With the latest RADV code in Mesa Git, RADV is up to 54.7% of the tests passing in The Khronos Group's Vulkan Conformance Test Suite via VK-GL-CTS. 45.3% of the tests are not supported in the current stage of RADV.
Airlie commented on his blog post about the RADV conformance matter, "That is pretty conformant (in fact it would pass as-is). However I need to clean up the patches in the branch and maybe figure out how to do some bits properly without hacks (particularly some semaphore wait tweaks), but that is most of the work done."
AMDGPU-PRO has passed its conformance testing and is conformant for Vulkan but great to see RADV making so much progress without the official support of AMD.
