IA64 got ftrace support a while ago, but recently ftrace grew a dependency on CONFIG_STACKTRACE_SUPPORT and CONFIG_TRACE_IRQFLAGS_SUPPORT so it happens to be disabled in current mainline. Interestingly those two dependencies are also the same that are required for lockdep, which means IA64 never supported lockdep (quite scary, eh?) I found an old patch from Luming Yu to implement lockdep on IA64, but it didn't get anywhere: http://www.gelato.unsw.edu.au/archives/linux-ia64/0712/21510.html Any chance someone could look into resurrecting it or at least the support functionality for ftrace? -- To unsubscribe from this list: 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
