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'?

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: -----8<----------8<----------8<----- $ git show 2b5d5b1927a8c commit 2b5d5b1927a8c17bf3ce5b4f781c6ba11e02cadd Merge: c1e45431c592 ae79d5588a04 Author: Ingo Molnar <mingo@kernel.org> Date: Mon Oct 21 07:13:15 2019 +0200 Merge branch 'perf/core' Conflicts: tools/perf/check-headers.sh diff --cc tools/perf/check-headers.sh index 499235a41162,93c46d38024e..1f73e6f7438c --- a/tools/perf/check-headers.sh +++ b/tools/perf/check-headers.sh @@@ -28,7 -28,7 +28,11 @@@ arch/x86/include/asm/disabled-features. arch/x86/include/asm/required-features.h arch/x86/include/asm/cpufeatures.h arch/x86/include/asm/inat_types.h ++<<<<<<< HEAD +arch/x86/include/asm/emulate_prefix.h ++======= + arch/x86/include/asm/msr-index.h ++>>>>>>> perf/core arch/x86/include/uapi/asm/prctl.h arch/x86/lib/x86-opcode-map.txt arch/x86/tools/gen-insn-attr-x86.awk ----->8---------->8---------->8----- That's still on next-20191024.
