Appendix A EDK II File Templates
This discussion contains templates and guidelines for creating files for protocols, GUIDs, EDK II Library Classes, and UEFI drivers in EDK II packages. The naming conventions for the driver entry point and the functions exported by a driver that are presented here guarantee that a unique name is produced for every function, which aides in call stack analysis when root-causing driver issues. The Doxygen style function header comment blocks have been removed the file templates shown in this appendix to highlight the source code elements required to build a UEFI Driver. The function headers comments blocks can be added by coping them from the EDK II MdePkg protocol include files located in the MdePkg/Include/Protocol/ directory.
The following expressions are used throughout this chapter to show where protocol names, GUID names, function names, and driver names should be substituted in a file template:
<<PackageName>>Represents the name of a package follows the function or variable naming convention, which capitalizes only the first letter of each word (e.g.,
MdePkg).<<BriefDescription>>One line brief description of a file or library or module.
<<DetailedDescription>>Paragraph that is a detailed description of a file or library or module.
<<Copyright>>One or more copyright declarations for a file or library or module.
<<License>>One or more licenses for a file or library or module.
<<ProtocolName>>Represents the name of a protocol that follows the function or variable naming convention, which capitalizes only the first letter of each word (e.g.,
DiskIo).<<PROTOCOL_NAME>>Represents the name of a protocol that follows the data structure naming convention, which capitalizes all the letters and separates each word with an underscore '_' (e.g.,
DISK_IO).<<GUID_STRUCT>>Represents the GUID value in the format of a C data structure. New GUID values can be generated using the
GUIDGEN utility shipped with Microsoft* compilers, or the uuidgen command under Linux - e.g. { 0x9e34954, 0x6c5, 0x4e1a, { 0xb7,0xeb, 0x5d, 0x5c, 0x9, 0xca, 0x6d, 0xaf } }.<<GUID_REGISTRY_FORMAT>>Represents the GUID value in Registry Format. New GUID values can be generated
using the
GUIDGEN utility shipped with Microsoft* compilers, or the uuidgen command under Linux. (e.g., 1E9CD853-7A32-49e0-8140-145CD35C6632)<<DriverVersion>>A 32-bit value representation for the version of the UEFI Driver used to fill in the
Version field of the Driver Binding Protocol. (e.g., 0x00000010).<<DriverVersionString>>A text string representation for the version of the UEFI Driver. (e.g., 1.7).
<<FunctionNameN>>Represents the nth name of the protocol member functions that follow the function or variable naming convention, which capitalizes only the first letter of each word (e.g.,
ReadDisk).<<FUNCTION_NAMEn>>Represents the nth name of the protocol member functions that follows the data structure naming convention, which capitalizes all the letters and separates each word with an underscore '_' (e.g.,
READ_DISK).<<GuidName>>Represents the name of a GUID that follows the function or variable naming convention, which capitalizes only the first letter of each word (e.g.,
GlobalVariable).<<GUID_NAME>>Represents the name of a GUID that follows the data structure naming convention, which capitalizes all the letters and separates each word with an underscore '_' (e.g.,
GLOBAL_VARIABLE).<<DriverName>>Represents the name of a driver that follows the function or variable naming convention, which capitalizes only the first letter of each word (e.g.,
Ps2Keyboard).<<DRIVER_NAME>>Represents the name of a driver that follows the data structure naming convention, which capitalizes all the letters and separates each word with an underscore '_' (e.g.,
PS2_KEYBOARD).<<DriverVersion>>Value that represents the version of the driver. Values from 0x0-0x0f and 0xFFFFFFF0-0xFFFFFFFF are reserved for UEFI drivers that are written by OEMs for integrated devices. Values from 0x10-0xFFFFFFEF are reserved for UEFI drivers that are written by IHVs.
<<Iso639SupportedLanguages>>A null terminated ASCII string of one or more 3 character ISO 639-2 language code with no separator character. (e.g. "eng" for English, "engfra" for English and French).
<<Rfc4646SupportedLanguages>>A null terminated ASCII string of one or more RFC 4646 language codes separated by semicolons (';') (e.g. "en" for English, "en-US;fr" for U.S. English and French).
<<UEFI_SYSTEM_TABLE_REVISON>>The 32-bit revision of the UEFI Specification that the UEFI Driver requires to run correctly. Usually, one of the define names from
<Uefi.h> is used, which includes the following:1
EFI_2_31_SYSTEM_TABLE_REVISION
2

EFI_2_30_SYSTEM_TABLE_REVISION

<<ProtocolNameCn>>Represents the nth name of a protocol that is consumed by a UEFI driver and follows the function or variable naming convention, which capitalizes only the first letter of each word (e.g.,
DiskIo).<<PROTOCOL_NAME_CN>>Represents the nth name of a protocol that is consumed by a UEFI driver and follows the data structure naming convention, which capitalizes all the letters and separates each word with an underscore '_' (e.g.,
DISK_IO).<<ProtocolNamePm>>Represents the mth name of a protocol produced by a UEFI driver that follows the function or variable naming convention which capitalizes only the first letter of each word (e.g.,
DiskIo).<<PROTOCOL_NAME_PM>>Represents the mth name of a protocol that is produced by a UEFI driver and follows the data structure naming convention, which capitalizes all the letters and separates each word with an underscore '_' (e.g.,
DISK_IO).<<UsbSpecificationMajorRevision>>Denotes the major revision of the USB Specification that a USB host controller driver follows (e.g. 1 for the USB 1.1 Specification).
<<UsbSpecificationMinorRevision>>Denotes the minor revision of that USB Specification that a USB host controller driver follows (e.g. 0 for the USB 2.0 Specification).
