We’ve previously reported that the Vulkan 1.0 conformant V3DV driver for Raspberry Pi 4 and other Broadcom BCM2711 based platforms was part of Mesa 20.3 open-source graphics framework. But at the time, it was still under development.
The good news is that Mesa 20.3 has now been released, and there’s much more than Raspberry Pi 4 support, as Collabora informed us the release also included Arm Mali Bifrost GPU support via the open-source Panfrost driver.
The latter was made possible thanks to the work by Alyssa Rosenzweig and Boris Brezillon, with Alyssa going into details in a recent blog post on Collabora. More work is still needed with better performance and OpenGL 3.1 being the focus in the months ahead.
- OpenGL 4.6 and Vulkan 1.2 APIs support
- Initial support for Intel Gen12 Alder Lake graphics and AMD Dimgrey Cavefish and VanGogh graphics
- Lavapipe Vulkan CPU-based implementation equivalent to LLVMpipe is for OpenGL has been merged
- Compute kernel support within the Intel Iris Gallium3D driver.
- On-disk shader cache support for Nouveau NVC0 and Etnaviv
- OpenCL 1.2 support for Gallium3D’s Clover
- OpenGL 3.3 for Zink
- Many other bug fixes and improvements
It should be noted that Mesa 20.3.0 is a new development release, and for people who are mostly concerned with stability and reliability, the developers recommend to stick with a previous release or wait for Mesa 20.3.1 point release.
