Just like we have in the histograms browser used as the main screen for 'perf top --tui' and 'perf report --tui', to print the current annotation to a file with a named composed by the symbol name and the ".annotation" suffix. Here is one example of pressing 'A' on 'perf top' to live annotate a kernel function and then press 'P' to dump that annotation, the resulting file: # cat _raw_spin_lock_irqsave.annotation _raw_spin_lock_irqsave() /proc/kcore Event: cycles:ppp 7.14 nop 21.43 push %rbx 7.14 pushfq pop %rax nop mov %rax,%rbx cli nop xor %eax,%eax mov $0x1,%edx 64.29 lock cmpxchg %edx,(%rdi) test %eax,%eax ↓ jne 2b mov %rbx,%rax pop %rbx ← retq 2b: mov %eax,%esi → callq queued_spin_lock_slowpath mov %rbx,%rax pop %rbx ← retq # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jin Yao <yao.jin@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-zzmnrwugb5vtk7bvg0rbx150@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
