[lkp] [perf/core] 17fcdff68f: +86.7% aim9.brk_test.ops_per_sec

by kernel test robot

Hi, Kan, We finally enabled the Intel internal tree testing and reporting support. This is the first performance report for Intel internal git trees. The report is for performance increase so is a good news in general. But a dmesg.xz on i386 platform with kernel bug about perf is found too. The dmesg is attached with the email. That may be not related to your patch, please take a look. FYI, we noticed the below changes on ssh://lab_lkp@git-amr-3.devtools.intel.com:29418/kan_lkp-lkp lkp commit 17fcdff68f9a69f8beb7600c0803c12efed503f1 ("perf/core: find auxiliary events in running pmus
