EmulatorPkg provides an environment where a UEFI environment can be emulated under an environment where a full UEFI compatible environment is not possible. (For example, running under an OS where an OS process hosts the UEFI emulation environment.)

• Builds and runs under
  • a posix-like environment with X windows
    • Linux
    • OS X
  • Windows environment
    • Win10 (verified)
    • Win8 (not verified)

You can use the following command to build.

• 32bit emulator in Windows:

  build -p EmulatorPkg\EmulatorPkg.dsc -t VS2017 -a IA32

• 64bit emulator in Windows:

  build -p EmulatorPkg\EmulatorPkg.dsc -t VS2017 -a X64

• 32bit emulator in Linux:

  build -p EmulatorPkg\EmulatorPkg.dsc -t GCC5 -a IA32

• 64bit emulator in Linux:

  build -p EmulatorPkg\EmulatorPkg.dsc -t GCC5 -a X64

You can start/run the emulator using the following command:

• 32bit emulator in Windows:

  cd Build\EmulatorIA32\DEBUG_VS2017\IA32\ && WinHost.exe

• 64bit emulator in Windows:

  cd Build\EmulatorX64\DEBUG_VS2017\X64\ && WinHost.exe

• 32bit emulator in Linux:

  cd Build/EmulatorIA32/DEBUG_GCC5/IA32/ && ./Host

• 64bit emulator in Linux:

  cd Build/EmulatorX64/DEBUG_GCC5/X64/ && ./Host

On posix-like environment with the bash shell you can use EmulatorPkg/build.sh to simplify building and running emulator.

For example, to build + run:

$ EmulatorPkg/build.sh $ EmulatorPkg/build.sh run

The build architecture will match your host machine's architecture.

On X64 host machines, you can build + run IA32 mode as well:

$ EmulatorPkg/build.sh -a IA32 $ EmulatorPkg/build.sh -a IA32 run
