It is expected that processes will pass dma-buf fd between drivers, and
only using the fd themselves for mmaping and synchronisation ioctls.
However, it may be convenient for an application to read/write into the
dma-buf, for instance a test case to check the internal
dma_buf->ops->kmap interface.
It is expected that processes will pass dma-buf fd between drivers, and
only using the fd themselves for mmaping and synchronisation ioctls.
However, it may be convenient for an application to read/write into the
dma-buf, for instance a test case to check the internal
dma_buf->ops->kmap interface.
