RETURN_STATUS EFIAPI PublishSystemMemory | ( | IN PHYSICAL_ADDRESS | MemoryBegin, | |
IN UINT64 | MemoryLength | |||
) |
Declares the presence of permanent system memory in the platform.
Declares that the system memory buffer specified by MemoryBegin and MemoryLength as permanent memory that may be used for general purpose use by software. The amount of memory available to software may be less than MemoryLength if published memory has alignment restrictions. If MemoryLength is 0, then ASSERT(). If MemoryLength is greater than (MAX_ADDRESS - MemoryBegin + 1), then ASSERT().
MemoryBegin | The start address of the memory being declared. | |
MemoryLength | The number of bytes of memory being declared. |
RETURN_SUCCESS | The memory buffer was published. | |
RETURN_OUT_OF_RESOURCES | There are not enough resources to publish the memory buffer |
