Ideally, you should put whatever device you're trying to drive in the device tree, and use of_irq_to_resource() on the device node to find the virtual IRQ number. Failing that, you can call irq_find_mapping(), but you'll need to either pass in the device node of the relevant interrupt controller, or call irq_set_default_host() -- but really, it's better to just use the device tree. -Scott _______________________________________________ Linuxppc-dev mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-dev
