Hello,
Thank you all for your insights.
You advised me to use the scripts from [1].
I did so following this guide [2] (thank you also for putting it back
up!), with the minor adaptions that I made the script
python3-compatible[3], and applied the patches mentioned in [2]
manually. I assume they failed because they could only be applied to
older versions of the files to be patched.
In particular, I added the line DebugPkg/GdbSyms/GdbSyms.inf right below
line OvmfPkg/PlatformDxe/Platform.inf in line 830 of the vUDK2018
release. That makes sense, right?
The guide looks promising; I think this would give me everything I need.
However I ran into a problem when executing
(gdb) reload-uefi -o
./Build/OvmfX64/DEBUG_GCC5/X64/DebugPkg/GdbSyms/GdbSyms/DEBUG/GdbSyms.dll
gdb complained:
Python Exception <class 'gdb.error'> No type named
EFI_SYSTEM_TABLE_POINTER.:
Error occurred in Python command: No type named
EFI_SYSTEM_TABLE_POINTER.
The EFI_SYSTEM_TABLE_POINTER is defined in
[WORKSPACE]/MdeModulePkg/Core/Dxe/Misc/DebugImageInfo.c, so I'm guessing
I lack that file respectively its corresponding module.
I compiled OVMF with nice OvmfPkg/build.sh -a X64 -n $(getconf
_NPROCESSORS_ONLN).
If you could tell me whether my guess make sense and how I would include
[WORKSPACE]/MdeModulePkg/Core/Dxe/Misc/DebugImageInfo.c, that would be
great.
Kind regards,
Johannes
