Subject: [dpdk-dev] Question on AESNI PMD
Date: Fri, 9 Mar 2018 22:08:52 +0000 [thread overview]
Message-ID: <82C9F782B054C94B9FC04A331649C77AA6ABA2B4@fmsmsx104.amr.corp.intel.com> (raw)
Hi,
I'm working on an SPDK module that uses the DPDK cryptodev framework, initially I'm using the AESNI PMD and have a few questions. in the doc it says that only in-place is supported however I see code in set_mb_job_params() just after the comment "Mutable crypto operation parameters" it appears to support a separate src and dst m_buf so curious about that.
For my use case (storage) I'm using external data buffers so I can't use that code anyways but I was able to make some minor changes and am able to pass in different src and dst m_bufs that point to my own data buffers (not in the packet) and it seems to be working fine.
So my 2 questions are:
(1) is the documented in-place limitation simply not correct?
(2) would there be any upstream interest in supporting a patch that enables m_bufs using external data buffers for src and dst?
Thanks!
Paul
