PanVK Extension Sprint: Mesa 26.1

Mon, 20 Apr 2026 00:00:00 +0000

Last week marks the Mesa 26.1 branch point, and I wanted to take a moment to look back at what happened on the PanVK front.

Spoiler: it was a busy one.

The landscape

PanVK - the Vulkan driver for Arm Mali GPUs (Valhall and newer) - is a collaborative effort. Collabora has been doing incredible work on the compiler backend and the foundational infrastructure. Arm themselves are actively contributing to the open source Mali GPU stack as well, reviewing patches and pushing driver quality forward. On the Igalia side, my focus this cycle was Vulkan extension coverage. The kind of work that doesn’t make for flashy demos but is absolutely critical for real-world application compatibility - especially for things like DXVK.
