I found the problem: [ 2299.766819] Out of memory: Killed process 43216 (pahole) total-vm:8235296kB, anon-rss:4667816kB, file-rss:0kB, shmem-rss:0kB, UID:0 pgtables:12912kB oom_score_adj:0

pahole is current. The build fails inside the docker-shell when manually invoked as well. Looks like the BTF invocation is getting killed (maybe needs more RAM)? 🐳|🔨] BTF .tmp_vmlinux1.btf.o [🐳|🔨] Killed root@c408bbb4ccde:/armbian# apt show pahole Package: pahole Version: 1.25-0ubuntu3 Priority: optional Section: universe/utils Source: dwarves Origin: Ubuntu Maintainer: Ubuntu Developers <ubuntu-devel-discuss@lists.ubuntu.com> Original-Maintainer: Thomas Girard <thomas.g.girard@free.fr> Bugs: https://bugs.launchpad.net/ubuntu/+filebug Installed-Size: 2012 kB Depends: libbpf1 (>= 1:1.0.0), libc6 (>= 2.38), libdw1t64 (>= 0.157), libelf1t64 (>= 0.142), zlib1g (>= 1:1.1.4) Breaks: dwarves (<< 1.22) Replaces: dwarves (<< 1.22) Homepage: https://git.kernel.org/pub/scm/devel/pahole/pahole.git Download-Size: 275 kB APT-Manual-Installed: no APT-Sources: http://ports.ubuntu.com/ubuntu-ports noble/universe arm64 Packages Description: set of advanced DWARF utilities

@sven-ola I have docker. The build BRANCH=current works but BRANCH=edge errors in the BTF section.

@sven-ola I did try the BRANCH=edge build and got an ELF error: 🐳|🔨] libbpf: failed to find '.BTF' ELF section in vmlinux.unstripped [🐳|🔨] FAILED: load BTF from vmlinux.unstripped: No data available [🐳|🔨] make[2]: *** [scripts/Makefile.vmlinux:72: vmlinux.unstripped] Error 255 [🐳|🔨] make[2]: *** Deleting file 'vmlinux.unstripped' [🐳|🔨] make[1]: *** [/armbian/cache/sources/linux-kernel-worktree/6.18__spacemit__riscv64/Makefile:1242: vmlinux] Error 2 [🐳|🔨] make: *** [Makefile:248: __sub-make] Error 2

This is fantastic work! Thank you so much. I was able to build from source. Tested it on RV2 and R2S and both work great. Your changes are patched on to the 6.6.99 kernel as far as I can tell. Are these going to be merged upstream and make their way into 6.17? Thanks again for your amazing work.
