Obtaining a License

Before the installation, ensure that the environment meets the hardware and software requirements of KAE and a license has been correctly installed. The OS can detect the accelerator devices only after the license is successfully installed.

• KAE is enabled by default on Kunpeng K series servers. You do not need to apply for a license.
• The new Kunpeng 920 processor model can use KAE without a license after the BIOS is upgraded to 21.23 or later.

1. Apply for and install a license. For details, see Huawei Server iBMC License User Guide.
2. Run the lspci command to check whether the OS has an accelerator device.
   

   The accelerator description returned by the lspci command varies depending on the OS. In addition to filtering by keywords, you can also check whether the following accelerator SBDF information exists.

   1. Check for the High Performance RSA Engine (HPRE).

      1	lspci | grep HPRE

      If information similar to the following is displayed, the HPRE exists in the OS.

      1 2	79:00.0 Network and computing encryption device: Huawei Technologies Co., Ltd. HiSilicon HPRE Engine (rev 21) b9:00.0 Network and computing encryption device: Huawei Technologies Co., Ltd. HiSilicon HPRE Engine (rev 21)

   2. Check for the Security Engine (SEC).

      1	lspci | grep SEC

      If information similar to the following is displayed, the SEC exists in the OS.

      1 2	76:00.0 Network and computing encryption device: Huawei Technologies Co., Ltd. HiSilicon SEC Engine (rev 21) b6:00.0 Network and computing encryption device: Huawei Technologies Co., Ltd. HiSilicon SEC Engine (rev 21)

   3. Check for the ZIP compression acceleration engine.

      1	lspci | grep ZIP

      If information similar to the following is displayed, the ZIP engine exists in the OS.

      1 2	75:00.0 Processing accelerators: Huawei Technologies Co., Ltd. HiSilicon ZIP Engine (rev 21) b5:00.0 Processing accelerators: Huawei Technologies Co., Ltd. HiSilicon ZIP Engine (rev 21)

   If no command output is displayed, no KAE accelerator device exists in the OS. Check whether the license is successfully installed.
