Hi, I have seen this config option on x86 as well as many other architectures. I could not find any documentation on what this option exactly is. I do understand IRQ's in general context, but support of sparse_irq's is still a little vague for me. Could anyone here shed some light on it. - Doug _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
