Struct DeviceCommitter 

pub struct DeviceCommitter<'a> {
    pub commits: usize,
    /* private fields */
}

A TestCommitter that issues real TEST_ONLY commits.

Builds a fresh request per test that (a) disables every candidate plane not in the assignment, then (b) applies each assigned layer’s properties — the order matters for the reason emit_disable describes.

Fields

commits: usize

How many test commits have been issued, for diagnostics.

Implementations

impl<'a> DeviceCommitter<'a>

pub fn new( device: &'a Device, map: &'a PlanePropertyMap, registry: &'a PlaneRegistry, crtc_index: u32, flags: AtomicCommitFlags, modeset: Option<&'a Modeset<'a>>, ) -> Self

A committer over the planes this CRTC could use.

The candidate list comes from force_disable_candidates rather than being supplied, so a test commit and the apply commit that follows it clear exactly the same set. Handing them different lists would let a configuration pass TEST_ONLY and then be applied with a plane the test had cleared still live.

Trait Implementations

impl TestCommitter for DeviceCommitter<'_>

fn lit_planes(&mut self, crtc_id: u32) -> Option<Vec<u32>>

The planes the kernel has lit on crtc_id right now, whoever lit them; None when the committer cannot tell.

fn test_assignment( &mut self, assignment: &[(u32, LayerRef<'_>)], ) -> Result<(), TestFailure>

Validate an assignment with a TEST_ONLY commit.

fn set_extra_plane(&mut self, plane_id: u32, layer: Layer)

Arm one more plane in every test, alongside the assignment.

fn clear_extra_plane(&mut self)

Stop arming the plane set by TestCommitter::set_extra_plane.
