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.
