Problem reading vitals from Gigabyte H77-DH3H

[Derek Kulinski]

Hello everyone,

I'm unable to read temperature Gigabyte H77-DH3H motherboard. Is that
motherboard supported or am I doing it incorrectly?

When trying to access hw.acpi.thermal everything appears to be ok, but
it is not, the system always returns 27,8C and 29,8C which fooled me
initially - the values never change.

Here is output:
[chinatsu]:/root# sysctl hw.acpi.thermal
hw.acpi.thermal.min_runtime: 0
hw.acpi.thermal.polling_rate: 10
hw.acpi.thermal.user_override: 0
hw.acpi.thermal.tz0.temperature: 27,8C
hw.acpi.thermal.tz0.active: 2
hw.acpi.thermal.tz0.passive_cooling: 0

hw.acpi.thermal.tz1._TC1: 1
hw.acpi.thermal.tz1._TC2: 5
hw.acpi.thermal.tz1._TSP: 10

Since above method fails, I decided to try motherboard monitors in
ports. It seems that almost all of them rely on /dev/smb device.

After loading smb and ichsmb (seems like ichsmb is the only driver
that causes /dev/smb0) any access to /dev/smb0 returns "Device
not configured". For example:

[chinatsu]:/root# lmmon
IOCTL: Device not configured

Similarly mbmon fails:
[chinatsu]:/root# mbmon -V
No VIA686 HWM available!!
InitMBInfo: No error: 0
Exit 1
[chinatsu]:/root# mbmon -S
No SMBus HWM available!!
InitMBInfo: No error: 0
Exit 1
[chinatsu]:/root# mbmon -I
No ISA-IO HWM available!!
InitMBInfo: No error: 0
Exit 1
[chinatsu]:/root# mbmon -A
InitMBInfo: No error: 0
This program needs "setuid root"!!
Exit 1

Here's output of pciconf:
