Subject: [PATCH] powercap/rapl: lower warning level for domain detection
Date: Thu, 28 Aug 2014 21:56:08 -0700	[thread overview]
Message-ID: <1409288168-6537-1-git-send-email-jacob.jun.pan@linux.intel.com> (raw)

Many CPUs do not support complete set of RAPL domains, as a
result this detection failed message is very misleading and
annoying. So lower the warning message to info and reword.
