    Hi, I had trouble trying to get this information so I thought I would put this here incase someone else would like to know

    Supermicro Super Server/X11SPH-nCTF, BIOS 2.0b 02/26/2018

    This was after adding "iommu=1 intel_iommu=on" to grub

    ******
    EDIT:
    At this point my post goes south please go to post #6 for the IOMMU group list.

    Here is another little tidbit of interest, the DMAR section of the dmesg log. Note the X2APIC bit.

    Once my testing of a newly added batch of HDD's has completed, I'll update my grub and have another look. There is a lot of banter around the net and linux kernel mailing lists regarding x2apic, BIOS and the people that program them.

    I don't know how I feel that there is no DMAR notice on startup abut IOMMU bing enabled. But from what I've gathered , this is jus t reporting that I have "intel_iommu=on" on my grub.cfg, so it is really no indication that iommu is actually enabled. However, I do have it in my grub config and it's not being reported, so there is that for confusion.

    One of my uses cases fro this motherboard is as a napp-t or ESXi AIO server with the onboard SAS3 adaptor and sata ports (the 2 SFF-8087 ports) and the 2 sSATA ports (the two powered data ports) going to mirrored drives for ESXi host.

    Unfortunately, it would appear due to the IOMMU grouping that I can only pass the on board LSI3008 SAS3 to the napp-it guest, maybe to sSATA controller as well as I think the two unregistered items in the same group are power controllers for DOM support.

    Your first post is wrong. It looks like a lspci, there is no grouping information at all. Either wrong copy paste, or wrong script.

    intel_iommu=on is enough to get running the part of the Linux Kernel that builds the IOMMU Group info and to do PCI Passthrough with QEMU-KVM-VFIO. I'm not sure if iommu is still used or is legacy since I see iommu=pt often, but didn't looked into it to see what it actually does (Supposedly it "sets the IOMMU for Passthrough mode", but I don't have it and do Passthrough anyways with just intel_iommu=on, so...).
    VMWare ESXi is a Type 1 Hypervisor that should need to implement its own low level interfaces, so your findings about what the Linux Kernel sees may not be representative of what ESXi sees. Same with Xen, which had no concept of IOMMU Groups at all back when I used it for PCI Passthrough before migrating to QEMU.

    The x2APIC thing has a long history behind it. I wrote about it here. Basically, some Firmwares have a Bit set that tells an OS that checks for it to not enable x2APIC. It was a workaround added since when x2APIC debuted in the Nehalem era, it was bugged, but it was fixed YEARS AGO and there should be no reason why any modern Firmware has it enabled by default. You can either see if you can disable the X2APIC Opt Out Bit in the Firmware, or force the Linux Kernel to use x2APIC anyways with a Kernel Parameter.
    You need x2APIC enabled to use APICv (APIC Virtualization) on Intel Ivy Bridge-E+ platforms (Not supported on the consumer platforms. Your Skylake-E should support it).

    Zir…blazer. You are correct, my first post is wrong. Oh so wrong it’s embarrassing. It would appear that I’m struggling to get IOMMU switched on with this motherboard and the FAQs on the Supermicro site don’t line up with this boards bios, I might send them an email.

    I didn’t know that about ESXi, cheers

    iommu=pt from my understanding helps a lot with sr-iov performance, according to the Mellanox material I’ve read. I intend to use VF with the nics.

    OK, found the the BIOS settings to get VT-D and IOMMU and all the magic for passthrough working with this motherboard. Helps when you down download and read the manual (the good old RTFM usually never fails)

    BIO settings from page 86 of the manual

    Intel® VT for Directed I/O (VT-d)Intel® VT for Directed I/O (VT-d)

    Select Enable to use Intel Virtualization Technology for Direct I/O VT-d support by reporting the I/O device assignments to the VMM (Virtual Machine Monitor) through the DMAR ACPI tables. This feature offers fully-protected I/O resource sharing across Intel platforms, providing greater reliability, security and availability in networking and data-sharing. The options are Disable and Enable.

    Interrupt Remapping
    Use this feature to enable Interrupt Remapping support, which detects and controls external interrupt requests. The options are Enable and Disable.

    PassThrough DMA
    Use this feature to allow devices such as network cards to access the system memory without using a processor. Select Enable to use the Non-Isoch VT_D Engine Pass Through Direct Memory Access (DMA) support. The options are Enable and Disable.

    ATS
    Use this feature to enable Non-Isoch VT-d Engine Address Translation Services (ATS) support. ATS translates virtual addresses to physical addresses. The options are En- able and Disable.

    Posted Interrupt
    Use this feature to enable VT_D Posted Interrupt. The options are Enable and Disable.

    Coherency Support (Non-Isoch)

    What about x2APIC and APICv? Did you got them working?

    When I had ubuntu installed on it I had to add an entry to my grub, I can't remember what exactly but the error tells you what you to add)
    I have proxmox 5.2 installed now.

    Here is the dmesg output

    Code:
    [    0.000000] x2apic: enabled by BIOS, switching to x2apic ops

[    0.000000] Setting APIC routing to cluster x2apic.

[    0.000000] ACPI: X2APIC_NMI (uid[0xffffffff] high level lint[0x1])

    The x2apic: enabled by BIOS seems better than your previous
    DMAR-IR: x2apic is disabled because BIOS sets x2apic opt out bit. Did you found the X2APIC Opt Out Bit I said early? Since it seems that now the Firmware isn't telling the Linux Kernel to not use x2APIC, that is why it seems that you don't need to override. So it seems that it works now out of the box.

    Does...
    cat /sys/module/kvm_intel/parameters/enable_apicv
    ...gives a Y or N?

    When I get a bit of time I'll do a DIY server build post.

    I've dropped ESXi as I could only get ver.6.7 as an evaluation and all the tricks to get sata passthrough for the Lewisburg controller no longer work. I've passed both the SATA (not the sSATA) and the LSI controllers through to a FreeNAS guest and have some test shares working. I'm working on GPU passthrough to a win10 guest ATM (for steam streaming as some games aren't available for linux)
