+Templates are located in the Conf directory, while the tools executables for
+Microsoft Windows 32-bit Operating Systems are located in the Bin\Win32 directory.
+
+The binary tools will be updated only after passing developer testing.
+
+The BaseTools package will be updated with new tools only after all testing on a set
+of binary tools has successfully completed.
+
+Current state of the tools is Proto-Type - not all tool functions have been implemented
+and there may be bugs in these tools. These tools are under constant development at
+this time.
+
+BaseTools Simple Usage:
+1) Change the directory to the EDK2 root directory, where the edksetup.bat is
+2) Run "edksetup.bat NewBuild"
+3) Set the ACTIVE_PLATFORM to your desired platform description file
+ (%WORKSPACE%\Conf\target.txt)
+4) To build platform, run "build" command in non-module directory
+5) To build module individually, run "build" command in module directory, i.e. where the
+ *.inf file is
+
+Notes:
+1) The tree structure generated by build tools is similar to Ant build system.
+2) Makefile can be called directly by nmake for both top level platform and module. But
+ after you call "nmake cleanall", you have to call "build" command to rebuild platform
+ or modules because the AutoGen.* files have been be removed. The "makefile" itself
+ cannot generate AutoGen.* files. Only "build" command can.
+3) build.exe in %WORKSPACE%\BaseTools\Bin\Win32 is generated from following revision of
+ Python source code:
+ r817 <buildtools_project>\BaseTools\Source\Python\Autogen
+ r817 <buildtools_project>\BaseTools\Source\Python\build
+ r817 <buildtools_project>\BaseTools\Source\Python\Common
+ r817 <buildtools_project>\BaseTools\Source\Python\CommonDataClass
+ r817 <buildtools_project>\BaseTools\Source\Python\GenFds
+
+4) GenFds.exe has is a combo of the follow python source.(This is a temporary branch)
+ r816 <buildtools_project>\BaseTools\Source\Python\Common
+ r816 <buildtools_project>\BaseTools\Source\Python\CommonDataClass
+ r816 <buildtools_project>\BaseTools\Source\Python\GenFds
+
+Brief usage for Migration Tool MigrationMsa2Inf.exe:
+1. Command line format:
+ MigrationMsa2Inf [options]
+2. Input Files:
+ A syntactically valid MSA file
+3. Output Files:
+ An extended INF file with possible auto-generated EntryPoint.c, CommonHeader.h/CommonHeader.txt, depending on options and module contents.
+4. Prerequisite:
+ a. The workspace directory must be specified either by environment variable or -w option.
+ b. The Framework Database file must exist to specify the available packages in current workspace.
+ Two possible locations are: (The first location overrides the second)
+ $(WORKSPACE)\Tools\Conf\FrameworkDatabase.db
+ $(WORKSPACE)\Conf\FrameworkDatabase.db.
+ The <PackageList> field in FrameworkDatabase.db lists all available packages in current workspace.
+ One example:
+ <PackageList>
+ <Filename>MdePkg/MdePkg.nspd</Filename>
+ <Filename>MdeModulePkg/MdeModulePkg.spd</Filename>
+ <Filename>IntelFrameworkPkg/IntelFrameworkPkg.spd</Filename>
+ </PackageList>
+ The package list in FrameworkDatabase.db is important to the final quality of migration:
+ (1) It suggests the new package location: Translate package dependency Guid in MSA to Workspace relative path.
+ If the package dependency Guid cannot be found in current workspace a warning message is raised.
+ (2) It collects the Protocol/Guid/Ppi GuidCName a package contains.
+ The GuidCName acts as "clue" to add e.g. #include <Protocol/DiskIo.h> in CommonHeader.h
+
+5. Example:
+ WORKSAPCE has already been set: $(WORKSPACE) = c:\work\EdkII.
+
+ a. MigrationMsa2Inf -f c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.msa -o c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.inf
+ b. MigrationMsa2Inf -f c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.msa -a
+ Example a & b are equivalent to migrate WinNtThunk driver from EDKII to EDKII' code base.
+
+ c. MigrationMsa2Inf -f c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.msa -a -c
+ The extra "-c" option performs several hardcode mapping due to the naming change in EDKII':
+ OldMdePkg Guid -> MdePkgGuid,
+ EdkModulePkg Guid -> MdeModulePkgGuid,
+ EdkGraphicsLib -> GraphicsLib
+ HiiLib -> HiiLibFramework
+ ...
+
+ d. MigrationMsa2Inf -f c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.msa -m
+ The extra "-m" option suppresses the generation of "CommonHeader.h" and leave all C files intact.
+ Instead, it generates "CommonHeader.txt". Developers can manually copy its content to a local common header file in a module.
+
+6. Known Limitations:
+ a. Tool does not handle Exit Boot Services Callback & Virtual Address Changed Event. Developers need to handle it manually.
+ b. The #include <Library/AbcLib.h> is based on library class naming convention: The header filename for "AbcLib" class are "AbcLib.h" by convention.
+ c. The #include <Guid/Xyz.h>, <Protocol/Xyz.h> and <Ppi/Xyz.h> are added based on gGuidCName listed in MSA.
+ If a GuidCName cannot map to a package Guid/Protocol/Ppi header file, a warning message is raised.
+ If a module uses the definition in a pakcage Guid/Protocol/Ppi header file without list its associative GuidCName, the build will beak. Developer needs to manually add the include statement.
+ d. The [Depex] sections are generated from DXS files with Guid Macro translated to Guid CName by naming convention, etc.
+ If tool fails to "guess" the Guid CName from Guid Macro, it will leave the GuidMacro in [Depex] section for manual resolution.
+ e. When tool generates [Sources] section, the modifiers for source files are lost. (Need to add proper tool chain, etc)
+ f. When tool generates [LibraryClasses] section, the recommended library instances are lost. (No impact to build)

+Brief Usage for PcdSyntax Update:
+Usage:
+ PcdSyntaxUpdate.exe <directory_name>
+It searches all INF, DEC and DSC file under <directory_name> and update them with the following rules:
+1. Update INF files to conform to INF spec 0.44:
+ a. Rename PCD section name: e.g. [PcdsFeatureFlag] -> [FeaturePcd]
+ b. Adjust PCD section item format: e.g. PcdDebugClearMemoryValue|gEfiMdePkgTokenSpaceGuid -> gEfiMdePkgTokenSpaceGuid.PcdDebugClearMemoryValue
+ c. Update the syntax of binary INF file (not PCD related)
+2. Update DEC files to confirm to DEC spec 0.36
+ Adjust PCD section item format: e.g. PcdWinNtPhysicalDisk|0x00001000|gEfiNt32PkgTokenSpaceGuid|VOID*|L"E:RW;245760;512"-> gEfiNt32PkgTokenSpaceGuid.PcdWinNtFlashFvRecoverySize|0x0|UINT32|0x00001011
+3. Update DSC files to confirm to DSC spec
+ a. Adjust string/array typed PCD item format: e.g. PcdWinNtMemorySizeForSecMain|gEfiNt32PkgTokenSpaceGuid|L"64!64"|12 -> gEfiNt32PkgTokenSpaceGuid.PcdWinNtMemorySizeForSecMain|L"64!64"|VOID*|12
+ b. Adjust non-string/array typed PCD item format: e.g. PcdWinNtBootMode|gEfiNt32PkgTokenSpaceGuid|1 -> gEfiNt32PkgTokenSpaceGuid.PcdWinNtBootMode|1
+ c. Update the override library class in [Components] section: e.g.
+ <LibraryClass> {
+ PcdLib|MdePkg/Library/BasePcdLibNull/BasePcdLibNull.inf
+ }
+ To
+ <LibraryClasses> {
+ PcdLib|MdePkg/Library/BasePcdLibNull/BasePcdLibNull.inf
+ }
+
+Brief usage for Migration Tool Spd2Dec.exe:
+1. Command line format:
+ Spd2Dec [options] input_filename
+2. Input File:
+ A syntactically valid SPD file
+3. Output Files:
+ A DEC file whose syntax confirms to DEC spec.
+
+4. Example:
+ a. Spd2Dec -o c:\work\EdkII\Nt32Pkg\Nt32.spd c:\work\EdkII\Nt32Pkg\Nt32.dec
+ b. Spd2Dec -a c:\work\EdkII\Nt32Pkg\Nt32.spd
+ Example a & b are equivalent to migrate Nt32 package SPD file from EDKII to EDKII' snytax.

+
+Brief usage for Migration Tool Fpd2Dsc.exe:
+1. Command line format:
+ Fpd2Dsc [options] input_filename
+2. Input File:
+ A syntactically valid FPD file
+3. Output Files:
+ A DSC file which syntax confirms to DSC spec.
+4. Prerequisite:
+ a. The workspace directory must be specified either by environment variable or -w option.
+
+5. Example:
+ WORKSAPCE has already been set: $(WORKSPACE) = c:\work\EdkII.
+
+ a. Fpd2Dsc -o c:\work\EdkII\Nt32Pkg\Nt32.dsc c:\work\EdkII\Nt32Pkg\Nt32.fpd
+ b. Fpd2Dsc -a c:\work\EdkII\Nt32Pkg\Nt32.fpd
+ Example a & b are equivalent to migrate Nt32 platform description file from EDKII to EDKII' snytax.
+
+6. Known Limitations:
+ a. Tool does not handle Libraries Section since no related info in original FPD file. Developers need to handle it manually in the output DSC file.
+ b. If MSA file which is corresponds to module guid could not be found in currect workspace, tool will dump the module guid.
