Does not work on Fedora + (fedora / vanilla+patch) 6.7.5 kernel

[perillamint]

Hello, I'm currently trying to use VivePro2 Linux driver on Fedora 39, but unable to make it work.

System specification

OS: Fedora Linux 39 (KDE Plasma) x86_64 Motherboard: AsRock X670E PG Lightning Kernel: Tested on Vanilla 6.7.5 + patch and Fedora 6.7.5 CPU: AMD Ryzen 9 7950X (32) @ 5.881GHz GPU: AMD ATI Radeon RX 6900 XT

Tested version: 8982075490c242bfb291cf997c07ade37357e558, with following patch to make it compile

        Ok(())
 }

Connection: Plugged linkbox to graphics card using bundled DP to miniDP cable.

Expected behavior

HMD work as normal

Actual behavior

• Right after SteamVR launch OR DP cable replug, display freezes
• SteamVR says critical component is crashed OR failed to open display.
• HMD LED stays red

Note

Due to the kernel log, I sent the Vive Pro 2 to repair, but service center says HMD is perfectly fine.

I suspect a hardware fault (because it failed to train DP), but I don't have any extra hardware (other graphics card OR another set of Vive Pro 2) to bisect the fault location...

Another notable thing is, UEFI firmware freezes when I try to boot the system with initialized Vive Pro 2

This is somewhat ok, my motherboard tries to render its UI on HMD with huge resolution too.

Did you changed your display mode to 4/5 in the config file? It requires gpu in the special mode, which doesn't work OOB, because I haven't managed to finish submitting this patch to the upstream: https://lore.kernel.org/linux-kernel/20220220151940.58327-1-iam@lach.pw/

Modes 0-3 should work, and then it is possible hardware failure. Can you test if your HMD works under windows?

[perillamint]

@CertainLach No, I stayed in 0-3, also tried 4, but result was same.

I think I can try it on Windows after I plug in extra SSD in my system (this weekend maybe)

[perillamint]

@CertainLach Tested it on Windows 11, With latest Radeon Adrenaline driver.

The headset LED switches to green, but desktop freezes (I guess the reason is same as Linux, AMD DC freaked out of PHY issue)

Now, it is clear: I need to physically visit them WITH my graphics card and I also suspects they didn't properly tested LinkBox

[CertainLach]

I don't think the reason is in the graphics card. You can try to reseat all the cables, including link cable on the headset side.

Dropping an update here: The service technician told me that it works on their machine (Nvidia GPU) and requested me to submit the log using a Windows driver. I did that today and will post here if there is an any update
