258 Select this option to enable more accurate task and CPU time
259 accounting. This is done by reading a CPU counter on each
260 kernel entry and exit and on transitions within the kernel
261 between system, softirq and hardirq state, so there is a
262 small performance impact. This also enables accounting of
263 stolen time on logically-partitioned systems running on
264 IBM POWER5-based machines.
