Doug Cook (WINDOWS) d1fccbf494 EmulatorPkg: spurious failure in WriteBlocks on X64 
WinNtBlockIoWriteBlocks can spuriously fail on X64. This occurs because
&BytesWritten is a `UINTN*` (i.e. `UINT64*`) but is cast to `LPDWORD`
(i.e. `UINT32*`). Only the low 32 bits are initialized by WriteFile, so
the high 32 bits are uninitialized. This means we will spuriously fail
the `BytesWritten != BufferSize` test.

This doesn't occur on X86-32 since UINTN is the same as DWORD in that
case.

Fix is to declare BytesWritten as DWORD to match the type expected by
WriteFile. This also makes the cast unnecessary.

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.)

Status

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

How to Build & Run

You can use the following command to build.

  • 32bit emulator in Windows:

    build -p EmulatorPkg\EmulatorPkg.dsc -t VS2022 -a IA32

  • 64bit emulator in Windows:

    build -p EmulatorPkg\EmulatorPkg.dsc -t VS2022 -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_VS2022\IA32\ && WinHost.exe

  • 64bit emulator in Windows:

    cd Build\EmulatorX64\DEBUG_VS2022\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
