[ Upstream commit8af055ae25] If CONFIG_DEBUG_INFO_REDUCED is enabled in the kernel configuration, we will typically not be able to load vmlinux-gdb.py and will fail with: Traceback (most recent call last): File "/home/fainelli/work/buildroot/output/arm64/build/linux-custom/vmlinux-gdb.py", line 25, in <module> import linux.utils File "/home/fainelli/work/buildroot/output/arm64/build/linux-custom/scripts/gdb/linux/utils.py", line 131, in <module> atomic_long_counter_offset = atomic_long_type.get_type()['counter'].bitpos KeyError: 'counter' Rather be left wondering what is happening only to find out that reduced debug information is the cause, raise an eror. This was not typically a problem untile3c8d33e0d("scripts/gdb: fix 'lx-dmesg' on 32 bits arch") but it has since then.
