Doug Cook (WINDOWS) 9098efdf0d EmulatorPkg: BlockIo2 APIs do not signal event 
BlockIo2 Read/Write/Flush APIs should signal the token's event when the
I/O operation completes, but the Emulator APIs do not. As a result, any
code that tries to implement async I/O will hang on emulator.

Both Windows and Unix emulator hosts work the same way:

- All I/O is completed synchronously.
- All I/O implementations contain the comment:
  `// Caller is responsible for signaling EFI Event`

However, the protocol implementations do not signal the event, so the
event is never signalled.

Fix is to signal the event in the appropriate protocol implementations.

- If the host API returns success then the I/O is complete since it's
  always synchronous.
- If there is a Token and Token->Event is not null and the I/O is
  successful then the event should be signalled.

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 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
