Help me troubleshoot PCI passthrough

[RefreshingBeverage]

Hi

I recently shutdown my ESXi server, since the only VM I had running, was a pfSense firewall.
... However I still need said firewall. And my NAS does have a bunch of NICs. So why not spin up a VM running pfSense on it! Makes perfect sense!

Now here comes my challenge: I want to passthough some NICs to my VM, but doing a prerequisite check to see if I'm even able to passthough my PCI devices I get less than desirable results:
root@truenas[~]# acpidump -t | grep DMAR root@truenas[~]#

According to this video and the freeBSD wiki:

Now, I don't judge you for assuming that I'm a dumb-dumb.
But let me assure you: I have been into my UEFI settings and enabled IOMMU and SVM. But there's still no DMAR table to see.

So I'm hoping someone more adept than me, can help me troubleshoot this issue.

My config:
Mobo: Asus - ROG Strix B550-F GAMING (non-WiFi)
CPU: AMD - Ryzen R5-5600X
OS: TrueNAS Core - 12.0-U7

Stuff I've tried so far.

• Attempted to see DMAR table, but in Ubuntu.
• Flashed UEFI firmware to a much older version.
• Tried fiddling with UEFI settings (loaded defaults, enabled/disabled IOMMU and SVM)
• Tried issuing a "pciconf -lcv | less" command in shell, but I don't know what I am looking at...
  root@truenas[~]# pciconf -lcv | less
vendor = 'Advanced Micro Devices, Inc. [AMD]' device = 'Starship/Matisse Root Complex' class = bridge subclass = HOST-PCI

vendor = 'Advanced Micro Devices, Inc. [AMD]' device = 'Starship/Matisse IOMMU' class = base peripheral subclass = IOMMU

vendor = 'Advanced Micro Devices, Inc. [AMD]' device = 'Starship/Matisse PCIe Dummy Host Bridge' class = bridge subclass = HOST-PCI

Man, did you get anywhere with this? Still a problem in 2.6

 

[homer27081990]

I have the very same issue.
Setup is:
ProLiant DL380P Gen 8.1 - 4 Port Broadcomm NIC -> TrueNAS BHyve - Passthrough 3 out of 4 ports (3/0/1 3/0/2 3/0/3) -> PfSense

And in PfSense:

Can someone at least rule out this being a TrueNAS problem?

I should also point out that I have a virtual NIC from a TrueNAS bridge with no NICs attached, that is the NIC that is showing up in boot (vtnet0).

That video resembles @Yorick ... perhaps he can help.

Thank you very much for taking the time to comment. I dug a little deeper and I believe I am ready to start a new thread, because although the symptoms are the same, the underlying manifestation of the problem (specific errors and such) seem to be vastly different. Thank you again.
