XGMemoryLayout Members

XGMemoryLayout has the following members.

Public Methods

	Name	Description
	CopyMapping	Copies a source mapping into a destination mapping, with the optional ability to replace ESRAM page mappings in the source mapping with newly allocated system memory pages in the destination mapping.
	CreateMapping	Creates a new mapping with the given name.
	EnsureMappingSize	Checks whether the layout has virtual address space remaining for a mapping of the given size in pages.
	GetBaseAddress	Returns the base GPU virtual address of this layout, as a void pointer.
	GetCurrentAddress	Returns the current virtual address of this layout as it is being constructed, as a void pointer.
	GetCurrentPageOffset	Returns the current page offset of this layout as it is being constructed.
	GetEsramPageRanges	Returns a set of page ranges within the mapping that are mapped to ESRAM pages.
	GetFreeEsramPageCount	Returns the number of free ESRAM pages remaining.
	GetFreeSystemPageCount	Returns the number of free system memory pages remaining.
	GetGpuBaseAddress	Returns the base GPU virtual address of this layout, as a XG_GPU_VIRTUAL_ADDRESS (a UINT64).
	GetGpuCurrentAddress	Returns the current virtual address of this layout as it is being constructed, as a XG_GPU_VIRTUAL_ADDRESS (a UINT64).
	GetMaxUsedEsramPageCount	Returns the max number of ESRAM pages in use at the same time in this layout.
	GetMaxUsedSystemPageCount	Returns the maximum number of system memory pages in use at the same time in this layout.
	GetPageCount	Returns the number of pages in the layout.
	GetPageCountRemaining	Returns the number of unmapped pages remaining in this layout.
	GetPageSizeBytes	Returns the size of one page in this layout, in bytes.
	IsValid	Returns true if the current layout is valid.
	MapFromPattern	Maps pages using a predefined pattern passed as a byte array.
	MapPagePriorityArray	Maps pages using a page priority array.
	MapRunLengthArray	Maps pages using a run length array of tokens.
	MapSimple	Maps pages using a simple arrangement of ESRAM pages followed by system memory pages.
	RelinquishMapping	Relinquishes a previously defined mapping, placing its ESRAM and system pages back on the free lists.
	Reset	Resets the layout; decommits all pages from the virtual address range, returns all ESRAM and system memory pages to the free lists, and invalidates all mappings made upon this layout.
