0006 Enable this to allow the userspace driver core code to be
0007 built. This code allows userspace programs easy access to
0008 kernel interrupts and memory locations, allowing some drivers
0009 to be written in userspace. Note that a small kernel driver
0010 is also required for interrupt handling to work properly.

0033
0034 This kernel driver requires that the matching userspace driver
0035 handles interrupts in a special way. Userspace is responsible
0036 for acknowledging the hardware device if needed, and re-enabling
0037 interrupts in the interrupt controller using the write() syscall.

0048 Memory regions can be specified with the same platform device
0049 resources as the UIO_PDRV drivers, but dynamic regions can also
0050 be specified.
0051 The number and size of these regions is static,
0052 but the memory allocation is not performed until
0053 the associated device file is opened. The
0054 memory is freed once the uio device is closed.
