Yes, basically I am trying to see if I can make OpenSSL use certain 'pre-defined' bufs that will be mmap'ed to a known location in the memory. So that in the HW cryptolib I can make use of DMA to supply data to the crypto engine and read back to the same physical address. That way it will be faster and I can free up the processor. So before trying to do that myself I thought of checking if this has already been thought of and if there is a way to already do it. Any suggestions on how[complex] much of code change would that be?
