From fcdf1797e1f8f6605b194e620a333e6d47e07672 Mon Sep 17 00:00:00 2001 From: Jacob Pan Date: Tue, 2 Sep 2014 02:55:21 -0700 Subject: [PATCH] powercap / RAPL: change domain detection message Many CPUs do not support complete set of RAPL domains, as a result this detection failed message is very misleading and can be annoying. [ 5.082632] intel_rapl: RAPL domain core detection failed [ 5.088370] intel_rapl: RAPL domain uncore detection failed So lower the warning message to info and only print out the RAPL domains that are supported.
