Routine Description:

Arguments:
|
|
|
|
DebugDisposition - Supplies type information for the pointer being converted.
|
|
ConvertAddress - A pointer to a pointer that is to be fixed to be the value needed
|
|
for the new virtual address mappings being applied.
|
|
|
|
Returns:
|
|
|
|
EFI_SUCCESS - The pointer pointed to by Address was modified.
|
|
EFI_NOT_FOUND - The pointer pointed to by Address was not found to be part
|
|
of the current memory map. This is normally fatal.

Routine Description:
|
|
|
|
Changes the runtime addressing mode of EFI firmware from physical to virtual.
|
|
|
|
Arguments:
|
|
|
|
MemoryMapSize - The size in bytes of VirtualMap.
|
|
DescriptorSize - The size in bytes of an entry in the VirtualMap.
|
|
DescriptorVersion - The version of the structure entries in VirtualMap.
|
|
VirtualMap - An array of memory descriptors which contain new virtual
|
|
address mapping information for all runtime ranges.
|
|
|
|
Returns:
|
|
|
|
EFI_SUCCESS - The virtual address map has been applied.
|
|
EFI_UNSUPPORTED - EFI firmware is not at runtime, or the EFI firmware is already in
|
|
virtual address mapped mode.
|
|
EFI_INVALID_PARAMETER - DescriptorSize or DescriptorVersion is invalid.
|
|
EFI_NO_MAPPING - A virtual address was not supplied for a range in the memory
|
|
map that requires a mapping.
|
|
EFI_NOT_FOUND - A virtual address was supplied for an address that is not found
|
|
in the memory map.
