Issue: While building edk2, the compiler threw a warning
that was treated as an eror which halted the build
process.
Root Cause: The error was due to a comparison between two
different enum types.
Code Fix: WinGopScreen.c: In function WinNtWndBlt, changed
the comparison between an enum type
"EFI_UGA_BLT_OPERATION" and "EFI_GRAPHICS_OUTPUT_BLT_OPERATION"
to "EFI_UGA_BLT_OPERATION".
Test: The compiled image runs successfully on QEMU.

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 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
