Sorry! For the record, I'm testing on a 2-CPU system, so I'm not sure whether your explanation applies; it talks about CPUs 2 and 3 whereas I only have CPUs 0 and 1, but perhaps your explanation applies equally to any pair of CPUs? For the record, here's the information you requested in the other email: # cat /sys/devices/system/cpu/cpu*/cpufreq/related_cpus 0 1 0 1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
