I have the following PCIe card on a host running 11.1-RELEASE:
| ppt0@pci0:5:0:0: class=0x078000 card=0x00011b74 chip=0x08101b74
rev=0x14 hdr=0x00
| vendor = 'OpenVox Communication Co. Ltd.'
| class = simple comms
it doesn't support MSI according to `pciconf -lbc`:
| ppt0@pci0:5:0:0: class=0x078000 card=0x00011b74 chip=0x08101b74
rev=0x14 hdr=0x00
| bar [10] = type Memory, range 32, base 0xdfe00000, size 524288,
enabled
Trying to pass this card to a guest using `vm-bhyve` gives me the
following in `bhyve.log`:
| bhyve: failed to initialize MSI for PCI 5/0/0
and this in `vm-byve.log`:
| [bhyve options: -c 2 -m 2G -Hwl
bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd -U
9f2546f5-5464-11e8-8b52-d05099c0f275 -S]
| [bhyve devices: -s 0,hostbridge -s 31,lpc -s

5:0,virtio-net,tap2,mac=58:9c:fc:00:d7:6b -s 6:0,passthru,5/0/0 -s
7:0,fbuf,tcp=0.0.0.0:5900]
| [bhyve console: -l com1,/dev/nmdm0A]
| [bhyve iso device: -s 3:0,ahci-cd,/var/vm/.config/null.iso]
| starting bhyve (run 1)
| bhyve exited with status 1
Now .. is it actually possible to pass such a device to a bhyve guest?
From the code comment here:
<https://github.com/freebsd/freebsd/blob/master/usr.sbin/bhyve/pci_passthru.c#L257>
I assumed MSI would be "emulated" if necessary?
TIA, Felix
