Module Name:
Crc32.c
Abstract:
CalculateCrc32 Boot Services as defined in DXE CIS.
This Boot Services is in the Runtime Driver because this service is
also required by SetVirtualAddressMap() when the EFI System Table and
EFI Runtime Services Table are converted from physical address to
virtual addresses. This requires that the 32-bit CRC be recomputed.

Module Name:
Runtime.c
Abstract:
Runtime Architectural Protocol as defined in the DXE CIS
This code is used to produce the EFI runtime virtual switch over
THIS IS VERY DANGEROUS CODE BE VERY CAREFUL IF YOU CHANGE IT
The transition for calling EFI Runtime functions in physical mode to calling
them in virtual mode is very very complex. Every pointer in needs to be
converted from physical mode to virtual mode. Be very careful walking linked
lists! Then to make it really hard the code it's self needs be relocated into
the new virtual address space.
So here is the concept. The code in this module will never ever be called in
virtual mode. This is the code that collects the information needed to convert
to virtual mode (DXE core registers runtime stuff with this code). Since this
code is used to fixup all runtime images, it CAN NOT fix it's self up. So some
code has to stay behind and that is us.
Also you need to be careful about when you allocate memory, as once we are in
runtime (including our EVT_SIGNAL_EXIT_BOOT_SERVICES event) you can no longer
allocate memory.
Any runtime driver that gets loaded before us will not be callable in virtual
mode. This is due to the fact that the DXE core can not register the info
needed with us. This is good, since it keeps the code in this file from
getting registered.
Revision History:
- Move the CalculateCrc32 function from Runtime Arch Protocol to Boot Service.
Runtime Arch Protocol definition no longer contains CalculateCrc32. Boot Service
Table now contains an item named CalculateCrc32.

Routine Description:
When a SetVirtualAddressMap() is performed all the runtime images loaded by
DXE must be fixed up with the new virtual address map. To facilitate this the
Runtime Architectural Protocol needs to be informed of every runtime driver
that is registered. All the runtime images loaded by DXE should be registered
with this service by the DXE Core when ExitBootServices() is called. The
images that are registered with this service must have successfully been
loaded into memory with the Boot Service LoadImage(). As a result, no
parameter checking needs to be performed.
Arguments:
This - The EFI_RUNTIME_ARCH_PROTOCOL instance.
ImageBase - Start of image that has been loaded in memory. It is either
a pointer to the DOS or PE header of the image.
ImageSize - Size of the image in bytes.
RelocationData - Information about the fixups that were performed on ImageBase
when it was loaded into memory. This information is needed
when the virtual mode fix-ups are reapplied so that data that
has been programmatically updated will not be fixed up. If
code updates a global variable the code is responsible for
fixing up the variable for virtual mode.
Returns:
EFI_SUCCESS - The ImageBase has been registered.

Routine Description:
This function is used to support the required runtime events. Currently only
runtime events of type EFI_EVENT_SIGNAL_VIRTUAL_ADDRESS_CHANGE needs to be
registered with this service. All the runtime events that exist in the DXE
Core should be registered with this service when ExitBootServices() is called.
All the events that are registered with this service must have been created
with the Boot Service CreateEvent(). As a result, no parameter checking needs
to be performed.
Arguments:
This - The EFI_RUNTIME_ARCH_PROTOCOL instance.
Type - The same as Type passed into CreateEvent().
NotifyTpl - The same as NotifyTpl passed into CreateEvent().
NotifyFunction - The same as NotifyFunction passed into CreateEvent().
NotifyContext - The same as NotifyContext passed into CreateEvent().
Event - The EFI_EVENT returned by CreateEvent(). Event must be in
runtime memory.
Returns:
EFI_SUCCESS - The Event has been registered.
