Compiling and Installing the KSAL zstd Algorithm Package

Procedure

1. Create a directory and go to the directory.

   1 2	mkdir /home/ksal_zstd cd /home/ksal_zstd

2. Obtain BoostKit-boostsds-ksal-1.11.0.zip and save it to the /home/ksal_zstd directory.
3. Decompress BoostKit-boostsds-ksal-1.11.0.zip in the /home/ksal_zstd directory.

   1	unzip BoostKit-boostsds-ksal-1.11.0.zip

4. Download zstd-1.5.6.tar.gz and save it to the /home/ksal_zstd directory.
5. Click here to obtain the files required for compilation, including Makefile, ksal-zstd.patch, ksal_zstd.spec, and libksal_zstd_so_create.sh, and save them to the /home/ksal_zstd directory.
6. Generate the RPM installation package of the KSAL zstd compression algorithm.
   1. Install rpmbuild.

      1 2	yum install rpmdevtools -y rpmdev-setuptree

   2. Move the rpmbuild directory to the /home/ksal_zstd directory.
      1. After running the rpmbuild installation command, modify the .rpmmacros file. Change %_topdir to /home/ksal_zstd/rpmbuild, as shown in the following figure.

         1	vi /root/.rpmmacros

         

      2. Run the rpmbuild installation command again.

         1	rpmdev-setuptree

   3. Build an RPM package.

      Run the following command in the /home/ksal_zstd directory to generate the RPM package for KSAL zstd installation and deployment:

      1	sh libksal_zstd_so_create.sh

      The generated RPM package is stored in /home/ksal_zstd/rpmbuild/RPMS/aarch64/.

7. Install the generated RPM package.

   1 2	cd /home/ksal_zstd/rpmbuild/RPMS/aarch64 rpm -ivh boostsds-libksal-release-1.11.0.oe2203.aarch64.rpm

8. Run the following command to check the RPM installation status:

   1	rpm -qi boostsds-libksal-1.11.0-oe2203.aarch64

   Information similar to the following is displayed:

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

   Name : boostsds-libksal Version : 1.11.0 Release : oe2203 Architecture: aarch64 Install Date: Mon 16 Dec 2024 03:50:00 PM CST Group : Unspecified Size : 1378916 License : GPL Signature : (none) Source RPM : boostsds-libksal-1.11.0-oe2203.src.rpm Build Date : Thu 18 Dec 2025 02:50:00 PM CST Build Host : buildhost Summary : Kunpeng Storage Acceleration Library Description : Kunpeng Storage Acceleration Library Product Name: Kunpeng BoostKit Product Version: 25.2.T7 Component Name: BoostKit-KSAL Component Version: 1.11.0 Component AppendInfo: kunpeng
9. Confirm the installation path.

   Run the following command to view the file list in the /usr/ksal_zstd/ directory and check whether the KSAL zstd dynamic library file and KSAL zstd header file are stored in this directory:

   1	ll /usr/ksal_zstd

   

10. After the KSAL zstd algorithm package is installed:
    • To enable the KSAL zstd algorithm in Ceph, deploy a Ceph cluster and enable the algorithm using the ceph-ksal-zstd-plugin.patch file.
    • To directly invoke KSAL to optimize system performance, you can skip Compiling and Deploying Ceph and refer to KSAL Development Reference.
