Key work included Gustavo Padovan's extensive Exynos DRM improvements — notably asynchronous atomic commit support and enabling the atomic modesetting interface for userspace — plus removal of the exynos_drm_display and exynos_drm_encoder struct layers to simplify the codebase. Other contributors fixed clock definitions, GPIO probe deferral, USB chipidea issues, and added Tegra gpio-ranges and cpuidle_state.enter_freeze() support. ## Full article daily.dev links to this article rather than hosting it.

Linux kernel 4.3 brought significant Exynos DRM improvements: asynchronous atomic commit support (scheduling updates and returning immediately to userspace, similar to the old PageFlip API), enabling the atomic modesetting interface for userspace, and removal of the exynos_drm_display and exynos_drm_encoder struct layers to make the code cleaner and easier to maintain. _Kernel developers tracking DRM subsystem changes find coverage like this on daily.dev._ --- Tags: [#tech-news](https://daily.dev/tags/tech-news), [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-3-octnoeojf) ```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":"Collabora contributions to Linux Kernel 4.3","url":"https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-3-octnoeojf","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-3-octnoeojf"},"datePublished":"2026-08-11T08:54:06.384Z","dateModified":"2026-08-11T09:25:55.602Z","description":"Collabora developers contributed 48 patches to Linux kernel 4.3.
