Hi,
Having updated my Xen to 4.0-rc9-pre recently, i decided to try
booting without the iommu=0 flag.
The system doesn't crash now (which is an improvement), but gracefully
disables VT-d due to an
unsupported IOMMU.
I've attached the output of xm dmesg, hope it is of use to someone.
Do let me know if there's something more i can do to help in getting
VT-d working on this board.
Regards,
Mark.

I think the BIOS is broken with respect to VT-d. Please try to update to the latest BIOS.
Thanks,

Subject: [Xen-devel] VT-d on Asus P7P55D-Evo: IOMMU not supported
Hi,
Having updated my Xen to 4.0-rc9-pre recently, i decided to try
booting without the iommu=0 flag.
The system doesn't crash now (which is an improvement), but gracefully
disables VT-d due to an
unsupported IOMMU.
I've attached the output of xm dmesg, hope it is of use to someone.
Do let me know if there's something more i can do to help in getting
VT-d working on this board.

Yeah, i figured as much. It's on the latest Asus Bios though (1307) which
was released only a few weeks ago. But since Xen is dumping VT-d related
register info, i thought i'd just post them here.
Asus doesn't seem to pay much attention to VT-d issues with their P55
boards, i couldn't find any indication that they are working on it.
I tried to submit a tech support question, but it requires a serial number,
which i seem to be unable to locate on the board.
Regards,
Mark.

Try "dmidecode" in dom0 or on baremetal linux, it might show you the serial..

Even if you find the serial and open the support case there will be no
meaningful answer just "Linux is not supported". Been there, done that....

This just got posted on LKML that might shed the light on why certain
motherboards have VT-d working i7 but not with i5 CPUs:
(https://lists.linux-foundation.org/pipermail/iommu/2010-April/002268.html):
"
When using iommu_domain_alloc with the Intel iommu, the domain address width
is always initialized to 48 bits (agaw 2). This domain->agaw value is then
used by pfn_to_dma_pte to (always) build a 4 level page table. However, not
all systems support iommu width of 48 or 4 level page tables. In particular,
the Core i5-660 and i5-670 support an address width of 36 bits (not 39!), an
agaw of only 1, and only 3 level page tables.
My patch delays the domain initialization until the first iommu_attach_device,
