   3 # (http://www.intel.com/technology/framework/spec.htm) and data structures defind at IntelFrameworkPkg

   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.

  26   1. Guid/DataHubRecords.h
  27     #define EFI_STRING_TOKEN          UINT16
  28
  29     This macro named "EFI_STRING_TOKEN" is *NOT* defined in Framework specification. Keeping this inconsistency
  30     for backward compatibility.

  43
  44     Section "Alignment" in DataHubSubclass specification say "Fields in a data hub record should be aligned at their
  45     natural boundaries". But in EdkII, the data structures above are packed.
  46     Keeping this inconsistency for backward compatibility.

  49     #define EFI_SUBCLASS_INSTANCE_RESERVED       0
  50     #define EFI_SUBCLASS_INSTANCE_NON_APPLICABLE 0xFFFF
  51
  52     The symbols above are *NOT* defined in DataHubSubclass specification. But the values are defined and are meaningful.
  53     According to DataHubSubclass spec, value 0 means Reserved and -1 means Not Applicable. EdkII introduces these macros
  54     to faciliate user development.

  61
  62     The definition named "EFI_MAXIMUM_CACHE_SIZE_DATA" is *NOT* consistent with CacheSubclass specification, in which
  63     the name should be EFI_CACHE_MAXIMUM_SIZE_DATA. Keeping this inconsistency for backward compatibility.

  75
  76     The field type of the definition is *NOT* consistent with CacheSubclass specification. Specification defines

 613     a. The definitions above are *NOT* defined in MiscSubclass specifications 0.9. EdkII introduces them to simplify the
 614        code logic. Therefore developer doesn't need to allocate memory dynamically to construct variable length device
 615        path for various device.
 616        Keeping this inconsistency for backward compatibility.
 617
 618     b. The definitions above are packed. This way violates the rule of alignment defined in DataHubSubclass specification.
 619        Section "Alignment" in DataHubSubclass specification say "Fields in a data hub record should be aligned at their
 620        natural boundaries". Keeping this inconsistency for backward compatibility.

 628     The definition is *NOT* consistent with MiscSubclass specification, in which the type of last field is defined as

 696        From its literal sense, this field represents a AGP type display card, so it should be named as "EfiSlotTypeAgp2X".

1239     in which the type of this field is defined as UINTN. However, HOBs are supposed to be CPU neutral, so UINTN
1240     is incorrect and UINT32 should be used.
