01/27/2018 Configuartion of EDKI

Take this article as the entry of my technical blog. It is embarrassing that the Chinese language support is broken on Ubuntu, so I may have to use English for recording purpose before it can be fixed.

(1) Dependencies of EDKII Environment

The guidance on Tianocore HomePage

`https://github.com/tianocore/tianocore.github.io/wiki/Common-instructions`

To set up the environment in Unix-like OS. Take Ubuntu 16.04LTS as host:

 sudo apt-get install build-essential uuid-dev iasl git gcc-5 nasm
 sudo apt-get install libuuid1=2.27.1-6ubuntu3.3 ### if any version issue

Then build the BaseTool of EDKII and setup the environment variable:

make -C BaseTools
export EDK_TOOLS_PATH=/home/ubuntu/Desktop/Tiano/edk2/BaseTools
cd .. && source edksetup.sh BaseTools

(2) Build OVMF Pkg and run with QEMU

Example of building specific module with target architecture of IA32 && X64.
Note that we pass the TPM device into QEMU with the CLI parameter.

build -p OvmfPkg/OvmfPkgIa32X64.dsc -t GCC5 -b RELEASE -a IA32 -a X64
sudo apt-get install -y qemu
qemu-img create -f qcow2 ./test.img 30G
qemu-system-x86_64 -display sdl -enable-kvm  \
    -m 1024 -boot c -bios Build/OVMF.fd -boot menu=on -tpmdev \
    cuse-tpm,id=tpm0,path=/dev/vtpm0 \
    -device tpm-tis,tpmdev=tpm0 ./test.img

Another thing to mention is that with a variant of Native GCC, the building process may crush.

  /tmp/portage/sys-firmware/edk2-9999/work/Build/MdeModule/RELEASE_GCC44/X64/MdeModulePkg/Application/HelloWorld/HelloWorld/DEBUG/HelloWorld.dll unsupported ELF EM_X86_64 relocation 0x18.
GenFw: ERROR 3000: Invalid
  /tmp/portage/sys-firmware/edk2-9999/work/Build/MdeModule/RELEASE_GCC44/X64/MdeModulePkg/Application/HelloWorld/HelloWorld/DEBUG/HelloWorld.dll unsupported ELF EM_X86_64 relocation 0x18.
GenFw: ERROR 3000: Invalid

if this happens, please make sure the version of your GCC is compatible (4.6 or 5). More details please see

(3) Run OVMF with QEMU

we may just assign the bios parameter to unter UEFI shell.

PS: Gnome Sreenshot shortcut of "Alt + Print Screen" is convenient the that of MacroHard.
