Key highlights include a new Red-Black tree API for BPF programs, BPF trampoline support extended to s390x and RISC-V RV64, and the removal of the legal name requirement for kernel contributions (now allowing pseudonyms). On the hardware side, initial RK3588 board support (Rock 5 Model A and B) was merged, enabling basic serial, MMC, and ethernet. MediaTek MT8192-based Acer Chromebook 514 received display and audio support. Collabora's engineering team contributed over 300 patches across DRM, power supply, MediaTek drivers, and Rockchip SoC enablement. ## Full article daily.dev links to this article rather than hosting it.

Linux kernel 6.3 merged initial RK3588 board support focused on basic features: serial, MMC, and ethernet. Specifically, Sebastian Reichel added support for the Rock 5 Model A and Rockchip's RK3588 evaluation board, while Christopher Obbard added initial support for the Rock 5 Model B. More features were already queued in linux-next targeting the v6.4 cycle. _Developers bringing up RK3588 boards track kernel enablement progress on daily.dev._ ### What changed about the Linux kernel contributor name policy? Linus Torvalds lifted the requirement to use a legal name for kernel contributions. The updated Developer Certificate of Origin now allows contributors to use any known identity, including pseudonyms or nicknames. This change, reversing a policy in place since 2006, aims to increase inclusivity for contributors who go by a preferred name that differs from their legal name. _Kernel community policy changes like this one surface quickly for contributors following Linux on daily.dev._ ### What is BPF trampoline and which architectures got support for it in Linux 6.3? BPF trampoline is critical infrastructure in the BPF subsystem that converts native calling conventions to BPF calling conventions, enabling features like fentry, fexit, and fmod_ret. In Linux 6.3, BPF trampoline support was extended to two additional architectures: s390x and RISC-V RV64. _Engineers working with BPF on non-x86 architectures find architecture-specific kernel updates on daily.dev._ ## Similar posts on daily.dev - [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) [View this post on daily.dev](https://daily.dev/posts/kernel-6-3-mediatek-rockchip-rk3588-more-oaaph9mer) ```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":"Kernel 6.3: MediaTek, Rockchip RK3588 & more","url":"https://daily.dev/posts/kernel-6-3-mediatek-rockchip-rk3588-more-oaaph9mer","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/kernel-6-3-mediatek-rockchip-rk3588-more-oaaph9mer"},"datePublished":"2026-08-11T08:55:22.523Z","dateModified":"2026-08-11T09:07:48.015Z","description":"Linux Kernel 6.3 has been released, bringing thousands of new lines of code covering core kernel improvements, architectural support, networking, and...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9961b9ed73fc2daf9c800c44112c4e7a?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9961b9ed73fc2daf9c800c44112c4e7a?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Collabora Blog","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":"Collabora Blog","logo":"https://media.daily.dev/image/upload/s--ZGZ0FjqS--/f_auto,q_auto/v1786438306/logos/collabora?_a=BAMAMicg0","url":"https://daily.dev/sources/collabora"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/kernel-6-3-mediatek-rockchip-rk3588-more-oaaph9mer","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,rust","timeRequired":"PT5M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collabora Blog","item":"https://daily.dev/sources/collabora"},{"@type":"ListItem","position":3,"name":"Kernel 6.3: MediaTek, Rockchip RK3588 & more"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/kernel-6-3-mediatek-rockchip-rk3588-more-oaaph9mer#faq","mainEntity":[{"@type":"Question","name":"What hardware support was added for Rockchip RK3588 in Linux kernel 6.3?","acceptedAnswer":{"@type":"Answer","text":"Linux kernel 6.3 merged initial RK3588 board support focused on basic features: serial, MMC, and ethernet.
