### nouveau_noop backend
|
||||
|
||||
This implements the minimum of nouveau in order to make shader-db work.
|
||||
The submit ioctl is stubbed out to not execute anything.
|
||||
|
||||
Export `MESA_LOADER_DRIVER_OVERRIDE=nouveau
|
||||
LD_PRELOAD=$prefix/lib/libnouveau_noop_drm_shim.so`.
|
||||
|
||||
By default, GK110 is exposed. The chip can be selected with an environment
|
||||
variable like `NOUVEAU_CHIPSET=f0`. Some chips of note with the appropriate
|
||||
chipset ids:
