Hi, I am trying to understand how are hardware xor engine's utilized by async_tx module. I don't get the exact link that connects async_tx and hardware xor engine. Could someone help me understand it. Registration of a RAID HW XOR engine happens in drivers/dma/<soc-xor.c> using dma_async_device_register(). Does this registration function connect the async_tx api's to use the HW XOR engine? Or is there anything we need to support to make async_tx api's to take advantage of the hardware XOR engine?
