Linux 6.12 introduces optional support for displaying a QR code during kernel panics within the DRM Panic handler infrastructure. This QR code captures extensive debugging information that is often difficult to obtain from chopped-off text-based panic messages. To use this feature, the Rust kernel build must be enabled, and the DMR_PANIC_SCREEN_QR_CODE Kconfig build switch must be set. The QR code support is slated to be included in the Linux 6.12 merge window in mid-September.
