X86EmulatorPkg

This code implements a DXE driver for EDK2/Tianocore that allows UEFI drivers built for x86_64 aka X64 aka amd64 to be executed on 64-bit ARM systems (aka AArch64)

All prerequisites in the core code have been merged into the upstream Tianocore EDK2 repository as of commit 26d60374b87d.

A prebuilt RELEASE binary of this driver is included in the edk2-non-osi repository at commit 596043ffb61d5f74.

Quick Start

To quickly compile an OVMF version that contains the emulator, run

$ git clone https://github.com/tianocore/edk2.git
$ cd edk2
$ git submodule add https://github.com/ardbiesheuvel/X86EmulatorPkg.git
$ git submodule update --init
$ echo "  X86EmulatorPkg/X86Emulator.inf" >> ArmVirtPkg/ArmVirtQemu.dsc
$ echo "  INF X86EmulatorPkg/X86Emulator.inf" >> ArmVirtPkg/ArmVirtQemuFvMain.fdf.inc
$ make -C BaseTools
$ . edksetup.sh
$ export GCC5_AARCH64_PREFIX=... (if you are on a non-aarch64 system)
$ build -a AARCH64 -t GCC5 -p ArmVirtPkg/ArmVirtQemu.dsc -b RELEASE (-b DEBUG for debug build)

You can then use QEMU to execute it:

$ qemu-system-aarch64 -M virt -cpu cortex-a57 -m 2G -nographic -bios ./Build/ArmVirtQemu-AARCH64/RELEASE_GCC5/FV/QEMU_EFI.fd

If you see dots on your screen, that is the x86_64 virtio iPXE rom in action!
