The near-term goal is enabling UALink over Ethernet (UALoE) for AMD's upcoming Helios servers, which pair Instinct MI455X accelerators with 6th Gen EPYC 'Venice' CPUs and Pensando AI NICs. The updated v2 patch series fixes 32-bit kernel build issues and drops the previously proposed sysfs-based configuration API in favor of out-of-band tooling, at least for now. The patches, spanning 95 changes plus a second updated series with documentation, missed the Linux v7.3 merge window and are now targeting v7.4. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why did AMD drop the sysfs-based configuration API from its UALink Linux kernel patches? AMD decided to remove the sysfs-based configuration API from the updated UALink patch series and instead rely on out-of-band tooling, at least initially, for handling UALink configuration. This change appeared in the version 2 series of patches posted in late August, alongside a fix for 32-bit kernel build issues. _Track kernel-level infrastructure shifts like UALink configuration handling as they land, via daily.dev._ ### Will UALink support make it into Linux kernel version 7.3? No, the UALink patches are too late for the Linux v7.3 merge window. AMD is now targeting Linux v7.4 for getting the mainline kernel UALink infrastructure merged, following a 95-patch v2 series plus a second updated series with additional documentation. _Follow kernel release timelines like this on daily.dev before planning your next upgrade._ ### What hardware does AMD's UALink over Ethernet (UALoE) support target? UALoE targets AMD's new Helios servers, which combine Instinct MI455X AI accelerators, 6th Gen AMD EPYC 'Venice' processors, and Pensando AI NICs. UALink itself is an open standard high-speed networking protocol for connecting GPUs and other AI accelerators within scale-up pods. _daily.dev helps infrastructure engineers stay current on emerging AI accelerator networking standards like UALink._ ## Similar posts on daily.dev - [AMD Posts Massive Patch Series For Enabling UALink In The Linux Kernel](https://daily.dev/posts/amd-posts-massive-patch-series-for-enabling-ualink-in-the-linux-kernel-zr1srneqw) · Phoronix · 0 upvotes · 0 comments - [AMD Sends Out Linux Patches For Their Next-Gen AIE4 NPU](https://daily.dev/posts/amd-sends-out-linux-patches-for-their-next-gen-aie4-npu-ox9fiekqj) · Phoronix · 0 upvotes · 0 comments - [AMD Updates HDMI 2.1 VRR & ALLM Patches But Will Miss Out On Linux 7.3](https://daily.dev/posts/amd-updates-hdmi-2-1-vrr-allm-patches-but-will-miss-out-on-linux-7-3-1w6ncbsje) · Phoronix · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#gpu](https://daily.dev/tags/gpu), [#amd](https://daily.dev/tags/amd) [View this post on daily.dev](https://daily.dev/posts/amd-updates-ualink-patches-to-get-the-linux-kernel-ready-for-ualoe-on-helios-tvhxjbfw4) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"AMD Updates UALink Patches To Get The Linux Kernel Ready For UALoE On Helios","url":"https://daily.dev/posts/amd-updates-ualink-patches-to-get-the-linux-kernel-ready-for-ualoe-on-helios-tvhxjbfw4","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/amd-updates-ualink-patches-to-get-the-linux-kernel-ready-for-ualoe-on-helios-tvhxjbfw4"},"datePublished":"2026-08-31T19:43:47.843Z","dateModified":"2026-08-31T21:23:22.521Z","description":"AMD has revised its large UALink patch series aimed at bringing Ultra Accelerator Link support into the mainline Linux kernel and the AMDGPU driver.
