[Bug 1712031] Re: PXE boot with Intel Omni-Path feature request

[Tymoteusz Kielan]

1. Feature Overview:
    a) Name of feature:
        Add Intel Omni-Path Architecture (OPA) Firmware to initrd.gz

    b) Feature Description:
        The initrd.gz supplied on Ubuntu 17.04 is missing 
        the following firmware listed below in the /lib/firmware directory.  
        As a result, PXE boot over fabric fails.

        hfi1_dc8051.fw
        hfi1_fabric.fw
        hfi1_pcie.fw
        hfi1_sbus.fw
        hfi1_smbus.fw (to be confirmed)

        These firmware binaries can be found in the standard Ubuntu distro or 
        linux-firmware (except hfi1_smbus.fw)

2. Feature Details:
    a) Architectures:
        64-bit Intel EM64T/AMD64

    b) Drivers or hardware dependencies:
        Omni-Path HFI, HFI driver

    c) Upstream acceptance information:
        Part of linux-firmware

    d) Severity (H,M,L):
        High

    e) Feature Needed by:
        Ubuntu 18.04 LTS

3. Business Justification: 
    a) Why is this feature needed?
        The firmware is required for the HFI card for Omni-Path Architecture.

    b) What hardware does this enable?
        Omni-Path HFI

    c) Is this hardware on-board in a system (eg, LOM) or an add-on card?
        PCIe card

    d) Business impact?
        Required for Omni-Path

Title:
  PXE boot with Intel Omni-Path feature request

Status in debian-installer package in Ubuntu:
  New

Bug description:
  This is about ability to PXE boot over Intel Fabric.
  Netboot initrd is missing infiniband kernel module stack along with hfi1.ko (for 1st generation of Intel Omni-Path cards).
  In addition some firmware files required to load modules are also missing in initrd.
  This firmware came from existing linux-firmware package, but is not included in netboot initrd image.
  I wanted to request such feature for upcoming LTS release.
