Hi Fiona,

Appreciate your response!  The thing is that this issue suddenly popped up after the kernel upgrade - I just quickly kexeced into the older version (5.5) and QAT driver was compiled against its source without any hiccups.
By briefly diffing two kernel sources, it seems that it relates to changes introduced in timekeeping32.h and time.h. In the former, getnstimeofday(), that's used by QAT driver, is not declared anymore. As for the latter, #ifndef __KERNEL__ now hides the time* types. Commits that introduced this:

c766d1472c70d25ad475cf56042af1652e792b23 - time.h
412c53a680a97cb1ae2c0ab60230e193bee86387 - timekeeping32.h

So I think some changes needs to be done in the actual driver code. But I will try to reach out to folks at 01.org.

Thanks again for your quick reply! 🙂

Regards,
Michal

Hi Michal,

The driver below isn't the DPDK QAT driver, it's the one from 01.org, so the support from that is on the 01.org forum.
Release notes https://01.org/sites/default/files/downloads/336211-014-qatforlinux-releasenotes-hwv1.7_0.pdf
give this link for support:
https://premier.intel.com

That said, it looks to me like missing development headers or similar. Have you followed the steps in the GSG here:
https://01.org/sites/default/files/downloads//336212-006qatsw-gettingstarted.pdf ?
