+Translation of Vulkan API calls is supported since release of `virglrenderer`_
+v1.0.0 using `venus`_ protocol. ``Venus`` virtio-gpu capability set ("capset")
+requires host blob support (``hostmem`` and ``blob`` fields) and should
+be enabled using ``venus`` field. The ``hostmem`` field specifies the size
+of virtio-gpu host memory window. This is typically between 256M and 8G.
