Now Linux 6.10 is introducing a new DRM panic handler infrastructure enabling messages when a panic occurs, Phoronix reports today. “This is especially important for those building a kernel without VT/FBCON support where otherwise viewing the kernel panic message isn’t otherwise easily available.”
With Linux 6.10 the initial DRM Panic code has landed as well as wiring up the DRM/KMS driver support for the SimpleDRM, MGAG200, IMX, and AST drivers. There is work underway on extending DRM Panic support to other drivers that we’ll likely see over the coming kernel cycles for more widespread support… On Linux 6.10+ with platforms having the DRM Panic driver support, this “Blue Screen of Death” functionality can be tested via a route such as echo c > /proc/sysrq-trigger.
The article links to a picture shared on Mastodon by Red Hat engineer Javier Martinez Canillas of the error message being generated on a BeaglePlay single board computer.
Phoronix also points out that some operating systems have even considered QR codes for kernel error messages…
