Class NVStreamDMA

java.lang.Object

org.lwjgl.egl.NVStreamDMA

public final class NVStreamDMA
extends java.lang.Object

Native bindings to the NV_stream_dma extension.

This extension provides the framework for performing DMA transfers between opposite ends of a single stream, if there is no shared memory available between them.

In case of cross system streams the buffer contents of one end of the stream is transferred to other end using sockets by EGL_NV_stream_socket extension. Transferring buffer contents through sockets is slower compared to DMA transfers. Since DMA transfers have higher throughput compared to sockets, using EGL_NV_stream_dma extension, applications can request EGL to utilize DMA channels to perform buffer copies.

Requires NV_stream_remote and NV_stream_cross_system.
