I just fixed this today. Now it compiles fine on IA64. I also started looking into using the same technique on i386. It is very easy. It looks like opcontrol or ophelp would need to be updated. I think the trick is to make sure that ophelp knows the PMU mapping used by perfmon2, i.e., knows that PERFEVTSEL0 is PMC0 for instance. -- -Stephane - : send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
