1## 2# This file is used to document mismatches between Intel Platform Innovation Framework specification 3# (http://www.intel.com/technology/framework/spec.htm) and data structures defind at IntelFrameworkPkg 4# package in EdkII Open Source Project (https://edk2.tianocore.org/source/browse/edk2/trunk/edk2/IntelFrameworkPkg) 5## 6 7## 8# The general consideration about keeping the mismatches in EdkII: 9# 1. Some definitions defined in Framework specification may bring a little complexity on implementation. EdkII 10# makes changes on them from the view of code development. 11# 2. Some definitions are NOT defined in Framework specification, but introduced in Edk. EdkII chooses to keep 12# them for backward-compatibility. 13# 3. The name of some definitions are NOT consistent with Framework specification. If the name doesn't bring 14# misunderstanding literally, EdkII chooses to keep them for backward-compatibility. 15# 4. Some defintitions don't exactly match Framework specification, some new field members are introduced in EdkII 16# to reflect the latest industry standard. 17# 18# Note: 19# The IntelFrameworkPkg contains Framework specification contents that were not adopted by UEFI/PI, and names may be 20# changed (such as adding "FRAMEWORK_") to avoid name collisions with approved UEFI/PI specifications. 21## 22 23## 24# Mismatch with Intel Platform Innovation Framework for DataHubSubclass Specification (Version 0.90) 25## 26 1.
