I agree. Isn't this exactly what HZ=1000 with VST achieves?

Having run VST on ARM, VST must be disabled while the bogomips calibrations have completed - I suspect VST requires some sort of enable/disable counted system like we do for interrupts and the hlt thing, so that the hotplug CPU code can do it's bogomips calibration appropriately. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
