Commit ed21d6d7c48e6e ("perf tests: Add test for PE binary format support")
adds a WINDOWS EXE file named tests/pe-file.exe, which is
examined by the test case 'PE file support'. As powerpc doesn't support
it, we are skipping this test.
Result in power9 platform before this patach:
[command]# ./perf test -F 68
68: PE file support : Failed!
Result in power9 platform after this patch:
[command]# ./perf test -F 68
68: PE file support : Skip

But why is it failing? I.e. what is that
perf test -v -F 68
outputs?
Using 'perf report' on a perf.data file containing samples in such
binaries, collected on x86 should work on whatever workstation a
developer uses.
Say, on a MacBook aarch64 one can look at a perf.data file collected on
a x86_64 system where Wine running a PE binary was present.

Hi
What is the distro you are using?
I observed the same issue on s390 but this was fixed for fedora33 somehow.
The error just went away after a dnf update....
[root@m35lp76 perf]# cat /etc/fedora-release
Fedora release 33 (Thirty Three)
[root@m35lp76 perf]# ./perf test -F 68
68: PE file support : Ok
[root@m35lp76 perf]#
However on my fedora32 machine it still fails:
[root@t35lp46 perf]# cat /etc/fedora-release
Fedora release 32 (Thirty Two)
[root@t35lp46 perf]# ./perf test -F 68
68: PE file support : FAILED!
[root@t35lp46 perf]#
Note that I am running the same kernel on both machines: linux 5.10.0rc7 downloaded
this morning.
