I am currently working pretty hard to make this possible in the future, it
would be a shame to add another reason it wasn't possible at this stage.
I proposed (in <1445442435.9563.184.camel@citrix.com>) that as well as the
various stable libraries extracted from libxenctrl we will probably also
want to have a libxendevicemodel.so at some point, to provide a stable way
to interface with all the stuff which being a DM involves.
Maybe that library could contain a way to get this information? (In which
case it could be hardcoded at compile time now and I'll see what I can do
when I get to producing the library).
For the original issue here, could the flag be exposed as a
XEN_SYSCTL_PHYSCAP_????
Ian.
