.
- Log PSR/Replay status and exit PSR/Replay on non-modeset full updates.
- Reject invalid per-mode FreeSync timing and set VRR_EN state.
- Align VRR timing gate with FreeSync module.
- Warn on unadvertised modes without scaling.
- Use DMUB to notify PME and update DMU cmd header.
- Do not allow vbios version of dmubfw in the driver.
- Use picoseconds for line time and correct next frame calculation.
- Fix YUV422 semi-planar color blurring and UPSP chroma upsampling.
- Reset UPSP and pre-CSC registers on DCN6 DPP reset.
- Handle exit LS in second ISHARP programming block.
- Remove hard-coded min dcfclk for AC.
- Do not WARN when removing an unallocated MST payload.
- Various cleanups, KUnit test fixes and debug flag gating.
