Obtaining a License

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

KAE on Kunpeng K series servers is enabled by default. You do not need to apply for a license.

1. For details about how to apply for and install a license, see Huawei Server iBMC License User Guide.
2. After installing a license, run the lspci command to check whether the OS has an accelerator device.
   

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

   1. Check whether the High Performance RSA Engine (HPRE) exists in the system.

      1	lspci | grep HPRE

      If the following information is displayed, HPRE exists in the system.

      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 whether the Security Engine (SEC) exists in the system.

      1	lspci | grep SEC

      If the following information is displayed, SEC exists in the system.

      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 whether the ZIP compression acceleration engine exists in the system.

      1	lspci | grep ZIP

      If the following information is displayed, the ZIP engine exists in the system.

      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.
