Hi freebsd-current@,
My apologies for so many emails from me. I sent another copy of this
email to freebsd-hackers@.
I have the following patch:

This patch helps me detect the VMD controller, but I am unable to attach
to it.
Therefore, I am not able to attach any PCIe buses that will be used by a
NVMe SSD.
If this patch worked, I would see these devices (as I do in Linux):
10000:e0:1d.0 PCI bridge [0604]: Intel Corporation Tiger Lake-LP PCI
Express Root Port #9 [8086:a0b0] (rev 20) SI
10000:e0:1d.2 PCI bridge [0604]: Intel Corporation Device [8086:a0b2]
(rev 20)
10000:e1:00.0 Non-Volatile memory controller [0108]: Intel Corporation
Device [8086:0975] (rev 03)
10000:e2:00.0 Non-Volatile memory controller [0108]: Intel Corporation
Device [8086:0975]
And therefore a `nvd*` device.
Could a developer please help me with this?
