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.

The EFI_SECURITY_ARCH_PROTOCOL (SAP) is used to abstract platform-specific
policy from the DXE core response to an attempt to use a file that returns a
given status for the authentication check from the section extraction protocol.
The possible responses in a given SAP implementation may include locking
flash upon failure to authenticate, attestation logging for all signed drivers,
and other exception operations. The File parameter allows for possible logging
within the SAP of the driver.
If File is NULL, then EFI_INVALID_PARAMETER is returned.
If the file specified by File with an authentication status specified by
AuthenticationStatus is safe for the DXE Core to use, then EFI_SUCCESS is returned.
If the file specified by File with an authentication status specified by
AuthenticationStatus is not safe for the DXE Core to use under any circumstances,
then EFI_ACCESS_DENIED is returned.
If the file specified by File with an authentication status specified by
AuthenticationStatus is not safe for the DXE Core to use right now, but it
might be possible to use it at a future time, then EFI_SECURITY_VIOLATION is
returned.
@param This The EFI_SECURITY_ARCH_PROTOCOL instance.
@param AuthenticationStatus
This is the authentication type returned from the Section
Extraction protocol. See the Section Extraction Protocol
Specification for details on this type.
@param File This is a pointer to the device path of the file that is
being dispatched. This will optionally be used for logging.
@retval EFI_SUCCESS The file specified by File did authenticate, and the
platform policy dictates that the DXE Core may use File.
@retval EFI_INVALID_PARAMETER Driver is NULL.
@retval EFI_SECURITY_VIOLATION The file specified by File did not authenticate, and
the platform policy dictates that File should be placed
in the untrusted state. A file may be promoted from
the untrusted to the trusted state at a future time
with a call to the Trust() DXE Service.
@retval EFI_ACCESS_DENIED The file specified by File did not authenticate, and
the platform policy dictates that File should not be
used for any purpose.
