From 429a5f9d89fc52256b2a59cd1277afbfafb739b3 Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Thu, 20 Feb 2020 09:36:14 +0800 Subject: perf report: Allow specifying event to be used as sort key in --group output When performing "perf report --group", it shows the event group information together. By default, the output is sorted by the first event in group. It would be nice for user to select any event for sorting. This patch introduces a new option "--group-sort-idx" to sort the output by the event at the index n in event group. For example, Before: # perf report --group --stdio # To display the perf.data header info, please use --header/--header-only options. # # # Total Lost Samples: 0 # # Samples: 12K of events 'cpu/instructions,period=2000003/, cpu/cpu-cycles,period=200003/, BR_MISP_RETIRED.ALL_BRANCHES:pp, cpu/event=0xc0,umask=1,cmask=1, # Event count (approx.): 6451235635 # # Overhead Command Shared Object Symbol # ................................ ......... ....................... ................................... # 92.19% 98.68% 0.00% 93.30% mgen mgen [.] LOOP1 3.12% 0.29% 0.00% 0.16% gsd-color libglib-2.0.so.0.5600.4 [.] 0x0000000000049515 1.56% 0.03% 0.00% 0.04% gsd-color libglib-2.0.so.0.5600.4 [.] 0x00000000000494b7 1.56% 0.01% 0.00% 0.00% gsd-color libglib-2.0.so.0.5600.4 [.] 0x00000000000494ce 1.56% 0.00% 0.00% 0.00% mgen [kernel.kallsyms] [k] task_tick_fair 0.00% 0.15% 0.00% 0.04% perf [kernel.kallsyms] [k] smp_call_function_single 0.00% 0.13% 0.00% 6.08% swapper [kernel.kallsyms] [k] intel_idle 0.00% 0.03% 0.00% 0.00% gsd-color libglib-2.0.so.0.5600.4 [.] g_main_context_check 0.00% 0.03% 0.00% 0.00% swapper [kernel.kallsyms] [k] apic_timer_interrupt ...
