/**
 * Native bindings to the amd_bus_addressable_memory extension.
 * 
 * 

This extension defines an API that allows improved control of the physical memory used by the graphics device.

* *

It allows to share a memory allocated by the Graphics driver to be used by other device on the bus by exposing a write-only bus address. One example of * application would be a video capture device which would DMA into the GPU memory.

* *

It also offers the reverse operation of specifying a buffer allocated on another device to be used for write access by the GPU.
