Hi, I have developed a testcase for CPU Accounting Controller which is
used to group tasks using cgroups and account the CPU usage of these groups of tasks.
Here I am posting the patch, please review the patch and let me know if
it needs any changes, thanks.

+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.

+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_task.c
+---------------
+This is the task which is run for eating up the cpu time.
+
+
+myfunctions.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 myfunctions.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.

Hi,
Few more comments below:
1) Checking your patch through linux*/scripts/checkpatch.pl:
ERROR: Missing Signed-off-by: line(s)
total: 48 errors, 89 warnings, 683 lines checked
Fix all the above errors/warnings,
2) Application of patch:
patching file testcases/kernel/controllers/cpuacct/cpuacct_task.c
patching file testcases/kernel/controllers/cpuacct/cpuacct_testplan.txt
patching file testcases/kernel/controllers/cpuacct/Makefile
patching file testcases/kernel/controllers/cpuacct/myfunctions.sh
patching file testcases/kernel/controllers/cpuacct/README
patching file testcases/kernel/controllers/cpuacct/run_cpuacct_test.sh
patching file testcases/kernel/controllers/Makefile
patching file testcases/kernel/controllers/README
patching file testcases/kernel/controllers/test_controllers.sh
patch: **** malformed patch at line 788: exit 0;
Fix the Patch itself for the malformed lines,
3) Running the tests:
<<<test_start>>>
tag=CPUACCT01 stime=1249970577
cmdline="$LTPROOT/testcases/bin/run_cpuacct_test.sh 1;"

newer

<<<test_start>>>

newer
<<<execution_status>>>
initiation_status="ok"
duration=0 termination_type=exited termination_id=0 corefile=no
cutime=0 cstime=1
<<<test_end>>>
Since you are not allowing these tests to run below 2.6.30 kernel, i
would request you to kindly share the results of test run on your
machine with the LTP list.
Regards--

+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.

+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_task.c
+---------------
+This is the task which is run for eating up the cpu time.
+
+
+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.

Hey,
Thanks for sending that update once again. But still issues remain to be
addressed:
1) # ls -l testcases/kernel/controllers/cpuacct/
total 72
-rwxr-xr-x 1 root root 4903 Aug 13 23:08 cpuacct_task
-rw-r--r-- 1 root root 121 Aug 13 23:05 cpuacct_task.c
-rw-r--r-- 1 root root 1665 Aug 13 23:05 cpuacct_testplan.txt
-rw-r--r-- 1 root root 377 Aug 13 23:05 Makefile
-rw-r--r-- 1 root root 1611 Aug 13 23:05 README
-rwxr-xr-x 2 root root 11213 Aug 13 23:08 run_cpuacct_test.sh
-rwxr-xr-x 2 root root 5075 Aug 13 23:05 setup.sh
You cannot have a generic file called "setup.sh" and then install it
over to "$LTPROOT/testcases/bin/". There are many tests which will try
to do the same and somebodyś "setup.sh" will be finally replaced by the
other at "$LTPROOT/testcases/bin/". So, replace this file name with
something more specific like "run_cpuacct_test_setup.sh", which is more
meaningful.
2) The test results are not encouraging though. You have tried to
directly run it from by (cd testcases/bin/) and then:
# ./run_cpuacct_test.sh 1
# ./run_cpuacct_test.sh 2
which is not correct. If you want to run just the CPUACCOUNTING
controllers without the need to run the entire controller tests through
test_controller.sh, then create a following file like:
# cat runtest/cpuacct
CPUACCT01 $LTPROOT/testcases/bin/run_cpuacct_test.sh 1
CPUACCT02 $LTPROOT/testcases/bin/run_cpuacct_test.sh 2
Then try with:
./runltp -f cpuacct
But i get the following output on my machine:
<<<test_start>>>
tag=CPUACCT01 stime=1250185313
cmdline="$LTPROOT/testcases/bin/run_cpuacct_test.sh 1"

What has gcc got to do during test run ??
Your makefile says that
"testcases/kernel/controllers/cpuacct/cpuacct_task" will get installed
at "testcases/bin/", but i do not find it after "make install", however
"run_cpuacct_test.sh" was present at "testcases/bin/". Though i manually
copied "testcases/kernel/controllers/cpuacct/cpuacct_task" to
"testcases/bin/", still i get the above output. Please fix this and
resend.

Duddu,
I'd reject this right away:
+case ${TEST_NUM} in
+ "1" )
+ gcc -o $PWD/cpuacct_task $PWD/cpuacct_task.c
+ ls $PWD/cpuacct_task &> /dev/null
+ if [ $? -ne 0 ]
+ then
+ echo "TFAIL Task file cpuacct_task.c not compiled"
+ echo "Please check Makefile Exiting test"
+ exit -1
+ fi
If your testcase can't live without gcc, then it needs to be
redesigned. I will do the Makefile work making things conform to a
proper standard, but I don't want to have to go hacking a bunch of
scripts if I can help it...
Thanks,
-Garrett

+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.

+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.

> +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.

> +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
