search for: ilut

The hardware supports either size. Also add checks to ensure that only these two sizes may be used for supplying a LUT. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- Only tested on G84 and GK208. The GV100+ is entirely untested. With the fixed modetest tool, setting ilut and olut sizes to different quantities seems to work out OK, across a range of formats (XR24, XB30, XB4H). drivers/gpu/drm/nouveau/dispnv50/base907c.c | 11 ++++++++--- drivers/gpu/drm/nouveau/dispnv50/head.c | 14 +++++++++----- drivers/gpu/drm/nouveau/dispnv50/head.h | 7 ++++--- drive...

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,
