[Xen-devel] [PATCH] small fixes for the FLR logic in xend

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

[PATCH1] relax_the_coassignment_requirement.patch:
Certain PCI or PCIe devices needs to be co-assigned. Currently we
require all
the related devices be assigned to the same guest. This can be relaxed
to:
part of them can be assgined to the same guest, and after that, the left
ones
can't be assigned.

[PATCH2] use_dstate.patch:
Currently integrated devices without proper FLR capability are not
assignable.
This is not nice since actually they may be assignable, but due to old
BIOS
the proper FLR capability is not exposed.
We can use the previously-used Dstate transition method to do FLR for
them.
This works well and looks few issues are reported AFAIK. Maybe we can
make
a black list for the (rare) integrated devices that don't work with this
method.

Thanks,
