From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnaldo Carvalho de Melo Subject: [PATCH 09/24] perf stat: Align the output for interval aggregation mode Date: Wed, 25 Mar 2020 09:41:09 -0300 Message-ID: <20200325124124.32648-10-acme@kernel.org> References: <20200325124124.32648-1-acme@kernel.org> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20200325124124.32648-1-acme@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Ingo Molnar , Thomas Gleixner Cc: Jiri Olsa , Namhyung Kim , Clark Williams , linux-kernel@vger.kernel.org, linux-perf-users@vger.kernel.org, Jin Yao , Arnaldo Carvalho de Melo , Alexander Shishkin , Andi Kleen , Kan Liang , Peter Zijlstra List-Id: linux-perf-users.vger.kernel.org From: Jin Yao There is a slight misalignment in -A -I output. For example: # perf stat -e cpu/event=cpu-cycles/ -a -A -I 1000 # time CPU counts unit events 1.000440863 CPU0 1,068,388 cpu/event=cpu-cycles/ 1.000440863 CPU1 875,954 cpu/event=cpu-cycles/ 1.000440863 CPU2 3,072,538 cpu/event=cpu-cycles/ 1.000440863 CPU3 4,026,870 cpu/event=cpu-cycles/ 1.000440863 CPU4 5,919,630 cpu/event=cpu-cycles/ 1.000440863 CPU5 2,714,260 cpu/event=cpu-cycles/ 1.000440863 CPU6 2,219,240 cpu/event=cpu-cycles/ 1.000440863 CPU7 1,299,232 cpu/event=cpu-cycles/ The value of counts is not aligned with the column "counts" and the event name is not aligned with the column "events". With this patch, the output is, # perf stat -e cpu/event=cpu-cycles/ -a -A -I 1000 # time CPU counts unit events 1.000423009 CPU0 997,421 cpu/event=cpu-cycles/ 1.000423009 CPU1 1,422,042 cpu/event=cpu-cycles/ 1.000423009 CPU2 484,651 cpu/event=cpu-cycles/ 1.000423009 CPU3 525,791 cpu/event=cpu-cycles/ 1.000423009 CPU4 1,370,100 cpu/event=cpu-cycles/ 1.000423009 CPU5 442,072 cpu/event=cpu-cycles/ 1.000423009 CPU6 205,643 cpu/event=cpu-cycles/ 1.000423009 CPU7 1,302,250 cpu/event=cpu-cycles/ Now output is aligned.
