Hi, I'm looking for the closest thing to an official spec for qemu's fw_cfg device, and so far I have found this:
http://lists.gnu.org/archive/html/qemu-devel/2011-04/msg00238.html but it apparently never got committed to qemu (any idea why not?). Googling around didn't get me much further than that. Is there anything better or more up to date floating around out there somewhere ? Thanks much, --Gabriel
