      That device is already supported in 25.07.1. Check the IDs in the diff.

        @stephenw10 - Any ideas?
        As far as I know, Netgate pushed for this development in FreeBSD.
        I can't really find anything about this on FreeBSD channels.

        PS:

          Hmm, no logs showing the driver trying to attach?

          It could be the driver itself doesn't support the virtual function for some reason. That would be unusual though. 🤔

            Nope it is there: https://github.com/pfsense/FreeBSD-src/blob/devel-main/sys/dev/qat/include/common/adf_accel_devices.h#L29

            And it's in 25.07.1. So I'd expect to see it attach or attempt to attach.

                Because the webgui code looks for the device IDs and the C62x is in that list. For some reason the driver isn't attaching to the devices on your hardware, or even trying to attach, so whilst pfSense thinks you have a QAT device there isn't actually one present.

                I've never tried passing through a VF QAT device like that and I suspect that could be causing it. I also don't have any hardware to test it with though.

                Can you pass-through the real PCIe device?

                Can you test bare meta?

                  Can you test bare meta?

                  A little background on the case, this is exactly what this device is:

                  https://i.dell.com/sites/csdocuments/Shared-Content_data-Sheets_Documents/en/virtual-edge-platform-4600-spec-sheet.pdf

                  We have 15 of these in our system, with VersaOS, but the license is extremely expensive and we want to switch to pfSense.

                  What I am currently testing with pfS Plus is equipped with an 8C16T Intel D-2145NT CPU.
                  QAT on these not real PCI devices; they are C62x implemented in the CPU as chipset device(s).

                  Since Dell also sells these with ESXi as base OS opc., we still have a license valid for four years, so I used that.

                  --and the other thing I would like to test before the mature version of "if_pppoe" is this - multi-threaded PPPoE in pfSense
                  https://www.neelc.org/posts/opnsense-pppoe-kvm/

                  Also have a 16C32T D-2187NT version "behind me", which I have already started with a light mfsBSD. So I think pfSense can also run on it as bare metal. I'll try it out soon.

                  This is how it looks in ESXi before you enable SR-IOV - only PCI bridges and the base Chipset device

                  EDIT1: This is a screenshot of the D-2187NT CPU where 3 "ch" QAT is implemented.

                  61f61210-0e09-4c5c-a7c8-cd4aebdcb7ac-image.png

                  After enabling SR-IOV, it creates 16 VFs for each Chipset device (C62x), and only these can be passed to the guest using "pass-thr".

                  9cce2c4d-f1fc-4ef8-94c5-07dd6ad805f4-image.png

                  What you see in the VM PCI list...

                  9401334c-d5fc-420e-944c-d6b1060bb2cd-image.png

                  pfSense also sees this correctly

                  • just doesn't load drivers for them for some reason (?)
                    Perhaps because they are VFs, but they are also listed as PCI devices, so they are present.

                  Cats bury it so they can't see it!

                    So before you enable SR-IOV you can't pass through the PCIe devices directly?

                      Yes, it was, thanks for the train of thought. :)
                      (control plane is needed)

                      Only the pass-thr. the Virtual Functions does not work.

                      • I updated Intel FreeBSD 1.x VIB to the latest version on ESXi.
                      • I revoked all pass-thr. and PCI assignments in ESXi and pfS VM -- & SR-IOV off in ESXi on C62X
                      • After updating VIB, I was able to enable only the pass-thr. of C62x chipset device, which I transferred to the VM as a complete PCI device.

                      Seeing the complete device, pfSense was able to assign a driver to the QAT C62X.

                      D-2145NT CPU only 1 "ch" QAT implemented

                      18cdec9a-fa83-484f-acd9-5e7207d29906-image.png

                      The original goal was not to assign all VFs to pfSense, but with this CPU, it is necessary because there is only one "ch" QAT.

                      For example, D-2187NT CPU has 3 channels (3x16VFs), where other VMs can also get a QAT device if needed.

                      The lesson is that cannot use SR-IOV first, but must need pass-thr. the entire device to the pfS guest.

                      On Linux, for example handles this and explicitly recommends that in case multiple QAT "CHs", - VFs should be symmetrically distributed to the guest(s).

                      D-2187NT offers greater flexibility if you want to run more than just pfSense guests on ESXi, as QAT capability remains available for other VMs.

                      I should note that I am STILL a fan of bare metal pfSense, but there are cases where paravirtualization can help. This is now the case.

                      And honestly, after so many years away, it was good to return to pfSense. It never disappoints. I did skip the PLUS licensing thing (but the TAC was fair), but Netgate is right: counterfeiters MUST be stopped somehow!

                      @stephenw10 - THX 😉
