Enable this
to allow the userspace driver core
code to be
built. This
code allows userspace programs easy
access to
kernel interrupts

to be written
in userspace. Note that a small kernel driver
is also required
for interrupt handling
to work properly.

all of the heavy lifting

Platform driver
for Userspace I/O devices, including generic
interrupt handling
code. Shared interrupts
are not supported.
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.
If you don

Platform driver

are not supported.
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,
but the
memory allocation
is not performed
until
the associated device
file is opened. The
memory is freed once the uio device
is closed.

UIO driver
for the Adrienne Electronics Corporation PCI

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
If you compile this as a module, it will be called uio_aec.
