Detailed Description

Geode roots over runtime devices that their owner opens, instead of Donner's backend selection.

Function Documentation

AdoptRuntimeDeviceSource()

std::shared_ptr< GeodeGpuRoot > donner::geode::AdoptRuntimeDeviceSource	(	std::shared_ptr< GeodeRuntimeDeviceSource >	source,
		const GeodeGpuRootCapabilities &	capabilities,
		std::shared_ptr< gpu::DeviceLostState >	lostState )

Adopts source as a Geode root of kind GpuBackendKind::External.

The root never selects or names a backend: DONNER_GPU_BACKEND, a caller's backend choice and the platform default all refuse the external kind, so only a holder of a source reaches it.

Parameters

source	Opens the runtime devices of every context over the root; must not be null.
capabilities	What every device the source opens reports identically. Its backend kind is replaced with the external kind.
lostState	Loss condition shared by the root and every device source opens; must not be null.

Returns

The root, or null when source or lostState is null.
