High count of "no driver attached" in dmesg

I've installed FreeBSD 12.1-RELEASE on new hardware (SuperMicro X11 SPM-F + Intel Xeon Silver 4210) and in comparison to older hardware (X9 motherboards from Supermicro, old desktop motherboard from Intel) I have a lot of "no driver attached" messages in dmesg output (full https://www.patpro.net/~patpro/dmesg.txt):

Code: 
pci0: <dasp, performance counters> at device 8.1 (no driver attached)
pci0: <unknown> at device 17.0 (no driver attached)
pci0: <unknown> at device 17.1 (no driver attached)
pci0: <simple comms> at device 22.0 (no driver attached)
pci0: <simple comms> at device 22.1 (no driver attached)
pci0: <simple comms> at device 22.4 (no driver attached)
pci0: <memory> at device 31.2 (no driver attached)
pci0: <serial bus> at device 31.5 (no driver attached)
pci10: <network, ethernet> at device 0.0 (no driver attached)
pci7: <dasp, performance counters> at device 14.0 (no driver attached)
pci7: <dasp, performance counters> at device 15.0 (no driver attached)
pci7: <dasp, performance counters> at device 18.0 (no driver attached)
pci7: <dasp, performance counters> at device 18.1 (no driver attached)
pci7: <dasp, performance counters> at device 21.1 (no driver attached)
pci7: <dasp, performance counters> at device 22.1 (no driver attached)
pci7: <dasp, performance counters> at device 22.5 (no driver attached)

I wonder if it's to be expected. Is there any common fix?
(on the X9 motherboard I've got only one, and none on the Intel desktop motherboard)

Thanks a lot.
 
It appears to me that the kernel isn't aware of these newer devices. If the GENERIC kernel isn't aware of them then you need to submit a bug report. I would also try installing 11.3-RELEASE to verify this isn't unique to 12.x.
 
A installation is not necessary, booting a installation image is sufficient. Besides 11.3-RELEASE you can try 12.1-STABLE and 13.0-CURRENT.
 
Result with 13.0-CURRENT is the same:

Code: 
pci0: <dasp, performance counters> at device 8.1 (no driver attached)
pci0: <unknown> at device 17.0 (no driver attached)
pci0: <unknown> at device 17.1 (no driver attached)
pci0: <simple comms> at device 22.0 (no driver attached)
pci0: <simple comms> at device 22.1 (no driver attached)
pci0: <simple comms> at device 22.4 (no driver attached)
pci0: <memory> at device 31.2 (no driver attached)
pci0: <serial bus> at device 31.5 (no driver attached)
pci10: <network, ethernet> at device 0.0 (no driver attached)
pci7: <dasp, performance counters> at device 14.0 (no driver attached)
pci7: <dasp, performance counters> at device 15.0 (no driver attached)
pci7: <dasp, performance counters> at device 18.0 (no driver attached)
pci7: <dasp, performance counters> at device 18.1 (no driver attached)
pci7: <dasp, performance counters> at device 21.1 (no driver attached)
pci7: <dasp, performance counters> at device 22.1 (no driver attached)
pci7: <dasp, performance counters> at device 22.5 (no driver attached)

pciconf output for 13.0-CURRENT is here: https://patpro.net/~patpro/pciconf-levc.20200307-0.txt
full dmesg -a is here: https://patpro.net/~patpro/dmesg_13.0.txt

I'll try 11.3-RELEASE later but I'm not very optimistic.
 
I wouldn't be either. These are most likely new devices the kernel isn't aware of. That's one of the caveats with using FreeBSD, you need to be a half or a generation behind for driver support.

Click to expand...
You are correct, sir. If you have any unattached drivers with a bootable installation image, it's most likely presently unspported hardware.
 
Well, may be in a year or two FreeBSD will come to fully support this hardware. I guess that could count as an hardware upgrade ;D
 
Look at the description of the devices that have no drivers in your long output: They are various CPU registers (probably performance counters), chipset MROM, management engine, chipset power management, SPI interface, and so on. Look for all the peripherals labelled "none" in the long output. Do you actually need any of those? Can one actually make practical use of any of those on a server? Other than for low-level benchmarking, I don't know what they are useful for.
 
Copy the pciconf output here so as not to lose in the future.
