I tried both tools on three different platforms, on all three, accessing an=
y information
regarding temperatures, voltage, fan speed via SMB failed on FreeBSD 11.0-C=
URRENT/amd64.
The three platforms are:
ICH10:
ichsmb0: <Intel 82801JI (ICH10) SMBus controller> port 0x400-0x41f mem
0xfbfff400-0xfbfff4ff irq 18 at device 31.3 on pci0 smbus0: <System Managem=
ent Bus> on
ichsmb0 smb0: <SMBus generic I/O> on smbus0
MCP Patsburg (LGA2011 box):
ichsmb0: <Intel Patsburg SMBus controller> port 0xf000-0xf01f mem
0x380ffff04000-0x380ffff040ff irq 18 at device 31.3 on pci0 smbus0: <System=
Management
Bus> on ichsmb0 smb0: <SMBus generic I/O> on smbus0
MCP Pather Point (LGA1155):
ichsmb0: <Intel Panther Point SMBus controller> port 0xf040-0xf05f mem
0xf7f15000-0xf7f150ff irq 18 at device 31.3 on pci0 smbus0: <System Managem=
ent Bus> on
ichsmb0 smb0: <SMBus generic I/O> on smbus0
Acces to system informations of xmbmon or healthd is only possible via -I/I=
SA bus.
Attempts to connect via configured /dev/smb0 device ends up with=20
ioctl(SMB_READB): Device not configured
InitMBInfo: Device not configured
