Michael D Kinney 868254ace3 EmulatorPkg: Fix VS20xx IA32 boot failure
https://bugzilla.tianocore.org/show_bug.cgi?id=2056

The IA32 build of the EmulatorPkg for VS20xx does not boot
because the default value of PCD PcdPeiServicesTablePage
rarely succeeds to be mapped on IA32 Windows Host Environments.
Change the DEC default value for this PCD to a value that
is compatible with Windows and POSIX host environments for
IA32 and X64.  For IA32 builds, this 64-bit PCD is truncated
to a 32-bit value.

PcdPeiServicesTablePage is changed from 0x1003000000 to
0x1013000000.  With this new value, no boot failures are
observed.  However, the use of this hard coded value can
potentially cause a boot failure if this address specified
by the PCD is already allocated in the user process.

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 -D WIN_SEC_BUILD -a IA32

  • 64bit emulator in Windows:

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

  • 32bit emulator in Linux:

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

  • 64bit emulator in Linux:

    build -p EmulatorPkg\EmulatorPkg.dsc -t GCC5 -D UNIX_SEC_BUILD -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
