Are any external/USB graphics adapters supported?
-
Hmm. Sounds like you didn't get the right hardware for the job at-hand.
-
IPMI ports seem rather obscure a requirement. I want to plug in an external graphics adapter to have full graphics output on demand; IPMI is not the right hardware for the job at-hand.
This blog post shows a commit in FreeBSD that adds support for USB DisplayLink adapters; how would I be able to map a Free BSD SVN revision to a BSD release? Is this in pfSense 2.3 / FreeBSD 10.3 already?

An external graphics adapter is actually a pretty obscure requirement.
IPMI in a rack system is pretty ubiquitous. Else serial console. Else an actual VGA/KVM ports.
You screwed the pooch on this purchase. Sorry.

You picked a gamer board designed around the ability to install 3 gpus and want to run it without a gpu… At this point the best solution is to give up the idea of gps and use the onboard serial port as a console. (Gps over serial is pretty lousy anyway.) Or if you're still within the return window, pick a more optimal motherboard.
-
I picked one of the few motherboards that met my requirements, of which 'gamer board' was not one:
- Supports Registered ECC memory
- Has at least 4 RAM slots so I can run 4x8GB instead of 2x16GB
- Is Micro ATX or Mini ITX to fit in the 1U chassis I selected
- Takes fairly modern CPUs (2011-3, AM4, or newer, but Ryzen ECC support only theoretical at this point)
- Has at least one M.2 slot for an on-board SSD

None of these options have IPMI ports.
Why is GPS over serial lousy? It looks fairly legit in this video, with the PPS signal provided on a separate line (DCD) generating an interrupt.

Here's his result after adding the GPS over serial.

In either case, no I do not want IPMI ports, nor does that solve what I asked.
No I do not want to abandon GPS over serial, or add another serial port, as it also does not solve what I asked.
I want on-demand graphics to a monitor over USB, from pfSense/FreeBSD. Does anyone know of any DisplayLink adapters that are compatible, or have gotten this working? This has been fairly well supported in Linux kernels for ~6+ years.

Try it and see.

Indeed; how helpful.

You're in territory here where nobody can give a first-hand experience "yes" or '"no" answer to your specific question. Hence, "try it and see."
Quick Google search brings up this: http://www.phoronix.com/scan.php?page=news_item&px=FreeBSD-DisplayLink-Support
Looks promising.
-
Indeed; it links to an SVN Commit from 2015.03.07, which makes it unclear as to whether it is part of the Free BSD 10.3 release 2016.04.04.
This is also promising, but it doesn't seem to be present in 10.3, only 11+

Should be in pfSense 2.4 snapshots:
https://github.com/pfsense/FreeBSD-src/blob/releng/11.0/sys/dev/usb/video/udl.cNo idea about making that the primary console though. Some hackery required I would think if it works at all.

Yeah, I plan on starting with a 2.4 snapshot. I'll try with a couple DisplayLink adapters I have already, but I will likely have to complete the initial setup via the serial port or a temporary graphics card.

If you don't care, or you don't know the answer, then your reply is not only pointless but also demonstrating that you do care in some way (at least sufficiently enough to comment).

You chose a weird set of requirements, decided to run a dedicated firewall OS on top of it, and want to do something unusual with it. I assume this is for a home lab, so just experiment until you find something that works for you. Or just run linux. With the overkill in CPU & memory you could virtualize pfsense, still get perfectly acceptable performance, and have lots of room left over for other VMs.

What was 'weird' about the requirements, exactly?
Modernish CPU, Micro ATX to fit in a small 1U chassis, ECC, 4 slots for RAM all seem fairly reasonable, and I simply prefer M.2 for a more elegant storage solution rather than a separate 2.5" drive with associated SATA and Power cables. I'm reading now that some consumer Ryzen motherboards support unbuffered ECC RAM and have integrated graphics, so perhaps that would have been easier but the ECC support is spotty at best.
Though it seems fairly 'unusual' perhaps, I think it would be quite useful to run without a graphics card and only plug in a USB based graphics adapter for initial setup and troubleshooting.
-
What was 'weird' about the requirements, exactly?
The requirement to support some whacky USB GPU? Guess how many firewalls out there have USB-based graphics chip. So, here's a suggestion: get the most shitty PCIe passively cooled GPU you can get your hands on from some dumpster, stick it into one of those completely unused PCIe slots and move on.
-
I think that was plan A but limited space for expansions cards in the case makes it a problem.
You might be able to fit a PCIe serial port card in directly?
Since you already have the display link adapters you might as well try them. It would be interesting to see the results but I would expect significant problems. :-\

Stop trying to get a GPU in there. The console over video out looks exactly the same as the serial console. Use a simple USB-Serial adapter (one end has USB, you stick that in to the firewall, the other end has RS232) and be done. If you want to do it "right", you might as well put the serial adapter in use with that GPS unit, and use the 'real' serial port for the console.
