Following the release of Mesa 25.2 from two weeks ago, Mesa 25.2.1 is out now as the first point release. Mesa 25.2.1 is quite heavy on bug fixes and some other notable back-ports from Mesa 25.3-devel.
First up, Mesa 25.2.1 fixes the NVIDIA Kepler GPU support with the NVK open-source Vulkan API driver. A mix-up when landing the Blackwell support for Mesa 25.2 ended up removing Kepler from the conformant checking function… That is now addressed with Mesa 25.2.1 for ensuring the Kepler NVK support is in good shape.
Over on the Intel side, the Intel OpenGL and Vulkan drivers now recognize the Battlemage graphics card with the 0xe209 PCI device ID. The 0xe209 device ID is a recent addition made to Intel’s Linux driver and it not yet being known for which product will ultimately be released using this device ID in the Battlemage family.
Mesa 25.2.1 also back-ports the Intel change for disabling 16x MSAA support with Xe3 Graphics. Intel is phasing out 16x multi-sample anti-aliasing support and won’t even be supported with some of the Xe3 variants and thus is being disabled outright in the driver for those next-gen Intel GPUs.
On the Radeon side, Mesa 25.2.1 adds a RADV AV1 Vulkan Video encode/decode workaround for GFX1153 graphics.
Mesa 25.2.1 also brings some fixes to the aging R600 Gallium3D driver, several Rusticl fixes for OpenCL support, RADV now only exposes indirect ray-tracing on AMD GFX7+ hardware, and a variety of other fixes.
The full list of fixes for the Mesa 25.2.1 release can be found via the mailing list announcement.
