Failed to Identify Accelerators After KAE Is Installed

Symptom

After KAE is installed, the accelerators cannot be identified.

Key Process and Cause Analysis

None

Conclusion and Solution

  1. Check whether the devices exist in the virtual file system.
    1
    ls -al /sys/class/uacce/
    
    Normally, the following accelerators will be displayed:
    1
    2
    3
    total 0
    ../../devices/pci0000:74/0000:74:00.0/0000:75:00.0/uacce/hisi_zip-6
    lrwxrwxrwx. 1 root root 0 Nov 17 22:09 hisi_zip-7 -> ../../devices/pci0000:b4/0000:b4:00.0/0000:b5:00.0/uacce/hisi_zip-7
    
  2. If the zip device is not found in 1, check whether the KAE software is correctly installed by referring to KAE Initialization Failure.
  3. If the KAE software is correctly installed according to 2, run the lspci command to check whether the physical device exists.
    1. Check whether ZIP exists in the system.
      1
      lspci | grep ZIP
      
      Command output:
      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)
      
  4. If no physical device is found in 3, perform the following operations:
    • Check whether the accelerator license has been imported. If not, import the accelerator license. For details, see "License Management" in TaiShan Rack Server iBMC (V300 to V549) User Guide. After the accelerator license is imported, power off and restart the iBMC to enable the license.
    • Check whether the iBMC and BIOS versions support the accelerator feature.
