6 Enable this to allow the userspace driver core code to be
7 built. This code allows userspace programs easy access to
8 kernel interrupts and memory locations, allowing some drivers
9 to be written in userspace. Note that a small kernel driver
10 is also required for interrupt handling to work properly.

31 Platform driver for Userspace I/O devices, including generic
32 interrupt handling code. Shared interrupts are not supported.
33
34 This kernel driver requires that the matching userspace driver
35 handles interrupts in a special way. Userspace is responsible
36 for acknowledging the hardware device if needed, and re-enabling
37 interrupts in the interrupt controller using the write() syscall.

48 Memory regions can be specified with the same platform device
49 resources as the UIO_PDRV drivers, but dynamic regions can also
50 be specified.
51 The number and size of these regions is static,
52 but the memory allocation is not performed until
53 the associated device file is opened. The
54 memory is freed once the uio device is closed.
