| |
Currently CONFIG_DEBUG_INFO_BTF=y doesn't work on UML:
scripts/link-vmlinux.sh: line 106: 17463 Segmentation fault LLVM_OBJCOPY=${OBJCOPY} ${PAHOLE} -J ${1} objcopy: --change-section-vma .BTF=0x0000000000000000 never used objcopy: --change-section-lma .BTF=0x0000000000000000 never used objcopy: error: the input file '.btf.vmlinux.bin' is empty Failed to generate BTF for vmlinux Try to disable CONFIG_DEBUG_INFO_BTF make: *** [Makefile:1078: vmlinux] Error 1
So turn off ARCH_HAS_BTF_TYPEINFO support off for the UM architecture.
