When libtraceevent parses format fields, it assumes that array of 1 byte is string but it's not always true. The kvm_emulate_insn contains 15 u8 array of insn that contains (binary) instructions. Thus when it's printed, it'll have broken output like below: kvm_emulate_insn: [FAILED TO PARSE] rip=3238197797 csbase=0 len=2 \ insn=<89>P^]<B4>& flags=5 failed=0 With this patch: kvm_emulate_insn: [FAILED TO PARSE] rip=3238197797 csbase=0 len=2 \ insn=ARRAY[89, 10, 5d, c3, 8d, b4, 26, 00, 00, 00, 00, 55, 89, e5, 3e] flags=5 failed=0 Suggested-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/r/1340352615-20737-2-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
