Collabora engineers presented three sessions: a lightning talk on the journey from GPU reverse-engineering to driver development (Panfrost), a talk on graphics tracing using Perfetto and the gfx-pps project for capturing GPU performance counters, and a talk on using VKMS (virtual KMS) to run DRM-backend tests in Weston's GitLab CI pipeline. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is gfx-pps and how does it work with Perfetto for GPU profiling? gfx-pps is a project started by Collabora that provides components which, together with Google's Perfetto, let you capture a trace and visualize GPU performance counters or any kind of timeline through a web-based UI. It is designed to help identify GPU bottlenecks and guide optimization efforts in graphics applications. _GPU performance work like this surfaces regularly for Linux graphics developers on daily.dev._ ### What is VKMS and why is it useful for DRM backend testing in CI? VKMS (Virtual KMS) is a virtual kernel mode-setting device that allows DRM-backend tests to run on headless machines without physical display hardware. Weston uses it to automatically run DRM-backend tests in its GitLab CI pipeline, extending test coverage without requiring real hardware. _Developers working on Wayland or DRM CI pipelines can track VKMS developments on daily.dev._ ## Similar posts on daily.dev - [Panfrost, Kraid, Tyr, and more at XDC 2026](https://daily.dev/posts/panfrost-kraid-tyr-and-more-at-xdc-2026-rxhyon6pb) · Collabora Blog · 0 upvotes · 0 comments - [XDC 2026 Will Feature Many Interesting Talks: Vulkan Gallium, OpenCL On CUDA & More](https://daily.dev/posts/xdc-2026-will-feature-many-interesting-talks-vulkan-gallium-opencl-on-cuda-more-3holubtga) · Phoronix · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#cicd](https://daily.dev/tags/cicd), [#mesa](https://daily.dev/tags/mesa) [View this post on daily.dev](https://daily.dev/posts/x-org-developer-s-conference-2020-4wespo39q) ```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":"X.Org Developer's Conference 2020","url":"https://daily.dev/posts/x-org-developer-s-conference-2020-4wespo39q","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/x-org-developer-s-conference-2020-4wespo39q"},"datePublished":"2026-08-11T08:56:15.500Z","dateModified":"2026-08-11T09:34:49.180Z","description":"XDC 2020, the X.Org Developer's Conference, took place entirely online for the first time.
