Jin Yao 04d2600ab6 perf annotate: Display all available events on --stdio ... When we perform the following command lines: $ perf record -e "{cycles,branches}" ./div $ perf annotate main --stdio The output shows only the first event, "cycles" and the displaying format is not correct. Percent | Source code & Disassembly of div for cycles (44550 samples) ----------------------------------------------------------------------------------- : : : : Disassembly of section .text: : : 00000000004004b0 <main>: : main(): : : return i; : } : : int main(void) : { 0.00 : 4004b0: push %rbx : int i; : int flag; : volatile double x = 1212121212, y = 121212; : : s_randseed = time(0); 0.00 : 4004b1: xor %edi,%edi : srand(s_randseed); 0.00 : 4004b3: mov $0x77359400,%ebx : : return i; : } The issue is that the value of the 'nr_percent' variable is hardcoded to 1. This patch fixes it. With this patch, the output is: Percent | Source code & Disassembly of div for cycles (44550 samples) ----------------------------------------------------------------------------------- : : : : Disassembly of section .text: : : 00000000004004b0 <main>: : main(): : : return i; : } : : int main(void) : { 0.00 0.00 : 4004b0: push %rbx : int i; : int flag; : volatile double x = 1212121212, y = 121212; : : s_randseed = time(0); 0.00 0.00 : 4004b1: xor %edi,%edi : srand(s_randseed); 0.00 0.00 : 4004b3: mov $0x77359400,%ebx : : return i; : } Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Fixes: f681d593d1 ("perf annotate: Remove disasm__calc_percent() from disasm_line__print()") Link: http://lkml.kernel.org/r/1525881435-4092-1-git-send-email-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2018-05-10 15:19:30 -03:00
