92 The EDK II is being managed by the Subversion Source Control on Tianocore.org.
93 This software package provides speed, security, and additional features. The
94 recommended client is TortoiseSVN version 1.3.3.
95 (Available at http://tortoisesvn.tigris.org/)
97 There are instructions for the use of Subversion Source Control on the
98 Tianocore.org website, as part of the checkout procedures.
100 The URL of the EDK II repository is:
101 https://edk2.tianocore.org/svn/edk2/trunk/edk2
103 -----------------------
104 Notes On Documentation
105 -----------------------
106 The documents are being managed by the Subversion Source Control on
107 Tianocore.org. The document repository is "docs" and must be checked out
108 separately from the EDK II source tree. Refer to the checkout procedures on
109 the Tianocore.org website for EDK II.

116 Notes On Required Tools (With examples for Windows, OS X, and Linux)
117 -----------------------
118 Software Installation Order:
119 After installing the compiler tools and your Subversion client, the following
120 required tools should be installed in order:
121 Java JDK, Apache-Ant, ant-contrib, xmlbeans, saxon8
123 Java Development Kit:
125 The Java Environment Variable must be set before attempting to build.
126 For Sun JDK (see note below*):
127 set JAVA_HOME=c:\Java\jdk1.5.0_06 (Windows example)
128 export JAVA_HOME=/Library/Java/Home/ (OS X example)
129 export JAVA_HOME=/usr/lib/j2sdk1.5-sun/ (Linux example)
131 set JAVA_HOME=c:\Java\jrockit-R26.0.0-jdk1.5.0_04
133 *When using the Sun JDK5.0
134 During installation, you should specify the install directory as C:\Java
135 instead of C:\Program Files\(or some other drive letter.) While installing
136 to this non-standard location is not required. In use, it seems to work
138 For the JDK, the install path would be C:\Java\jdk1.5.0_06
139 For the JRE, the install path would be C:\Java\jre1.5.0_06
140 Alternatively, you can specify C:\sunjavajdk and C:\sunjavajre.
142 NOTE: You cannot combine the location for the JDK and the JRE, as the JRE
143 install removes most of the binaries and libraries installed by the JDK
147 The Apache-ANT requires the ANT_HOME environment variable to be set before
149 i.e. set ANT_HOME=c:\<full path to where ant was installed>
150 export ANT_HOME=~/ExternalTools/apache-ant (OS X and Linux example)
152 The ant-contrib.jar file should be installed in the %ANT_HOME%\lib
155 The XMLBeans, requires the XMLBEANS_HOME environment variable to be set
156 before attempting to build:
157 i.e. set XMLBEANS_HOME=C:\<full path to where xmlbeans was installed>
158 export XMLBEANS_HOME=~/ExternalTools/xmlbeans (OS X and Linux example)
160 The saxon8.jar file should be copied to the %XMLBEANS_HOME%\lib directory.
162 The Ant and XMLBean tools are required to be in the path.
164 set PATH=%PATH%;%ANT_HOME%\bin;%XMLBEANS_HOME%\bin
165 Linux/OS X bash shell example:
166 export PATH=$PATH:${ANT_HOME}/bin:${XMLBEANS_HOME}/bin
168 -------------------------------------------------------------------------------
171 Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to
172 checkout the entire EDK II source tree.
174 In a command window, change to the top level directory of the Edk II sources.
176 If the active compiler tool chain is GCC, you must set the
177 environment variable, TOOL_CHAIN to "gcc" before running the
178 edksetup script. Example: export TOOL_CHAIN=gcc
180 To test your tool chain setup and to build the Supplied Tools, execute:
181 c:\MyWork\edkii\> edksetup ForceBuild
183 On Unix systems you must source the edksetup.sh file to load the correct
184 settings into your shell.
186 . edksetup.sh # Note the dot.
188 (This command will be referred to as the setup command throughout the rest of
190 NOTE: You should run the setup command at the start of every session.
191 This configures the environment to include the TianoTools and the
192 Java applications and libraries.
194 Any changes to the tool source code or XML Schema documents will require that
196 c:\MyWork\edkii\> edksetup ForceBuild
198 You will need to set the WORKSPACE environment variable, or run the edksetup
199 script (without any arguments) any time you want to build.
201 Set the WORKSPACE environment variable, e.g.:
203 c:\> set WORKSPACE=C:\MyWork\edkii
205 You may need to edit the text files, Tools/Conf/target.txt and/or
206 Tools/Conf/tools_def.txt (created by edksetup,) using your favorite
207 text editor to point to the tools you want to use to build EDK II binaries.
209 Once this is completed, you are ready to test the Build, by executing:
210 c:\MyWork\edkii\> build
212 This command builds active platform specified in text file target.txt. If
213 active platform is not specified, go to sub-directory which contains FPD files and
214 type build. More information about active platform policy reference to specification
215 <<EDK II Build and Packaging Architecture Specification>>.
217 -------------------------
218 Individual Platform Builds
219 -------------------------
220 After running the setup command, you can build individual platforms.
221 In the command window,
222 1. Set active platform in target.txt, and type "build" in whatever directory;
223 2. or cd to the platform (FPD file) that you want to build, and just type:
224 c:\MyWork\edkii\EdkNt32Pkg\> build
226 Note that active platform with the high priority to build, that means active
227 platform will be built even if exists FPD file under current directory. More
228 information about active platform policy reference to specification
229 <<EDK II Build and Packaging Architecture Specification>>.
231 Go to <full build path>\DEBUG\MSFT\IA32 and execute SecMain.exe
232 to run the Nt32 emulation platform under Microsoft Windows.
234 To exit the Nt32 emulation platform, you may type reset at the EFI Shell>
235 command prompt. Alternately, you may use the Graphical interface, Boot
236 Maintenance Manager screen's Reset System command.
238 ------------------------
239 Individual Module Builds
240 ------------------------
241 After running the setup command, you can build individual modules.
242 In the command window, cd to the module that you want to build, and just
244 c:\MyWork\edkii\MdePkg\Library\BaseLib\> build
246 Note active platform must be set for individual module build.
248 -------------------------------------------------------------------------------
251 The Apache-ANT program is a build tool that uses XML-based project files.
252 Similar to Makefiles, these project files may contain multiple targets. Most
253 build.xml files in EDK II are auto-generated; any edits performed on the
254 build.xml files will be overwritten the next time build is executed.
256 Pre-defined targets in the build.xml file include:
257 all - This target builds binaries for defined architectures
258 clean - This target removes object files generated by commands
259 cleanall - This target removes all generated files and directories.
261 A Word on GCC tool chain
262 ------------------------
263 EDK II will not compile with a standard Linux gcc tool chain. While Linux
264 distributions are usually based on ELF, EDK II requires a version of gcc
265 that is configured to produce PE-COFF images. You will find a script in
266 edk2/Tools/gcc that will download, configure, compile, and install a gcc
267 4.X cross-compile tool chain for EDK II development. It has support for
268 the IA32 architecture. It can be built and run on Cygwin, Linux, and many
269 other POSIX compliant host operating environments. There are a few tools
270 that you will need on your host computer in order to compile the tool
271 chain. Among them are bash, gcc, gmake, curl (or wget).
273 -------------------------------------------------------------------------------
276 ===============================================================
281 A) Surface Area Package Description (SPD) file contains information about the
282 modules that the package contains, including the location of all MSA files, and
283 public library names and headers that might be provided by a module in the
284 package. Packages are defined by SPD files. (Found in the root of the Package
285 subdirectory (i.e. EdkNt32Pkg)) The SPD is further explained in the "EDK Build
286 and Packaging Architecture Specification" document.
288 B) Module Surface Area Definition (MSA) files. A description of a module's
289 surface area, with all module specific default flags and features specified.
290 Refer to the "Module Surface Area Architecture Specification" for additional
291 details. The MSA is further explained in the "EDK II Build Packaging Architecture
292 Specification" document.
294 C) Framework Platform Description (FPD) files. A description of a platform's
295 surface are, including a list of modules that are needed by the platform. To
296 support individual module builds, developers are not required to provide
297 information about specific flash devices, nor flash device layout. There are
298 specific sections in the FPD file that do control aspects of the build, such
299 as the Supported Architectures and Build Targets, as well as the tool flags
300 that are used to create the binary files. A valid platform file can specify
301 zero or more modules, so individual modules can be compiled within the context
302 of a platform (FPD) definition.
304 D) Platform Configuration Database (PCD). A platform database which contains a
305 variety of current platform settings or directives by which a driver or
306 application can interact with. The PCD is defined by the PCD_Protocol (This is
307 further explained in the "Platform Configuration Database Infrastructure
308 Description" document.
310 E) Library Class. A library class is a logical grouping of similar functions.
311 When developing components, the module surface area declares the class of
312 libraries that can be used by the component. The MSA and SPD files can specify
313 a recommended instance of the library that a platform integrator may select,
314 however this is only a recommendation. The PI may choose to select a different
315 library instance to be used during compilation/linking. All library type modules
316 must include header files in their distribution package, as well as their MSA
317 files. Components, on the other hand, need only provide an MSA and either source
318 or binary files when distributing packages. The Library Classes are further
319 explained in the "EDK II Build and Packaging Architecture Specification"
322 =========================================================================
323 The common operations by developers of new modules are:
324 -------------------------------------------------------
326 1) How to manually create a new module in a package:
327 - The module source code must first be created in an appropriate directory
328 (under the package the module is to be a part of.)
329 - An MSA file must be created, spelling out all aspects of the module.
330 - The MSA must be added to the SPD for the package to include the module.
332 -----------------------------------------
333 2) Add/Remove module(s) to/from a package:
335 - Setup environment as Build
336 - Add a module to a package
337 * Generate the module SurfaceArea description file
338 * Add a new <Filename> element under <MsaFiles> into
339 <PackageDir>\<PackageName>.spd, using relative path to package
340 * Add a new <ModuleSA> entry under each <FrameworkModules> into
341 <PackageDir>\<PackageName>.fpd file if necessary.
343 - Remove a module from a package
344 * Comment out or remove corresponding <Filename> element under <MsaFiles>
345 from <PackageDir>\<PackageName>.spd
346 * Comment out or remove corresponding <ModuleSA> entry under each
347 <FrameworkModules> from <PackageDir>\<PackageName>.fpd if necessary.
349 -----------------------------------
350 3) How to manually create a package:
351 - Identify the modules that are to be members of the project.
352 - Identify the Variables and Guids required in and of the Package (including
353 consumption/production information).
354 - Create an SPD file defining these modules and calling out their MSA files.
355 - add a new <Filename> element under <PackageList> into
356 Tools\Conf\FrameworkDatabase.db, using the relative path to workspace.
358 --------------------------------------
359 4) Declare a new Protocol in a package:
360 - This release requires manual editing of the SPD file, adding the protocol
361 to the ProtocolDeclarations section of the file.
362 - Add the Protocol .h file to the Include\Protocol directory.
363 - Add an <Entry> to the <ProtocolDeclarations> element in the
364 <PackageName>.spd file
365 * Each line contains Protocol base name then the global variable name and
366 then the hex value of the Protocol GUID.
368 Example Protocol Entries (NOTE: The Guid entry is a single line in the SPD file):
369 <ProtocolDeclarations>
371 <C_Name>gEfiBdsArchProtocolGuid</C_Name>
372 <GuidValue>665E3FF6-46CC-11D4-9A38-0090273FC14D</GuidValue>
376 <C_Name>gEfiCpuArchProtocolGuid</C_Name>
377 <GuidValue>26BACCB1-6F42-11D4-BCE7-0080C73C8881</GuidValue>
380 </ProtocolDeclarations>
382 ---------------------------------
383 5) Declare a new PPI in a package:
384 - This release requires manual editing of the SPD file
385 - Add the PPI .h file to the Include\Ppi directory.
386 - Add an <Entry> to the package <PpiDeclarations> element in the
387 <PackageName>.spd file
388 * Each line contains PPI base name then the global variable name and then
389 the hex value of the PPI GUID.
391 Example Ppi Entries (NOTE: The Guid entry is a single line in the SPD file):
393 <Entry Name="BootInRecoveryMode">
394 <C_Name>gEfiPeiBootInRecoveryModePpiGuid</C_Name>
395 <GuidValue>17EE496A-D8E4-4B9A-94D1-CE8272300850</GuidValue>
399 <C_Name>gEfiPeiCpuIoPpiInServiceTableGuid</C_Name>
400 <GuidValue>E6AF1F7B-FC3F-46DA-A828-A3B457A44282</GuidValue>
405 ----------------------------------
406 6) Declare a new GUID in a package:
407 - This release requires manual editing of the SPD file to include the new
408 Guid. This is identical to adding a ProtocolDeclaration or PpiDeclaration
409 element as described above.
411 ---------------------------------------
412 7) Declare a new PCD entry in a package:
413 - This release requires manual editing of the SPD file to include the new
414 PCD. New Pcd entries are added to the PcdDefinitions section of the
415 <PackageName>.spd file using the following example for the format:
416 NOTE: The hex <Token> value must be unique.
419 <PcdEntry ItemType="FIXED_AT_BUILD">
420 <C_Name>PcdMaximumUnicodeStringLength</C_Name>
421 <Token>0x00000001</Token>
422 <TokenSpaceGuidCName>gEfiMdePkgTokenSpaceGuid</TokenSpaceGuidCName>
423 <DatumType>UINT32</DatumType>
424 <ValidUsage>FIXED_AT_BUILD</ValidUsage>
425 <DefaultValue>1000000</DefaultValue>
426 <HelpText>The maximum lengh for unicode string.</HelpText>
430 ------------------------------
431 8) Declare a new Library Class:
432 - This release requires manual editing of the SPD file to include the new
433 Library Class. New Library Class entries are added to the
434 LibraryClassDeclarations seection of the <PackageName>.spd file using
435 the following example for the format:
437 <LibraryClassDeclarations>
438 <LibraryClass Name="BaseLib">
439 <IncludeHeader>Include/Library/BaseLib.h</IncludeHeader>
442 <LibraryClass Name="BaseMemoryLib">
443 <IncludeHeader>Include/Library/BaseMemoryLib.h</IncludeHeader>
446 </LibraryClassDeclarations>
448 =======================================================
451 The EDK II represents significant changes in the structure of the EDK.
452 Therefore it is very difficult to isolate all of the changes of this version of
453 the EDK with the previous (EDK 1.0) version.
457 1) EDK II contains new hardware feature support for the ICH SMBUS Libraries.
458 These libraries are provided to make Memory Reference Code (MRC) development
460 2) The MDE Libraries - The MDE libraries represent significant changes in source
461 (with only limited changes in functionality.) These new libraries conform
462 to the "MDE Library Specification".
463 3) The Fat Binary and the EDK Shell Binary Packages are functionally identical
464 to the EDK 1.0 version.
465 4) The EDK tools directory has been expanded to include more tools and more
467 5) The EDK NT32 section has been ported to the new build process, but
468 functionally remains the same as the EDK 1.0 version.
469 6) The Application "HelloWorld" has been ported to EDK II as well.
