Subject: perf report --no-children chopping off tracepoint fields
Date: Thu, 7 Apr 2016 11:51:12 -0300	[thread overview]
Message-ID: <20160407145112.GG5945@kernel.org> (raw)

Hi Namhyung,

	If I do:

  # perf record --call dwarf -p 2519 -e syscalls:sys_enter_open

And then run plain 'perf report' I get this on the TUI, perfect:

  Samples: 1  of event 'syscalls:sys_enter_open', Event count (approx.): 1
  Children      Self  Trace output
+  100.00%   100.00%  filename: 0x7efe0cc9a96a, flags: 0x00000000, mode: 0x7fffa3da07f0

But if I use 'perf report --no-children' I get it chopped off at the
start of the first tp arg value:

 Samples: 1  of event 'syscalls:sys_enter_open', Event count (approx.): 1
  Overhead  Trace output
+  100.00%  filename: 0x 

:-\
