The Switch makes use of a customized NVIDIA driver.

nvdrv:a

Main NVIDIA driver service.

Cmd Name
0 Open
1 Ioctl
2 Close
3 Initialize
4 QueryEvent
5 MapSharedMem
6 ?
7 ?
8 Audio render related init?
9 ?

Ioctls

The ioctl number is generated with the following primitive (see Linux kernel): 

#define _IOC(inout, group, num, len) \
   (inout | ((len & IOCPARM_MASK) << 16) | ((group) << 8) | (num))

The following table contains known ioctls.
