In this context DRM stands for Direct Rendering Manager.

It has nothing to do with digital rights management.

It seems like this is already deployed in Arch, as I've hit it yesterday. I was surprised at first, but it was quite useful.

Do not want. More dumbing down and opaqueing? This is as stupid as what happened to Windows' BSoDs.

Fun, and nice addition, but again another good example of let's sneak some rust in critical parts of the kernel so that rust will become mandatory.

I would not really have noticed if there wasn't this section about why rust, where arguments looks phony and clearly made up afterward to justify a decision that was already taken:

   This project was written in rust, because memory safety is critical in a panic handler.

   For this particular case, I found the Rust code to be cleaner, and easier to read.

How am I supposed to use a QR code when the only thing that I have to decode it is currently panicking? If I am supposed to draw it I hope it is only a few bits. A traditional BSOD with codes and registers would be easier to copy.

This is awesome. I can't tell you how many times in my life I've been sent a photo of a Linux panic bracktrace with the first half missing because the screen couldn't display enough lines...

Funny story: on an x86 motherboard with no serial, I recently resorted to using an old 4K monitor with the 4x6 tiny console font to catch a panic (that netconsole wouldn't log for some reason).

I am disappointed to see that the QR code is completely replacing the panic messages. There is plenty of room on most monitors to have a stack trace on one side and the QR code on the other.

I probably won't be enabling this on my machines, but good on them for trying to improve on the Linux panic screen.
