Notes On Required Tools (Source Control System)\r
-----------------------\r
The EDK II is being managed by the Subversion Source Control on Tianocore.org.\r
This software package provides speed, security, and additional features. The\r
recommended client is TortoiseSVN version 1.3.3. \r
 (Available at http://tortoisesvn.tigris.org/)\r
\r
There are instructions for the use of Subversion Source Control on the\r
Tianocore.org website, as part of the checkout procedures.\r
\r
The URL of the EDK II repository is:\r
  https://edk2.tianocore.org/svn/edk2/trunk/edk2\r
\r
\r
-----------------------\r
Notes On Required Tools (With examples for Windows, OS X, and Linux) \r
-----------------------\r
Software Installation Order:\r
  After installing the compiler tools and your Subversion client, the following\r
  required tools should be installed in order: \r
    Java JDK, Apache-Ant, ant-contrib, xmlbeans, saxon8\r
\r
Java Development Kit:\r
 \r
   The Java Environment Variable must be set before attempting to build.\r
       For Sun JDK (see note below*):\r
              set JAVA_HOME=c:\Java\jdk1.5.0_06  (Windows example)\r
              export JAVA_HOME=/Library/Java/Home/ (OS X example)\r
              export JAVA_HOME=/usr/lib/j2sdk1.5-sun/ (Linux example)\r
       For Bea Systems:\r
              set JAVA_HOME=c:\Java\jrockit-R26.0.0-jdk1.5.0_04\r
 \r
  *When using the Sun JDK5.0\r
    During installation, you should specify the install directory as C:\Java\r
    instead of C:\Program Files\(or some other drive letter.)  While installing\r
    to this non-standard location is not required. In use, it seems to work \r
    more reliably. \r
    For the JDK, the install path would be C:\Java\jdk1.5.0_06\r
    For the JRE, the install path would be C:\Java\jre1.5.0_06\r
    Alternatively, you can specify C:\sunjavajdk and C:\sunjavajre.\r
\r
    NOTE: You cannot combine the location for the JDK and the JRE, as the JRE\r
    install removes most of the binaries and libraries installed by the JDK\r
    install.\r
\r
Java Tools:\r
    The Apache-ANT requires the ANT_HOME environment variable to be set before\r
    attempting to build:\r
         i.e.  set ANT_HOME=c:\<full path to where ant was installed>\r
          export ANT_HOME=~/ExternalTools/apache-ant (OS X and Linux example)\r
\r
    The ant-contrib.jar file should be installed in the %ANT_HOME%\lib \r
    directory.\r
\r
    The XMLBeans, requires the XMLBEANS_HOME environment variable to be set\r
    before attempting to build:\r
         i.e. set XMLBEANS_HOME=C:\<full path to where xmlbeans was installed>\r
          export XMLBEANS_HOME=~/ExternalTools/xmlbeans (OS X and Linux example)\r
\r
    The saxon8.jar file should be copied to the %XMLBEANS_HOME%\lib directory.\r
\r
   The Ant and XMLBean tools are required to be in the path.\r
     MS system example:\r
        set PATH=%PATH%;%ANT_HOME%\bin;%XMLBEANS_HOME%\bin\r
     Linux/OS X bash shell example:\r
        export PATH=$PATH:${ANT_HOME}/bin:${XMLBEANS_HOME}/bin\r
\r
--------------------\r
A Word on Apache-ANT\r
--------------------\r
The Apache-ANT program is a build tool that uses XML-based project files.\r
Similar to Makefiles, these project files may contain multiple targets.  Most\r
build.xml files in EDK II are auto-generated; any edits performed on the\r
build.xml files will be overwritten the next time build is executed.\r
\r
Pre-defined targets in the build.xml file include:\r
    all      - This target builds binaries for defined architectures\r
    clean    - This target removes object files generated by commands\r
    cleanall - This target removes all generated files and directories.\r
\r
------------------------\r
A Word on GCC tool chain\r
------------------------\r
EDK II will not compile with a standard Linux gcc tool chain. While Linux\r
distributions are usually based on ELF, EDK II requires a version of gcc \r
that is configured to produce PE-COFF images. You will find a script in \r
edk2/Tools/gcc that will download, configure, compile, and install a gcc \r
4.X cross-compile tool chain for EDK II development. It has support for \r
the IA32 architecture. It can be built and run on Cygwin, Linux, and many \r
other POSIX compliant host operating environments. There are a few tools\r
that you will need on your host computer in order to compile the tool \r
chain. Among them are bash, gcc, gmake, curl (or wget).\r
\r
\r
-----------------------\r
Notes On Documentation\r
-----------------------\r
The documents are being managed by the Subversion Source Control on\r
Tianocore.org.  The document repository is "docs" and must be checked out\r
separately from the EDK II source tree. Refer to the checkout procedures on\r
the Tianocore.org website for EDK II.\r
\r
The URL of the document repository is:\r
  https://edk2.tianocore.org/svn/edk2/trunk/docs\r
\r
 \r
-------------------------------------------------------------------------------\r
Quick Start \r
-----------\r
(assumes Microsoft Tools and OS Environment, for GCC Tools or Unix, please see \r
"Detailed Starting Instructions" below)\r
\r
Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to\r
checkout the entire EDK II source tree.\r
\r
In a command window, change to the top level directory of the Edk II sources.\r
\r
To test your tool chain setup and to build the Supplied Tools, execute:\r
    c:\MyWork\edkii\> edksetup ForceBuild\r
\r
(The edksetup command will be referred to as the setup command throughout the \r
rest of this document.)\r
      NOTE: You should run the setup command at the start of every session.\r
            This configures the environment to include the TianoTools and the\r
            Java applications and libraries.\r
\r
You will need to set the WORKSPACE environment variable, or run the edksetup\r
script (without any arguments) any time you want to build.\r
\r
  Set the WORKSPACE environment variable, e.g.:\r
\r
    c:\> set WORKSPACE=C:\MyWork\edkii\r
\r
You may need to edit the text files, Tools/Conf/target.txt and\r
Tools/Conf/tools_def.txt (created by edksetup,) using your favorite \r
text editor to ensure that the paths to the tools you want to use \r
to build EDK II binaries are correct.  These files contain the default \r
paths (as per the default installation of the tools), so a customized \r
install may require this manual process.\r
\r
Once this is completed, you are ready to test the Build, by executing:\r
    c:\MyWork\edkii\> build\r
\r
This command builds active platform specified in text file target.txt. If \r
active platform is not specified, go to sub-directory which contains FPD files and\r
type build. More information about active platform policy reference to specification\r
<<EDK II Build and Packaging Architecture Specification>>.\r
\r
-------------------------------------------------------------------------------\r
Detailed Start Instructions\r
---------------------------\r
\r
Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to\r
checkout the entire EDK II source tree.\r
\r
In a command window, change to the top level directory of the Edk II sources.\r
\r
If the active compiler tool chain is GCC, you must set the\r
environment variable, TOOL_CHAIN to "gcc" before running the\r
edksetup script.  Example: export TOOL_CHAIN=gcc\r
\r
To test your tool chain setup and to build the Supplied Tools, execute:\r
    c:\MyWork\edkii\> edksetup ForceBuild\r
\r
On Unix systems you must source the edksetup.sh file to load the correct\r
settings into your shell.\r
\r
    . edksetup.sh # Note the dot.\r
\r
The edksetup command will be referred to as the setup command throughout the \r
rest of this document.)\r
      NOTE: You should run the setup command at the start of every session.\r
            This configures the environment to include the TianoTools and the\r
            Java applications and libraries.\r
\r
Any changes to the tool source code or XML Schema documents will require that\r
you run:\r
   c:\MyWork\edkii\> edksetup ForceBuild\r
\r
You will need to set the WORKSPACE environment variable, or run the edksetup\r
script (without any arguments) any time you want to build.\r
\r
  Set the WORKSPACE environment variable, e.g.:\r
\r
    c:\> set WORKSPACE=C:\MyWork\edkii\r
\r
You may need to edit the text files, Tools/Conf/target.txt and\r
Tools/Conf/tools_def.txt (created by edksetup,) using your favorite \r
text editor to ensure that the paths to the tools you want to use \r
to build EDK II binaries are correct.  These files contain the default \r
paths (as per the default installation of the tools), so a customized \r
tool installation may require this manual process.\r
\r
Once this is completed, you are ready to test the Build, by executing:\r
    c:\MyWork\edkii\> build\r
\r
This command builds active platform specified in text file target.txt. If \r
active platform is not specified, go to sub-directory which contains FPD files and\r
type build. More information about active platform policy reference to specification\r
<<EDK II Build and Packaging Architecture Specification>>.\r
\r
-------------------------\r
Individual Platform Builds\r
-------------------------\r
After running the setup command, you can build individual platforms.\r
  In the command window, \r
  1. Set active platform in target.txt, and type "build" in whatever directory;\r
  2. or cd to the platform (FPD file) that you want to build, and just type:\r
    c:\MyWork\edkii\EdkNt32Pkg\> build\r
\r
  Note that active platform with the high priority to build, that means active \r
  platform will be built even if exists FPD file under current directory. More \r
  information about active platform policy reference to specification\r
  <<EDK II Build and Packaging Architecture Specification>>. \r
\r
Go to <full build path>\DEBUG\MSFT\IA32 and execute SecMain.exe\r
to run the Nt32 emulation platform under Microsoft Windows.\r
\r
To exit the Nt32 emulation platform, you may type reset at the EFI Shell>\r
command prompt.  Alternately, you may use the Graphical interface, Boot\r
Maintenance Manager screen's Reset System command.\r
\r
------------------------\r
Individual Module Builds\r
------------------------\r
After running the setup command, you can build individual modules.\r
  In the command window, cd to the module that you want to build, and just\r
  type:\r
    c:\MyWork\edkii\MdePkg\Library\BaseLib\> build\r
\r
  Note active platform must be set for individual module build. \r
\r
-------------------------------------------------------------------------------\r
\r
General Information:\r
===============================================================    \r
Mechanisms:\r
----------\r
A brief overview:\r
\r
A) Surface Area Package Description (SPD) file contains information about the\r
modules that the package contains, including the location of all MSA files, and\r
public library names and headers that might be provided by a module in the\r
package.  Packages are defined by SPD files.  (Found in the root of the Package\r
subdirectory (i.e. EdkNt32Pkg)) The SPD is further explained in the "EDK Build \r
and Packaging Architecture Specification" document.\r
 \r
B) Module Surface Area Definition (MSA) files.  A description of a module's \r
surface area, with all module specific default flags and features specified.\r
Refer to the "Module Surface Area Architecture Specification" for additional\r
details. The MSA is further explained in the "EDK II Build Packaging Architecture \r
Specification" document.\r
\r
C) Framework Platform Description (FPD) files.  A description of a platform's\r
surface are, including a list of modules that are needed by the platform.  To\r
support individual module builds, developers are not required to provide\r
information about specific flash devices, nor flash device layout.  There are\r
specific sections in the FPD file that do control aspects of the build, such \r
as the Supported Architectures and Build Targets, as well as the tool flags \r
that are used to create the binary files.  A valid platform file can specify \r
zero or more modules, so individual modules can be compiled within the context\r
of a platform (FPD) definition.\r
\r
D) Platform Configuration Database (PCD).  A platform database which contains a\r
variety of current platform settings or directives by which a driver or\r
application can interact with.  The PCD is defined by the PCD_Protocol (This is\r
further explained in the "Platform Configuration Database Infrastructure \r
Description" document.\r
\r
E) Library Class.  A library class is a logical grouping of similar functions.\r
When developing components, the module surface area declares the class of\r
libraries that can be used by the component. The MSA and SPD files can specify\r
a recommended instance of the library that a platform integrator may select,\r
however this is only a recommendation.  The PI may choose to select a different\r
library instance to be used during compilation/linking. All library type modules \r
must include header files in their distribution package, as well as their MSA\r
files. Components, on the other hand, need only provide an MSA and either source\r
or binary files when distributing packages.  The Library Classes are further \r
explained in the "EDK II Build and Packaging Architecture Specification" \r
document.\r
\r
=========================================================================\r
The common operations by developers of new modules are:\r
-------------------------------------------------------\r
\r
1) How to manually create a new module in a package:\r
  - The module source code must first be created in an appropriate directory\r
    (under the package the module is to be a part of.)  \r
  - An MSA file must be created, spelling out all aspects of the module.\r
  - The MSA must be added to the SPD for the package to include the module.\r
\r
-----------------------------------------\r
2) Add/Remove module(s) to/from a package:\r
\r
  - Setup environment as Build\r
  - Add a module to a package\r
     * Generate the module SurfaceArea description file\r
     * Add a new <Filename> element under <MsaFiles> into\r
       <PackageDir>\<PackageName>.spd, using relative path to package\r
     * Add a new <ModuleSA> entry under each <FrameworkModules> into\r
       <PackageDir>\<PackageName>.fpd file if necessary. \r
\r
   - Remove a module from a package\r
     * Comment out or remove corresponding <Filename> element under <MsaFiles>\r
       from <PackageDir>\<PackageName>.spd\r
     * Comment out or remove corresponding <ModuleSA> entry under each\r
       <FrameworkModules> from <PackageDir>\<PackageName>.fpd if necessary. \r
\r
-----------------------------------\r
3) How to manually create a package:\r
  - Identify the modules that are to be members of the project.\r
  - Identify the Variables and Guids required in and of the Package (including\r
    consumption/production information).\r
  - Create an SPD file defining these modules and calling out their MSA files.\r
  - add a new <Filename> element under <PackageList> into \r
    Tools\Conf\FrameworkDatabase.db, using the relative path to workspace. \r
\r
--------------------------------------\r
4) Declare a new Protocol in a package: \r
  - This release requires manual editing of the SPD file, adding the protocol\r
    to the ProtocolDeclarations section of the file. \r
  - Add the Protocol .h file to the Include\Protocol directory.\r
  - Add an <Entry> to the <ProtocolDeclarations> element in the \r
    <PackageName>.spd file\r
     * Each line contains Protocol base name then the global variable name and\r
       then the hex value of the Protocol GUID.\r
\r
Example Protocol Entries (NOTE: The Guid entry is a single line in the SPD file):\r
<ProtocolDeclarations>\r
  <Entry Name="Bds">\r
    <C_Name>gEfiBdsArchProtocolGuid</C_Name>\r
    <GuidValue>665E3FF6-46CC-11D4-9A38-0090273FC14D</GuidValue>\r
    <HelpText/>\r
  </Entry>\r
  <Entry Name="Cpu">\r
    <C_Name>gEfiCpuArchProtocolGuid</C_Name>\r
    <GuidValue>26BACCB1-6F42-11D4-BCE7-0080C73C8881</GuidValue>\r
    <HelpText/>\r
  </Entry>\r
</ProtocolDeclarations>\r
\r
---------------------------------\r
5) Declare a new PPI in a package:\r
 - This release requires manual editing of the SPD file\r
  - Add the PPI .h file to the Include\Ppi directory.\r
  - Add an <Entry> to the package <PpiDeclarations> element in the \r
    <PackageName>.spd file\r
     * Each line contains PPI base name then the global variable name and then\r
       the hex value of the PPI GUID.\r
\r
Example Ppi Entries (NOTE: The Guid entry is a single line in the SPD file):\r
<PpiDeclarations>\r
  <Entry Name="BootInRecoveryMode">\r
    <C_Name>gEfiPeiBootInRecoveryModePpiGuid</C_Name>\r
    <GuidValue>17EE496A-D8E4-4B9A-94D1-CE8272300850</GuidValue>\r
    <HelpText/>\r
  </Entry>\r
  <Entry Name="CpuIo">\r
    <C_Name>gEfiPeiCpuIoPpiInServiceTableGuid</C_Name>\r
    <GuidValue>E6AF1F7B-FC3F-46DA-A828-A3B457A44282</GuidValue>\r
    <HelpText/>\r
  </Entry>\r
</PpiDeclarations>\r
\r
----------------------------------\r
6) Declare a new GUID in a package:\r
  - This release requires manual editing of the SPD file to include the new\r
    Guid.  This is identical to adding a ProtocolDeclaration or PpiDeclaration\r
    element as described above.\r
\r
--------------------------------------- \r
7) Declare a new PCD entry in a package:\r
  - This release requires manual editing of the SPD file to include the new\r
    PCD.  New Pcd entries are added to the PcdDefinitions section of the\r
    <PackageName>.spd file using the following example for the format:\r
    NOTE: The hex <Token> value must be unique.\r
\r
<PcdDeclarations>\r
  <PcdEntry ItemType="FIXED_AT_BUILD">\r
    <C_Name>PcdMaximumUnicodeStringLength</C_Name>\r
    <Token>0x00000001</Token>\r
    <TokenSpaceGuidCName>gEfiMdePkgTokenSpaceGuid</TokenSpaceGuidCName>\r
    <DatumType>UINT32</DatumType>\r
    <ValidUsage>FIXED_AT_BUILD</ValidUsage>\r
    <DefaultValue>1000000</DefaultValue>\r
    <HelpText>The maximum lengh for unicode string.</HelpText>\r
  </PcdEntry>\r
</PcdDeclarations>\r
  \r
------------------------------\r
8) Declare a new Library Class:\r
  - This release requires manual editing of the SPD file to include the new\r
    Library Class.  New Library Class entries are added to the \r
    LibraryClassDeclarations seection of the <PackageName>.spd file using\r
    the following example for the format:\r
\r
<LibraryClassDeclarations>\r
  <LibraryClass Name="BaseLib">\r
    <IncludeHeader>Include/Library/BaseLib.h</IncludeHeader>\r
    <HelpText/>\r
  </LibraryClass>\r
  <LibraryClass Name="BaseMemoryLib">\r
    <IncludeHeader>Include/Library/BaseMemoryLib.h</IncludeHeader>\r
    <HelpText/>\r
  </LibraryClass>\r
</LibraryClassDeclarations>\r

Notes:\r
------\r
The EDK II represents significant changes in the structure of the EDK.\r
Therefore it is very difficult to isolate all of the changes of this version of\r
the EDK with the previous (EDK 1.0) version.\r
\r
Of particular note:\r
\r
1) EDK II contains new hardware feature support for the ICH SMBUS Libraries.\r
   These libraries are provided to make Memory Reference Code (MRC) development\r
   easier.\r
2) The MDE Libraries - The MDE libraries represent significant changes in source\r
   (with only limited changes in functionality.)  These new libraries conform\r
   to the "MDE Library Specification". \r
3) The Fat Binary and the EDK Shell Binary Packages are functionally identical\r
   to the EDK 1.0 version.\r
4) The EDK tools directory has been expanded to include more tools and more\r
   tool functionality.\r
5) The EDK NT32 section has been ported to the new build process, but\r
   functionally remains the same as the EDK 1.0 version.\r
6) The Application "HelloWorld" has been ported to EDK II as well.\r
