> This patch supports basic gfx passthrough on QEMU:

> - register/unregister legacy VGA I/O ports and MMIOs for passthroughed gfx
Thanks for this. However:
* It breaks the build if passthrough is disabled (eg due to lack
of pciutils-dev).
* Reindenting all of the code in pc.c which initalises out the
various graphics cards is very merge-unfriendly. Is that change
needed at all, or could you just disable the various graphics cards
on the qemu command line ?
* Likewise, in vl.c.
Regards,
Ian.
