Mesa 21.1's Lavapipe Now Teases Vulkan 1.1 On CPUs

This quarter's Mesa 21.1 feature release will continue to offer more improvements for Lavapipe, the CPU-based software Vulkan implementation. The latest today is Vulkan 1.1 now being advertised.

Lavapipe with Mesa 21.1-devel is now advertising Vulkan 1.1 rather than Vulkan 1.0. But the big caveat is this CPU-based Vulkan driver is not yet a fully conformant Vulkan implementation. Lavapipe is still missing some bits needed to completely pass Vulkan 1.0 conformance tests. But what has changed is Lavapipe now supporting the delta to get to Vulkan 1.1, per the note by David Airlie.

So all the Vulkan 1.1 specific features are ready so that is now exposed. Vulkan 1.2 features might also be finished up soon but as for when it will be officially conformant as tested by the Vulkan CTS remains to be seen.

In any case it is great seeing the continued progress on Lavapipe.
