Hybrid - Independent Driver Update (Discrete GPU)

The test uses the Microsoft Basic Render device as dGPU paired with IHV iGPU. A basic Hybrid Present test is run on this configuration to validate that it is still a valid Hybrid configuration and that Hybrid functionality is preserved.

ErrorDescription

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.

Cross Adapter Present 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.

Command syntax

ParameterDescription

-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.
