WDDM Eviction
This automated test determines whether the video memory manager has performed eviction correctly.
There might be insufficient free video memory available to bring in all the resources that a Direct Memory Access (DMA) buffer requires. In this case, some resources that are currently in memory must be evicted.
The test creates a reference image. It then creates multiple images that have large resources, which makes sure that eviction will occur. The test compares each of these images with the reference image. If the video memory manager has performed eviction correctly, the two images should be identical.
