I'm not sure if you've seen the rest of this conversation already from it being on the ci mailing list or not, but modinfo looks good for qat_c62x andqat_c62xvf after the custom kernel was built. From there, it should be possible to bind some VFs for each PF on the QAT card, per documentation here <a href="https://doc.dpdk.org/guides/cryptodevs/qat.html">https://doc.dpdk.org/guides/cryptodevs/qat.html</a> but it results in a seg fault like you see above. Let me know if you have any ideas. </div></div></div>
