IRQs

hey everybody, is there an easy guide to use IP core's IRQ in uClinux? do I need an interrupt handler or read from a specific location? thanks :)

The normal way to handle IRQs is doing a Kernel driver. As the OS handle the ISR entry and exit for you, here, the C code you do is not different from what is done with other architectures. There are lot of examples in the Kernel sources.

Is that what you want to do ?

I learned that "uio" should allow for a kind of ISR in s user land application, but I never did look into that.
