Old and obsolete hardware drivers continue to be pruned. Linus Torvalds has not yet posted release comments on LKML. ## Full article daily.dev links to this article rather than hosting it.

Linux 7.3-rc1 adds early enablement for upcoming AMD Zen 6 platforms, kernel driver support for the 2026 Valve Steam Controller, initial support for Apple M3 Ultra, Pro, and Max chips, new AMD graphics IP enablement, initial Intel Starfire bring-up, and out-of-the-box support for Intel Xe3P graphics paired with Nova Lake. _Track kernel hardware enablement like this on daily.dev before rolling out a new Linux release._ ### What filesystem improvements landed in Linux 7.3-rc1? Linux 7.3-rc1 delivers better Btrfs performance along with FailFS being upstreamed into the kernel for the first time. These changes are part of the broader merge window that closed after two weeks, alongside a low-latency mode added for USB4STREAM. _Developers evaluating filesystem changes can follow kernel release notes like this on daily.dev._ ## Similar posts on daily.dev - [Many Wonderful Improvements Expected For Linux 7.1, Especially For AMD & Intel](https://daily.dev/posts/many-wonderful-improvements-expected-for-linux-7-1-especially-for-amd-intel-yw9iq04eb) · Phoronix · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#gpu](https://daily.dev/tags/gpu), [#amd](https://daily.dev/tags/amd), [#steam-deck](https://daily.dev/tags/steam-deck) [View this post on daily.dev](https://daily.dev/posts/linux-7-3-rc1-with-amd-zen-6-additions-better-btrfs-performance-2026-steam-controller-z1sxtxbdo) ```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":"Linux 7.3-rc1 With AMD Zen 6 Additions, Better Btrfs Performance & 2026 Steam Controller","url":"https://daily.dev/posts/linux-7-3-rc1-with-amd-zen-6-additions-better-btrfs-performance-2026-steam-controller-z1sxtxbdo","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/linux-7-3-rc1-with-amd-zen-6-additions-better-btrfs-performance-2026-steam-controller-z1sxtxbdo"},"datePublished":"2026-08-30T21:53:33.348Z","dateModified":"2026-08-31T00:25:26.697Z","description":"Linux 7.3-rc1 has landed after a two-week merge window, bringing Intel hybrid CPU optimizations, early AMD Zen 6 platform enablement, improved Btrfs...","image":"https://media.daily.dev/image/upload/s--OHB84bZF--/f_auto/v1722860399/public/Placeholder%2010","thumbnailUrl":"https://media.daily.dev/image/upload/s--OHB84bZF--/f_auto/v1722860399/public/Placeholder%2010","isAccessibleForFree":true,"articleSection":"Phoronix","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Phoronix","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/6a26ba379dd64932830aa0c9803dd7ee","url":"https://daily.dev/sources/phoronix"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/linux-7-3-rc1-with-amd-zen-6-additions-better-btrfs-performance-2026-steam-controller-z1sxtxbdo","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,gpu,amd,steam-deck","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Phoronix","item":"https://daily.dev/sources/phoronix"},{"@type":"ListItem","position":3,"name":"Linux 7.3-rc1 With AMD Zen 6 Additions, Better Btrfs Performance & 2026 Steam Controller"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/linux-7-3-rc1-with-amd-zen-6-additions-better-btrfs-performance-2026-steam-controller-z1sxtxbdo#faq","mainEntity":[{"@type":"Question","name":"What new hardware support is included in Linux 7.3-rc1?","acceptedAnswer":{"@type":"Answer","text":"Linux 7.3-rc1 adds early enablement for upcoming AMD Zen 6 platforms, kernel driver support for the 2026 Valve Steam Controller, initial support for Apple M3 Ultra, Pro, and Max chips, new AMD graphics IP enablement, initial Intel Starfire bring-up, and out-of-the-box support for Intel Xe3P graphics paired with Nova Lake.
