Key highlights include: Enric adding support for the Analogix anx78xx DRM Bridge and SD card fixes on OMAP igep00x0; Gustavo de-staging the Android sync_file framework to enable explicit fencing in the graphics pipeline and cleaning up legacy vblank helpers; Helen Koike separating the V4L2 Test Pattern Generator into its own module; Robert Foss improving DRM documentation and fixing a drm/vc4 (Raspberry Pi) atomic_commit bug; and Tomeu fixing two Rockchip issues while working on intel-gpu-tools cross-platform support. ## Full article daily.dev links to this article rather than hosting it.

The sync_file framework (Android Sync framework) was de-staged in Linux 4.7 to add explicit fencing support to the graphics pipeline. The de-staging involved refactoring SYNC IOCTLs, moving headers to dma-buf, dropping internal helpers like sync_file_install() and sync_file_put(), and adding DocBook documentation for the framework. _Developers working on Linux graphics pipelines track kernel fencing changes like these on daily.dev._ --- Tags: [#open-source](https://daily.dev/tags/open-source), [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-7-jrfmbncfs) ```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 4.7","url":"https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-7-jrfmbncfs","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/collabora-contributions-to-linux-kernel-4-7-jrfmbncfs"},"datePublished":"2026-08-11T08:54:06.254Z","dateModified":"2026-08-11T09:21:39.478Z","description":"Collabora engineers made 36 contributions to Linux Kernel 4.7.
