Duane,
In order to get DEBUG() and ASSERT() macros to show up on a serial port in
QEMU, have you tried setting DEBUG_ON_SERIAL_PORT for the build command for
OVMF?
build -p OvmfPkg\OvmfPkgX64.dsc -D DEBUG_ON_SERIAL_PORT

Subject: Re: [edk2] OVMF networking revisited
(you know we used to run entire operating systems in 512Kb ;) Bumping the RAM
up to 1GB produced no change.
Ok, I see gEfiMdePkgTokenSpaceGuid.PcdDebugPrintErrorLevel in the .dsc and have
added the VERBOSE, SNI Driver, and Boot Manager flags. (also no change)
I looked at your qemu command line - you ran without any network at all. I can
do that as well with the *prebuilt* OVMF.fd (without the network stack). I
however need to use a uEFI image with the network stack installed. I have
never seen a precompiled OVMF.fd with network support in the wild - is there a
lisencing issue with NIC drivers?
And it seems I am unable to build an OVMF.fd with *or without* the uefi network
stack (using VS2008 or GCC44) that does not hang with a blank screen. This is
likely the crux of the matter here - I can't reproduce building the OVMF.fd at
all.
To summarize, I build with:
> build -p OvmfPkg\OvmfPkgX64.dsc
(which compiles correctly on both VS2008 and GCC44 since I have the Intel3.5
e1000 drivers installed in my workspaces), and run with:
$ qemu-system-x86_64 -m 1024 -hda ovmf.disk -monitor stdio -debugcon
file:debug.log
(where bios.bin is symlinked to OVMF.fd) this hangs with a blank screen and no
debug messages.
I'm at edk2 revision 14204
Do you know where I can get an OVMF.fd with a network stack?
