From: Andi Kleen Date: Tue, 1 Sep 2015 22:52:46 +0000 (-0700) Subject: perf stat: Quieten failed to read counter message X-Git-Tag: v4.14-rc1~4450^2~50^2~25 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=245bad8eb45fca36638da53fb0a361397a707001;p=platform%2Fkernel%2Flinux-rpi.git perf stat: Quieten failed to read counter message Since 3b3eb0445 running perf stat on a system without backend-stalled-cycles spits out ugly warnings by default. Since that is quite common, make the message a debug message only. We know anyways that the counter wasn't read by the normal output.
