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.

Platform driver for Userspace I/O devices, including generic

interrupt handling code. Shared interrupts 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.

ports instead of memory mapped I/O. In order to make it
