This automated test verifies that drivers are stable when they perform bit-block transfers (bitblts) to and from system memory surfaces that have depth/stencil formats.
In particular, this test creates a video memory depth buffer of a supported format. It then creates a system memory lockable depth buffer and instructs the driver to perform a bitblt between them. The driver must not crash or hang during the test.
This topic applies to the following test jobs:
WDDM Blt - Depth
WDDM Blt - Depth (WoW64)
