Hi Daniel,

Interesting idea.

The benefit of this patch is to reduce power.
Have you been able to measure a power reduction, via power meter, or
via built-in RAPL power meter?
(turbostat will show RAPL watts, or if you have constant quantity of
work, use turbostat -J)

Hi Len,

thanks for looking the patches.

I will tweak, respin the patchset and do some more measurements.

I don't have a power meter but may be the RAPL could help to test on x86.
