-TEST SUITE:
-
-The directory cpuacct contains the tests related to cpu accounting controller.
-More testcases are expected to be added in future.
-
-TESTS AIM:
-
-The aim of the tests is to test cpu accounting controller functionality.
-
-FILES DESCRIPTION:
-
-cpuacct_task01.c
----------------
-This is the task which is run for eating up the cpu time.
-
-
-cpuacct_setup.sh
-----------
-This file contains the functions which are common for all the tests. For ex.
-the setup and cleanup functions which do the setup for running the test and do
-the cleanup once the test finishes. The setup() function creates /dev/cpuacct
-directory and mounts cgroup filesystem on it with accounting controller. It
-then creates a number(n) of groups in /dev/cpuacct. The cleanup function does a
-complete cleanup of the system.
-
-Most of the error scenarios have been taken care of for a sane cleanup of the
-system. However if cleanup fails in any case, just manually execute the
-commands written in cleanup function in setup.sh.
-One of the most common causes of failed cleanup is that you have done cd into
-any of the groups in controller dir tree.
-
-run_cpuacct_test.sh
-------------------
-This script creates different scenarios for cpu accounting controller testing and
-starting (n) tasks in different groups to do some cpu allocations etc. It
-checks for the cpu usage of the groups and reports test pass/fail accordingly.
-
-Makefile
---------
-
-The usual makefile for this directory
-
-PASS/FAIL CRITERION:
-==================
-The test cases are intelligent enough in deciding the pass or failure of a
-test.
-
-README:
---------
-The one you have gone through.

-The CPU Accounting controller testplan includes a complete set of
-testcases that test the CPU Accounting controller in different scenarios.
-
-
-TESTCASE DESCRIPTION:
-====================
-
-These tests will check if the cpu usage of the child cgroup is
-getting reflected in the parent cgroup.Reports PASS if the cpu
-usage is same for both the cgroups and FAIL if they differ.
-
-In these tests cpu usage of the tasks running in a group is read in
-terms of 3 different stat values.
-
-'cpuacct.usage' gives the current cpu usage of the task running
-in the group.
-'cpuacct.usage_percpu' gives the cpu usage of each cpu.
-'cpuacct.stat' gives the user and system cpu usage of the task running
-in the group.
-
-Test01: STAT CHECK TEST
--------------------------------
-This test is run by running a task in the child group and reading it's stat
-values and comparing them with the parent group's stat values.
-
-Test02: STAT CHECK TEST
--------------------------------
-This test is run by running num_online_cpus number of tasks in 2 child groups,
-adding the stat values from the child groups and comparing them with the
-parent's stat values.
-
-The values reported for user and system time in cpuacct.stat is not very
-accurate and they can vary from the actual values by Threshold*num_online_cpus in the
-worst case.
-Where Threshold T = max(num_online_cpus^2, 32)
-
-In this test case, we allow for a max difference between actual and reported
-values to be 2T. If the difference between parent's value and children's value
-is greater than 2T, we mark the test as failed.
-
-
-For any other information please refer to
-Documentation/controllers/cpuacct.txt in kernel documentation.
