[linux-image-5.10.0-1-amd64] Requirement of pahole binary with CONFIG_DEBUG_INFO_BTF=y

[Sedat Dilek <sedat.dilek@gmail.com>]

Hi,

yesterday, I installed linux-image-5.10.0-1-amd64 version 5.10.5-1
from Debian/unstable.

I am building custom Linux-kernels mostly to test with LLVM/Clang and
use Debian's kernel-config file as a base for my work.

With CONFIG_DEBUG_INFO_BTF=y there is a requirement for pahole binary
from dwarves package.

The requirement is coded in [1]:

if ! [ -x "$(command -v ${PAHOLE})" ]; then
echo >&2 "BTF: ${1}: pahole (${PAHOLE}) is not available"
return 1
fi

Is there an install-recommendation for dwarves package?
If not - I would like to open a bug-report.

If you need further information, please let me know.

Thanks.

Regards,
