We actually only added that recently, in c54b2bf1b5e9 "powerpc: Add ppc64 hard lockup detector support". AFAICS it doesn't actually have anything to do with the NMI behaviour of the perf interrupt. It controls whether the hardlockup detector is enabled and/or the oprofile NMI timer. cheers _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
