If you take a look at the conformant vulkan list, you might see entry 220. Software in the Public Interest, Inc. 2017-10-04 Vulkan_1_0 220 AMD Radeon R9 285 Intel i5-4460 x86_64 Linux 4.13 X.org DRI3. This is radv, and this is the first conformance submission done under the X.org (SPI) membership of the Khronos adopter program. This submission was a bit of a trial run for radv developers, but Mesa 17.2 + llvm 5.0 on Bas's R9 285 card. We can extend this submission to cover all VI GPUs. In practice we pass all the same tests on CIK and Polaris GPUs, but we will have to do complete submission runs on those when we get a chance. But major milestone/rubberstamp reached, radv is now a conformant Vulkan driver. Thanks go to Bas and all the other contributors and people who's code we've leveraged!
