[SOLVED] BTF compilation error on zen-kernel-6.11.5-zen1

Hello,

I'm trying to patch and compile latest zen-kernel using the ABS guide here: https://wiki.archlinux.org/title/Kernel … ild_system

I've modified the PKGBUILD file to match version, apply patch and add "zero-rpm-patch" tag.
Issue trying to patch: https://gitlab.freedesktop.org/drm/amd/-/issues/3489 - actual patch: https://lists.freedesktop.org/archives/ … 15857.html

Error registered in terminal:

make: se entra en el directorio 'linux/src/zen-kernel-6.11.5-zen1/tools/bpf/bpftool'

  GEN     vmlinux.h
libbpf: failed to find '.BTF' ELF section in linux/src/zen-kernel-6.11.5-zen1/vmlinux
Error: failed to load BTF from linux/src/zen-kernel-6.11.5-zen1/vmlinux: No data available

make: se sale del directorio 'linux/src/zen-kernel-6.11.5-zen1/tools/bpf/bpftool'
==> ERROR: Se produjo un fallo en build().
    Cancelando...

Tried several configurations regarding BTF subsystem and debug options, same result so far.

Any kind of guidance or help it's really appreciated. Many thanks in advance.

Kind regards

Re: [SOLVED] BTF compilation error on zen-kernel-6.11.5-zen1

Could you be more specific on how you got that error i.e. which build command you used? Also which diff do you currently have applied to the upstream PKGBUILD?

Thanks for replying. Here's the diff between the original file and the modified one I'm using:

The base file is this one.

The line producing the error is

  make -C tools/bpf/bpftool vmlinux.h feature-clang-bpf-co-re=1

I've been searching on the web about this issue and it seems to be related to BPF subsystem options that needs other development options activated to work properly, but I still haven't found the right combination of options for this to work.

Re: [SOLVED] BTF compilation error on zen-kernel-6.11.5-zen1

If you remove the use of `make menuconfig` so you use Arch's config does that work?

@gromit if you have time could you please have a look at https://bbs.archlinux.org/viewtopic.php?id=299945

Thanks for replying. I added that line so I could try different settings on the config file, arch's config is accepted but compiling ends up in that error anyways.

Re: [SOLVED] BTF compilation error on zen-kernel-6.11.5-zen1

Do you do modifications on the config? Normally this error happens if you disable BTF or any other debug related things in the kernel config.

Do you do modifications on the config? Normally this error happens if you disable BTF or any other debug related things in the kernel config.

Thank you very much for replying. I finally managed to compile the kernel this morning. Turns out I had some options active by default in my kernel config:

#
# Compile-time checks and compiler options
#
CONFIG_DEBUG_INFO=y
CONFIG_AS_HAS_NON_CONST_ULEB128=y
# CONFIG_DEBUG_INFO_NONE is not set
# CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT is not set

CONFIG_PAHOLE_HAS_SPLIT_BTF=y

# CONFIG_DEBUG_INFO_BTF_MODULES is not set
# CONFIG_MODULE_ALLOW_BTF_MISMATCH is not set
CONFIG_GDB_SCRIPTS=y
CONFIG_FRAME_WARN=2048
CONFIG_STRIP_ASM_SYMS=y
# CONFIG_READABLE_ASM is not set
# CONFIG_HEADERS_INSTALL is not set
# CONFIG_DEBUG_SECTION_MISMATCH is not set
CONFIG_SECTION_MISMATCH_WARN_ONLY=y
CONFIG_OBJTOOL=y
# CONFIG_DEBUG_FORCE_WEAK_PER_CPU is not set
# end of Compile-time checks and compiler options

This option set resulted in successful compilation:

#
# Compile-time checks and compiler options
#
CONFIG_DEBUG_INFO=y
CONFIG_AS_HAS_NON_CONST_ULEB128=y
# CONFIG_DEBUG_INFO_NONE is not set

# CONFIG_DEBUG_INFO_SPLIT is not set
CONFIG_DEBUG_INFO_BTF=y
CONFIG_PAHOLE_HAS_SPLIT_BTF=y
CONFIG_PAHOLE_HAS_LANG_EXCLUDE=y
CONFIG_DEBUG_INFO_BTF_MODULES=y

CONFIG_STRIP_ASM_SYMS=y
# CONFIG_READABLE_ASM is not set

CONFIG_SECTION_MISMATCH_WARN_ONLY=y
CONFIG_OBJTOOL=y
# CONFIG_DEBUG_FORCE_WEAK_PER_CPU is not set
# end of Compile-time checks and compiler options

Still don't know how or when that section was changed since I copied the config from the precompiled zen kernel I was running, and used it as base to tune very few options like architecture specifics or scheduler options. Anyway, while researching I found more people having this issue in other forums, so I hope this helps.

Thank you all very much for your quick and helpful responses. Adding solved tag to the title.
