Module graphics 

Graphics-API interop (Runtime API).

Mirrors baracuda_driver::graphics on the Runtime side. Runtime contexts are implicit, so register_* doesn’t take a Context — it uses the current device’s primary context.

For modern Vulkan / D3D12 flows, prefer crate::external::ExternalMemory.

Workflow

1. Register the graphics resource (gl::register_buffer, d3d11::register_resource, …) — returns a GraphicsResource.
2. Call GraphicsResource::map on a stream to hand it to CUDA.
3. GraphicsResource::mapped_pointer or GraphicsResource::mapped_array → usable device memory.
4. … compute …
5. GraphicsResource::unmap releases it back to the graphics API.

Drop unregisters the resource automatically.

Modules

MapResourceFlags

CUgraphicsMapResourceFlags — map-time access hints.

RegisterFlags

CUgraphicsRegisterFlags — shared register-time flags across GL / D3D / VDPAU / EGL.

d3d9

Direct3D 9 interop (Windows).

d3d10

Direct3D 10 interop (Windows).

d3d11

Direct3D 11 interop (Windows) — the D3D path most still relevant today.

egl

EGL interop — Jetson camera / video pipelines via EGLImage + EGLStream.

gl

OpenGL interop.

nvsci

NvSci interop — query sync-object attributes CUDA expects from NvSciSync signalers / waiters. Feed the resulting NvSciSyncAttrList into libnvsciSync’s reconcile + alloc, then import the resulting object via crate::external::ExternalSemaphore::import with the NvSciSync handle type.

vdpau

VDPAU interop (Linux video-decode pipelines).

Structs

GraphicsResource

Runtime-side handle to a graphics-API resource. Drop unregisters it.
