Hi Kai,

I am reaching out to you regarding our efforts to set up a new QAT
device at the DPDK Community Lab. This is for adding a new QAT Device,
beyond the QAT PCI card that we set up and began testing last year for
an ARM Ampere System.

I've set up testing for the Intel QAT 4xxx series device, but I just
wanted to double-check that the performance metrics we are seeing from
DPDK's test-crypto-perf application look acceptable to you. We are
running a DTS testsuite which uses the dpdk-test-crypto-perf
application in throughput, latency, and verify mode for testing. If
you want to see the test plan, you can read it here:
https://git.dpdk.org/tools/dts/tree/test_plans/crypto_perf_cryptodev_perf_test_plan.rst

Could you review the test results and let me know if they seem correct
for this QAT SKU?

Here are the test results. The metrics you are looking for should be
visible in the perf_cryptodev_result.json file:

Thanks,
Cody Cheng

He is satisfied with the metrics the card is getting with DPDK (he compared them against some reports Intel has published and also what we see on a QAT PCI card on an Ampere ARM system here at UNH).

Is there any DPDK/quickassist/crypto person on your team who could serve as a contact for this purpose? If so, I think Cody can add them to this thread and share the more detailed info for that person for them to approve (or disapprove).
