Tony Ambardar 531e0399cd build: add option KERNEL_DEBUG_INFO_BTF ... Generate BTF (BPF Type Format) information from DWARF debug info. This is embedded in the kernel and exported via sysfs as /sys/kernel/btf/vmlinux. BTF data enhances kernel portability and introspection for BPF programs. Selecting this also enables the dwarves host package which provides the pahole tool used for BTF encoding. Test using: "bpftool btf dump file /sys/kernel/btf/vmlinux format c" This needs to depend on KERNEL_DEBUG_INFO_REDUCED not being set, otherwise we can enable both KERNEL_DEBUG_INFO_BTF and KERNEL_DEBUG_INFO_REDUCED, which will result in undefined behaviour.
