RPM Package Uninstallation (KAE 1.0)

This section describes how to uninstall KAE 1.0 that is installed using RPM packages if you no longer require it or want to install KAE of a new version. Due to the dependency relationships, the hisi_hpre and hisi_sec2 driver packages must be uninstalled before the UACCE driver package is uninstalled. The libkae engine package must be uninstalled before the libwd driver package is uninstalled.

Procedure

  1. Use an SSH tool to remotely log in to the Linux CLI as the root user.
  2. Uninstall the KAE software packages and check the uninstallation result.
    1. Uninstall the KAE software packages.
      Run the rpm -e Software_package_name command. For example, run the following command to uninstall hisi_zip.
      1
      rpm -e hisi_zip

      Due to the dependency relationships, you must uninstall the hisi_zip driver package before uninstalling the UACCE driver package, and uninstall the libkaezip engine package before uninstalling the libwd driver package.

    2. Check whether the uninstallation is successful.
      Run the rpm -qa |grep Software_package_name command. For example, run the following command to check whether hisi_zip is uninstalled:
      1
      rpm -qa |grep hisi_zip

      The following shows how to uninstall all KAE software packages:

  3. Restart the system or use commands to manually uninstall the accelerator drivers loaded to the kernel, and check whether the drivers are successfully uninstalled.
    1. Check drivers that have been loaded to the kernel.
      1
      lsmod | grep uacce
      Command output:
      1
       uacce                36864  3 hisi_qm,hisi_zip
    2. Uninstall the loaded drivers.
