During the Incremental build GenerateByteArrayValue used to generate the ByteArrayValue even when there is no change in the PCD/VPDs. which is time consuming API based on the number of PCD/VPDs and SKU IDs. The optimization is that GenerateByteArrayValue is used to store the StructuredPcdsData in a JSON file for each of the arch. and during the Incremental build this API will check, if there is any change in the Structured PCD/VPDs then rest of the flow remains the same. if there is no change then it will return the provious build data. Flow: during the 1st build StructuredPcdsData.json is not exists, StructuredPcdsData will be dumped to json file. and it will copy the output.txt as well. Note: as the output.txt are different for different Arch, so it will be stored in the Arch folder. During the Incremental build check if there is any change in Structured PCD/VPD. if there is a change in Structured VPD/PCD then recreate the StructuredPcdsData.json, and rest of the flow remains same. if there is no change in VPD/PCD read the output.txt and return the data Unit Test: Test1: Modified the Structured Pcds default from DEC file. current flow is executing. Test2: Override the default value of the PCD from DEC file. current flow is executing. Test3: Modified/Override the PCD from DSC file. current flow executing Test4: Modified/Override the FDF from DSC file. current flow executing Test5: update the default value from Command Line.current flow executing Test6: Build without change in PCD in DSC, FDF, DEC and Command Line the proposed changes will be executing, and the return data remains the same with and without the changes. Test7: Build with and without modified the include headers of Structured PCDs. if there is any change in those Structured PCD header then current flow will be executed. With these changes it's helping to save around ~2.5min to ~3.5min of Incremental build time in my build environment.

:: Note: New build instructions are available. It is recommended to start with the new instructions if learning how to build edk2 and/or BaseTools for the first time. This page is retained for reference. New instructions: `Build Instructions`_ .. _`Build Instructions`: https://github.com/tianocore/tianocore.github.io/wiki/Build-Instructions This directory contains the EDK II build tools and template files. Templates are located in the Conf directory, while the tools executables for Microsoft Windows Operating Systems are located in the Bin\\Win32 directory, other directory contains tools source. Build step to generate the binary tools --------------------------------------- Windows/Visual Studio Notes =========================== To build the BaseTools, you should run the standard vsvars32.bat script from your preferred Visual Studio installation or you can run get_vsvars.bat to use latest automatically detected version. In addition to this, you should set the following environment variables:: * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree * BASE_TOOLS_PATH - The directory where the BaseTools source is located. (It is the same directory where this README.rst is located.) After this, you can run the toolsetup.bat file, which is in the same directory as this file. It should setup the remainder of the environment, and build the tools if necessary. Unix-like operating systems =========================== To build on Unix-like operating systems, you only need to type ``make`` in the base directory of the project. Ubuntu Notes ============ On Ubuntu, the following command should install all the necessary build packages to build all the C BaseTools:: sudo apt install build-essential uuid-dev
