The Vulkan bits are implemented in ANV and RADV and the GL bit is implemented in radeonsi but we don't have a good test plan at the moment.  Because any such tests necessarily go across APIs, they can't really be put into the Vulkan CTS or the OpenGL CTS.  This makes piglit the natural place to put such tests.

In that case, they really need to be able to test Vulkan <-> D3D11 interop as well as Vulkan <-> GL.  One could imagine, for instance, that maybe DXVK would like to implement such interop on top of Vulkan <-> Vulkan interop in which case they would need tests.

Sounds like the right place to me.
