We have noticed perf (OE recipe) build failure on linux next 20191022.
do you see this failure ?

I tested for two methods with linux-next, one is native building mode
for Arm64 building on DB410c board, another is cross compiling Arm64
binary on my x86 laptop.  Both cannot reproduce this failure.

After read your shared build log and I think the building process is
expected: Perf tool tries to build libbpf, so it changes to the
building folder 'BPF_DIR' (which is under $(srctree)/tools/lib/bpf/),
then failed to find file $(srctree)/scripts/bpf_helpers_doc.py.

Here $(srctree) means the kernel's root folder.

Seems to me, this failure is caused by missing to sync kernel files
$linux_src/scripts to the OE folder 'perf/1.0-r9/perf-1.0/scripts'?

Thanks,
Leo Yan

Yes, this is exactly the reason. As of e01a75c159691 (merged on
next-20191022), we need to include linux/scripts into the source
directory for OpenEmbedded to build Perf. We have now sent a fix to
OE-core.

By the way, while looking at this, we found this unresolved conflict
in the tree:
