perf report: Sort by sampled cycles percent per block for tui
Previous patch has implemented a new option "--total-cycles". But only stdio mode is supported. This patch supports the tui mode and support '--percent-limit'. For example, perf record -b ./div perf report --total-cycles --percent-limit 1 # Samples: 2753248 of event 'cycles' Sampled Cycles% Sampled Cycles Avg Cycles% Avg Cycles [Program Block Range] Shared Object 26.04% 2.8M 0.40% 18 [div.c:42 -> div.c:39] div 15.17% 1.2M 0.16% 7 [random_r.c:357 -> random_r.c:380] libc-2.27.so 5.11% 402.0K 0.04% 2 [div.c:27 -> div.c:28] div 4.87% 381.6K 0.04% 2 [random.c:288 -> random.c:291] libc-2.27.so 4.53% 381.0K 0.04% 2 [div.c:40 -> div.c:40] div 3.85% 300.9K 0.02% 1 [div.c:22 -> div.c:25] div 3.08% 241.1K 0.02% 1 [rand.c:26 -> rand.c:27] libc-2.27.so 3.06% 240.0K 0.02% 1 [random.c:291 -> random.c:291] libc-2.27.so 2.78% 215.7K 0.02% 1 [random.c:298 -> random.c:298] libc-2.27.so 2.52% 198.3K 0.02% 1 [random.c:293 -> random.c:293] libc-2.27.so 2.36% 184.8K 0.02% 1 [rand.c:28 -> rand.c:28] libc-2.27.so 2.33% 180.5K 0.02% 1 [random.c:295 -> random.c:295] libc-2.27.so 2.28% 176.7K 0.02% 1 [random.c:295 -> random.c:295] libc-2.27.so 2.20% 168.8K 0.02% 1 [rand@plt+0 -> rand@plt+0] div 1.98% 158.2K 0.02% 1 [random_r.c:388 -> random_r.c:388] libc-2.27.so 1.57% 123.3K 0.02% 1 [div.c:42 -> div.c:44] div 1.44% 116.0K 0.42% 19 [random_r.c:357 -> random_r.c:394] libc-2.27.so -------------------------------------------------- v7: --- 1. Since we have used use_browser in report__browse_block_hists to support stdio mode, now we also add supporting for tui. 2. Move block tui browser code from ui/browsers/hists.c to block-info.c. v6: --- Create report__tui_browse_block_hists in block-info.c (codes are moved from builtin-report.c). v5: --- Fix a crash issue when running perf report without '--total-cycles'. The issue is because the internal flag is renamed from 'total_cycles' to 'total_cycles_mode' in previous patch but this patch still uses 'total_cycles' to check if the '--total-cycles' option is enabled, which causes the code to be inconsistent. v4: --- Since the block collection is moved out of printing in previous patch, this patch is updated accordingly for tui supporting. v3: --- Minor change since the function name is changed: block_total_cycles_percent -> block_info__total_cycles_percent Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Reviewed-by: Jiri Olsa <jolsa@kernel.org> 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: Jin Yao <yao.jin@intel.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20191107074719.26139-8-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
