When debugging the tui browser I find it useful to redirect the debug log into a file. Currently it's always forced to the message line. Add an option to force it to stderr. Then it can be easily redirected. Example: [root@zoo ~]# perf --debug stderr report -vv 2> /tmp/debug [root@zoo ~]# tail /tmp/debug dso open failed, mmap: No such file or directory dso open failed, mmap: No such file or directory dso open failed, mmap: No such file or directory dso open failed, mmap: No such file or directory dso open failed, mmap: No such file or directory Using /root/.debug/.build-id/4e/841948927029fb650132253642d5dbb2c1fb93 for symbols Failed to open /tmp/perf-8831.map, continuing without symbols Failed to open /tmp/perf-12721.map, continuing without symbols Failed to open /tmp/perf-6966.map, continuing without symbols Failed to open /tmp/perf-8802.map, continuing without symbols [root@zoo ~]# Signed-off-by: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/1416605880-25055-2-git-send-email-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
