Subject: [PATCH v2 0/3] Intel RAPL updates for Atom CPUs
Date: Fri, 7 Nov 2014 09:29:24 -0800 [thread overview]
Message-ID: <1415381367-16693-1-git-send-email-jacob.jun.pan@linux.intel.com> (raw)
Running Average Power Limit (RAPL) is supported in Atom processors
with a slightly different implementation. This patchset abstracts the
differences and add support for newer ATOM CPUs.
Intel Software Developers Manual has also been updated with many changes
and clarifications on how RAPL units and power limits are calculated.
Changes:
v2: fix 32 bit divide in time window calculation
Jacob Pan (3):
powercap/rapl: abstract per cpu type functions
powercap/rapl: handle atom and core differences
powercap/rapl: add new model ids
