Public bug reported: Hi,
It would be great if Raspberry Pi kernels could enable BTF. It's not enabled at the moment: $ ls /sys/kernel/btf/vmlinux ls: cannot access '/sys/kernel/btf/vmlinux': No such file or directory I think the minimal change is to add CONFIG_DEBUG_INFO_BTF=y and the default kernel has it enabled: https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/focal/tree/debian.master/config/config.common.ubuntu?h=Ubuntu-5.4.0-92.103#n2322 Thanks!
