Subject: [dpdk-users] Queue pairs in C626 QAT Card
Date: Tue, 1 Dec 2020 10:45:31 +0000 [thread overview]
Message-ID: <AT5PR8401MB10272B03A2869CD69FAFF166ECF40@AT5PR8401MB1027.NAMPRD84.PROD.OUTLOOK.COM> (raw)
Hi,
What is the maximum number of queue pairs in C626 QAT card?
From rte_cryptodev_info_get(), it seems that the maximum number is 2. Is this correct?
Can it be increased via configuration or is this set in hardware?
I have a DPDK application running 5 instances on 5 CPUs. I need the QAT VF to be bound to each of the CPUs. But, this limitation of 2 queue pairs means that only 2 of the CPUs can communicate with QAT VF at any given point.
Regards,
Venkatesh
