Struct drm::mode::Fb

pub struct Fb { /* fields omitted */ }

Fb is the DRM representation of frame buffer.

Either crated by a DRM api, or imported from:

• A GEM handle.
• A PRIME fd.
• A dma_buf fd.

Methods

impl Fb

fn id(&self) -> Id<Fb>

fn add(dev: &Device,
       handle: u32,
       width: u32,
       height: u32,
       bpp: u32,
       pitch: u32,
       depth: u32)
       -> Result<Fb>

Add a frame buffer using a GEM handle.

• handle: A gem handle
• (width, height): The width and height in pixels.
• bpp: Bit's per pixel (Eg: 32)
• pitch: Offset between the start of each row in bytes. (ie. width + padding)
• depth: Color depth. (Eg: 24)

There is an Api for FbAdd2, which allows for mulit-plane buffers and more useful color format selection.

fn rm(dev: &Device, id: Id<Fb>) -> Result<()>

Remove the frame buffer from DRM.

This will not happen automatically as the Fb object is not a real representation of the Frame buffer, but a struct containing metadata about it.

TODO: It might be a good idea to create a real RAII type for Fb.
