Hi,
I am sure that user space program can't install ISR or get IRQ from
hardware directly. I'd like to know there is any way a user space
program to get waked up by a specific hardware IRQ.
I am developing some applications that use IRQ on MPC8260 board.
thanks.
willy.

Create a character device which implements the poll() method,, and use
select() in userspace.
