Xen VGA PassThrough NVIDIA: include pci-stub case for changeset 25240
Hi,
For concerned persons like me that compil Xen with PassThrough NVIDIA,
modifications introduced for changeset 25240 are limited (for the moment) for
pciback.
I am used to biding device using pci-stub (device : Video Card).
Commenting out modifications introduced for this changeset is not a good choice
(I approve!). This is the only fix I found - since I am not a Xen expert - to be
able to use NVIDIA patches for revision >= 25240
May it be possible to include case for devices with pci-stub usage?
