Key contributions include Exynos Chromebook support in ARM multi_v7_defconfig, multi Embedded Controller support for newer Chromebooks, EMC support for the Tegra124 platform, and initial Atomic Modesetting support for Exynos DRM devices. The Atomic Modesetting interface unifies screen updates (mode changes, pageflips, plane/cursor updates) into a single IOCTL for atomic execution. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the Atomic Modesetting interface in the Linux DRM subsystem? Atomic Modesetting is a DRM interface that allows all screen updates — mode changes, pageflips, and plane/cursor updates — to happen within a single IOCTL, so everything is updated atomically. Initial support for Atomic Modesetting on Exynos devices was added in Linux 4.2, along with the CRTC state mode property that lets userspace configure a modeset applied via the atomic ioctl. _Developers working on Linux graphics and display drivers track DRM subsystem changes on daily.dev._ --- Tags: [#linux](https://daily.dev/tags/linux), [#arm](https://daily.dev/tags/arm) [View this post on daily.dev](https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-2-efaq9vfku) ```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 4.2","url":"https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-2-efaq9vfku","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-2-efaq9vfku"},"datePublished":"2026-08-11T08:56:53.615Z","dateModified":"2026-08-11T09:43:49.866Z","description":"Collabora engineers contributed 63 patches to Linux Kernel 4.2.
