Struct SharedGpuContext

Source

pub struct SharedGpuContext {
    pub device: Device,
    pub queue: Queue,
    pub instance: Instance,
    pub adapter: Adapter,
    pub adapter_caps: GpuAdapterCaps,
    pub enabled_features: GpuFeatureCaps,
    pub timestamps_supported: bool,
    pub timestamp_period_ns: f32,
}

Fields§

§device: Device§queue: Queue§instance: Instance

The wgpu instance — needed to create surfaces (must be same instance as adapter).

§adapter: Adapter

The wgpu adapter — needed to create surfaces and query capabilities.

§adapter_caps: GpuAdapterCaps

Immutable adapter capability snapshot for diagnostics and feature negotiation.

§enabled_features: GpuFeatureCaps

Feature subset actually requested on the process-wide device.

§timestamps_supported: bool

Whether TIMESTAMP_QUERY was negotiated on this device (adapter-dependent). When false, the LLM GPU profiler degrades to a no-op (CPU wall-clock only).

§timestamp_period_ns: f32

Nanoseconds per timestamp tick (Queue::get_timestamp_period); 0.0 when unsupported.

Implementations§

Source §

impl SharedGpuContext

Source

pub fn queue_for_lane(&self, lane: QueueLane) -> &Queue

Logical queue lane for universe-tagged dispatch (B2.3). Single physical wgpu::Queue today; lane tags preserve driver scheduling intent.

Source

pub fn queue_for_universe(&self, universe: ComputeUniverse) -> &Queue
