If it helps your investigation we have a little bit of what you are looking for implemented in our fork. You can see the XML that we expose here: https://github.com/Xilinx/qemu/blob/master/gdb-xml/aarch64-el3.xml Our GDB stub is pretty divergent though, we are working on trying to improve it, but it's slow going.
