Struct virtio_drivers::VirtIOGpu

pub struct VirtIOGpu<'a> { /* private fields */ }

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

impl VirtIOGpu<'_>

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

Create a new VirtIO-Gpu driver.

pub fn ack_interrupt(&mut self) -> bool

Acknowledge interrupt.

pub fn resolution(&self) -> (u32, u32)

Get the resolution (width, height).

pub fn setup_framebuffer(&mut self) -> Result<&mut [u8]>

Setup framebuffer

pub fn flush(&mut self) -> Result

Flush framebuffer to screen.

pub fn setup_cursor(
    &mut self,
    cursor_image: &[u8],
    pos_x: u32,
    pos_y: u32,
    hot_x: u32,
    hot_y: u32
) -> Result

Set the pointer shape and position.

pub fn move_cursor(&mut self, pos_x: u32, pos_y: u32) -> Result

Move the pointer without updating the shape.
