I vaguely remember mention on this list of a tool that soaks up as many cycles as it can get to obtain an accurate measurement of the true system time. Can some one give me a pointer? I've had no luck with Google... thanks, Torrey Hoffman thoffman@arnor.net torrey.hoffman@myrio.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
