Hi Jani,
Is below video similar to what you want? This video shows cross-debug
armv8 linux kernel (using armv8-gdb + armv8-qemu).

Hi,
I would like to debug a Qemu guest linux kernel under Foundationv8 model and
I tried the following setup:
1. Foundationv8 model started with --network=nat and
--network-nat-ports=1234=1234 options
2. In Foundationv8 model I started qemu-system-aarch64 with the command
line:
./qemu-system-aarch64 -M virt -cpu host -kernel Image -serial stdio
-display none -enable-kvm -gdb tcp::1234 -S
3. I start debugging the guest kernel with aarch64-linux-gnu-gdb vmlinux
and with target remote:1234 command.
However when I set any breakpoint I will get error message:
"Cannot insert breakpoint 1.
Error accessing memory address 0xffffffc000636498: Unknown error -1"
In addition stepi or any other run related command does not work.
You would need to implement breakpoint support for AArch64 in
both KVM and QEMU, I think. That feature is currently not implemented.
thanks
