How to do source level debug (OVMF & QEMU & Intel UEFI Development Debugger Tool)

[krishnaLee <sssky307@163.com>]

Hi everyone,
I know nothing about this source level debug mode so I had read some articles and  tried to make this environment,but failed.
I do this as I want to observe how SEC phase jump to PEI phase. 


#1 build ovmf:
build -p OvmfPkg/OvmfPkgIa32.dsc -a IA32 -D DEBUG_ON_SERIAL_PORT -D SOURCE_DEBUG_ENABLE
#2 run it alone,ok
qemu-system-x86_64.exe -machine pc-q35-2.9 -pflash OVMF32-source-debug.fd -serial stdio 
#3 redirect serial to tcp,it hints "info: QEMU waiting for connection on: disconnected:tcp:::1:1234,server"
qemu-system-x86_64.exe -machine pc-q35-2.9 -pflash OVMF32_source_debug.fd -serial tcp:localhost:1234,server
#4,execute "C:\Program Files (x86)\Intel\Intel(R) UEFI Development Kit Debugger Tool\eXdi.exe" /LaunchWinDbg" with follow settings,but failed connect to qemu.
# error message box"Unable to open TCP address(localhost:1234):No connection could be made because the target machine actively refused it"
[Debug Port]
Channel = TCP
Server = localhost
Port = 1234


I also tried using pipe and com port, all can't connect to qemu,it is very appreciate if anyone could give any baby steps...


# other information:
my windows:win10 x64
QEMU version:2.10
UDK2017
Microsoft (R) Windows Debugger Version 6.12.0002.633 X86(install by default settings)
Intel UEFI Development Debugger Tool 1.5(install by default settings)
