Table 25.1.9 closes the branch with a final fix package

  • Mesa 25.1.9 arrives as the final maintenance release for the 25.1 series before its shutdown.
  • RadeonSI/VCN video fixes: HEVC on older firmware and AV1 fix on GFX1153.
  • RADV only exposes indirect ray tracing on AMD GFX7 or higher hardware.
  • Intel ANV fixes bugs (including L3 flushes) and adds flag for linear ASTC.

Table 25.1.9

Mesa's 25.1 series says goodbye with the release of Table 25.1.9, the latest maintenance patch before officially closing this branch. The publication It is run by release manager Eric Engestrom and aims to stabilize the most commonly used graphics drivers on Linux.

This closing of the cycle comes with a collection of backport corrections These fixes affect AMD and Intel components, with a particular focus on video and Vulkan path reliability. There are no drastic functional changes, but there are adjustments that improve compatibility and performance in specific situations.

Highlights of Table 25.1.9

Among the changes that come with this release, the following stand out: AMD video stack fixes, RADV capability adjustments, and improvements to the Intel ANV driver. Below are the details by area.

The team has backported several fixes related to video acceleration in RadeonSI and the VCN block, focused on improving compatibility with different firmwares and formats. These Improvements target HEVC and AV1, two codecs that are particularly sensitive to hardware differences.

  • It is corrected HEVC encoding when the system uses older firmware on AMD GPUs with VCN.
  • A is enabled AV1 decoding fix both via RadeonSI VA and RADV Vulkan Video, specifically for AMD GPUs of the GFX1153 family.
  • Others are included minor stability adjustments in the video subsystem.

In the Vulkan driver for AMD, RADV, the exposure of the ability to indirect ray tracing to GFX7 or higher hardwareThis decision aligns the driver's advertised capabilities with actual GPU support, avoiding paths that could be problematic in previous generations.

End of branch 25.1 and continuity of the cycle

Mesa 25.1.9 closes the 25.1 branch after a final set of backports. From now on, the stable line becomes 25.2, while version 25.3 continues in development as the next stable release candidate in the Mesa cycle.

For those who need the fine detail of each commit, the team has published the release announcement with the full list of changes, where all the fixes integrated in this maintenance release are documented.

Table 25.1.9 leaves the 25.1 series in a more polished state. Resolve AMD video issues, adjust capabilities in RADV and fine-tune the Intel ANV driver, while marking the natural transition to the active branches of the project.
