That will not necessarily help the PM QoS client in choosing the
appropriate performance level. On one platform the appropriate level for
a given situation might be 5% of max, on another 75%. I think the hairy
issue is that there are so many application oriented performance metrics
(MIPS, FLOPS, FPS, milliseconds..).
