GDB step debugging does not have debugging symbols on kernel 6.8 #318
Description
Just tried the most basic:
cd submodules/linux
git checkout v6.8.12
cd -
./run --gdb-wait --linux-build-id v6.8
and:
./run-gdb start_kernel --linux-build-id v6.8
The breakpoint was hit:
root@lkmc:~/lkmc# ./run-gdb --linux-build-id v6.8 start_kernel
+ cd /root/lkmc/out.docker/linux/v6.8/x86_64 && \
/root/lkmc/out.docker/buildroot/build/default/x86_64/host/usr/bin/x86_64-buildroot-linux-gnu-gdb \
-ex 'add-auto-load-safe-path /root/lkmc/out.docker/linux/v6.8/x86_64' \
-ex 'file /root/lkmc/out.docker/linux/v6.8/x86_64/vmlinux' \
-ex 'target remote localhost:45457' \
-ex 'break start_kernel' \
-ex continue \
-ex 'lx-symbols /root/lkmc/out.docker/kernel_modules/x86_64/kernel_modules' \
