Xen 4.2 VGA PassThrough Nvidia crash for revision 24492:6c104b46ef89 and higher
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.
