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 <unsupported> output. Signed-off-by: Andi Kleen <> Acked-by: Jiri Olsa <> Link: Signed-off-by: Arnaldo Carvalho de Melo <>
