同一台机器把perf切换回23号的版本，该用例是pass的，切换到24号的perf版本，该用例会fail；初步分析是24号开发提交的多个perf相关commit引入的问题 24号晚上编译的perf验证结果： # perf -v perf version 5.10.134-584.git.8e4c8a3e2.an8.x86_64 # perf test -v "PMU event table sanity" 10: PMU events : 10.1: PMU event table sanity : --- start --- test child forked, pid 1057896 testing event table bp_l1_btb_correct: pass testing event table bp_l2_btb_correct: pass testing event table l3_cache_rd: pass testing event table dispatch_blocked.any: pass testing event table eist_trans: pass testing event table segment_reg_loads.any: pass test child finished with -1 ---- end ---- PMU events subtest 1: FAILED! 23号晚上perf验证结果： # perf -v perf version 5.10.134-583.git.ead5e8d2a.an8.x86_64 # perf test -v "PMU event table sanity" 10: PMU events : 10.1: PMU event table sanity : --- start --- test child forked, pid 1057383 testing event table uncore_hisi_ddrc.flux_wcmd: pass testing event table unc_cbo_xsnp_response.miss_eviction: pass testing event table bp_l1_btb_correct: pass testing event table bp_l2_btb_correct: pass testing event table l3_cache_rd: pass testing event table segment_reg_loads.any: pass testing event table dispatch_blocked.any: pass testing event table eist_trans: pass test child finished with 0 ---- end ---- PMU events subtest 1: Ok
这个问题在an8 5.10.134-14_rc1内核也是存在的。 # uname -r 5.10.134-14_rc1.an8.x86_64 测试日志： 10.1: PMU event table sanity : --- start --- test child forked, pid 8774 testing event table bp_l1_btb_correct: pass testing event table bp_l2_btb_correct: pass testing event table l3_cache_rd: pass testing event table dispatch_blocked.any: pass testing event table eist_trans: pass testing event table segment_reg_loads.any: pass test child finished with -1 ---- end ---- PMU events subtest 1: FAILED!
请帮忙确认一下是不是perf的修改引入问题
由于perf metric的json文件更新，导致perf test PMU event中 “PMU event table sanity” 失败，现在更新perf test功能，将测试用例与json文件格式保持一致，以修复perf test错误的问题。 https://gitee.com/anolis/cloud-kernel/pulls/1391
已修复
最新的nightly验证通过，问题解决，bug关闭 # perf test 'PMU event table sanity' 10: PMU events : 10.1: PMU event table sanity : Ok # perf -v perf version 5.10.134-597.git.78c79f183.an8.x86_64 # uname -r 5.10.134-597.git.78c79f183.an8.x86_64
