coreboot

sure sounds to me like the USB-C port on the card is causing SeaBIOS'
USB init to fail. I'm guessing nothing at all to do with coreboot.
Raise the SeaBIOS logging level to 3 and grab a cbmem log after
booting

Bug #414: X9SAE-V: No USB keyboard init with SeaBIOS while using Radeon RX 6800XT
https://ticket.coreboot.org/issues/414

• Author: Aaron Burton
• Status: New
• Priority: Normal
• Category: board support
• Target version: none
• Start date: 2022-09-05
• Affected versions: 4.17

* Affected hardware: X9SAE-V¶

While booting coreboot 4.17 to SeaBIOS 1.16 on a Supermicro X9SAE-V, the keyboard flashes on then off (LED Backlit USB keyboard) and does not let me interact with SeaBIOS until the linux kernel is loaded on the OS side. Currently using a PS/2 keyboard to unlock my boot drive via SeaBIOS. Using any other GPU does not affect the USB keyboard and works just fine. The Radeon RX 6800XT is a reference card with a USB-C port on it, naturally I tried a USB-C adaptor on the GPU to get the USB keyboard to work, but no luck. Building coreboot with either native, secure VGABIOS loading, or libgfxinit does not fix the problem either. Seems to be specific to this GPU on hardware init. Coreboot dot config is attached.

Thank you for uploading the logs. (Looking at them, it’s better to use util/cbmem/cbmem instead of the Linux kernel module, as that does not support the log level markers.)

Using any other GPU does not affect the USB keyboard and works just fine.

Can you please elaborate, how you connect the keyboard then? Also with the Radeon RX 6800XT, does the USB keyboard never work, or just when you connect it to the USB Type-C port of the graphics card?

Is the port we are trying to use on the PCI address 03:00.2?

SeaBIOS detects a USB hub, but I guess it’s a different one?

|7fecc000| Initialized USB HUB (1 ports used)

How is your setup exactly? What keyboard is it, and how is it connected exactly?

Can you please try with SeaBIOS master, and also output lspci -nn and lsusb and lsusb --tree from GNU/Linux?

Thanks for looking at the logs. My USB keyboard is plugged directly into the motherboard at the back. With the 6800XT installed, the USB keyboard isn't functional until I boot into Linux, then it begins to work once the kernel is loaded. It's the same situation if I run a USB-C hub off the 6800XT, no keyboard output until I boot into Linux. The hub you see there is more than likely the USB 3 hub I use for extra peripherals. The keyboard is:
Bus 002 Device 003: ID 28da:1505 G.SKILL KM360 MX in Linux. That PCI address would be the USB-C controller on the 6800XT, which I don't use, only for testing to see if my keyboard would work in SeaBIOS through it. My setup consists of a traditional desktop setup, single monitor using DisplayPort. One of the first things I tried before posting here was running the SeaBIOS master branch, but I get the same result.
