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 Cc: Ingo Molnar <mingo@elte.hu> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1325957132-10600-8-git-send-email-namhyung@gmail.com Signed-off-by: Namhyung Kim <namhyung@gmail.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
