Subject: [PATCH 03/12] perf stat: Fix indentation of stalled backend cycle
Date: Mon, 16 May 2016 23:45:32 -0300 [thread overview]
Message-ID: <1463453141-10144-4-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1463453141-10144-1-git-send-email-acme@kernel.org>
From: Namhyung Kim <namhyung@kernel.org>
The commit 140aeadc1fb5 ("perf stat: Abstract stat metrics printing")
changed how shadow metrics are printed, but it missed to update the
width of the stalled backend cycles event to 7.2% like others. This
resulted in misaligned output like below:
Performance counter stats for 'pwd':
0.638313 task-clock (msec) # 0.567 CPUs utilized
0 context-switches # 0.000 K/sec
0 cpu-migrations # 0.000 K/sec
54 page-faults # 0.085 M/sec
885,600 cycles # 1.387 GHz
