==== Vulkan ====
The [[Khronos Group]] officially announced [[Vulkan API]] in March 2015, and officially released Vulkan 1.0 on 16 February 2016. Vulkan breaks compatibility with OpenGL and completely abandons its monolithic state machine concept. The developers of Gallium3D called Vulkan to be something along the lines of Gallium3D 2.0 – Gallium3D separates the code that implements the OpenGL state machine from the code that is specific to the hardware.

Version 1.3 is immediately available with Mesa 22.0. Hardware with support of OpenGL ES 3.1 should run at Vulkan Level 1.3 and before.<ref>{{cite web | url=https://www.phoronix.com/scan.php?page=article&item=vulkan-13-2022&num=1 | title=Vulkan 1.3 Released with Dynamic Rendering in Core, New Roadmap Guidance for Modern GPUs }}</ref>

As Gallium3D ingests TGSI, Vulkan ingests SPIR-V ([[Standard Portable Intermediate Representation]] version "V" as in "Vulkan").

Intel released their implementation of a Vulkan driver for their hardware the day the specification was officially released, but it was only mainlined in April and so became part of Mesa 12.0, released in July 2016. While already the i965 driver wasn't written according to the Gallium3D specifications, for the Vulkan driver it makes even less sense to flange it on top of Gallium3D. Similarly there is no technical reason to flange it with NIR, but yet Intel's employees implemented their Vulkan driver that way.<ref>{{cite web|url=https://www.x.org/wiki/Events/XDC2016/Program/ekstrand_vulkan.pdf |title=Program |website=www.x.org }}</ref>

It is to be expected that AMD's own proprietary Vulkan driver, which was released in March{{when|reason=The year is unclear|date=May 2022}}, and was announced to be released as free and open-source software in the future and be mainlined into Mesa, also abandons Gallium3D.<ref>{{cite web|url=http://www.phoronix.com/scan.php?page=article&item=radv-hits-mesa&num=1|title=Radeon Vulkan Driver Added To Mesa, Fresh Radeon Vulkan vs. OpenGL Benchmarks + AMDGPU-PRO - Phoronix|website=Phoronix.com|access-date=1 August 2018}}</ref>

Actual is Full support of Vulkan 1.0 and 1.1 since Mesa 18.1.

Nvidia released their proprietary GeForce driver with Vulkan support at launch day and Imagination Technologies (PowerVR), Qualcomm (Adreno) and ARM (Mali) have done the same or at least announced proprietary Vulkan drivers for Android and other operating systems. But when and whether additional free and open-source Vulkan implementations for these GPUs will show up, remains to be seen.
