The Mesa 25.2 code is expected to be branched next week to kick off the release process for this quarter's iteration of open-source OpenGL and Vulkan drivers. As such, there's going to be a mad dash over the next week to land lingering features and other improvements for Mesa 25.2. Making it into Mesa Git today was a big set of 42 patches for the Imagination PowerVR Vulkan driver.

A three month old merge request containing many PowerVR "PVR" open-source Vulkan driver improvements have made it into Mesa 25.2.

This merge includes PowerVR compiler improvements, reworking the descriptor set code, and more. [1]The merge request explained:

"This MR contains a variety of changes, mainly:

- ISA and IR improvements in PCO

- Support for translating various ops

- Utilizing more of the common Vulkan runtime, including:

- Initial support for the reworked descriptor set code (mainly UBOs)

- Various fixups

Although these changes allow additional Vulkan dEQP tests to run, they are primarily enablement for upcoming MRs, which aim to expand on much of the basic support provided here."

Mesa 25.2 is expected to be branched around 16 July followed by Mesa 25.2-rc1. The weekly release candidates will then continue until Mesa 25.2 is ready to officially debut sometime in August.
