Intel Quick Assist Adapter 8950-SCCP

[Huang1]

I have a Intel Quick Assist Adapter 8950-SCCP (dh895xcc).

I can not find it's driver in intel site.

Intel® QuickAssist Technology Driver for Linux* – HW Version 1.X

Intel® QuickAssist Adapter Family for Servers

Can anyone give me some hint? thanks.

Hi Huang1,

You may want to use the following driver: https://www.intel.com/content/www/us/en/download/19734/intel-quickassist-technology-driver-for-linux-hw-version-1-x.html

This driver should also work for DH8925, DH8926, DH8950 and DH8955.

There is more information available here: https://ark.intel.com/content/www/us/en/ark/products/codename/60172/products-formerly-coleto-creek.html please be aware that this product has been discontinued.

Hi Ronny,

  Thanks your kindly support on QAT 8950.

I did this on ubuntu 2204, no error appears.

1. ./configure --enable-icp-debug -enable-icp-log-syslog --enable-icp-dc-return-counters-on-error
2. make && make install 
3. make samples && make samples-install

And list it

But, when I run the sample code, there is error.

Could you give me more advice on this? thank you.

Hi Huang1,

Are you enabling sriov? I dont think you are, you are using: ./configure --enable-icp-debug -enable-icp-log-syslog --enable-icp-dc-return-counters-on-error

This error usually happends when QAT install was performed with intel_iommu=on and ./configure --enable-icp-sriov=host – verify vfs are running:

To start vfs enter: # service qat_service_vfs start

To verify vfs are running enter: # service qat_service_vfs status

If QAT install was performed with intel_iommu=on and ./configure targeting PF use only:

This particular configuration is not valid since PFs are not able to be used when IOMMU is enabled.

Hi Ronny G,

I did not enable sriov and set intel_iommu=on in ./configure step.

Actually I want to invest compression things on QAT 8950. 

Could you help me on configure it correctly?  Thank you.

Hi Huang1,

This particular configuration is not valid since PFs are not able to be used when IOMMU is enabled.

Please refer to the following website for cpa_sample_code details:

https://intel.github.io/quickassist/GSG/2.X/sampleapplications.html#performance-sample-code

Note: Before running cpa_sample_code make sure QAT is properly configured, refer to: https://intel.github.io/quickassist/GSG/2.X/installation.html

Hi Ronny_G,

Thanks your kindly help.

I performance the test on a Intel CPU (Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz) (previously on a AMD).

Configured as:

./configure --enable-icp-debug --enable-icp-dc-return-counters-on-error --enable-icp-dc-only

The samples_code works:

Thank you very much on QAT env setup.

I will invest on compression test.

This ticket can be closed. I will raise new if having problem on compression test.
