Only if I knew how to do that... I can start qemu with -s and attach gdb 
to it but how to get symbols for the OVMF.fd file and how to set the 
breakpoint? I've tried gdb OVMF.fd but it cannot load it directly. I've 
also found *.debug files in the edk2/Build directory but they are only for 
parts of the whole fw image and none of them seems to be for the part 
which defines the IoRead32 function. Does anyone know how to debug OVMF 
firmware running in qemu?
