Hello, I read the readme about dma API, but still don't understand how it should be used It is said that dma_alloc_coherent is responsible for allocating the buffer. 1. But how to trigger the dma transaction to start ? 2. Is there a callback when it is finished ? Thank you, Ran _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
