[Xen-users] [VT-D]iommu.c:775: iommu_page_fault: iommu->reg = ffff828bfff57000

Hello,

I have been working sometime now on getting a HVM accepting a PCI card from
the host. As was said in the VT-D wiki I bought an ASUS P5E VM DO
motherboard (rel 0803) which has the VT-D option in the bios. I want to pass
a Hauppauge PVR 500 card to a virtual machine running LinuxMCE. After first
trying XEN 3.2.1 which did not enable the "VT-D virtualisation" bit in
xm
dmesg, i upgraded the system to run XEN 3.3 which ended up having errors
regarding "(XEN) [VT-D]iommu.c:775: iommu_page_fault: iommu->reg
ffff828bfff57000" in xm dmesg

This happens both with and without pciback.hide in grub commandline. If I
use "pci [xx.xx.xx] in my HVM conf and boot the HVM the host crashes and I
have to hard reset the system. It will happen both for a PCI network card as
well as the capture card.

Is it possible to overcome the iommu_page_fault error in 3.3.0?
If not and I have to go to xen-unstable can someone provide me with a link
how to build xen-unstable. I am keen to learn but only have about 2 yrs of
experience.

Many thankx

Han

Re: [Xen-users] [VT-D]iommu.c:775: iommu_page_fault: iommu->reg = ffff828bfff57000

I use vtd=1 instead of iommu=1 but I''m not sure what the difference
is.  Also, I''m running Xen 3.2.1 that I compiled myself under a CentOS
5.2 x86_64 system.  I''ve stayed away from 3.3 until I see more
stability with VT-d.

(XEN) Xen version 3.2.1 (root@kaonetworks.com) (gcc version 4.1.2
20071124 (Red Hat 4.1.2-42)) Fri Jul 18 04:47:33 PDT 2008

(XEN) Latest ChangeSet: unavailable

(XEN) Command line: vtd=1

(XEN) [VT-D]intel-iommu.c:769: iommu_page_fault: iommu-&gt;reg
ffff828bfff57000

(XEN) [VT-D]intel-iommu.c:752: iommu_page_fault:DMA Write: DEVICE 0:2.0
addr 14404000 REASON 5

I have a similar fault error in my xm dmesg also but it doesn''t affect
the ability of using VT-d on a DVB-S PCIe card I use in an HVM.  Other
than that, there''s not much else I can offer in help.

Hello,

I have been working sometime now on getting a HVM accepting a PCI card
from the host. As was said in the VT-D wiki I bought an ASUS P5E VM DO
motherboard (rel 0803) which has the VT-D option in the bios. I want to
pass a Hauppauge PVR 500 card to a virtual machine running LinuxMCE. After
first trying XEN 3.2.1 which did not enable the "VT-D virtualisation"
bit
in xm dmesg, i upgraded the system to run XEN 3.3 which ended up having
errors regarding "(XEN) [VT-D]iommu.c:775: iommu_page_fault:
iommu-&gt;reg ffff828bfff57000" in xm dmesg

This happens both with and without pciback.hide in grub commandline. If I
use "pci [xx.xx.xx] in my HVM conf and boot the HVM the host crashes and I
have to hard reset the system. It will happen both for a PCI network card
as well as the capture card.

Is it possible to overcome the iommu_page_fault error in 3.3.0?
If not and I have to go to xen-unstable can someone provide me with a link
how to build xen-unstable. I am keen to learn but only have about 2 yrs of
experience.

Many thankx

Han

Cheers Daniel,

Good to hear you''ve got it going. I am using PCI however. I am about to
tear
the whole build done and run 3.2.1. again to see if that resolves some
issues.
