DRM_Panic is the functionality first added in Linux 6.10 for "Blue Screen of Death" type functionality when a kernel panic occurs or similar for displaying a nice graphical error message. Since the initial introduction it's been extended to handle QR code error messages , monochrome logos , and other customization options. The AMDGPU driver has new patches available for expanding the DRM_Panic support to all DCE/DCN-based graphics cards.

DRM_Panic requires support on the part of the Direct Rendering Manager (DRM) driver and was initially limited to a few basic drivers. Since then DRM_Panic support has been extended to the more prominent kernel graphics/display drivers. Recently there's been work on DRM_Panic for the AMDGPU driver . AMDGPU maintainer Alex Deucher this week now posted a patch-set for allowing DRM_Panic on all modern AMD graphics processors making use of the DCE/DCN display IP.

This patch series builds on the earlier AMDGPU DRM_Panic patches to get this panic support working for all DCE/DCN variants and code paths. We'll see if it gets picked up in time for the upcoming Linux v6.13 merge window.
