Subject: [PATCH 8/9] perf report: Fix --stdio output alignment when --showcpuutilization used
Date: Sun, 8 Jan 2012 13:42:18 -0200 [thread overview]
Message-ID: <1326037339-31125-9-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1326037339-31125-1-git-send-email-acme@infradead.org>
From: Namhyung Kim <namhyung@gmail.com>
Current perf report output is broken if --showcpuutilization is used.
Combination with -n and/or --show-total-period make things worse.
This patch fixes it as follows:
before:
48.25% 48.25% 0.00% sleep [kernel.kallsyms] [k] trace_hardirqs_off
34.99% 34.99% 0.00% sleep [kernel.kallsyms] [k] __find_get_block_slow
15.99% 15.99% 0.00% sleep [kernel.kallsyms] [k] lock_release_holdtime
0.77% 0.77% 0.00% sleep [kernel.kallsyms] [k] native_write_msr_safe
after:
48.25% 48.25% 0.00% sleep [kernel.kallsyms] [k] trace_hardirqs_off
34.99% 34.99% 0.00% sleep [kernel.kallsyms] [k] __find_get_block_slow
15.99% 15.99% 0.00% sleep [kernel.kallsyms] [k] lock_release_holdtime
0.77% 0.77% 0.00% sleep [kernel.kallsyms] [k] native_write_msr_safe
