Subject: [PATCH 0/3 v2] powercap, intel_rapl, implement time window checks
Date: Mon, 21 Dec 2015 09:50:00 -0500	[thread overview]
Message-ID: <1450709403-780-1-git-send-email-prarit@redhat.com> (raw)
In-Reply-To: <1450184532-21150-1-git-send-email-prarit@redhat.com>

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

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
