bhyve: failed to initialize MSI for PCI

[aragats]

I'm trying to passthru a PCIe DAQ card in FreeBSD 13.3-RELEASE:

# pciconf -lbcv | grep -A8 ppt
ppt0@pci0:3:0:0:        class=0x118000 rev=0x02 hdr=0x00 vendor=0x1402 device=0x4660 subvendor=0x165d subdevice=0x1602
    vendor     = 'Meilhaus Electronic GmbH'
    device     = 'ME-4660'
    class      = dasp
    bar   [14] = type I/O Port, range 32, base 0xe200, size 128, enabled
    bar   [18] = type I/O Port, range 32, base 0xe100, size 256, enabled
    bar   [1c] = type I/O Port, range 32, base 0xe280, size 16, enabled
    bar   [20] = type Memory, range 32, base 0xef200000, size 8192, enabled
    bar   [24] = type I/O Port, range 32, base 0xe000, size 256, enabled

However, it doesn't work, and the message about missing file is disappointing:

# bhyve -c 4,sockets=1,cores=4 -S -H -w \
     ....
      -s 11,passthru,ppt0 \
     ....
bhyve: failed to initialize MSI for PCI 3/0/0
Device emulation initialization error: No such file or directory

I also tried providing DAQ's firmware file with rom=me4600.bin with no effect.
What am I missing?...

According to the wiki the PCI device and driver must support MSI/MSI-x interrupts to be able to use passthru: https://wiki.freebsd.org/bhyve/pci_passthru.
Are you sure your device supports them?

Thanks, I missed that, the output of pciconf (above) doesn't reveal anything related to MSI...
The error message is disappointing though.

The error message is disappointing though.

What do you mean by that?

As in it's not helpful because it doesn't say what file is missing? Or is there something else about the message?

There is no missing file. The first part is OK.
