Subject: [namhyung-perf:perf/defer-callchain-v3] [perf record] 6bd89ae7d1:
perf-sanity-tests.Zstd_perf.data_compression/decompression.fail
Hello,
kernel test robot noticed "perf-sanity-tests.Zstd_perf.data_compression/decompression.fail" on:
commit: 6bd89ae7d14788ba15e25289479addcb98e7dc26 ("perf record: Make sure to update build-ID cache")
https://git.kernel.org/cgit/linux/kernel/git/namhyung/linux-perf.git perf/defer-callchain-v3
[test failed on linux-next/master b179ce312bafcb8c68dc718e015aee79b7939ff0]
in testcase: perf-sanity-tests
version:
with following parameters:
perf_compiler: gcc
group: group-02
config: x86_64-rhel-9.4-bpf
compiler: gcc-14
test machine: 16 threads 1 sockets Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz (Coffee Lake-E) with 32G memory
(please refer to attached dmesg/kmsg for entire log/backtrace)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@...el.com>
| Closes: https://lore.kernel.org/oe-lkp/202511141407.f9edcfa6-lkp@intel.com
one thing we observed is the test still can pass sometimes. as below, upon
6bd89ae7d1, the tests failed 14 times out of 20 runs, but those other 6 runs
really pass, the log is just same as parent, which can always pass.
