ACPI thermal procfs I/F removed from kernel 2.6.37

[André Ventura]

Binary package hint: sensors-applet

From the 2.6.36 changelog (http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.36):

Mark the ACPI thermal procfs I/F deprecated, because /sys/class/thermal/ is already available and has been working for years w/o any problem.
The ACPI thermal procfs I/F will be removed in 2.6.37.

Looks like the acpi plugin will need to be ported to use the thermal zone stuff from sysfs - http://lwn.net/Articles/268958/

Thanks for reporting this, unfortunately I don't have a machine which supports acpi thermal zones so it will be hard to do the port myself and ensure it is correct, but I will see what I can do - patches are welcome :)

Well, I made this patch, when I reported the bug, but it didn't work, so I didn't upload. Here it goes, nevertheless. :)

[Hernando Torque (htorque)]

Can't work because '/sys/class/thermal' contains only symlinks, which 'lib/sensors-applet-plugin.c' doesn't care about.

Here's another patch. Works for me, unfortunately the sensors are now labeled "thermal_zone*" which is pretty useless as I don't know which of the six thermal zones I should keep a look at.

[Alex Murray (alexmurray)]

The latest lm-sensors (aka libsensors) apparently support reading the acpi thermal zone temperatures so we can probably just remove the acpi plugin from sensors-applet to fix this - can anyone confirm if this is the case? i.e. if the libsensors plugin shows these temperatures?

[Alex Murray (alexmurray)]

These will probably just show up as tempX under libsensors.
