Typedefs
typedef struct __TEES_ContiguousMemoryHandle *	TEES_ContiguousMemoryHandle

Enumerations
enum	TEES_ContiguousAllocateFlags { TEES_CONTIGUOUS_FLAG_ZERO_ON_FREE = (1U << 0), TEES_CONTIGUOUS_FLAG_ZERO_ON_ALLOC = (1U << 1) }
	Determines the desired allocated memory handle properties. More...
enum	TEES_ContiguousMapFlags {   TEES_CONTIGUOUS_MAP_READ = (1U << 0), TEES_CONTIGUOUS_MAP_WRITE = (1U << 1), TEES_CONTIGUOUS_MAP_NON_CACHEABLE = (1U << 2), TEES_CONTIGUOUS_MAP_FIXED = (1U << 3),   TEES_CONTIGUOUS_MAP_POPULATE = (1U << 4) }
	Determines the desired mapping properties. More...

Functions
TEE_Result	TEES_AllocateContiguousMemory (const char *region, size_t size, size_t align, uint32_t flags, TEES_ContiguousMemoryHandle *memory)
	Allocates physically contiguous memory buffer handle of the specified region type. More...
void	TEES_ReleaseContiguousMemory (TEES_ContiguousMemoryHandle memory)
	Releases physically contiguous memory buffer that was previously allocated by TEES_AllocateContiguousMemory. More...
TEE_Result	TEES_MapContiguousMemory (TEES_ContiguousMemoryHandle memory, void **addr, uint32_t flags)
	Maps physically contiguous memory buffer previously allocated by TEES_AllocateContiguousMemory into the address space of current process. More...
void	TEES_UnmapContiguousMemory (void *addr)
	Unmaps physically contiguous memory buffer that was previously mapped by TEES_MapContiguousMemory. More...
TEE_Result	TEES_GetContiguousMemoryPhysaddr (TEES_ContiguousMemoryHandle memory, uint64_t *physaddr)
	Retrieves physical address of physically contiguous memory buffer that was previously allocated by TEES_AllocateContiguousMemory. More...
