DP via USB sometimes does not work (dcn31_program_compbuf_size error)
Brief summary of the problem:
USB4 DP adapter sometimes does not work. I have to disconnect and reconnect until I get video output. It does not happen with any other hardware configuration.
Hardware description:
- CPU: AMD Ryzen 9 7900X
- GPU:
68:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Raphael [1002:164e] (rev c2) - System Memory: 2x32GB DDR5
- Display(s): LG Display GSM77BC, 3840x2160 @ 144 Hz
- Type of Display Connection: USB4 DP to HDMI 2.1
System information:
- Distro name and Version: Arch Linux
- Kernel version:
Linux 6.12.7-2-cachyos #1 SMP PREEMPT_DYNAMIC Fri, 27 Dec 2024 19:00:13 +0000 x86_64 GNU/Linux - Custom kernel: N/A
- AMD official driver version: N/A
- Kernel options:
rw zswap.enabled=0 nowatchdog splash
How to reproduce the issue:
I have the USB-C to DisplayPort adapter Cable matters 201310-BLK, which I am using to output a HDMI 2.1 signal from a USB4 DP-out port. I already updated the adapter to the latest available firmware.
Often, when I connect the dongle to the USB4 port, the signal is not transmitted and the monitor will detect no video to be displayed. To temporarily fix the issue I have to unplug and plug back the dongle multiple times until it works. This takes one to two attempts. Restarting the computer sometimes forces me to repeat this step until I get video output again. Once I get video output, it is stable and I can change resolution and refresh rate without issues.
I noticed this issue happening since at least July 2024 with Linux 6.10, when I bought the adapter. I do not have the same issue when using the adapter on my Macbook or my Steam Deck. The problem only happens using my Linux+AMD iGPU. I can safely rule out a problem in the adapter.
Please find the logs below.
Log files (for system lockups / game freezes / crashes)
The following dmesg.log shows once instance when the adapter is connected and there is no video output. Then it gets disconnected, re-connected to then successfully behave as expected.
