|
|
Arguments:
|
||
|
|
|
||
|
|
DebugDisposition - Supplies type information for the pointer being converted.
|

|
|
Returns:

|
|
EFI_NOT_FOUND - The pointer pointed to by Address was not found to be part
|
||
|
|
of the current memory map. This is normally fatal.
|
||
|
|
EFI_INVALID_PARAMETER - One of the parameters has an invalid value.

|
|
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
|
