Struct CrtcCapabilities 

#[non_exhaustive]
pub struct CrtcCapabilities {
    pub crtc_id: u32,
    pub degamma_lut_size: u32,
    pub gamma_lut_size: u32,
    pub has_degamma_lut: bool,
    pub has_ctm: bool,
    pub has_gamma_lut: bool,
}

What one CRTC’s color pipeline can be asked to do.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

crtc_id: u32

The CRTC this describes.

degamma_lut_size: u32

Rows the driver expects in a DEGAMMA_LUT blob. Zero if absent.

gamma_lut_size: u32

Rows the driver expects in a GAMMA_LUT blob. Zero if absent.

has_degamma_lut: bool

Whether DEGAMMA_LUT is exposed.

has_ctm: bool

Whether CTM is exposed.

has_gamma_lut: bool

Whether GAMMA_LUT is exposed.

Implementations

impl CrtcCapabilities

pub fn probe(device: &Device, crtc_id: u32) -> Result<Self>

Read a CRTC’s color-pipeline properties.

Errors

As ConnectorCapabilities::probe.

pub fn from_properties(properties: &PropertyStore, crtc_id: u32) -> Self

As CrtcCapabilities::probe, from a cache the caller already filled in.

pub const fn has_full_pipeline(&self) -> bool

Whether the CRTC has the whole degamma, matrix, gamma pipeline.

False on a driver exposing only part of it – vkms has GAMMA_LUT and nothing else – even though the stages it does have are usable.
