Power Manager State Transition Tests (Compact 7)
3/12/2014
The Power Manager State Transition Tests verify the state transitions between different supported system power states. The tests include power state supported by both the DEFAULT and PDA power models.
Test Prerequisites
Your device must meet the following requirements before you run this test.
The following prerequisites are required for this test.
Hardware Prerequisites:
In order to run the test, the platform and/or device drivers should have power management capabilities.
Software Prerequisites:
Having the SYSGEN_PM sysgen variable set when building your OS image will include the Power Manager.
The following table shows the software requirements for this test.
| Requirement | Description |
|---|---|
Tux.exe |
Tux test harness that executes the test. |
Kato.dll |
Logging engine that logs test data. |
testutildrv.dll |
Utility driver to handle setting RTC wake source for suspend/resume |
pwrdrvr.dll |
Sample power managed device driver used during test |
pwrtsttransitions.dll |
Power Manager State Transition Test DLL. |
Subtests
The table below lists the subtests included in this test.
| SubTest ID | Description |
|---|---|
101 |
Test On state. This test will verify remaining in the On state when different events occur. This test is for images using the PDA power model only. |
102 |
Test transitions to and from BacklightOff state. This test will verify transitions to and from the BacklightOff state. This test is for images using the PDA power model only. |
103 |
Test transitions to and from UserIdle state. This test will verify transitions to and from the UserIdle state. This test is for images using the PDA power model only. |
104 |
Test transitions to and from ScreenOff state. This test will verify transitions to and from the ScreenOff state. This test is for images using the PDA power model only. |
201 |
Test On state. This test will verify remaining in the On state when different events occur. This test is for images using the DEFAULT power model only. |
202 |
Test transitions to and from UserIdle state. This test will verify transitions to and from the UserIdle state. This test is for images using the DEFAULT power model only. |
203 |
Test transitions to and from SystemIdle state. This test will verify transitions to and from the SystemIdle state. This test is for images using the DEFAULT power model only. |
204 |
Test transitions to and from Suspend state. This test will verify transitions to and from the Suspend state. This test is for images using the DEFAULT power model only. |
Setting Up the Test
This test has no additional requirements beyond the standard test environment setup.
Running the Test
The Power Manager State Transition Test executes the tux -o -d pwrtsttransitions.dll command line by default.
This test library can have one or more optional command line entries to change the behavior of the test. To specify one or more command line entries to the test library, you must use the -c command-line option. This option forces Tux to pass the specified string into the test library.
The following table shows the optional command line parameters for this test.
| Command Line Parameter | Description |
|---|---|
AllowSuspend |
Allows the tests to suspend the system. |
PdaVersion |
Informs the tests that this is a PDA-type device which tests a separate set of system power states. |
Verifying the Test
When the test completes running, verify that "PASS" appears in the test log for all sub-tests.
Troubleshooting the Test
* The platform must have power management capabilities.
* The platform must support the standard power states used in this test which target the DEFAULT and PDA versions of the Power Manager.
For additional platform specific issues, consult the CTK articles on the TechNet wiki.
