Merged for Linux 6.10 is DRM_Panic as a kernel panic screen for situations akin to Windows' well known 'Blue Screen of Death'

Red Hat engineers have been developing Nova as a new, Rust-written open-source NVIDIA kernel graphics driver as the eventual successor to the Nouveau kernel driver and is designed around NVIDIA's GPU System Processor (GSP) thus making the driver relevant for RTX 20 / Turing GPUs and newer

Sent in to DRM-Next as part of last week's drm-misc-next changes is implementing support for tracking cleared free memory and is initially wired up for the AMDGPU kernel graphics driver.

Intel's open-source Linux graphics driver engineers have been busy working to enable the display support for the upcoming Battlemage graphics cards as the successor to DG2/Alchemist.

While systemd 255 last year introduced a 'blue screen of death' inspired solution with systemd-bsod for presenting logged error messages full-screen, it's not appropriate for all errors

Theo de Raadt has released OpenBSD 7.5 as the newest version of this security-focused BSD operating system

The Intel open-source engineers working on the modern Xe DRM kernel graphics driver have begun looking at Heterogeneous Memory Management (HMM) support for cross-device and cross-driver scenarios as the latest exciting feature work for this still-experimental driver.

The open-source Panthor DRM driver for supporting newer Arm Mali GPUs was queued in drm-misc-next at the start of March ahead of the Linux 6.9 merge window

So far when it comes to Direct Rendering Manager (DRM) / Kernel Mode-Setting (KMS) display drivers for Linux, there are Rust efforts underway for the Apple Silicon kernel graphics driver with the Asahi Linux project as well as the new Nova effort for a modern open-source NVIDIA kernel driver from Red Hat

David Airlie has submitted all of the Direct Rendering Manager (DRM) kernel graphics/display driver updates today for Linux 6.9.
