Questions tagged [mesa]

A free and open source implementation of graphics and compute APIs such as Vulkan, OpenGL and OpenCL. Typically used in GNU/Linux on AMD or Intel GPUs. Use this tag for questions about issues in your code running on Mesa or in questions about compiling Mesa itself.

Mesa 3D is a free and open source library that implements graphics and APIs such as Vulkan, OpenGL and OpenCL (among others) with support for hardware acceleration on several different types of GPUs.

Supported hardware are Intel and AMD GPUs, along with several GPUs that are found in ARM chips, such as Adreno, Mali, Vivante and V3D. There is also a driver for NVidia GPUs, however it is somewhat limited on modern chips.

The latest releases can be found on the official website, and here is a list of the supported feature set for each driver.
