https://edk2.tianocore.org/svn/edk2/trunk/edk2
-----------------------
Notes On Documentation
-----------------------
The documents are being managed by the Subversion Source Control on
Tianocore.org. The document repository is "docs" and must be checked out
separately from the EDK 2.0 source tree. Refer to the checkout procedures on
the Tianocore.org website for EDK 2.0.

-----------------------
Notes On Required Tools (MS Windows environment example)
-----------------------
Software Installation Order:
After installing the compiler tools and your Subversion client, the following
required tools should be installed in order:
Java JDK, Apache-Ant, ant-contrib, xmlbeans, saxon8
Java Development Kit:
The Java Environment Variable must be set before attempting to build.
i.e. For Sun JDK (see note below*):
set JAVA_HOME=c:\ Java\jdk1.5.0_06
i.e. For Bea Systems:
set JAVA_HOME=c:\Program Files\Java\jrockit-R26.0.0-jdk1.5.0_04
*When using the Sun JDK5.0
During installation, you should specify the install directory as C:\Java
instead of C:\Program Files\(or some other drive letter.) While installing
to this non-standard location is not required. In use, it seems to work
more reliably.
For the JDK, the install path would be C:\Java\jdk1.5.0_06
For the JRE, the install path would be C:\Java\jre1.5.0_06
Alternatively, you can specify C:\sunjavajdk and C:\sunjavajre.
NOTE: You cannot combine the location for the JDK and the JRE, as the JRE
install removes most of the binaries and libraries installed by the JDK
install.
Java Tools:
The Apache-ANT requires the ANT_HOME environment variable to be set before
attempting to build:
i.e. set ANT_HOME=c:\ant
The ant-contrib.jar file should be installed in the %ANT_HOME%\lib
directory.
The XMLBeans, requires the XMLBEANS_HOME environment variable to be set
before attempting to build:
i.e. set XMLBEANS_HOME=C:\XMLBEANS
The saxon8.jar file should be copied to the %XMLBEANS_HOME%\lib directory.
The Ant and XMLBean tools are required to be in the path.
MS system example:
set PATH=%PATH%;%ANT_HOME%\bin;%XMLBEANS_HOME%\bin
Linux/OS X bash shell example:
export PATH=$PATH:${ANT_HOME}/bin:${XMLBEANS_HOME}/bin
-------------------------------------------------------------------------------
Quick Start
-----------
Edit the text file, tools_def.txt, located in the Tools/Conf directory. This
file contains the names of the compiler tool chains and the location of the
compiler binaries. It has been pre-populated with the standard location for
the Microsoft tool chains and includes the standard location of the Intel C
Compiler for EFI Byte Code (EBC)
Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to
checkout the entire EDK 2.0 source tree.
In a command window, change to the top level directory of the Edk 2.0 sources.
Set the WORKSPACE environment variable, e.g.:
c:\> set WORKSPACE=C:\MyWork\Edk2.0
To test your tool chain setup and to build the Supplied Tools, execute:
c:\MyWork\Edk2.0\> edksetup
(This command will be referred to as the setup command throughout the rest of
this document.)
NOTE: You should run the setup command at the start of every session.
This configures the environment to include the TianoTools and the
Java applications and libraries.
Once this is completed, you are ready to test the Build, by executing:
c:\MyWork\Edk2.0\> ant
This command builds all of the packages, including the NT32 reference platform.
-------------------------
Individual Package Builds
-------------------------
After running the setup command, you can build individual packages.
In the command window, cd to the package that you want to build, and just
type:
c:\MyWork\Edk2.0\EdkNt32Pkg\> ant
The EdkNt32Pkg has a special target; "run" that will execute the Nt32 emulation
platform under Microsoft Windows.
------------------------
Individual Module Builds
------------------------
After running the setup command, you can build individual modules.
In the command window, cd to the module that you want to build, and just
type:
c:\MyWork\Edk2.0\MdePkg\Library\BaseLib\> ant
-------------------------------------------------------------------------------
A Word on Apache-ANT
--------------------
The Apache-ANT program is a build tool that uses XML-based project files.
Similar to Makefiles, these project files may contain multiple targets. Most
build.xml files in Edk2.0 are auto-generated; any edits performed on the
build.xml files will be overwritten the next time ant is executed.
Pre-defined targets in the build.xml files include:
all - This target builds binaries for defined architectures
clean - This target removes object files generated by commands
cleanall - This target removes all generated files and directories.
A Word on GCC tool chain
------------------------
You will find a script in the tree that will download, configure, compile, and
install a gcc 4.0.2 tool chain for development. It has support for the ia32
architecture. It can be built and run on Cygwin, Linux, and many other POSIX
compliant host environments. There are a few tools that you will need on your
host computer in order to compile the tool chain. Among them are bash, gcc,
gmake, curl (or wget).
-------------------------------------------------------------------------------
General Information:
===============================================================
Mechanisms:
----------
A quick understanding:
A) Surface Area Package Description (SPD) file contains information about the
modules that the package contains, including the location of all MSA files, and
public library names and headers that might be provided by a module in the
package. Packages are defined by SPD files. (Found in the root of the Package
subdirectory (i.e. EdkNt32Pkg)) The SPD is further explained in the "Build
Packaging Specification" document.
B) Module Surface Area Definition (MSA) files. A description of a module's
surface area, with all module specific default flags and features specified.
Refer to the "Module Surface Area Architecture Specification" for additional
details. The MSA is further explained in the "Build Packaging Specification"
document.
C) Module Build Description (MDB). The "as-built" definition file that contains
only the changes to the default flags defined in the MSA. The MSA and MDB are
further explained in the "Build Packaging Specification" document.
D) Platform Configuration Database (PCD). A platform database which contains a
variety of current platform settings or directives by which a driver or
application can interact with. The PCD is defined by the PCD_Protocol (This is
further explained in the "Platform Configuration Database Infrastructure
Description" document.
E) Library Class. A library class is a logical grouping of similar functions.
When developing components, the module surface area declares the class of
libraries that can be used by the component. The MBD file specifies the
instance(s) of the library that will be used during compilation/linking. All
library type modules must include header files in their distribution package,
as well as their surface area and module build description files. Components,
on the other hand, need only provide the binary and build description files
when distributing BINARY packages. The Library Classes are further explained
in the "Build Packaging Specification" document.
=========================================================================
The common operations by developers of new modules are:
-------------------------------------------------------
1) How to manually create a new module in a package:
- The module source code must first be created in an appropriate directory
(under the package the module is to be a part of.)
- An MSA file must be created, spelling out all aspects of the module.
- The MSA must be added to the SPD for the package to include the module.
-----------------------------------------
2) Add/Remove module(s) to/from a package:
- Setup environment as Build
- Add a module to a package
* Generate the module SurfaceArea description file and build description
file
* Run GenBuildFile.bat under <PackageDir> to generate an entrance
build.xml for the module
* Add a new <MsaFile> element under <MsaFiles> into
<PackageDir>\<PackageName>.spd, using relative path to package
* Add a new <ModuleSA> entry under each <TianoImage> into
<PackageDir>\<PackageName>.fpd file
- Remove a module from a package
* Comment out or remove corresponding <MsaFile> element under <MsaFiles>
from <PackageDir>\<PackageName>.spd
* Comment out or remove corresponding <ModuleSA> entry under each
<TianoImage> from <PackageDir>\<PackageName>.fpd
-----------------------------------
3) How to manually create a package:
- Identify the modules that are to be members of the project.
- Identify the Variables and Guids required in and of the Package (including
consumption/production information).
- Create an SPD file defining these modules and calling out their MSA files.
--------------------------------------
4) Declare a new Protocol in a package:
- This release requires manual editing of the SPD file, adding the protocol
to the ProtocolDeclarations section of the file.
- Add the Protocol .h file to the Include\Protocol directory.
- Add an entry to the Protocol.info file
* Each line contains Protocol base name then the global variable name and
then the hex value of the Protocol GUID.
Example Protocol.info file (2 lines):
UnicodeCollation gEfiUnicodeCollationProtocolGuid
{ 0x1d85cd7f, 0xf43d, 0x11d2, 0x9a, 0xc, 0x0, 0x90, 0x27, 0x3f, 0xc1, 0x4d }
UsbHc gEfiUsbHcProtocolGuid
{ 0xf5089266, 0x1aa0, 0x4953, 0x97, 0xd8, 0x56, 0x2f, 0x8a, 0x73, 0xb5, 0x19 }
---------------------------------
5) Declare a new PPI in a package:
- This release requires manual editing of the SPD file
- Add the PPI .h file to the Include\Ppi directory.
- Add an entry to the Ppi.info file
* Each line contains PPI base name then the global variable name and then
the hex value of the PPI GUID.
Example Ppi.info file (2 lines):
NtPeiLoadFile gNtPeiLoadFilePpiGuid
{ 0xfd0c65eb, 0x405, 0x4cd2, 0x8a, 0xee, 0xf4, 0x0, 0xef, 0x13, 0xba, 0xc2 }
NtThunk gPeiNtThunkPpiGuid
{ 0x98c281e5, 0xf906, 0x43dd, 0xa9, 0x2b, 0xb0, 0x3, 0xbf, 0x27, 0x65, 0xda }
----------------------------------
6) Declare a new GUID in a package:
- This release requires manual editing of the SPD file to include the new
Guid.
---------------------------------------
7) Declare a new PCD entry in a package:
- This release requires manual editing of the SPD file to include the new
PCD.
------------------------------
8) Declare a new Library Class:
- This release requires manual editing of the SPD file to include the new
Library Class.
--------------------------------------
9) Add a library instance to a package:
- This requires manual MSA and MBD file.
-----------------------------
10) Add a module to a package:
- This requires manual MSA and MBD editing
=======================================================
Notes:
------
The EDK 2.0 represents significant changes in the structure of the EDK.
Therefore it is very difficult to isolate all of the changes of this version of
the EDK with the previous (EDK 1.0) version.
Of particular note:
1) EDK 2.0 contains new hardware feature support for the ICH SMBUS Libraries.
These libraries are provided to make Memory Reference Code (MRC) development
easier.
2) The MDE Libraries - The MDE libraries resent significant changes in source
(with only limited changes in functionality.) These new libraries conform
to the "MDE Library Specification".
3) The Fat Binary and the EDK Shell Binary Packages are functionally identical
to the EDK 1.0 version.
4) The EDK tools directory has been expanded to include more tools and more
tool functionality.
5) The EDK NT32 section has been ported to the new build process, but
functionally remains the same as the EDK 1.0 version.
6) The Application "HelloWorld" has been ported to EDK 2.0 as well.
