It’s an exciting time for Mesa as its next major release is unveiled +this week. Igalia has played an important role in this milestone, with +Eric Engestrom managing the release and 11 other Igalians contributing +over 110 merge requests. A sample of these contributions are detailed +below.

+

radv: Implement +vk.check_status

+

As part of an effort to enhance the reliability of GPU resets on +amdgpu, Tony implemented a GPU reset notification feature in the RADV +Vulkan driver. This new function improves the robustness of the RADV +driver. The driver can now check if the GPU has been reset by a +userspace application, allowing the driver to recover their contexts, +exit, or engage in some other appropriate action.

+ +

turnip: KGSL backend rewrite

+

With a goal of improving feature parity of the KGSL kernel mode +driver with its drm counterpart, Mark has been rewriting the backend for +KGSL. These changes leverage the new, common backend Vulkan +infrastructure inside Mesa and fix multiple bugs. In addition, they +introduce support for importing/exporting sync FDs, pre-signalled +fences, and timeline semaphore support.

+

If you’re interested in taking a deeper dive into Mark’s changes, you +can read the following MR:

+ +

turnip: a7xx +preparation, transition to C++

+

Danylo has adopted a significant role for two major changes inside +turnip: 1)contributing to the effort to migrate turnip to C++ and +2)supporting the next generation a7xx Adreno GPUs from Qualcomm. A more +detailed overview of Danylo’s changes can be found in the linked MRs +below:

v3d/v3dv various fixes +& CTS conformance

+

Igalia maintains the v3d OpenGL driver and v3dv Vulkan drive for +broadcom videocore GPUs which can be found on devices such as the +Raspberry Pi. Iago, Alex and Juan have combined their expertise to +implement multiple fixes for both the v3d gallium driver and the v3dv +vulkan driver on the Raspberry Pi. These changes include CPU performance +optimizations, support for 16-bit floating point vertex attributes, and +raising support in the driver to OpenGL 3.1 level functionality. This +Igalian trio has also been addressing fixes for conformance issues +raised in the Vulkan 1.3.5 conformance test suite (CTS).

ci, build system, and cleanup

+

In addition to managing the 23.1 release, Eric has also implemented +many fixes in Mesa’s infrastructure. He has assisted with addressing a +number of CI issues within Mesa on various drivers from v3d to panfrost. +Eric also dedicated part of his time to general clean-up of the Mesa +code (e.g. removing duplicate functions, fixing and improving the +meson-based build system, and removing dead code).
