Oh, OK. Basically, I'm interested in looking at the sources
(specifically, the SMBIOS code :) ) to try and develop my own
sense of what might be the most agreeable way forward for my
QEMU smbios patches... That way, I'd actually have a (hopefully
somewhat intelligent) position of my own to support :) :)
For that, ideally, I'd like to clone a git repo (and pull once
every few days to stay on top of things). Looks like the top-level
upstream one doesn't have your smbios code, so would there be a
"mid-stream" (for the lack of a better term) git repo you have
that I can clone and hack against for the smbios stuff ?
I ask because yesterday was the first time I started really paying
attention to edk2 and ovmf, and I don't yet have a sense of how fast
the "state of the universe" would run away from me while my back is
turned, i.e. how fast a point-in-time snapshot of e.g. Gerd or Paolo's
RPMs would become stale... Extracting and patching source code from
RPMs is OK once or twice, but I imagine will be much less fun than
"git pull" once it gets repetitive :D

Good to know (-bios == read-only, -pflash == writable) :)
I'm really only in it for testing smbios interactions with qemu though,
at least at this stage... :)
Thanks a ton,
