RADV Vulkan Driver Now Has Working Support For Radeon RX Vega GPUs

Thanks to the great work done by Dave Airlie, Bas Nieuwenhuizen, and other open-source contributors, the RADV open-source Radeon Vulkan driver has re-enabled support for the Radeon RX Vega graphics processors.

The Vega/GFX9 RADV support was temporarily disabled due to bugs in this unofficial Radeon Vulkan driver, but now things seem to be in shape after the latest round of RADV/GFX9 commits.

In reverting the earlier disable, David Airlie commented, " With the two previous commits, vega shouldn't be unstable, doesn't pass CTS, but can do a complete run, and games shouldn't hang anymore, so bring it back online."

These RADV fixes are also candidates to backporting to Mesa 17.2, so this support should in turn put Vega on Vulkan working out for the Mesa 17.2.1 point release in a few weeks. Keep in mind the other Linux requirements for Vega, namely the need for updated firmware/microcode files and especially the need to be using an out-of-tree kernel code for AMDGPU in order to have the DC display code for working display support.

I'll be doing some fresh Mesa 17.3 Git benchmarks of RadeonSI OpenGL and RADV Vulkan with the RX Vega 56 and RX Vega 64 in the next few days.
