The + * simple math is: jiff = (sec * NSEC_PER_SEC) / NSEC_PER_JIFFIE; We + * observe that (NSEC_PER_SEC / NSEC_PER_JIFFIE) is a constant which we + * might calculate at compile time, however, the result will only have + * about 3-4 bits of precision (less for smaller values of HZ). + * + * So, we scale as follows: + * jiff = (sec) * (NSEC_PER_SEC / NSEC_PER_JIFFIE); + * jiff = ((sec) * ((NSEC_PER_SEC * SCALE)/ NSEC_PER_JIFFIE)) / SCALE; + * Then we make SCALE a power of two so: + * jiff = ((sec) * ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE)) >> SCALE; + * Now we define: + * #define SEC_CONV = ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE)) + * jiff = (sec * SEC_CONV) >> SCALE; + * + * Often the math we use will expand beyond 32-bits so we tell C how to + * do this and pass the 64-bit result of the mpy through the ">> SCALE" + * which should take the result back to 32-bits. We want this expansion + * to capture as much precision as possible. At the same time we don't + * want to overflow so we pick the SCALE to avoid this. In this file, + * that means using a different scale for each range of HZ values (as + * defined in timex.h). + * + * For those who want to know, gcc will give a 64-bit result from a "*" + * operator if the result is a long long AND at least one of the + * operands is cast to long long (usually just prior to the "*" so as + * not to confuse it into thinking it really has a 64-bit operand, + * which, buy the way, it can do, but it takes more code and at least 2 + * mpys). + + * We also need to be aware that one second in nanoseconds is only a + * couple of bits away from overflowing a 32-bit word, so we MUST use + * 64-bits to get the full range time in nanoseconds. + + */ + +/* + * Here are the scales we will use.
