WDDM Unmap Segment to DummyPage Check
This automated test verifies that the AGP driver implements the guard page mappings for all AGP aperture segments properly.
The AGP driver implements the guard page mappings for all AGP aperture segments but IHV drivers have to implement the build paging buffer unmap segment to dummy page (DXGKARG_BUILDPAGINGBUFFER.UnmapApertureSegment.DummyPage) so that any corruption can be detected by dxgkrnl. Because on non-AGP systems we need IHV support the test has two modes, check the unmap segement to dummy page is supported and check for corruption.
