I am not sure about it, but as what I thought is Linux kernel supports many algos in async mode and sync mode, later client has to take care which one they are going to use. Any way this offload implementation is specific to Applied Micro X-Gene SoC, where we have such a dmaengine can do CRC32c. > > Cheers, > -- > Email: Herbert Xu > Home Page: http://gondor.apana.org.au/~herbert/ > PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
