How much of this is handled in AMD's binary VSA module? I have been
looking through both the AMD and OpenVSA source and it looks as if the
lxvg module is supposed to handle VGA SMIs but I cannot find where this
is actually done.
Incidentally, I have noticed that the AMD VSA source available from
dev.laptop.org cannot be used to build an image with CS5536 support. Is
this an old version and, if so, is newer source available?
