Hi,
perf archive has some waring messages, is this a bug?
root@intel-s3e36-01 perf]# ./perf-archive
tar: .build-id/b2/370e39ea2898c6e11c188e2f3879e4e3d6d1ef: Cannot stat: No such file or directory
tar: .build-id/b2/370e39ea2898c6e11c188e2f3879e4e3d6d1ef: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
Now please run:
$ tar xvf perf.data.tar.bz2 -C ~/.debug
wherever you need to run 'perf report' on.

kernel.kallsyms is not created successfully in the buildid-cache.

Did you re-run perf command?
Need to re-run it to generate kernel.kallsyms build-id cache.
For example,
$ perf record -- sleep 3
$ perf-archive
If the problem is still there, please attach below output:
$ tree ~/.debug
