Monitoring temperature with acpi (sysctls)

[Mike Jakubik]

Well, here are the patch results.

The controller is detected:

ichsmb0: <Intel 82801GB (ICH7) SMBus controller> port 0x1100-0x111f irq 
19 at device 31.3 on pci0
ichsmb0: [GIANT-LOCKED]
smbus0: <System Management Bus> on ichsmb0
smb0: <SMBus generic I/O> on smbus0

However communication does not seem to work:

# smbmsg -p
Probing for devices on /dev/smb0:
Device @0x30: rw
Device @0x32: rw
^C

ichsmb0: device timeout, status=0x41
ichsmb0: device timeout, status=0x41
ichsmb0: device timeout, status=0x41

I also tried running mbmon using SMB, however this is the result:

# mbmon -S
No SMBus HWM available!!
InitMBInfo: Unknown error: 0

Without any options, i get bogus temp values:

# mbmon

Temp.= 208.0,  0.0,  0.0; Rot.=    0,    0,    0
Vcore = 3.62, 3.62; Volt. = 3.62, 5.21, 11.80,   1.13,  2.09
