Simple ThinkPad fan control daemon

simpfand's Issues

BASE_LVL cannot be 0

On low temperature, fan should be off. I tried to set BASE_LVL = 0 but that lead to a segfault on startup.

simpfand cannot read temperature input

simpfand[13184]: fan control started
simpfand[13184]: error: could not read temperature input
simpfand[13184]: fan level set to auto, exiting

kernel 4.0.4-2: error: could not find temp path

While using Kernel 4.0.4 on Arch Linux, simpfand doesn't work any more.

found temp path: /proc/acpi/ibm/fan

For some reason, today my laptop's hwmon is available through /sys/devices/platform/coretemp.0/hwmon/hwmon8/temp1_input, I discovered that simpfand was not working any more because my laptop was very hot, and after investigating, turns out that it was broken but not that much I'd have noticed.

I patched the sources to add hwmon8 to the list of possible paths, but I don't think it is a viable solution, it should probably be doing things like opendir /sys/devices/platform/coretemp.0/hwmon and look at what's in there instead of adding more paths.

And there is the strangen thing is that simpfand was not failing to start after not finding the temp path, it somehow ended up defaulting to /proc/acpi/ibm/fan, which does exist but does not contain what was expected, leading to strange logs like this:
