Hi,
is there an "official" way of obtaining the current tick rate when
CONFIG_NO_HZ? This is for a simple statistics display tool. Counting the
interrupts from /proc/interrupts (calculating the difference between two
timepoints) seems to work, though I have seen at least one x86 machine
where both IRQ0 and the LOC counters increase, making it not entirely
obvious which number to take as a base. Suggestions?
