Description
|
||||
-----------
|
||||
|
||||
This driver supports reporting the temperature of disk and solid state
|
||||
drives with temperature sensors.
|
||||
|
||||
If supported, it uses the ATA SCT Command Transport feature to read
|
||||
the current drive temperature and, if available, temperature limits
|
||||
as well as historic minimum and maximum temperatures. If SCT Command
|
||||
Transport is not supported, the driver uses SMART attributes to read
|
||||
the drive temperature.
|
||||
|
||||
|
||||
Sysfs entries
|
||||
-------------
|
||||
|
||||
Only the temp1_input attribute is always available. Other attributes are
|
||||
available only if reported by the drive. All temperatures are reported in
|
||||
milli-degrees Celsius.
|
||||
|
||||
======================= =====================================================
|
||||

temp1_min Minimum recommended continuous operating limit
|
||||
temp1_max Maximum recommended continuous operating temperature
|
||||
temp1_crit Maximum temperature limit. Operating the device above
|

Description

-----------
|
||||
|
||||
This driver implements support for Maxim MAX31730.
|
||||
|
||||
The MAX31730 temperature sensor monitors its own temperature and the
|
||||
temperatures of three external diode-connected transistors. The operating
|
||||
supply voltage is from 3.0V to 3.6V. Resistance cancellation compensates
|
||||
for high series resistance in circuit-board traces and the external thermal
|
||||
diode, while beta compensation corrects for temperature-measurement
|
||||
errors due to low-beta sensing transistors.

Description
|
||||
-----------
|
||||
|
||||
This driver implements support for Infineon Multi-phase XDPE122 family
|
||||
dual loop voltage regulators.
|
||||
The family includes XDPE12284 and XDPE12254 devices.
|
||||
The devices from this family complaint with:
|
||||
- Intel VR13 and VR13HC rev 1.3, IMVP8 rev 1.2 and IMPVP9 rev 1.3 DC-DC
|
||||
converter specification.
|
||||
- Intel SVID rev 1.9. protocol.
|
||||
- PMBus rev 1.3 interface.
|
||||
|
||||
Devices support linear format for reading input voltage, input and output current,
|
||||
input and output power and temperature.
|
||||
Device supports VID format for reading output voltage. The below modes are
|
||||
supported:
|
||||
- VR12.0 mode, 5-mV DAC - 0x01.
|
||||
- VR12.5 mode, 10-mV DAC - 0x02.
|
||||
- IMVP9 mode, 5-mV DAC - 0x03.
|
||||
- AMD mode 6.25mV - 0x10.
|
||||
|
||||
Devices support two pages for telemetry.
|
||||
|
||||
The driver provides for current: input, maximum and critical thresholds
|
||||
and maximum and critical alarms. Critical thresholds and critical alarm are
|
||||
supported only for current output.
|
||||
The driver exports the following attributes for via the sysfs files, where
|
||||
indexes 1, 2 are for "iin" and 3, 4 for "iout":
|
||||
|
||||
**curr[3-4]_crit**

||||
|
||||
**curr[1-4]_max**
|
||||
|
||||
**curr[1-4]_max_alarm**
|
||||
|
||||
The driver provides for voltage: input, critical and low critical thresholds
|
||||
and critical and low critical alarms.
|
||||
The driver exports the following attributes for via the sysfs files, where
|
||||
indexes 1, 2 are for "vin" and 3, 4 for "vout":
|
||||
|
||||
**in[1-4]_crit**

**in[1-4_label**
|
||||
|
||||
**in[1-4]_lcrit**
|
||||
|
||||
**in[1-41_lcrit_alarm**
|
||||
|
||||
The driver provides for power: input and alarms. Power alarm is supported only
|
||||
for power input.
|
||||
The driver exports the following attributes for via the sysfs files, where
|
||||
indexes 1, 2 are for "pin" and 3, 4 for "pout":
|
||||

* hwmon: Driver for SCSI/ATA temperature sensors
|
||||
* by Constantin Baranov <const@mimas.ru>, submitted September 2009
|
||||
*
|
||||
* This drive supports reporting the temperatire of SATA drives. It can be
|
||||
* easily extended to report the temperature of SCSI drives.
|
||||
*
|
||||
* The primary means to read drive temperatures and temperature limits
|
||||
* for ATA drives is the SCT Command Transport feature set as specified in
|
||||
* ATA8-ACS.
|
||||
* It can be used to read the current drive temperature, temperature limits,
|
||||
* and historic minimum and maximum temperatures. The SCT Command Transport
|
||||
* feature set is documented in "AT Attachment 8 - ATA/ATAPI Command Set
|
||||
* (ATA8-ACS)".
|
||||
*
|
||||
* If the SCT Command Transport feature set is not available, drive temperatures
|
||||
* may be readable through SMART attributes. Since SMART attributes are not well
|
||||
* defined, this method is only used as fallback mechanism.
|
||||
*
|
||||
* There are three SMART attributes which may report drive temperatures.
|
||||
* Those are defined as follows (from
|
||||
* http://www.cropel.com/library/smart-attribute-list.aspx).
|
||||
*
|
||||
* 190 Temperature Temperature, monitored by a sensor somewhere inside
|
||||
* the drive. Raw value typicaly holds the actual
|
||||
* temperature (hexadecimal) in its rightmost two digits.
|
||||
*
|
||||
* 194 Temperature Temperature, monitored by a sensor somewhere inside
|
||||
* the drive. Raw value typicaly holds the actual
|
||||
* temperature (hexadecimal) in its rightmost two digits.
|
||||
*
|
||||
* 231 Temperature Temperature, monitored by a sensor somewhere inside
|
||||
* the drive. Raw value typicaly holds the actual
|
||||
* temperature (hexadecimal) in its rightmost two digits.
|
||||
*
|
||||
* Wikipedia defines attributes a bit differently.
|
||||
*
|
||||
* 190 Temperature Value is equal to (100-temp. °C), allowing manufacturer
|
||||
* Difference or to set a minimum threshold which corresponds to a
|
||||
* Airflow maximum temperature. This also follows the convention of
|
||||
* Temperature 100 being a best-case value and lower values being
|
||||
* undesirable. However, some older drives may instead
|
||||
* report raw Temperature (identical to 0xC2) or
|
||||
* Temperature minus 50 here.
|
||||
* 194 Temperature or Indicates the device temperature, if the appropriate
|
||||
* Temperature sensor is fitted. Lowest byte of the raw value contains
|
||||
* Celsius the exact temperature value (Celsius degrees).
|
||||
* 231 Life Left Indicates the approximate SSD life left, in terms of
|
||||
* (SSDs) or program/erase cycles or available reserved blocks.
|
||||
* Temperature A normalized value of 100 represents a new drive, with
|
||||
* a threshold value at 10 indicating a need for
|
||||
* replacement. A value of 0 may mean that the drive is
|
||||
* operating in read-only mode to allow data recovery.
|
||||
* Previously (pre-2010) occasionally used for Drive
|
||||
* Temperature (more typically reported at 0xC2).
|
||||
*
|
||||
* Common denominator is that the first raw byte reports the temperature
|
||||
* in degrees C on almost all drives. Some drives may report a fractional
|
||||
* temperature in the second raw byte.
|
||||
*
|
||||
* Known exceptions (from libatasmart):
|
||||
* - SAMSUNG SV0412H and SAMSUNG SV1204H) report the temperature in 10th
|
||||
* degrees C in the first two raw bytes.
|
||||
* - A few Maxtor drives report an unknown or bad value in attribute 194.
|
||||
* - Certain Apple SSD drives report an unknown value in attribute 190.
|
||||
* Only certain firmware versions are affected.
|
||||
*
|
||||
* Those exceptions affect older ATA drives and are currently ignored.
|
||||
* Also, the second raw byte (possibly reporting the fractional temperature)
|
||||
* is currently ignored.
|
||||
*
|
||||
* Many drives also report temperature limits in additional SMART data raw
|
||||
* bytes. The format of those is not well defined and varies widely.
|
||||
* The driver does not currently attempt to report those limits.
|
||||
*
|
||||
* According to data in smartmontools, attribute 231 is rarely used to report
|
||||
* drive temperatures. At the same time, several drives report SSD life left
|
||||
* in attribute 231, but do not support temperature sensors. For this reason,
|
||||
* attribute 231 is currently ignored.
|
||||
*
|
||||
* Following above definitions, temperatures are reported as follows.
|
||||
* If SCT Command Transport is supported, it is used to read the
|
||||
* temperature and, if available, temperature limits.
|
||||
* - Otherwise, if SMART attribute 194 is supported, it is used to read
|
||||
* the temperature.
|
||||
* - Otherwise, if SMART attribute 190 is supported, it is used to read
|
||||
* the temperature.
