Title:
[NEEDS PACKAGING] doca-ofed-25.10-dkms DKMS suite

Status in linux package in Ubuntu:
In Progress

Bug description:
Support for doca-ofed-25.10 DKMS in Ubuntu Noble


[ SRU Justification ]

This is an effort to repackage the DKMS portion of the doca-ofed upstream package distributed by NVIDIA through a public HTTP source (e.g. https://linux.mellanox.com/public/repo/doca/).
NVIDIA distributes this as a set of deb packages in a tarball at the following address: https://developer.nvidia.com/doca-downloads; this package is for the 3.2.1 version of the upstream NVIDIA package.


Current Ubuntu packaging lacks support for NVIDIA Bluefield/IGX platform: this is needed as customers using NVIDIA hardware can take advantage of custom, high performance drivers directly through Canonical apt system, without the need of downloading an external tarball to be manually installed on the target machines.

This helps as well any automated installation flow as, by just
specifying the need for this package as an apt dependency, avoids the
automation issue of finding the HTTP address of the latest version of
the doca-ofed package distributed by NVIDIA and the relative scripting
to manually install them.

This package adds a set of kernel modules related to the NVIDIA mlnx5
hardware family.

This package is related to the https://launchpad.net/ubuntu/+source/mofed-modules-24.10/ package already accepted last year. This is the newer LTS version distributed by NVIDIA.
There are no modification in repackaging, apart from a more coherent name with NVIDIA naming scheme, has been applied to the repackaging.
Another difference from the 24.10 version, is a smaller list of .ko files that will be built on the target machine, following what invoking the doca-ofed target on the original package installs.


[ Current Test Plan ]

* Tested on
* Noble-nvidia-tegra derivative kernel 6.8.0-1013.13 / 6.8.0-1014.14
* Noble 6.8.0-71-generic, 6.8.0-88-generic and 6.8.0-90-generic
* Questing 6.17.0-7-generic and 6.17.0-8-generic

* Before upstreaming an update version of the repackaged kernel
modules, a local test to the affected kernels must be executed. At the
moment, the main target kernel is the noble:linux-nvidia-tegra one, so
the tests will be thoroughly executed on the specific hardware running
said kernel. If the modules load correctly, the package is considered
sane and can be uploaded to the wider public.


[ Where problems could occur ]

* No issues can be thought, as this is an extra package to be
manually installed by a customer and, without the necessary hardware,
no driver is automatically loaded in memory.


[ Other Info ]

* The repackaging code is contained in the repository at the
following address:
https://kernel.ubuntu.com/forgejo/alessiofaina/nvidia-doca-ofed-dkms

* Examples of the repackaged DKMS can be found at the following
private PPA:
https://launchpad.net/~alessiofaina/+archive/ubuntu/mofed-autoupload-
test/+packages

* All the modules as GPL-2 or Dual BSD/GPL licensed, no closed source
binaries are redistributed.
