similar to: Xen 4.2.1 boot failure with IOMMU enabled

Hi all I already posted about this problem on xen-users some time ago (http://markmail.org/message/sbgtyjqh6bzmqx4s) but I couldn''t resolve my problem using help from people on xen-users, so I''m posting here . I have a problem with enabling IOMMU on Xen 4.2.1. When I enable it in BIOS and in grub.conf using iommu=1 kernel option, my machine cannot boot. I get a following error

Hello, After saving and restoring a DomU (teste on the same server), doing a reboot to the newly restored domU will cause it to crash. This happens on PV and PVHVM domUs. I am using qemu upstream for the HVM guests, but I don''t really think it matters as long as PV guests behave the same. I want to confirm this if possible, before submitting a bug report and more details. I am using

The iommu is enabled by default when xen is booting and later disabled in iommu_setup() when no iommu is present. But under some circumstances iommu code can be called before iommu_setup() is processed. If there is no iommu available xen crashes. This can happen for example when panic(...) is called as introduced with the patch "x86-64: detect processors subject to AMD erratum #121 and

Hi, All the reviews for the AMD 890fx chipset reported that it supports IOMMU v1.2. But I cannot find any mention of that on AMD site. Does 890fx support IOMMU? Do 890fx motherboards with IOMMU exist? Does Xen support 890fx?

This patch set adds basic supports for amd next generation iommu (IOMMUv2) hardware. IOMMUv2 supports various new features advertised by iommu extended feature register. It introduces guest level IO translation and supports state-of-the-art ATS/ATC devices with demand paging capability. Please refer to AMD IOMMU Architectural Specification [1] for more details. Thanks, Wei [1]

Greetings Xen user community, I am interested in using Mellanox ConnectX cards with SR-IOV capabilities to passthrough pci-e Virtual Functions (VFs) to Xen guests. The hope is to allow for the use of InfiniBand directly within virtual machines and thereby enable a plethora of high performance computing applications that already leverage InfiniBand interconnects. However, I have run into some
