Device 18a1 is hardware v1.8, so Hardware v1.7/v1.8 version should work.

Thanks for confirm.

So in your experience, to use C4xxx, are you using the QAT driver of Hardware v2.0 or Hardware v1.7/v1.8 in this page https://www.intel.com/content/www/us/en/developer/topic-technology/open/quick-assist-technology/overview.html ?

Thanks,

Hi Changchun,

I cannot comment on that driver version pending flag, but from my experience DPDK works with the devices you specified. You should be able to download the most recent QuickAssist driver, install it with SRIOV support and use QAT as described in the document you linked.

Hi,

According to the section 22.3.6 Available kernel drives in https://doc.dpdk.org/guides-21.11/cryptodevs/qat.html?highlight=qat , the “Driver/ver” column for device C4xxx is still in release pending status.

Yes

No

C4xxx

Does it mean that DPDK still cannot run acceleration with QAT C4xxx device? If it can, how does it work?

Thanks
