I hope that those chipsets are kind of generic things, that are compatible with modern ones like my Z68. It goes without saying that SOME of modern MB, supporting Intel Core(tm) CPUs are still supported by mbmon - it shows state of MB (not CPU) thermal sensor, for example. I can't give you exact models, but I can give it after some days (need to ask). >> ššDoes it means that it is no way to read temperature sensors on >> ššmotherboard? > šWell, it depends. š:-) > > šI'm not at all familiar with your particular processor/motherboard, so I > šcan only offer some rather limited advice that may steer you in the > šright direction for further exploration. šThere are a number of devices > šyou can enable in your kernel config that may provide some of what > šyou're looking for. > > šHere, on my amd64 box, for instance, "device amdtemp", along with > š"device cpuctl" and "device cpufreq" makes the following dev.cpu.* > šsysctls available, which are one way to (manually) monitor your > šsystem. šAs you can see below, this provides information on CPU > štemperature and frequency. > > š# sysctl dev.cpu > šdev.cpu.0.%desc: ACPI CPU > šdev.cpu.0.%driver: cpu > šdev.cpu.0.%location: handle=\_PR_.P001 > šdev.cpu.0.%pnpinfo: _HID=none _UID=0 > šdev.cpu.0.%parent: acpi0 > šdev.cpu.0.temperature: 47.0C > šdev.cpu.0.freq: 2200 > šdev.cpu.0.freq_levels: 2200/23500 1100/14280 > šdev.cpu.0.cx_supported: C1/0 > šdev.cpu.0.cx_lowest: C1 > šdev.cpu.0.cx_usage: 100.00% last 1931us > šdev.cpu.1.%desc: ACPI CPU > šdev.cpu.1.%driver: cpu > šdev.cpu.1.%location: handle=\_PR_.P002 > šdev.cpu.1.%pnpinfo: _HID=none _UID=0 > šdev.cpu.1.%parent: acpi0 > šdev.cpu.1.temperature: 47.0C > šdev.cpu.1.cx_supported: C1/0 > šdev.cpu.1.cx_lowest: C1 > šdev.cpu.1.cx_usage: 100.00% last 4658us > šdev.cpu.2.%desc: ACPI CPU > šdev.cpu.2.%driver: cpu > šdev.cpu.2.%location: handle=\_PR_.P003 > šdev.cpu.2.%pnpinfo: _HID=none _UID=0 > šdev.cpu.2.%parent: acpi0 > šdev.cpu.2.temperature: 47.0C > šdev.cpu.2.cx_supported: C1/0 > šdev.cpu.2.cx_lowest: C1 > šdev.cpu.2.cx_usage: 100.00% last 3551us > šdev.cpu.3.%desc: ACPI CPU > šdev.cpu.3.%driver: cpu > šdev.cpu.3.%location: handle=\_PR_.P004 > šdev.cpu.3.%pnpinfo: _HID=none _UID=0 > šdev.cpu.3.%parent: acpi0 > šdev.cpu.3.temperature: 47.0C > šdev.cpu.3.cx_supported: C1/0 > šdev.cpu.3.cx_lowest: C1 > šdev.cpu.3.cx_usage: 100.00% last 4943us As I already say, "coretemp works fine" - I could read CPU thermal sensors with šdev.cpu.#CORE_ID.temperature sysctl after I added "coretemp" device into my kernel. Problem is to read MB sensors, like "chasis (system) temperature", fans RPM, voltages and so on. Now, with smbios device enabled, it still doesn't work the perfect way: # mbmon -V No VIA686 HWM available!! InitMBInfo: Unknown error: 0 # mbmon -S No SMBus HWM available!!
