vulkan support in qemu with virgil

[Tomeu Vizoso]

Hi all,

At Collabora we have started looking at Vulkan support in QEMU with Virgil.

We have seen the work that Vivek has submitted to support the new 
virtio-gpu BLOB API (thanks!) and have identified a few holes that are 
still needed for Vulkan support.

We would like to know if anybody else is working on Vulkan support or on 
common tasks such as host-side blobs, CONTEXT_INIT, CROSS_DEVICE, 
HOST_VISIBLE, venus capsets, a new DisplayChangeListenerOps 
implementation, etc.

Thanks,

Tomeu
