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.
