This series adds basic drm_panic support for nouveau. Patches 1 Add ABGR2101010 support in drm_panic. Patch 2 registers nouveau to drm_panic, and handle tiling. I've tested on a GTX1650 (Turing) and GF 8800 GT (Tesla), while running Gnome/Wayland desktop, and in VT. It should work on other nv50+ cards, but I didn't test them. To test it, you need to build your kernel with

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,
