- Choose this option if you want kernel modesetting enabled by default,
- and you have a new enough userspace to support this. Running old
- userspaces with this enabled will cause pain.
+ Choose this option if you want kernel modesetting enabled by default.
+
+ This is a completely new driver. It's only part of the existing drm
+ for compatibility reasons. It requires an entirely different graphics
+ stack above it and works very differently from the old drm stack.
+ i.e. don't enable this unless you know what you are doing it may
+ cause issues or bugs compared to the previous userspace driver stack.
When kernel modesetting is enabled the IOCTL of radeon/drm
driver are considered as invalid and an error message is printed
