Running a recent CURRENT (FreeBSD 12.0-CURRENT #11 r305903: Sat Sep 17 20:30:19 CEST
2016) on a PCengines APU 2C4, I see no driver adapted to the SMBus of the system,
although I have the driver statically linked into the kernel via
[...]
# System Management Bus
device smbus
device smb # SMB generic I/O device driver
device ichsmb # Intel ICH SMBus controller driver
device amdsmb # AMD-8111 SMBus 2.0 controller driver
device iicsmb #
device iicbus
device iicbb
device iic
device ic
[...]
pciconf -lvbp shows up this message:
[...]
none1@pci0:0:20:0: class=0x0c0500 card=0x780b1022 chip=0x780b1022 rev=0x42 hdr=0x00
vendor = 'Advanced Micro Devices, Inc. [AMD]'
device = 'FCH SMBus Controller'
class = serial bus
subclass = SMBus
So, I guess CURRENT doesn't have a driver covering this type of system? Or do I miss
something here?
I also see a very strange, mysterious and interesting feature, also not attached with a
driver:
none0@pci0:0:8:0: class=0x108000 card=0x15371022 chip=0x15371022 rev=0x00 hdr=0x00

cap 08[5c] = HT MSI fixed address window enabled at 0xfee00000
cap 01[60] = powerspec 3 supports D0 D3 current D0
Encrypt/decrypt? What is this?
Thanks for your patience and enlighting me,
Oliver
