virtio-gpu
==========
This document explains the setup and usage of the virtio-gpu device.
The virtio-gpu device paravirtualizes the GPU and display controller.
Linux kernel support
--------------------
virtio-gpu requires a guest Linux kernel built with the
``CONFIG_DRM_VIRTIO_GPU`` option.
QEMU virtio-gpu variants
------------------------
QEMU virtio-gpu device variants come in the following form:
* ``virtio-vga[-BACKEND]``
* ``virtio-gpu[-BACKEND][-INTERFACE]``
* ``vhost-user-vga``
* ``vhost-user-pci``
**Backends:** QEMU provides a 2D virtio-gpu backend, and two accelerated
backends: virglrenderer ('gl' device label) and rutabaga_gfx ('rutabaga'
device label). There is a vhost-user backend that runs the graphics stack
in a separate process for improved isolation.
**Interfaces:** QEMU further categorizes virtio-gpu device variants based
on the interface exposed to the guest. The interfaces can be classified
into VGA and non-VGA variants. The VGA ones are prefixed with virtio-vga
or vhost-user-vga while the non-VGA ones are prefixed with virtio-gpu or
vhost-user-gpu.
The VGA ones always use the PCI interface, but for the non-VGA ones, the
user can further pick between MMIO or PCI. For MMIO, the user can suffix
the device name with -device, though vhost-user-gpu does not support MMIO.
For PCI, the user can suffix it with -pci. Without these suffixes, the
platform default will be chosen.
virtio-gpu 2d
-------------
The default 2D backend only performs 2D operations. The guest needs to
employ a software renderer for 3D graphics.
Typically, the software renderer is provided by `Mesa`_ or `SwiftShader`_.
Mesa's implementations (LLVMpipe, Lavapipe and virgl below) work out of box
on typical modern Linux distributions.
.. parsed-literal::
-device virtio-gpu
.. _Mesa: https://www.mesa3d.org/
.. _SwiftShader: https://github.com/google/swiftshader
virtio-gpu virglrenderer
------------------------
When using virgl accelerated graphics mode in the guest, OpenGL API calls
are translated into an intermediate representation (see `Gallium3D`_). The
intermediate representation is communicated to the host and the
`virglrenderer`_ library on the host translates the intermediate
representation back to OpenGL API calls.
.. parsed-literal::
-device virtio-gpu-gl
.. _Gallium3D: https://www.freedesktop.org/wiki/Software/gallium/
.. _virglrenderer: https://gitlab.freedesktop.org/virgl/virglrenderer/
virtio-gpu rutabaga
-------------------
virtio-gpu can also leverage rutabaga_gfx to provide `gfxstream`_
rendering and `Wayland display passthrough`_. With the gfxstream rendering
mode, GLES and Vulkan calls are forwarded to the host with minimal
modification.
The crosvm book provides directions on how to build a `gfxstream-enabled
rutabaga`_ and launch a `guest Wayland proxy`_.
This device does require host blob support (``hostmem`` field below). The
``hostmem`` field specifies the size of virtio-gpu host memory window.
This is typically between 256M and 8G.
At least one virtio-gpu capability set ("capset") must be specified when
starting the device. The currently capsets supported are ``gfxstream-vulkan``
and ``cross-domain`` for Linux guests. For Android guests, the experimental
``x-gfxstream-gles`` and ``x-gfxstream-composer`` capsets are also supported.
The device will try to auto-detect the wayland socket path if the
``cross-domain`` capset name is set. The user may optionally specify
``wayland-socket-path`` for non-standard paths.
The ``wsi`` option can be set to ``surfaceless`` or ``headless``.
Surfaceless doesn't create a native window surface, but does copy from the
render target to the Pixman buffer if a virtio-gpu 2D hypercall is issued.
Headless is like surfaceless, but doesn't copy to the Pixman buffer.
Surfaceless is the default if ``wsi`` is not specified.
.. parsed-literal::
