DXGI HybridPresent

Article
02/27/2017

This test runs on Microsoft Supported Graphics Hybrid Configurations as if it is on the DList. The test runs a simple present scenario (present a frame) and does following validations:

Conformance of the displayed image
Validation of CrossAdapter surfaces (unless Vista BLT presentation model)
Validation of Presents (CrossAdapter present versus Regular present)

The test iterates on the following:

Presentation models – Blt, Flip, DirectFlip
Fullscreen vs. Windowed
Swapchain surface format

Type	Automated

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 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.
Cross Adapter surface validation or 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

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.
