Several OVMF pages in the TianoCore wiki are somewhat outdated, but I have no permission to edit them. I agree that a discussion would be needed first; see eg. <http://thread.gmane.org/gmane.comp.bios.tianocore.devel/3308/focus=3317>. > I found the instructions on how to enable source level debugging to > be an "exercise left to the reader", at best. > http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=EDK2/Source_Level_Debug. > It seems like source level debugging answer is build with symbols, > and configure a virtual COM port. I actually tried to set that up in April this year, between two virtual machines. I installed "UDK_Debugger_Tool_v1_3_x86_64.bin" in one, and tried to debug OVMF running in the other with it. IIRC I spent days trying to get it to work, but I failed ultimately. The two sides could never really communicate with each other -- maybe it was caused by buggy serial / chardev emulation in then-current RHEL-6 qemu-kvm. I wrote it all up in: http://thread.gmane.org/gmane.comp.bios.tianocore.devel/2585/focus=2598 The first part of that email could be copied as some kind of step-by-step guide into the wiki.

I agree that source level debugging would be very useful. Maybe I should give it another try sometime, with more recent qemu versions (having better / more reliable serial emulation). Thanks!
