53 build virglrenderer with Venus support and to start the vtest server,
55 .. code-block:: console
59 $ meson out -Dvenus-experimental=true
60 $ ninja -C out
61 $ ./out/vtest/virgl_test_server --venus
63 In another shell,

78 ----------
80 The driver requires ``VIRTGPU_PARAM_CONTEXT_INIT`` from the virtio-gpu kernel
81 driver, which was upstreamed in kernel 5.16.
83 crosvm is written in Rust. To build crosvm, make sure Rust has been installed
86 .. code-block:: console
88 $ git clone --recurse-submodules \
91 $ RUSTFLAGS="-L<path-to-virglrenderer>/out/src" cargo build \
92 --features "x wl-dmabuf virgl_renderer virgl_renderer_next default-no-sandbox"
94 Note that crosvm must be built with ``default-no-sandbox`` or started with
95 ``--disable-sandbox`` in this setup.

118 In this setup, the guest userspace uses Xwayland and a special Wayland
120 compositor, using Virtio-WL as the transport. This setup is more tedious, but
123 For now, the guest kernel must be built from the ``chromeos-5.10`` branch of

135 $ meson configure out -Dminigbm_allocation=true

139 ``--display-window-keyboard --display-window-mouse`` by
140 ``--wayland-sock=<path-to-wayland-socket>`` when starting crosvm.
142 In the guest, build and start sommelier, the special Wayland compositor,
144 .. code-block:: console
148 $ meson out -Dxwayland_path=/usr/bin/Xwayland -Dxwayland_gl_driver_path=/usr/lib/dri
