hi, i am trying to measure kernel time using rdtsc instruction. but it returns erroneous readings, because it does not get the time from the same processor all the time. can you help me to figure out a better way of measuring time in dual processor machines? thanks od. -- Kernelnewbies: Help each other learn about the Linux kernel.
