Subject: [PATCH 0/3 v4] powercap, intel_rapl, implement time window checks

This was submitted back in December and not picked up after review.

P.

-----8<----
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.

Prarit Bhargava (3):
  powercap, intel_rapl, implement get_max_time_window
  powercap, intel_rapl, implement check for minimum time window
  powercap, intel_rapl, Add ignore_max_time_window_check module
    parameter for broken BIOSes
