From Bookworm to Trixie: Upgrading the Raspberry Pi graphics stack
K.4.601 | Day 2 | 10:30 - 10:55 | Speakers: José María Casanova Crespo
Abstract
In October 2023, when Raspberry Pi 5 was announced, a new version of Raspberry Pi OS based on Debian 12 Bookworm was released. After two years, in October 2025, the new release based on Debian 13 Trixie was released.
This talk will review what improvements have been made in the graphics stack of the Raspberry Pi, focusing on the kernel (v3d) and user space (v3d/v3dv) GPU driver upgrades.
Now all Trixie Raspberry Pi users are taking advantage of Mesa 25.0.7. It exposes Vulkan 1.3 and OpenGL 3.1 with significant performance improvements on Raspberry Pi 4/5.
We will also review what could be expected based on current and upcoming development cycles - from Mesa 25.0 to the latest upstream work - and how these advances improve the capabilities on the Raspberry Pi platform.
