To configure your coprocessor proper, we need a translation mechanism from the linux interrupt number to the magic value which needs to be written into the trigger register when the coprocessor wants to send an interrupt or an IPI. int irq_get_irq_hwcfg(unsigned int irq, struct irq_hwcfg *cfg); struct irq_hwcfg needs to be defined, but it might look like this: { /* Generic fields */ x; ... union { mips_gic; ... }; };That function provides you the information which you have to hand over to your coprocessor firmware.
Of course! * me slapping myself on the back * Thanks, Qais
