Yup, I've documented the steps to use it at
https://code.bluestop.org/w/tianocore/debugging-with-gdb/ .

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.
