Title:
kidle_inject overly onerous, fans never used on MacBookPro12,1
Status in linux package in Ubuntu:
Confirmed
Bug description:
At least since upgrading to Yakkey, my MacBookPro12,1 (13", 2015)
seems to respond to increased system heat using only kidle_inject, and
not the built-in fan. kidle_inject with kick in rather quickly,
especially with the Australian summer starting to be felt, and will
render the system near useless.
Doing some investigation, it appears that no fan is registered as a
cooling device:
> mjg@payens:~$ grep . /sys/class/thermal/cooling_device*/type
> /sys/class/thermal/cooling_device0/type:Processor
> /sys/class/thermal/cooling_device1/type:Processor
> /sys/class/thermal/cooling_device2/type:Processor
> /sys/class/thermal/cooling_device3/type:Processor
> /sys/class/thermal/cooling_device4/type:intel_powerclamp
Even though one is picked up by applesmc:
> Nov 08 10:08:56 payens kernel: applesmc: key=670 fan=1 temp=35
index=34 acc=0 lux=2 kbd=1
The fan seems to be physically in good condition, I tested it out
using the following:
> root@payens:~# echo 6000 >
/sys/devices/platform/applesmc.768/fan1_min
Which started it blowing a lot of warm air out.
