This driver implements support for JEDEC JC 42.4 compliant temperature sensors.
|

This driver implements support for JEDEC JC 42.4 compliant temperature sensors,
|
||||
which are used on many DDR3 memory modules for mobile devices and servers. 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.

|
||||
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.
