HybridPowerManagement_AppIdleMonitorOff

  • Article

Power management tests run on dGPU while analyzing Power-Management ETW events that are generated by DXGKrnl. For this test, an application is running on DGPU, but it is idle and nothing has been rendered for some time. The monitor is turned OFF. The test performs following validations:

  • Validation of Power components - the test validates that all required power components are declared by the driver.

  • Validation of latency - the driver reports latency (time for a component to transition to another F-state). The test checks that this number matches the actual latency.

  • Validate Active/Idle state of the component - checks that power components are in expected Active/Idle state (based on the test scenario).

  • Validate DState - checks that DGPU is in expected D state (based on the test scenario).

  • Validate DGPU process - checks which processes have devices on DGPU. Anything other than the test itself will result in failure.

Additional documentation

Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):

Running the test

Before you run the test, complete the test setup as described in the test requirements: WDTF System Fundamentals Testing Prerequisites.

Troubleshooting

For generic troubleshooting of HLK test failures, see Troubleshooting Windows HLK Test Failures.

For troubleshooting information, see Troubleshooting System Fundamentals Testing.

Error Description

Conformance issues

When the test detects a conformance issue, it saves an image in the test directory if the -saveBMP parameter is specified. You can view this image to help diagnose the issue.

Validation failures

To get more information about the failure, run the test under User Mode Debugger. The test will output the information that it gets from ETW events, to help diagnose the failure.

 

More information

Command syntax

Parameter Description

-saveBMP

By using this parameter, the test saves presented images in BMP format to the test directory in case of conformance failure. This is useful for diagnosing conformance failures.

-whql | -featurelevel:<fl>

-whql results in device creation with highest support on a given adapter. -featurelevel:<fl> creates a device of requested feature level

Default value: -wqhl for DX10+ drivers; -featurelevel:9.1 for DX9 drivers

-hybrid

This value forces application execution on dGPU as if it was on the DList.
