Re: [Qemu-devel] [PATCH] Port E9 hack, for debugging purposes

[Fabrice Bellard]

There are already similar debug features in hw/pc.c for the Bochs BIOS, 
but they are not enabled by default because I consider there were useful 
only in rare cases.

I would accept the "e9 hack" only if it was dynamically configurable and 
if it used a generic character device (as the serial or parallel ports) 
to output its results. The command line option should be '-port-e9 
stdio' or something similar.
