To avoid the funny: [root@doppio ~]# perf record -a -f sleep 2s [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.334 MB perf.data (~14572 samples) ] [root@doppio ~]# perf report --no-call-graph selected -g but no callchain data. Did you call perf record without -g? And fix the bug reported by peterz when we do indeed record with callchains and then ask for a report without: [root@doppio ~]# perf record -a -g -f sleep 2s [root@doppio ~]# perf report --no-call-graph Segmentation fault [root@doppio ~]# Reported-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frédéric Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> LKML-Reference: <1262699685-27820-1-git-send-email-acme@infradead.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> |
