Hello,

I am new to the QEMU code base and I am working on a project involving a
custom hardware model representing a customized ppc board.  What is the
best way to add command line arguments applicable to my model?

I see options in qemu-options.hx + vl.c, but I am not sure if that is the
right place for arguments that only apply to one model, and I am not sure
how to access those options from my model.

I also see the function qemu_opts_create which looks like it can add
command line arguments at runtime, but I am not sure where to use this in
my model since it seems like my model code (machine state, class, and
instance functions) does not run when invoking "qemu-system-ppc -machine
mymodel -help".

If there is some good documentation or examples, please point me in the
right direction.

thanks for your help,
Mark
