EFI_PHYSICAL_ADDRESS | MemoryStartAddress |
A zero-based value that indicates the ending bus that can access the memory region. A value of 0xFF for a PCI system indicates the region is accessible by all buses and is global in scope. An example of the EndBusNumber not being 0xFF is a system with two or more peer-to-host PCI bridges.
The type of memory region from the operating system's point of view. MemoryRegionType values are equivalent to the legacy INT 15 AX = E820 BIOS command values.
The size of the memory region in bytes.
EFI_PHYSICAL_ADDRESS EFI_MEMORY_SIZE_DATA::MemoryStartAddress |
The starting physical address of the memory region.
A zero-based value that indicates which processor(s) can access the memory region. A value of 0xFFFF indicates the region is accessible by all processors.
A zero-based value that indicates the starting bus that can access the memory region.
