** Description changed: [ Impact ] During the keynote presentation at Microsoft Ignite, 2024, Microsoft announced the private preview of a new series of AI-oriented Azure virtual machines based on the NVIDIA GB200 superchip: https://techcommunity.microsoft.com/blog/azurehighperformancecomputingblog/microsoft- adopts-nvidia-blackwell-to-power-the-next-frontier-of-ai- supercomputin/4303541 . As part of Microsoft’s and Canonical’s joint effort to ensure that the latest Ubuntu LTS release supports the most salient features of this new virtual machine series, Canonical would like to back-port all post-24.04 changes to the Microsoft Azure Network Adapter (MANA) provider in rdma-core from ubuntu/devel to ubuntu/noble.

[ Other Info ] The second point under https://documentation.ubuntu.com/sru/en/latest/reference/requirements/#other- safe-cases describes the changes that Canonical is seeking to back-port to ubuntu/noble. As such, the changes, while representing new features, appear to qualify for SRU. The patches associated with the SRU request only touch the following files, all of which are MANA-specific: providers/mana/* kernel-headers/rdma/mana-abi.h Furthermore, the patches encapsulate all the changes to those files since the Ubuntu 24.04 release; there are no residual changes to those files that the patches do not cover.
