Re: Monitoring temperature with acpi (sysctls)

John Baldwin ?????:
If ACPI doesn't include the sysctl's that's due to your BIOS, not FreeBSD.
You can verify by doing an acpidump and seeing if you have any thermal
zones listed in your ASL.
What if there is a thermal zone, but sysctl returns meaningless numbers?

router# sysctl hw.acpi.thermal
hw.acpi.thermal.min_runtime: 0
hw.acpi.thermal.polling_rate: 10
hw.acpi.thermal.tz0.temperature: -257.-1C
hw.acpi.thermal.tz0.active: -1
hw.acpi.thermal.tz0.passive_cooling: 1
hw.acpi.thermal.tz0.thermal_flags: 0
hw.acpi.thermal.tz0._PSV: 50.0C
hw.acpi.thermal.tz0._HOT: -1
hw.acpi.thermal.tz0._CRT: 60.0C
hw.acpi.thermal.tz0._ACx: 50.0C -1 -1 -1 -1 -1 -1 -1 -1 -1

If I understand it correctly, the current temperature is -257C, or 16 degrees from absolute zero.
Motherboard is Via MS8000.
