    Default Will Asrock have BIOS support for IOMMU on its 890FX Deluxe3 ??

    All three of Asus 890FX boards support IOMMU in their BIOS -
    see these two links:
    ASUSTeK Computer Inc.-Forum- IOMMU support in BIOS (like for Crosshair IV) ?
    and
    ASUSTeK Computer Inc.-Forum- AMD-Vi (IOMMU)

    Now the world and his dog want to know what's Asrock's official stance on implementing IOMMU support in an upcoming BIOS for the 890FX Deluxe3!

    If affirmative answer when approximately can we expect a beta BIOs to try out?

    Please also take a look at this thread:

    I contacted Asrock support several times.

    First answer was: They don't support it because the chipset not supports IOMMU

    Second anser was: OK, the chipset supports it, but the AM3 cpus are not supporting IOMMU

    Third answer was: OK, Asus can do this we give it to our bios team

    now: waiting for answer. I will post it as soon as I get it.

    OK, can you give us the date for their last (3rd) reply ?

    That's funny, hopefully Gigabyte will follow suite as well :)

    Bad news. Today I got an answer from asrock support:

    Sorry for lat reply. Taiwan was still checking this issue. And they told us:
    Again IOMMU also need CPU to support.
    Till now, AMD has no plan to support IOMMU on desktop CPU (AM3 socket).
    Also "IOMMU" not list on our 890FX Deluxe3 specification
    Please 890FX Deluxe3 link:
    ASRock > Products > 890FX Deluxe3
    In feature, AMD release that CPU, we will borrow it, and test it.
    Any news will update to you.
    Thanks your mail.
    Best regards,

    ASRock Support
    So they don't believe me that it is not a cpu feature, even an AMD man postet to the xen-devel-list:
    IOMMU doesn't require CPU support. It is a feature of chipset. I think Biostart means SVM feature of CPU, which is supported by Phenom II.
    I think we can bury asrock boards with 890fx :-(

    Well, it's very unfortunate for us having to communicate with an offical tech support representative whose mastery of the English language and computer technology intricacies is at this surprisingly deplorable state. But I'm willing to have a go at it myself so tomorrow I'll be posting them an IOMMU ticket at http://www.asrock.com/support/tsd.asp.

    I'll be back!

    Hi!

    Again information about Asrock 890FX Deluxe3.
    I got a custom made bios from asrock support today. I've tested it and after flashing there is a iommu option in the bios. After activation the pci passthrough works with xen.

    lspci on hvm guest:

    hvm-01:~# lspci
    00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02)
    00:01.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II]
    00:01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II]
    00:01.2 USB Controller: Intel Corporation 82371SB PIIX3 USB [Natoma/Triton II] (rev 01)
    00:01.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 01)
    00:02.0 VGA compatible controller: Technical Corp. Device 1111
    00:03.0 Class ff80: XenSource, Inc. Xen Platform Device (rev 01)
    00:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 20)
    00:05.0 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)
    the last device (Intel HDAudio) was passed to the guest and works in virtual machine.

    I send this bios to the xen-devel list and asked for a download link (and adding this board to the wiki list) at VTdHowTo - Xen Wiki. If someone wants this bios, send me a private message and I will mail it.

    Jens

    Great stuff indeed!

    BTW there's a chipset cooling fan on the Asrock - how loud is it ? Could it be annoying (high-pitched) if otherwise silent CPU & PSU fans together with a fanless graphics card ?? (Maybe it's possible to switch it off for a non-overclocked PC ?!?)
