This part's easy -- the external IRQ is used as the mpic interrupt number as-is (internal IRQs start at 16). > Once that's done, you seem to have grasped the interrupt map... for any > device or slot, you provide the mapping between idsel/pirq line on one side, > and mpic interrupt & sense on the other.

No, those correspond to the EXT1-4 that are the other side of the #ifdef for this board in arch/ppc. :-) -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
