There is an inconsistency between the UNIX and Windows implementations of EMU_THUNK_PROTOCOL.SetTime(). The Windows version returns an EFI_STATUS value whereas the the UNIX implementation is VOID. However, the UNIX implementation is an unimplemented stub whereas the Windows version is implementated. The current EMU_THUNK_PROTOCOL function pointer definition specifies a VOID return type. However, EMU_THUNK_PROTOCOL.SetTime() is close to the spec defined gRT->SetTime() except for missing the EFI_STATUS return type. Therefore, I conclude that the most sensible reconciliation is to add the EFI_STATUS return type to the protocol definition.

Overview
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.)

How to Build & Run
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
