Unable to attach 0x8086:0x37c8 QAT device to VPP+DPDK

[SuryaRudra]

Trying to use below QAT device with VPP+DPDK.

08:00.0 Co-processor [0b40]: Intel Corporation C62x Chipset QuickAssist Technology [8086:37c8] (rev 05)

But getting below error:
Unsupported PCI device 0x8086:0x37c8 found at PCI address 0000:08:00.0

Please let us know, is VPP+DPDK supports above QAT?

Hi SuryaRudra,

The error message "Unsupported PCI device 0x8086:0x37c8 found at PCI address 0000:08:00.0" indicates that the VPP (Vector Packet Processing) and DPDK (Data Plane Development Kit) setup you are using does not recognize the Intel QuickAssist Technology (QAT) device with the PCI ID 0x8086:0x37c8.

If you have a system based on Intel® C62x Chipset, you should be using Intel® QuickAssist Technology Driver for Hardware Version 1.x <https://www.intel.com/content/www/us/en/download/19734/intel-quickassist-technology-driver-for-linux-hw-version-1-x.html> and I would recommend running the latest version of DPDK <https://core.dpdk.org/download/>

Is QAT properly configured? Can you run $lsmod | grep qat, and provide the results?

Is VPP configured to use the QAT device? This may involve setting the correct device parameters in the VPP configuration files.

Is QAT device bound to the correct driver. You can use the dpdk-devbind.py script provided by DPDK to bind the device to the appropriate driver. For example: $sudo dpdk-devbind.py --bind=igb_uio 0000:08:00.0
