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. I've tested on GTX1650 (Turing), GeForce GT 1030 (Pascal) and Geforce 8800 GTS (Tesla), 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 CONFIG_DRM_PANIC=y, and run: echo c > /proc/sysrq-trigger or you can enable
