Some -systems use the sensor to prevent memory overheating by automatically throttling -the memory controller. - -The driver auto-detects the chips listed above, but can be manually instantiated -to support other JC 42.4 compliant chips. - -Example: the following will load the driver for a generic JC 42.4 compliant -temperature sensor at address 0x18 on I2C bus #1:: - - # modprobe jc42 - # echo jc42 0x18 > /sys/bus/i2c/devices/i2c-1/new_device - -A JC 42.4 compliant chip supports a single temperature sensor. Minimum, maximum, -and critical temperature can be configured. There are alarms for high, low, -and critical thresholds. - -There is also an hysteresis to control the thresholds for resetting alarms. -Per JC 42.4 specification, the hysteresis threshold can be configured to 0, 1.5, -3.0, and 6.0 degrees C. Configured hysteresis values will be rounded to those -limits. The chip supports only a single register to configure the hysteresis, -which applies to all limits. This register can be written by writing into -temp1_crit_hyst. Other hysteresis attributes are read-only. - -If the BIOS has configured the sensor for automatic temperature management, it -is likely that it has locked the registers, i.e., that the temperature limits -cannot be changed. - -Sysfs entries -------------- - -======================= =========================================== -temp1_input Temperature (RO) -temp1_min Minimum temperature (RO or RW) -temp1_max Maximum temperature (RO or RW) -temp1_crit Critical high temperature (RO or RW) - -temp1_crit_hyst Critical hysteresis temperature (RO or RW) -temp1_max_hyst Maximum hysteresis temperature (RO) - -temp1_min_alarm Temperature low alarm -temp1_max_alarm Temperature high alarm -temp1_crit_alarm Temperature critical alarm -======================= =========================================== -- cgit v1.2.3-59-g8ed1b
