This Vulkan layer can be used to do GPU offloading. Typically you want to display an image rendered on a more powerful GPU on a display managed by an internal GPU.
It is basically the same as Primus for OpenGL (https://github.com/amonakov/primus). However it does not wrap the Vulkan API from the application but is directly integrated into Vulkan as a layer (which seems to be the intendend way to implement such logic).
It's a forked project to build rpm bugs related to functionality should go here: https://github.com/felixdoerre/primus_vk
