This makes PowerPC join ARM 32-bit, ARM64, LoongArch, RISC-V, UM, and x86_64 as architectures supporting Rust in the kernel. The update also begins initial enablement work for next-generation POWER12, covering base performance monitoring, raw mode, and architected mode features, with further POWER12 work expected in future kernel cycles. The remaining POWER changes are mostly fixes and low-level updates. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does the Linux 7.3 kernel support Rust on PowerPC? Yes, Linux 7.3 adds in-kernel Rust support for PowerPC, covering both PPC32BE (32-bit big endian) and PPC64LE (64-bit little endian) architectures. The support was initially treated as experimental during development but is being merged as marked 'maintained' after a series of adjustment patches. This makes PowerPC join ARM 32-bit, ARM64, LoongArch, RISC-V, UM, and x86_64 as architectures with Rust kernel support. _Track kernel architecture support changes like PowerPC Rust enablement as they land on daily.dev._ ### What is POWER12 enablement work in the Linux kernel? Linux 7.3 begins base enablement for IBM's next-generation POWER12 processor, adding initial support for Power12 Base Performance Monitoring, Power12 raw mode, and Power12 architected mode. This is early-stage work, with more POWER12 support expected to continue in future kernel release cycles, following earlier open-source compiler activity related to POWER12. _Developers tracking new IBM POWER hardware enablement can follow kernel progress on daily.dev._ ## Similar posts on daily.dev - [Rust For Linux 7.3 Begins Seeing Fixes To Prepare For Rust's GCC Backend](https://daily.dev/posts/rust-for-linux-7-3-begins-seeing-fixes-to-prepare-for-rust-s-gcc-backend-7bzhbculc) · Phoronix · 0 upvotes · 0 comments - [IBM s390 Is The Latest Architecture Seeing Rust Linux Kernel Support](https://daily.dev/posts/ibm-s390-is-the-latest-architecture-seeing-rust-linux-kernel-support-qgyblku46) · Phoronix · 0 upvotes · 0 comments - [Kernel 7.2: RK3588 media, smarter GPU memory, and Rust foundations](https://daily.dev/posts/kernel-7-2-rk3588-media-smarter-gpu-memory-and-rust-foundations-vrpih8voj) · Collabora Blog · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#rust](https://daily.dev/tags/rust), [#ibm](https://daily.dev/tags/ibm) [View this post on daily.dev](https://daily.dev/posts/linux-7-3-on-powerpc-now-supports-in-kernel-rust-initial-power12-enablement-begins-cs4e493o7) ```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 On PowerPC Now Supports In-Kernel Rust, Initial Power12 Enablement Begins","url":"https://daily.dev/posts/linux-7-3-on-powerpc-now-supports-in-kernel-rust-initial-power12-enablement-begins-cs4e493o7","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/linux-7-3-on-powerpc-now-supports-in-kernel-rust-initial-power12-enablement-begins-cs4e493o7"},"datePublished":"2026-08-17T10:18:48.664Z","dateModified":"2026-08-17T10:19:18.500Z","description":"Linux 7.3's PowerPC pull request adds in-kernel Rust support for both PPC32BE big endian and PPC64LE little endian architectures, marking it as maintained...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/94da8d932e3cdcaaa51219cfaff2718e?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/94da8d932e3cdcaaa51219cfaff2718e?_a=AQAEuop","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-on-powerpc-now-supports-in-kernel-rust-initial-power12-enablement-begins-cs4e493o7","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,rust,ibm","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 On PowerPC Now Supports In-Kernel Rust, Initial Power12 Enablement Begins"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/linux-7-3-on-powerpc-now-supports-in-kernel-rust-initial-power12-enablement-begins-cs4e493o7#faq","mainEntity":[{"@type":"Question","name":"Does the Linux 7.3 kernel support Rust on PowerPC?","acceptedAnswer":{"@type":"Answer","text":"Yes, Linux 7.3 adds in-kernel Rust support for PowerPC, covering both PPC32BE (32-bit big endian) and PPC64LE (64-bit little endian) architectures.
