+resctrl_tests - resctrl file system test suit
+
+Authors:
+ Fenghua Yu <fenghua.yu@intel.com>
+ Sai Praneeth Prakhya <sai.praneeth.prakhya@intel.com>,
+ Arshiya Hayatkhan Pathan <arshiya.hayatkhan.pathan@intel.com>
+
+resctrl_tests tests various resctrl functionalities and interfaces including
+both software and hardware.
+
+Currently it supports Memory Bandwidth Monitoring test and Memory Bandwidth
+Allocation test on Intel RDT hardware. More tests will be added in the future.
+And the test suit can be extended to cover AMD QoS and ARM MPAM hardware
+as well.
+
+BUILD
+-----
+
+Run "make" to build executable file "resctrl_tests".
+
+RUN
+---
+
+To use resctrl_tests, root or sudoer privileges are required. This is because
+the test needs to mount resctrl file system and change contents in the file
+system.
+
+Executing the test without any parameter will run all supported tests:
+
+ sudo ./resctrl_tests
+
+OVERVIEW OF EXECUTION
+---------------------
+
+A test case has four stages:
+
+ - setup: mount resctrl file system, create group, setup schemata, move test
+ process pids to tasks, start benchmark.
+ - execute: let benchmark run
+ - verify: get resctrl data and verify the data with another source, e.g.
+ perf event.
+ - teardown: umount resctrl and clear temporary files.
+
+ARGUMENTS
+---------
+
+Parameter '-h' shows usage information.
+
+usage: resctrl_tests [-h] [-b benchmark_cmd [options]] [-t test list]
+ -b benchmark_cmd [options]: run specified benchmark
+ default benchmark is builtin fill_buf
+ -t test list: run tests specified in the test list, e.g. -t mbm,mba
+ -h: help
