Re: [dpdk-users] Crypto QAT device not found

["Pathak, Pravin" <pravin.pathak@intel.com>]

Hi Fiona -
Thanks for the reply. I tried -cdev_type HW  but it did not help.  I am not sure of DPDK supports the device on our board.
Device is with ID 37c8/c9

3d:00.0 Co-processor: Intel Corporation Device 37c8 (rev 04)
3f:00.0 Co-processor: Intel Corporation Device 37c8 (rev 04)
da:00.0 Co-processor: Intel Corporation Device 37c8 (rev 04)
3d:01.0 Co-processor: Intel Corporation Device 37c9 (rev 04)
3d:01.1 Co-processor: Intel Corporation Device 37c9 (rev 04)
3d:01.2 Co-processor: Intel Corporation Device 37c9 (rev 04)
3d:01.3 Co-processor: Intel Corporation Device 37c9 (rev 04) ........

Everything looks correct except DPDK does not see these crypto devices. It seems virtual device if I add one.
Is there any command like argument I need to pass or build option other than CONFIG_RTE_LIBRTE_PMD_QAT=y

PFs are bound to Kernel and VFs are bound to DPDK.

Anything you can spot incorrect or missing?

[Fiona] I haven't used this tool for a while, but the command line options should be similar to the dpdk-test-crypto-perf tool. For that for QAT you should whitelist the device. e.g.:
 -w 0000:3d:01.0 ( before the -- , i.e. it's an EAL parameter) and  use --devtype crypto_qat  (after the -- , it's a parameter for the application).
The terminology of --vdev changed in a recent release, so refer to the version of http://doc.dpdk.org/guides/sample_app_ug/l2_forward_crypto.html
for the cmdline options appropriate to the release you're using.
-cdev_type HW should also cause it to select QAT
