Its basically not possible to do with most hardware because you get deadlocks when there are shared interrupts.
However see drivers/uio in the current GIT tree (or recent -mm kernels), that assumes you write a truely minimal IRQ handler/board driver in the kernel and it then exposes the memory spaces and IRQ stream to user space. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
