| |
From: Andi Kleen <ak@linux.intel.com>
When --metric-only is enabled there were no headers for the topology in interval mode. Fix this here.
Before
$ perf stat --metric-only -e cycles,instructions -a -I 1000 1.000554967 insn per cycle stalled cycles per insn 1.000554967 0.27 2.000862000 0.24 3.001354948 0.25
After
$ perf stat --metric-only -e cycles,instructions -a -I 1000 1.000554967 insn per cycle stalled cycles per insn 1.000554967 0.27 2.000862000 0.24 3.001354948 0.25
