This series adds basic drm_panic support for nouveau. Patches 1-4 Add missing bits in drm_panic (ABGR2101010, set_pixel() for tiling, ...) Patch 5 registers nouveau to drm_panic, and handle tiling. I've tested on a GTX1650, while running Gnome/Wayland desktop. I didn't find documentation about nVidia tiling, so it may not work on other GPU than GTX1650. 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 CONFIG_DRM_PANIC_DEBUG and run echo 1 > /sys/kernel/debug/dri/0/drm_panic_plane_0 Best regards, -- Jocelyn Jocelyn Falempe (5): drm/panic: Add ABGR2101010 support drm/panic: only draw the foreground color in drm_panic_blit() drm/panic: Add a set_pixel() callback to drm_scanout_buffer drm/panic: add a private pointer to drm_scanout_buffer drm/nouveau: Add drm_panic support for nv50+ drivers/gpu/drm/drm_panic.c | 183 ++++++++++++++---------- drivers/gpu/drm/nouveau/dispnv50/wndw.c | 127 +++++++++++++++- include/drm/drm_panic.h | 15 ++ 3 files changed, 247 insertions(+), 78 deletions(-) base-commit: 484436ec5c2bffe8f346a09ae1cbc4cbf5e50005 -- 2.45.0
