POWER MANAGEMENT TESTS AUTOMATION SUITE
----------------------------------------
The tests requires the Kernel to  be compiled with the following config's

for CPU FREQUENCY tests:
 
CONFIG_CPU_FREQ
CONFIG_CPU_FREQ_TABLE
CONFIG_CPU_FREQ_DEBUG
CONFIG_CPU_FREQ_STAT
CONFIG_CPU_FREQ_STAT_DETAILS
CONFIG_CPU_FREQ_DEFAULT_GOV_*
CONFIG_CPU_FREQ_GOV_*

for CPU IDLE tests:

CONFIG_CPU_IDLE
CONFIG_CPU_IDLE_GOV_LADDER
CONFIG_CPU_IDLE_GOV_MENU

for SCHED_MC tests:

CONFIG_SCHED_MC

The power management test automation suite helps run the power management functionality
(e.g: cpu frequency, cpu idle etc..) tests and report results. 

Test Scripts for CPU FREQUENCY:
change_freq.sh
change_govr.sh
check_cpufreq_sysfs_files.sh

Test Scripts for CPU IDLE:
will be added soon

Test Scripts for SCHED_MC:
test_sched_mc.sh

Common functionality:
pm_include.sh
check_kv_arch.c 
pwkm_load_unload.sh

To run your tests you can execute the runpwtests.sh

To run the tests individually :

P.S. As of now the supporting architecture(s) are x86,x86_64

Support of system:
-----------------
If you see some thing like following,

Power Management    1  FAIL  :  Required kernel configuration for SCHED_MC NOT set
or
Power Management    1  FAIL  :  Required kernel configuration for CPU_FREQ NOT set

Then either configuration is not set or the system won't support.
