Hi developers,
i'm currently trying to test pci passthru on a ht2000/ht1000 platform (Tyan
h2000M (S3992-E) ).
Using enable_amd_iommu with Xen 3.2.0 shows "AMD IOMMU not present".
Could reworking this patch into 3.2.0 could solve this issue?
Or has this patch made it into xen-unstable, or is superseded by some later
work?
Thanks for any response!
Maybe IOMMU isn't supported on this mainborad, but I'm unable to get a clear
answer from tyan.

Hi,
The following 4 patches enable direct device assignment (PCI passthru)
for HVM guest
on AMD IOMMU platforms. Please apply them against C/S 16491 as the named
order.
To enable AMD IOMMU, please add "enable_amd_iommu" as xen boot
parameter.
1-cleanup.patch: code cleanup, bug fix, minor enhancements to existing
amd-iommu codes.
2-passthru-amd.patch: passthru support, modifications to exsiting
amd-iommu codes.
3-passthru-xen.patch: passthru support, minimodifications to in xen and
