Description
|
||||
-----------
|
||||
|
||||
The chips supported by this driver are very similar. The Maxim MAX1617 is
|
||||
the oldest; it has the problem that it is not very well detectable. The
|
||||
MAX1617A solves that. The ADM1021 is a straight clone of the MAX1617A.
|
||||
Ditto for the THMC10. From here on, we will refer to all these chips as
|
||||
ADM1021-clones.
|
||||
|
||||
The ADM1021 and MAX1617A reports a die code, which is a sort of revision
|
||||
code. This can help us pinpoint problems; it is not very useful
|
||||
otherwise.
|
||||
|
||||
ADM1021-clones implement two temperature sensors. One of them is internal,
|
||||
and measures the temperature of the chip itself; the other is external and
|
||||
is realised in the form of a transistor-like device. A special alarm
|
||||
indicates whether the remote sensor is connected.
|
||||
|
||||
Each sensor has its own low and high limits. When they are crossed, the
|
||||
corresponding alarm is set and remains on as long as the temperature stays
|
||||
out of range. Temperatures are measured in degrees Celsius. Measurements
|
||||
are possible between -65 and +127 degrees, with a resolution of one degree.
|
||||
|
||||
If an alarm triggers, it will remain triggered until the hardware register
|
||||
is read at least once. This means that the cause for the alarm may already
|
||||
have disappeared!
|
||||
|
||||
This driver only updates its values each 1.5 seconds; reading it more often
|
||||
will do no harm, but will return 'old' values. It is possible to make
|
||||
ADM1021-clones do faster measurements, but there is really no good reason
|

for that.

Netburst-based Xeon support
|
||||
---------------------------
|
||||
|
||||
Some Xeon processors based on the Netburst (early Pentium 4, from 2001 to
|
||||
2003) microarchitecture had real MAX1617, ADM1021, or compatible chips
|
||||
within them, with two temperature sensors. Other Xeon processors of this
|
||||
era (with 400 MHz FSB) had chips with only one temperature sensor.
|
||||
|
||||
If you have such an old Xeon, and you get two valid temperatures when
|
||||
loading the adm1021 module, then things are good.
|
||||
|
||||
If nothing happens when loading the adm1021 module, and you are certain
|
||||
that your specific Xeon processor model includes compatible sensors, you
|
||||
will have to explicitly instantiate the sensor chips from user-space. See
|
||||
method 4 in Documentation/i2c/instantiating-devices.rst. Possible slave
|
||||
addresses are 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e. It is likely that
|
||||
only temp2 will be correct and temp1 will have to be ignored.
|
||||
|
||||
Previous generations of the Xeon processor (based on Pentium II/III)
|
||||
didn't have these sensors. Next generations of Xeon processors (533 MHz
|
||||
FSB and faster) lost them, until the Core-based generation which
|
||||
introduced integrated digital thermal sensors. These are supported by
|
||||
the coretemp driver.

PEC Support

-----------

PEC is not implemented.

When reading a register value, the PEC byte is computed and sent by the chip.

PEC on word data transaction respresents a signifcant increase in bandwitdh

usage (+33% for both write and reads) in normal conditions.

Since this operation implies there will be an extra delay to each

transaction, PEC can be disabled or enabled through sysfs.

Just write 1 to the "pec" file for enabling PEC and 0 for disabling it.

Description
|
||||
-----------
|
||||
|
||||
This driver implements support for SPD5118 (JEDEC JESD300) compliant temperature
|
||||
sensors, which are used on many DDR5 memory modules. Some systems use the sensor
|
||||
to prevent memory overheating by automatically throttling the memory controller.
|
||||
|
||||
The driver auto-detects SPD5118 compliant chips, but can also be instantiated
|
||||
using devicetree/firmware nodes.
|
||||
|
||||
A SPD5118 compliant chip supports a single temperature sensor. Critical minimum,
|
||||
minimum, maximum, and critical temperature can be configured. There are alarms
|
||||
for low critical, low, high, and critical thresholds.
|
||||

||||

temp1_input Temperature (RO)
|

temp1_lcrit Low critical high temperature (RW)
|

temp1_lcrit_alarm Temperature low critical alarm
|

temp1_min_alarm Temperature low alarm
|

temp1_max_alarm Temperature high alarm
|

temp1_crit_alarm Temperature critical alarm
|
||||
======================= ==================================
|
||||
|
||||
Alarm attributes are sticky until read and will be cleared afterwards
|
||||
unless the alarm condition still applies.
|
||||
|
||||
|
||||
SPD (Serial Presence Detect) support
|
||||
------------------------------------
|
||||
|
||||
The driver also supports reading the SPD NVRAM on SPD5118 compatible chips.
|
||||
SPD data is available from the 'eeprom' binary attribute file attached to the
|
||||
chip's I2C device.
