Installing KAE

Install KAE on the physical machine and VM.

1. Download the KAE 2.0 source package.

   1	git clone https://gitee.com/kunpengcompute/KAE.git -b kae2

   

   If no device file is queried after the device is restarted and a driver is installed, a possible cause is that the OS has a built-in accelerator driver. You can unload the driver and then reload it. Alternatively, add the command for reloading the driver to the startup script re.local. The following uses hisi_sec2 as an example.

   rmmod hisi_sec2
   modprobe hisi_sec2

2. Install the kernel driver in the KAE source code directory.

   1 2	cd KAE sh build.sh driver

3. Check whether the drivers are installed.

   Check whether the accelerator engine file system exists in /sys/class/uacce.

   1	ll /sys/class/uacce/

   If the following information is displayed, the drivers have been installed:
