You can't, thermal zones are read-only at least through the hwmon
interface. If anything can be done, this is through ACPI.

OK, thanks for that clarification. Do you have a tip on how I could go
about to  set it through ACPI?

Who (which program/demon/whatever) is responsible for creating this virtual
device and its settings?

Hi Thomas,

Please don't top-post.

I think it used to be overridable with boot parameters and/or procfs
attributes but I seem to recall this feature was removed from the
kernel some times ago. You'll have to ask the ACPI people for the
current status.

I'm afraid the only possibility left is to customize your DSDT and
override the DSDT with your modified copy at boot time.

The kernel itself is doing it, based on ACPI tables / BIOS information.

Just for reference: I asked at the linux-acpi list and they advised me
to add termal.crt=<value> to the kernel boot paramters, which I did
(<value>™) and it actually sets the temperature of the virtual device.

Now I get:

# acpi -V
Thermal 0: ok, 64.0 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 99.0
degrees C
Thermal 0: trip point 1 switches to mode passive at temperature 105.0
degrees C

and

acpitz-virtual-0
Adapter: Virtual device
temp1:
  temp1_input: 66.000
  temp1_crit: 99.000

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:
  temp1_input: 66.000
  temp1_max: 86.000
  temp1_crit: 100.000
  temp1_crit_alarm: 0.000
Core 0:
  temp2_input: 63.000
  temp2_max: 86.000
  temp2_crit: 100.000
  temp2_crit_alarm: 0.000
Core 1:
  temp3_input: 66.000
  temp3_max: 86.000
  temp3_crit: 100.000
  temp3_crit_alarm: 0.000

pkg-temp-0-virtual-0
Adapter: Virtual device
temp1:
  temp1_input: 67.000


Thanks for your hints,

Thomas
