virtio_drivers::device::gpu

Struct VirtIOGpu

Source
pub struct VirtIOGpu<H: Hal, T: Transport> { /* private fields */ }
Expand description

A virtio based graphics adapter.

It can operate in 2D mode and in 3D (virgl) mode. 3D mode will offload rendering ops to the host gpu and therefore requires a gpu with 3D support on the host machine. In 2D mode the virtio-gpu device provides support for ARGB Hardware cursors and multiple scanouts (aka heads).
