this post = on Super User, I am trying to add a DXE driver to an OVMF = image I'm building with edk2. Nobody was able to help me there so = I turn here for your help.
create the simplest DXE driver I = managed
In folder MdeModulePkg/Applica= tion/Hello, I have:
include
 
...
 
while (1)
      &n= bsp; SystemTable->ConOut->OutputString(SystemTable->ConOut,
            &= nbsp;                    =         L"It works!\n");
return EFI_SUCCESS;

=  
= Hello.inf : 
[Defines]
  INF_VERSION          =           =3D 0x00010005
  BASE_NAME          &n= bsp;           =3D Hello
  FILE_GUID = ;                     =3D=  ...
  MODULE_TYPE          =           =3D DXE_DRIVER

  • Set OvmfPkg/Ovmf= PkgX64.dsc as my target platform with GCC5 as the toolchain
  • Add MdeModulePkg/Application/Hello/Hel= lo.inf to the end of the component section (I have tried to a= dd it after other certain drivers) in the .dsc file.<= /span>
  • Add MdeModulePkg/Application/Hello/Hello.inf to the end of the <= /span>[FV.DXEFV] section in OvmfPk= gX64.fdf (I have also tried to add it after other certain dri= vers)
  • Run build
  • Run QEMU with the= resulting OVMF image: qemu-system-x86_64 = ;-d int -D log.txt  -bios= OVMF.fd -net none -drive file=3Dfat:rw:bootdrv,format=3Draw
  • QEMU hangs with message "Guest has= not initialized display (yet)"
  • log.txt has = one log: check_exception old: 0xffffffff new 0x6
