FreeBSD QAT - Only 2 instances, why?

JamesElstone — Mon, 21 Oct 2024 12:43:05 GMT

Hi All,

First time poster here, but looking for some help please.

I want to know why FreeBSD is locked to only use two (2) engines / instances, whereas the hardware I have can support up to 12 instances/engines?

E.G. only 2/12 engines are being used, whereas the remaining 10/12 sit idle, and no interrupts occur.

Can anyone let me know if this is a limitation within the Intel QAT driver or is a limitation in the way FreeBSD implement the QAT driver into their CryptoDev framework please?

James.

Hi James,

Thanks for reaching out to Intel Communities.

It may be possible that you only have 2 QAT devices bound to a process. Please run the following commands to better understand the current situation:

$ lsmod | grep qat

$ adf_ctl status

$ lspci -k | grep -A 3 QAT

It will also be beneficial to understand how QAT was configured and what kind of work QAT is doing. Please provide me with the details.

Regards,

Ronny G
