    pub struct VirtIOGpu<'a> { /* 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).

## Implementations

source

### impl VirtIOGpu<'_>

source

#### pub fn new(header: &'static mut VirtIOHeader) -> Result<Self>
