perf report/top: Add --raw-trace option
The --raw-trace option allows disabling pretty printing by the event's print_fmt or plugin. Besides that, each dynamic sort key now can receive a 'raw' suffix separated by '/' to ask for the raw trace of a specific field. $ perf report -s comm,kmem:kmalloc.gfp_flags ... # Overhead Command gfp_flags # ........ ....... ................... # 99.89% perf GFP_NOFS|GFP_ZERO 0.06% sleep GFP_KERNEL 0.03% perf GFP_KERNEL|GFP_ZERO 0.01% perf GFP_KERNEL Now $ perf report -s comm,kmem:kmalloc.gfp_flags --raw-trace or $ perf report -s comm,kmem:kmalloc.gfp_flags/raw ... # Overhead Command gfp_flags # ........ ....... .......... # 99.89% perf 32848 0.06% sleep 208 0.03% perf 32976 0.01% perf 208 Suggested-and-Acked-by: Jiri Olsa <jolsa@redhat.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1450804030-29193-9-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
