To work with modern versions of gdb which use Python 3, you can just run 2to3 (https://docs.python.org/3.7/library/2to3.html) on gdb_uefi.py which I checked last night works. I tried using it with a Bhyve build of OVMF (https://github.com/freebsd/uefi-edk2/tree/bhyve/edk2-stable201903) but it didn't work and I didn't have time to look into why. It might just be because Bhyve's gdb server is fairly basic at the moment. -- Rebecca Cran
