Enable this to allow the userspace driver core code to be

built. This code allows userspace programs easy access to
|
|
kernel interrupts and memory locations, allowing some drivers
|
|
to be written in userspace. Note that a small kernel driver
|
|
is also required for interrupt handling to work properly.

If you don't know what to do here, say N.

Platform driver for Userspace I/O devices, including generic

This kernel driver requires that the matching userspace driver

handles interrupts in a special way. Userspace is responsible
|
|
for acknowledging the hardware device if needed, and re-enabling
|
|
interrupts in the interrupt controller using the write() syscall.

Memory regions can be specified with the same platform device

resources as the UIO_PDRV drivers, but dynamic regions can also

be specified.

The number and size of these regions is static,

the associated device file is opened. The

memory is freed once the uio device is closed.

UIO driver for the Adrienne Electronics Corporation PCI time

code device.

This device differs from other UIO devices since it uses I/O
|
|
ports instead of memory mapped I/O. In order to make it
|
|
possible for UIO to work with this device a utility, uioport,
|
|
can be used to read and write the ports:

git clone git://ifup.org/philips/uioport.git
