Phoronix: Nouveau DRM_Panic Being Worked On For Linux "Blue Screen Of Death" Type Situations

Merged for Linux 6.10 is DRM_Panic as a kernel panic screen for situations akin to Windows' well known "Blue Screen of Death". This is a kernel-based panic screen as an alternative to systemd's recent systemed-bsod. Patches have been posted by Red Hat for allowing the open-source NVIDIA "Nouveau" Direct Rendering Manager driver to work with DRM Panic...

Typo: "...systemd's recent systemed-bsod" - should just be "systemd-bsod".

Thank you Red Hat and Michael. I use Nouveau with a couple older Nvidia cards and it works great; never seen a kernel panic yet. I think this can wait until 6.11. BTW, AMD GPU driver also needs a check for GPU memory overflow. My 5700G locks up the system when the GPU RAM overflows.

Also systemd-bsod isnt an alternative to this. sd-bsod is about boot errors, while this is just about general kernel panics.

It's about any log message printed with the EMERG priority level.

I have 5700g too, how would I reproduce this bug, never noticed it? Shouldn't the video memory be dynamic anyway?

I ran the Cyberbunk benchmark using ultra texture at 720P, kernel 6.9.2 on FC40 and Plasma 6. Game starts but benchmarking ends up with black screen. Low texture runs fine.
