[PATCH 0/3] powercap, intel_rapl, implement time window checks

From: Prarit Bhargava
Date: Thu Jan 21 2016 - 11:15:49 EST

Try #2 at this ....



The Intel ASDM provides a maximum time window that can be specified when
setting a time window in the RAPL driver. While the ASDM doesn't explicitly
provide a minimum time window value, it does provide a minimum time window
unit that also can be used as a minimum value.

This patchset implements barrier checking for the time windows, and adds
reporting of a known bug in which the maxmimum time window value may be
erroneously set to 0, as well as a module parameter to avoid the maximum
window checks on broken BIOSes.

[v2]: update 3/3 with minor changes
