The infra for a "blue screen of death" in the #LinuxKernel has landed in #linux-next[1] and thus is slated for inclusion in #kernel 6.10:

"'This introduces a new drm panic handler, which displays a message when a panic occurs. So when fbcon is disabled, you can still see a kernel panic.

[…]

It works with simpledrm, mgag200, ast, and imx.

[…]

Even if this is not yet useful, it will allows to work on more driver support, […]"'

@kernellogger I had bad feeling when Microsoft started contributing to Linux kernel :-).

@pavel @kernellogger Nah, they're now on the same boat with us, being chased by the other big fish…

@kernellogger such copycats. ;-)

@kernellogger I always has been wondering why Linux doesn't have anything like that.

@a1ba

because it was hard to realize given the graphics stack and its history; you get a brief idea here:

https://dri.freedesktop.org/docs/drm/gpu/todo.html#make-panic-handling-work

@pid_eins

Who speaks there?

An employee of a well known company that has something like that for many years now or the maintainer of a software that later implemented something like that? ;-)

/me runs and hides

@kernellogger makes sense, thank you

@kernellogger i think the underlying goal of "make it possible to run linux systems without VTs/fbcon (and, if necessary, use wayland to provide a recovery console)" is kinda interesting

personally gonna miss the ol' reliable framebuffer console, but the fact it's so full of hard-to-maintain code that a security vulnerability had to be fixed by just disabling scrollback kinda proves that its time is way past

@rnd

yeah!

Somehow I lost track what will serve as replacement(s) for systems that want/need one. Kmscon seems kinda stalled. Or is there something else in the works?

@kernellogger We need a 'sad tux' for it.

@ptesarik @kernellogger It looks like we are on the same boat with the big fish, too :-). Plus, Microsoft is still evil -- yes, they need Linux, so they contribute a bit, but the way they push Windows 11 and Office subscription is unethical. They are not cool open source company...

@pavel @kernellogger 🤔

@kernellogger it was supposed to be a very meta comment.
