For that part of the problem I just discovered something that might be a
hint on the cause, there is no governor set for the thermal zones:
/sys/devices/virtual/thermal/thermal_zone0/policy : (null)
/sys/devices/virtual/thermal/thermal_zone1/policy : (null)
/sys/devices/virtual/thermal/thermal_zone2/policy : (null)
/sys/devices/virtual/thermal/thermal_zone3/policy : (null)
/sys/devices/virtual/thermal/thermal_zone4/policy : (null)
to my understanding this policies should default default to the
CONFIG_THERMAL_DEFAULT_GOV_*
configured in the kernel. But it is always (null) for me. And
something like
# echo fair_share >/sys/devices/virtual/thermal/thermal_zone0/policy
does not work either.
Or is this expected behavior?
cheers
