select DRM_LEGACY
default y
help
There was a version of the nouveau DDX that relied on legacy
ctx ioctls not erroring out. But that was back in time a long
ways, so offer a way to disable it now. For uapi compat with
old nouveau ddx this should be on by default, but modern distros
should consider turning it off.

Support for Nouveau platform driver, used for SoC GPUs as found
on NVIDIA Tegra K1.
config NOUVEAU_DEBUG

help
Selects the maximum debug level to compile support for.
0 - fatal
1 - error
2 - warning
3 - info
4 - debug
5 - trace (recommended)
6 - paranoia
7 - spam
The paranoia and spam levels will add a lot of extra checks which
may potentially slow down driver operation.
