perf trace: Simplify '--summary' output
The output of 'perf trace --summary' tries to be too cute with formatting and makes it very hard to read. Simplify it in the spirit of "strace -c": [penberg@localhost libtrading]$ perf trace -a --duration 10000 --summary -- sleep 1 ^C Summary of events: dbus-daemon (555), 10 events, 0.0%, 0.000 msec msec/call syscall calls min avg max stddev --------------- -------- -------- -------- -------- ------ sendmsg 2 0.002 0.005 0.008 55.00 recvmsg 2 0.002 0.003 0.005 44.00 epoll_wait 1 0.000 0.000 0.000 0.00 NetworkManager (667), 56 events, 0.0%, 0.000 msec msec/call syscall calls min avg max stddev --------------- -------- -------- -------- -------- ------ poll 2 0.000 0.002 0.003 100.00 sendmsg 10 0.004 0.007 0.016 15.41 recvmsg 16 0.002 0.003 0.005 8.24 zfs-fuse (669), 4 events, 0.0%, 0.000 msec msec/call syscall calls min avg max stddev --------------- -------- -------- -------- -------- ------ futex 2 0.000 0.001 0.002 100.00 Signed-off-by: Pekka Enberg <penberg@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> Link: http://lkml.kernel.org/r/1384267334-18953-1-git-send-email-penberg@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
