Microsoft's Dzn Mesa Driver Now Exposes Vulkan 1.1

After Microsoft engineers got Vulkan 1.0 conformance tests to nearly 100% for their Dozen "Dzn" Mesa driver, they have now enabled Vulkan 1.1 support as their next step for this Vulkan-atop-Direct3D 12 open-source implementation.

Microsoft engineers continue working on the Dozen/Dzn code for implementing the industry-standard Vulkan API atop Direct3D 12 so that it can be used on Windows in case of having no Vulkan hardware driver installed/present and for other use-cases like getting Vulkan running within Windows Subsystem for Linux atop a D3D12 host driver.

Now that the Mesa 23.1 code is in good shape for Vulkan 1.0, the quest continues with Vulkan 1.1. Prominent Microsoft Mesa contributor Jesse Natalie has merged the initial code for getting Vulkan 1.1 up and running. Some Vulkan 1.1 features were previously implemented for their Dzn driver while now in Mesa 23.1-devel is the rest of the minimal changes needed to get Vulkan 1.1 exposed.
