+# DSA(Data Streaming Accelerator) Test Cases
+
+## Description
+```
+Intel DSA is a high-performance data copy and transformation accelerator that
+will be integrated in SPR, targeted for optimizing streaming data movement and
+transformation operations common with applications for high-performance storage,
+networking, persistent memory, and various data processing applications. IAA is
+a similar accelerator which is more focused on data encryption and decryption.
+DSA and IAA share the same Linux Kernel driver “IDXD”
+```
+
+## Usage
+```
+IDXD is the DSA driver name and enabled after kernel 5.19, it is better to do tests
+newer than that.
+
+./dsa_user.sh -t check_dsa_driver
+IDXD driver is for both dsa and iaa, check if the driver is loaded.
+./dsa_user.sh -t check_dsa0_device
+After the driver is loaded, devices are enabled under /sys/bus/dsa/devices.
+./dsa_user.sh -t check_shared_mode
+If SVM(Shared Virtual Memory) is supported, the pasid_enabled is 1. If it is 0,
+the shared mode is not confgurable.
+```
+
+## Expected result
+```
+All test results should show pass, no fail.
+```
+
+## accel-config
+```
+accel-config - configure and control DSA(data streaminng accelerator) subsystem
+devices. The git repo is https://github.com/intel/idxd-config.git. 
+accel-config -h and accel-config --list-cmds introduce how to use the tool.
+```
