This series adds basic drm_panic support for nouveau. Patches 1-2 Add missing bits in drm_panic (ABGR2101010, private data for set_pixel()) Patch 3 registers nouveau to drm_panic, and handle tiling. I've tested on a GTX1650, while running Gnome/Wayland desktop. It should work on other nv50+ cards, but I didn't test them. To test it, you need to build your kernel with CONFIG_DRM_PANIC=y, and run: echo c > /proc/sysrq-tr...
