Hi, With 3.12-rc series, sysfs support for thermal susbsytem (and/or hwmon one) was modified in such a way that sensors utility (current 3.3.4 version with 3.3.4 version of libsensors from lm-sensors package on Debian unstable) does not see the temperature sensor anymore on armada 370 platforms (not tested on others). Additionally, the changes break existing configurations of fancontrol utility, which prevents the fan to be regulated correctly w/o recreating an /etc/fancontrol w/ pwmconfig. Here is what I have on my Armada 370-based system on a 3.11.5: # sensors g762-i2c-0-3e Adapter: mv64xxx_i2c adapter fan1: 2457 RPM (div = 1) armada_thermal-virtual-0 Adapter: Virtual device temp1: +45.7°C And what I get on 3.12-rc6: # sensors g762-i2c-0-3e Adapter: mv64xxx_i2c adapter fan1: 1350 RPM (div = 1) Monitoring what sensors does w/ strace, I started looking at the changes to /sys/class/hwmon/hwmon1/: On 3.11.5: # find /sys/class/hwmon/hwmon1/ /sys/class/hwmon/hwmon1/ /sys/class/hwmon/hwmon1/name /sys/class/hwmon/hwmon1/subsystem /sys/class/hwmon/hwmon1/uevent /sys/class/hwmon/hwmon1/temp1_input On 3.12-rc6: # find /sys/class/hwmon/hwmon1/ /sys/class/hwmon/hwmon1/ /sys/class/hwmon/hwmon1/name /sys/class/hwmon/hwmon1/device /sys/class/hwmon/hwmon1/subsystem /sys/class/hwmon/hwmon1/uevent /sys/class/hwmon/hwmon1/temp1_input # find /sys/class/hwmon/hwmon1/device/ /sys/class/hwmon/hwmon1/device/ /sys/class/hwmon/hwmon1/device/temp /sys/class/hwmon/hwmon1/device/type /sys/class/hwmon/hwmon1/device/hwmon1 /sys/class/hwmon/hwmon1/device/hwmon1/name /sys/class/hwmon/hwmon1/device/hwmon1/device /sys/class/hwmon/hwmon1/device/hwmon1/subsystem /sys/class/hwmon/hwmon1/device/hwmon1/uevent /sys/class/hwmon/hwmon1/device/hwmon1/temp1_input /sys/class/hwmon/hwmon1/device/subsystem /sys/class/hwmon/hwmon1/device/policy /sys/class/hwmon/hwmon1/device/uevent /sys/class/hwmon/hwmon1/device/passive Is that expected? As for sensors, it *seems* to be bothered to find a device/ folder in /sys/class/hwmon/hwmon1/ w/o no name entry in it. Cheers, a+ ps: I can test if this is the same on kirkwood if there is a need. _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
