- Runtime Architectural Protocol as defined in the DXE CIS\r
+/** @file\r
+ This file implements Runtime Architectural Protocol as defined in the\r
+ Platform Initialization specification 1.0 VOLUME 2 DXE Core Interface.\r
\r
This code is used to produce the EFI runtime virtual switch over\r
\r
So here is the concept. The code in this module will never ever be called in\r
virtual mode. This is the code that collects the information needed to convert\r
to virtual mode (DXE core registers runtime stuff with this code). Since this\r
- code is used to fixup all runtime images, it CAN NOT fix it's self up. So some\r
+ code is used to fix up all runtime images, it CAN NOT fix it's self up. So some\r
code has to stay behind and that is us.\r
\r
Also you need to be careful about when you allocate memory, as once we are in\r
Runtime Arch Protocol definition no longer contains CalculateCrc32. Boot Service\r
Table now contains an item named CalculateCrc32.\r
