Enum ClientCapability

#[repr(u64)]
pub enum ClientCapability {
    Stereo3D = 1,
    UniversalPlanes = 2,
    Atomic = 3,
    AspectRatio = 4,
    WritebackConnectors = 5,
    CursorPlaneHotspot = 6,
}

Used to enable/disable capabilities for the process.

Variants

Stereo3D = 1

The driver provides 3D screen control

UniversalPlanes = 2

The driver provides more plane types for modesetting

Atomic = 3

The driver provides atomic modesetting

AspectRatio = 4

If set to 1, the DRM core will provide aspect ratio information in modes.

WritebackConnectors = 5

If set to 1, the DRM core will expose special connectors to be used for writing back to memory the scene setup in the commit.

The client must enable Self::Atomic first.

CursorPlaneHotspot = 6

Drivers for para-virtualized hardware have additional restrictions for cursor planes e.g. they need cursor planes to act like one would expect from a mouse cursor and have correctly set hotspot properties. If this client cap is not set the DRM core will hide cursor plane on those virtualized drivers because not setting it implies that the client is not capable of dealing with those extra restictions. Clients which do set cursor hotspot and treat the cursor plane like a mouse cursor should set this property.

The client must enable Self::Atomic first.

Trait Implementations

impl Clone for ClientCapability

fn clone(&self) -> ClientCapability

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClientCapability

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ClientCapability

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ClientCapability

fn eq(&self, other: &ClientCapability) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
