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 Or has this patch made it into xen-unstable, or is superseded by some later work?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. lspci -v shows following devices: 00:01.0 PCI bridge: Broadcom BCM5785 [HT1000] PCI/PCI-X Bridge (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 64 Bus: primary=00, secondary=01, subordinate=03, sec-latency=64 I/O behind bridge: 00009000-0000afff Memory behind bridge: f8700000-f88fffff Prefetchable memory behind bridge: 00000000af500000-00000000afcfffff Capabilities: [90] PCI-X bridge device Capabilities: [a0] HyperTransport: MSI Mapping Capabilities: [b0] HyperTransport: Slave or Primary Interface Capabilities: [d8] Subsystem: Gammagraphx, Inc.
