--- tags: QuickAssist Technology (QAT) --- # Intel QuickAssist Technology (QAT) building SOP ###### tags: QuickAssist Technology (QAT) ## Brief introduction of DPDK Point of QAT: Accelerate encrypting/decrypting and zip/unzip by HW. Program can call API of QAT, let QAT help accelerate encrypting/decrypting and zip/unzip. ## Platform Mother Board: CB-1920 CPU: Intel(R) Xeon(R) Gold 6248 CPU @ 2.50GHz*** 2 (must support QAT) OS: Ubuntu 18.04 LTS kernel 4.15.0 ## SOP ### 1.Login root ```javascript= $ sudo su ``` ### 2.Create directory (put QAT source code later) ```javascript= $ mkdir qat/ $ cd qat/ ``` ### 3.apt-get update ### 4.Install basic packages ```javascript= $ apt-get install build-essential g++ pkg-config libssl-dev zlib1g-dev libudev-dev ``` ### 5.Download and unzip QAT source package ```javascript= $ wget https://01.org/sites/default/files/downloads/qat1.7.l.4.9.0-00008.tar.gz $ tar –zxof qat1.7.l.4.9.0-00008.tar.gz //in this example, I download qat1.7.l.4.9.0-00008.tar.gz $ chmod -R 777 * ``` ### 6.Install QAT module ```javascript= $ ./configure $ make $ make install ``` ### 7.Check the installation was successful ```javascript= $ lsmod | grep qat ``` ![](https://i.imgur.com/vO2xDDc.png) ### 8.Start QAT service ```javascript= $ service qat_service start $ service qat_service status ``` ![](https://i.imgur.com/GjBlFla.png) State: up (QAT start successful) If the state: down (QAT off) Start QAT command ```javascript= $ service qat_service start ``` or Restart QAT command: ```javascript= $ service qat_service restart ``` ### 9.Install QAT cpa sample code ```javascript= $ make samples-install ``` ### 10.Execute QAT sample code ```javascript= $ cd build $ ./cpa_sample_code ``` ![](https://i.imgur.com/dFczhFw.png) You can get the test results of all the preset algorithms, but there are two results, API show Traditional, It’s not the QAT test result. ![](https://i.imgur.com/F53b3mx.png) API show Data_Plane, that is the QAT test result. ![](https://i.imgur.com/13Zb8rP.png) Default QAT sample code can be get result as following below item. * AES128-CBC HMAC-SHA1 * AES256-CBC HMAC-SHA2-512 * AES256-CBC AES-XCBC * AES128-CBC * AES256-CBC * KASUMI_F8 The following algorithm sample code results is QAT data (only one result ). * RSA CRT DECRYPT * DIFFIE-HELLMAN PHASE 2 * DSA VERIFY * ECDSA VERIFY ## Special thanks Bruce Li
