Hi

Be informed that I tried to maintain VGA PassThrough for Xen 4.2.

Since a few day, I notice that VGA PassThrough for Nvidia crash for domU and dom0 for revision >= 24492.

To be more precised, HVM domU with VGA PassThrough patches crash for revision submitted by Wei Wang

"ATS device driver that support PASID [1] and PRI [2] capabilites needs
to work with iommu driver in guest OS. We have to expose iommu
functionality to HVM guest, if we want assign ATS device to it. A new
hypervisor mmio handler is added to intercept iommu mmio accesses from
guest."

Revision higher than 24492 will not succeed to

I tried a lot of solution but all revisions >= 24492 fail.

I am not a Xen Expert but let me know if I can help.

Regards.

David.
