    I have a cheap Asrock 890FX Deluxe3 to sell, if someone interests :-(

    Oh cool, very cool. I'm fine for waiting if I know they are working on it.

    Thanks Lsdmeasap for the good news!

    Yeah... their excuse doesn't make any sense to all the online research we have done regarding IOMMU. I think you should get yourself a Gigabyte board and jump ship with Asrock, as their excuse is very poor (unless I'm not understanding something)... :P

    Cheers!

    Asrock parent company is ASUS.
    I don't think their technical support knows what IOMMU is.

    ASUS stated that M4A89TD has IOMMU. I don't trust them until I see a "xm dmesg".

    Dell customer services told me that all their Core iX computers support VT-d.
    I don't think that correct. That is why I don't really trust tech support.

    I got pci passthrough working with Asus Crosshair IV and xen hg testing tree.

    With xen-4.0-testing.hg tree + 2.6.32-bpo.5-xen-amd64 (from debian lenny backports) it works. So the 4.0.0 release could be buggy?
    When I compile and install xen-4.0-testing.hg tree it works. With 4.0.0 relase I got always errors.
    With 4.0.0 it did not work with any pci device, with xen-4.0-testing.hg tree it works with the two I tested for the moment:

    00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)
    03:00.0 Ethernet controller: Marvell Technology Group Ltd. Device 4381 (rev 11)

    (I just randomly take two devices).
    They appear in the hvm virtual machine and they are working.

    I can tell you on monday.

    Hey, first of thanks for your diligence kuzew in keeping this thread alive and everyone else for their input, I have just subscribed to this forum after reading this thread, I was spending a long time searching for a thread which contains people who know what their looking for! I have spent ages trying to discover which motherboards contain the mysterious IOMMU/VT-d. Trying to get this information, accurate information anyway is painstaking.

    Its so irritating to find out if IOMMU/VT-d is present on desktop boards.

    Back on topic, I too am trying to find a cheap testing platform for PCI passthrough to HVM guests. A college of mine recently purchased the following motherboard as a cheap hypervisor platform: "Asus M4A785TD-V EVO" He claimed that VMware recommended it somewhere in support of "DirectPath", which I believe is a ESX name for binding a particular PCI device to a singular virtual machine( guest domain ), however Im not that familiar with ESX so please excuse me if that was incorrect. I will ask him to run "lspci -vv" and "dmesg" along with "xm dmesg".

    Its quite annoying that vendors have no interest in promoting such a cool feature. I have access to hardware such as Dell R710, R900, R815, 2950 and a couple of different supermirco boards, I can get "dmesg" and "lspci" output from these machines as well if you need confirmation on what should be present, however I cannot take these machines home with me :(

    I got a reply back from Gigabyte technical support, the same exact word answer from the last time I asked!
    Dear Customer

    Unfortunately this feature is not supported on this board
    Actually, if you go back to when I posted the response the first time I asked, it is the same exact ... everything. No periods or any punctuation. I'm not impressed. Technical support guys don't do any research to see if the motherboard/BIOS guys are fixing/patching things up? I was expecting a answer like, they are working on it. Well, only a few more weeks till we have IOMMU present in the BIOS for Gigabyte boards! Can't wait!

    As for majorbushbar, I'd have to look up if Intel's VT-d represents itself to the OS differently from AMD's IOMMU/AMD-Vi, meaning if the PCI address is different from what the AMD boards gives to the OS. I assume the Dell boards are Intel boards. The Asus M4A785TD-V EVO board has a AMD 785G northbridge chipset and therefore doesn't have IOMMU/AMD-Vi on chip. You must look at ONLY the 890FX chipset (note, FX and not GX), the trick is to find the BIOS with the correct implementation, reason why this thread was started.

    I trust you have looked at this: VMware Communities: VMware VMDirectPath I/O ?
    They sight that the board must have for AMD, IOMMU and for Intel, VT-d for what they call DirectPath. It's interesting whoever recommended you at board that doesn't have any IOMMU support... even rumoured. Take a look at this as well: Old Nabble - Xen - User - I/O virtualisation on AMD 785G chipset

    Also, `xm dmesg` will won't be of help if you are not running the Xen hypervisor. Just try simply `dmesg` for non-Xen, GNU/Linux setups.

    Thanks for joining all of us to try to hunt down what boards really support IOMMU. Cheers!

    I just spoke to him and it turned out he was unaware of IOMMU/VT-d. I delivered him some bad news today.

    I wondered if going through the BIOS data with a utility called hexdump would show anything useful, however searching for strings is not a proven concept, the BIOS data could contain strings like IVRS/iommu/vt-d but make no use of it :(.

    Yes the Dell machines (R900,R710,2950) all use Intel Xeon families, however the R815 is a opteron 6100 based system, so that might be worth a 'dmesg'.

    @kuzew
    The Gigabyte 890FX BIOS is made by Award.
    Could be that Award doesn't want to assign the man-hours to add IOMMU support even if Gigabyte in fact has asked them for assistance. I think that of all the 890FX board manufacturers only Gigabyte uses Award and all the rest AMI. And MSI btw is abandoning legacy BIOS (AMI) altogether soon for UEFI - at least for its upmarket m/b's.
    So maybe it's really better for you to sell off your GB m/b and buy an Asus or MSI one ?
