Specifies the purpose of a page mapping range.

Syntax

typedef enum D3D12XBOX_PAGE_MAPPING_RANGE_TYPE
{
    D3D12XBOX_PAGE_MAPPING_RANGE_TYPE_INCREMENTING_PAGE_INDICES = 0,
    D3D12XBOX_PAGE_MAPPING_RANGE_TYPE_CONSTANT_PAGE_INDEX = 1,
    D3D12XBOX_PAGE_MAPPING_RANGE_TYPE_NULL_PAGES = 2,
    D3D12XBOX_PAGE_MAPPING_RANGE_TYPE_SKIP_RANGE = 3
} D3D12XBOX_PAGE_MAPPING_RANGE_TYPE;

Constants

Constant Description
D3D12XBOX_PAGE_MAPPING_RANGE_TYPE_INCREMENTING_PAGE_INDICES The source page indices are computed from the start page index and increment upwards. For example, if the StartPageIndexInPool is 5, and the PageCount is 3, then the source pages copied from the source page pool will be pages 5, 6, and 7.
D3D12XBOX_PAGE_MAPPING_RANGE_TYPE_CONSTANT_PAGE_INDEX The source page indices are a repetition of the same page index, specified by the start page index.
D3D12XBOX_PAGE_MAPPING_RANGE_TYPE_NULL_PAGES The destination page mappings in this range are set to null (invalid page mapping). No reference to the source page pool is made.
D3D12XBOX_PAGE_MAPPING_RANGE_TYPE_SKIP_RANGE The CopyPageMappingsX skips this range when constructing the source to destination page mapping copies, and does not increment the copy destination.

Remarks

This enum is used by the D3D12XBOX_PAGE_MAPPING_RANGE structure.
