| The complete dir tree is for testcases for resource management testing of linux kernel. |
| For the test plan please refer to the file testplan.txt |

| ***WARNING:*** |
| -------------- |
| The cpu controller test creates the cpu controller device as /dev/cpuctl. In |
| case you already have /dev/cpuctl it may be overwritten. So please rename it |
| to have a backup of your file. |
| |
| The cpuset controller also creates the device as /dev/cpuset, so please do the |
| similar work as above. |

| testplan.txt |
| ------------ |
| A brief description of the plan for resource management testing. |
| |
| test_controllers.sh |
| ------------------- |
| This is the main script file that starts the test. It first checks if the |
| controllers are enabled. If not enabled then it will not run the test and |
| will exit giving warning. |
| |
| README |
| ------ |
| This file. |
| |
| cgroup |
| ------ |
| Directory containing the cgroup regression testcases. |
| |
| cpuctl |
| ------ |
| Directory containing the cpu controller testcases. A similar directory will |
| be created for any new controller. |
| |
| memctl |
| ------ |
| Directory containing the memory controller testcases. A similar directory will |
| be created for any new controller. |
| |
| cpuset |
| ------ |
| Directory containing the cpuset controller testcases. A similar directory will |
| be created for any new controller. |
| |
| libcontrollers |
| -------------- |
| This directory contains the library for cpucontroller testing. |
| |
| Makefile |
| -------- |
| The usual Makefile to conduct all the tests. |
| |
| Before starting compilation this file checks if the kernel is supporting the |
| cpu controller. If yes it enters lower directory and compiles the source files |
| otherwise exits warning to user. |
| Hence the user has to take care of the fact that the test runs or just quiets. |
| (Your kernel needs to be 2.6.24 onwards with proper config options) |
| |
| And before starting test cpuset, Please check whether the test system has |
| 4 CPUs and 3 Memory nodes and the kernel version is 2.6.28 or above. |
| |
| A snapshot of config file options is given below: |
| CONFIG_CGROUPS=y |
| CONFIG_CGROUP_DEBUG=y |
| CONFIG_CGROUP_NS=y |
| CONFIG_CPUSETS=y |
| CONFIG_PROC_PID_CPUSET=y |
| CONFIG_GROUP_SCHED=y |
| CONFIG_FAIR_GROUP_SCHED=y |
| CONFIG_RT_GROUP_SCHED=y |
| # CONFIG_USER_SCHED is not set |
| CONFIG_CGROUP_SCHED=y |
