The DRI3 extension provides mechanisms to translate between direct rendered buffers and X pixmaps. When combined with the Present extension, a complete direct rendering solution for OpenGL is provided. The direct rendered buffers are passed across the protocol via standard POSIX file descriptor passing mechanisms. On Linux, these buffers are DMA-BUF objects. DRI3 also includes a mechanism to translate between Linux Futexes and X Sync extension Fences. This provides a synchronization mechanism which can be used to serialize access to shared render buffers.
