-Buffer Sharing and Synchronization
-----------------------------------
-
-The dma-buf subsystem provides the framework for sharing buffers for
-hardware (DMA) access across multiple device drivers and subsystems, and
-for synchronizing asynchronous hardware access.
-
-This is used, for example, by drm "prime" multi-GPU support, but is of
-course not limited to GPU use cases.
-
-The three main components of this are: (1) dma-buf, representing a
-sg_table and exposed to userspace as a file descriptor to allow passing
-between devices, (2) fence, which provides a mechanism to signal when
-one device as finished access, and (3) reservation, which manages the
-shared or exclusive fence(s) associated with the buffer.
