+Description
+-----------
+
+The Energy driver exposes the energy counters that are
+reported via the Running Average Power Limit (RAPL)
+Model-specific Registers (MSRs) via the hardware monitor
+(HWMON) sysfs interface.
+
+1. Power, Energy and Time Units
+ MSR_RAPL_POWER_UNIT/ C001_0299:
+ shared with all cores in the socket
+
+2. Energy consumed by each Core
+ MSR_CORE_ENERGY_STATUS/ C001_029A:
+ 32-bitRO, Accumulator, core-level power reporting
+
+3. Energy consumed by Socket
+ MSR_PACKAGE_ENERGY_STATUS/ C001_029B:
+ 32-bitRO, Accumulator, socket-level power reporting,
+ shared with all cores in socket
+
+These registers are updated every 1ms and cleared on
+reset of the system.
+
+Note: If SMT is enabled, Linux enumerates all threads as cpus.
+Since, the energy status registers are accessed at core level,
+reading those registers from the sibling threads would result
+in duplicate values. Hence, energy counter entries are not
+populated for the siblings.
+
+Energy Caluclation
+------------------
+
+Energy information (in Joules) is based on the multiplier,
+1/2^ESU; where ESU is an unsigned integer read from
+MSR_RAPL_POWER_UNIT register. Default value is 10000b,
+indicating energy status unit is 15.3 micro-Joules increment.
+
+Reported values are scaled as per the formula
+
+scaled value = ((1/2^ESU) * (Raw value) * 1000000UL) in uJoules
+
+Users calculate power for a given domain by calculating
+ dEnergy/dTime for that domain.
+
+Energy accumulation
+--------------------------
+
+Current, Socket energy status register is 32bit, assuming a 240W
+2P system, the register would wrap around in
+
+ 2^32*15.3 e-6/240 * 2 = 547.60833024 secs to wrap(~9 mins)
+
+The Core energy register may wrap around after several days.
+
+To improve the wrap around time, a kernel thread is implemented
+to accumulate the socket energy counters and one core energy counter
+per run to a respective 64-bit counter. The kernel thread starts
+running during probe, wakes up every 100secs and stops running
+when driver is removed.
+
+Frequency of the accumulator thread is set during the probe
+based on the chosen energy unit resolution. For example
+A. fine grain (1.625 micro J)
+B. course grain (0.125 milli J)
+
+A socket and core energy read would return the current register
+value added to the respective energy accumulator.

+
+Description
+-----------
+
+This driver implements support for the hardware monitoring capabilities of the
+embedded into Baikal-T1 process, voltage and temperature sensors. PVT IP-core
+consists of one temperature and four voltage sensors, which can be used to
+monitor the chip internal environment like heating, supply voltage and
+transistors performance. The driver can optionally provide the hwmon alarms
+for each sensor the PVT controller supports. The alarms functionality is made
+compile-time configurable due to the hardware interface implementation
+peculiarity, which is connected with an ability to convert data from only one
+sensor at a time. Additional limitation is that the controller performs the
+thresholds checking synchronously with the data conversion procedure. Due to
+these in order to have the hwmon alarms automatically detected the driver code
+must switch from one sensor to another, read converted data and manually check
+the threshold status bits. Depending on the measurements timeout settings
+(update_interval sysfs node value) this design may cause additional burden on
+the system performance. So in case if alarms are unnecessary in your system
+design it's recommended to have them disabled to prevent the PVT IRQs being
+periodically raised to get the data cache/alarms status up to date. By default
+in alarm-less configuration the data conversion is performed by the driver
+on demand when read operation is requested via corresponding _input-file.
+
+Temperature Monitoring
+----------------------
+
+Temperature is measured with 10-bit resolution and reported in millidegree
+Celsius. The driver performs all the scaling by itself therefore reports true
+temperatures that don't need any user-space adjustments. While the data
+translation formulae isn't linear, which gives us non-linear discreteness,
+it's close to one, but giving a bit better accuracy for higher temperatures.
+The temperature input is mapped as follows (the last column indicates the input
+ranges)::
+
+ temp1: CPU embedded diode -48.38C - +147.438C
+
+In case if the alarms kernel config is enabled in the driver the temperature input
+has associated min and max limits which trigger an alarm when crossed.
+
+Voltage Monitoring
+------------------
+
+The voltage inputs are also sampled with 10-bit resolution and reported in
+millivolts. But in this case the data translation formulae is linear, which
+provides a constant measurements discreteness. The data scaling is also
+performed by the driver, so returning true millivolts. The voltage inputs are
+mapped as follows (the last column indicates the input ranges)::
+
+ in0: VDD (processor core) 0.62V - 1.168V
+ in1: Low-Vt (low voltage threshold) 0.62V - 1.168V
+ in2: High-Vt (high voltage threshold) 0.62V - 1.168V
+ in3: Standard-Vt (standard voltage threshold) 0.62V - 1.168V
+
+In case if the alarms config is enabled in the driver the voltage inputs
+have associated min and max limits which trigger an alarm when crossed.

+Description
+-----------
+
+On many Dell laptops the System Management Mode (SMM) BIOS can be
+queried for the status of fans and temperature sensors. Userspace
+utilities like ``sensors`` can be used to return the readings. The
+userspace suite `i8kutils`__ can also be used to read the sensors and
+automatically adjust fan speed (please notice that it currently uses
+the deprecated ``/proc/i8k`` interface).
+
+ __ https://github.com/vitorafsr/i8kutils
+
+``sysfs`` interface
+-------------------
+
+Temperature sensors and fans can be queried and set via the standard
+``hwmon`` interface on ``sysfs``, under the directory
+``/sys/class/hwmon/hwmonX`` for some value of ``X`` (search for the
+``X`` such that ``/sys/class/hwmon/hwmonX/name`` has content
+``dell_smm``). A number of other attributes can be read or written:
+
+=============================== ======= =======================================
+Name Perm Description
+=============================== ======= =======================================
+fan[1-3]_input RO Fan speed in RPM.
+fan[1-3]_label RO Fan label.
+pwm[1-3] RW Control the fan PWM duty-cycle.
+pwm1_enable WO Enable or disable automatic BIOS fan
+ control (not supported on all laptops,
+ see below for details).
+temp[1-10]_input RO Temperature reading in milli-degrees
+ Celsius.
+temp[1-10]_label RO Temperature sensor label.
+=============================== ======= =======================================
+
+Disabling automatic BIOS fan control
+------------------------------------
+
+On some laptops the BIOS automatically sets fan speed every few
+seconds. Therefore the fan speed set by mean of this driver is quickly
+overwritten.
+
+There is experimental support for disabling automatic BIOS fan
+control, at least on laptops where the corresponding SMM command is
+known, by writing the value ``1`` in the attribute ``pwm1_enable``
+(writing ``2`` enables automatic BIOS control again). Even if you have
+more than one fan, all of them are set to either enabled or disabled
+automatic fan control at the same time and, notwithstanding the name,
+``pwm1_enable`` sets automatic control for all fans.
+
+If ``pwm1_enable`` is not available, then it means that SMM codes for
+enabling and disabling automatic BIOS fan control are not whitelisted
+for your hardware. It is possible that codes that work for other
+laptops actually work for yours as well, or that you have to discover
+new codes.
+
+Check the list ``i8k_whitelist_fan_control`` in file
+``drivers/hwmon/dell-smm-hwmon.c`` in the kernel tree: as a first
+attempt you can try to add your machine and use an already-known code
+pair. If, after recompiling the kernel, you see that ``pwm1_enable``
+is present and works (i.e., you can manually control the fan speed),
+then please submit your finding as a kernel patch, so that other users
+can benefit from it. Please see
+:ref:`Documentation/process/submitting-patches.rst <submittingpatches>`
+for information on submitting patches.
+
+If no known code works on your machine, you need to resort to do some
+probing, because unfortunately Dell does not publish datasheets for
+its SMM. You can experiment with the code in `this repository`__ to
+probe the BIOS on your machine and discover the appropriate codes.
+
+ __ https://github.com/clopez/dellfan/
+
+Again, when you find new codes, we'd be happy to have your patches!
+
+Module parameters
+-----------------
+
+* force:bool
+ Force loading without checking for supported
+ models. (default: 0)
+
+* ignore_dmi:bool
+ Continue probing hardware even if DMI data does not
+ match. (default: 0)
+
+* restricted:bool
+ Allow fan control only to processes with the
+ ``CAP_SYS_ADMIN`` capability set or processes run
+ as root when using the legacy ``/proc/i8k``
+ interface. In this case normal users will be able
+ to read temperature and fan status but not to
+ control the fan. If your notebook is shared with
+ other users and you don't trust them you may want
+ to use this option. (default: 1, only available
+ with ``CONFIG_I8K``)
+
+* power_status:bool
+ Report AC status in ``/proc/i8k``. (default: 0,
+ only available with ``CONFIG_I8K``)
+
+* fan_mult:uint
+ Factor to multiply fan speed with. (default:
+ autodetect)
+
+* fan_max:uint
+ Maximum configurable fan speed. (default:
+ autodetect)
+
+Legacy ``/proc`` interface
+--------------------------
+
+.. warning:: This interface is obsolete and deprecated and should not
+ used in new applications. This interface is only
+ available when kernel is compiled with option
+ ``CONFIG_I8K``.
+
+The information provided by the kernel driver can be accessed by
+simply reading the ``/proc/i8k`` file. For example::
+
+ $ cat /proc/i8k
+ 1.0 A17 2J59L02 52 2 1 8040 6420 1 2
+
+The fields read from ``/proc/i8k`` are::
+
+ 1.0 A17 2J59L02 52 2 1 8040 6420 1 2
+ | | | | | | | | | |
+ | | | | | | | | | +------- 10. buttons status
+ | | | | | | | | +--------- 9. AC status
+ | | | | | | | +-------------- 8. fan0 RPM
+ | | | | | | +------------------- 7. fan1 RPM
+ | | | | | +--------------------- 6. fan0 status
+ | | | | +----------------------- 5. fan1 status
+ | | | +-------------------------- 4. temp0 reading (Celsius)
+ | | +---------------------------------- 3. Dell service tag (later known as 'serial number')
+ | +-------------------------------------- 2. BIOS version
+ +------------------------------------------ 1. /proc/i8k format version
+
+A negative value, for example -22, indicates that the BIOS doesn't
+return the corresponding information. This is normal on some
+models/BIOSes.
+
+For performance reasons the ``/proc/i8k`` doesn't report by default
+the AC status since this SMM call takes a long time to execute and is
+not really needed. If you want to see the ac status in ``/proc/i8k``
+you must explictitly enable this option by passing the
+``power_status=1`` parameter to insmod. If AC status is not
+available -1 is printed instead.
+
+The driver provides also an ioctl interface which can be used to
+obtain the same information and to control the fan status. The ioctl
+interface can be accessed from C programs or from shell using the
+i8kctl utility. See the source file of ``i8kutils`` for more
+information on how to use the ioctl interface.

+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.
+
+
+Usage Note
+----------
+
+Reading the drive temperature may reset the spin down timer on some drives.
+This has been observed with WD120EFAX drives, but may be seen with other
+drives as well. The same behavior is observed if the 'hdtemp' or 'smartd'
+tools are used to access the drive.
+With the WD120EFAX drive, reading the drive temperature using the drivetemp
+driver is still possible _after_ it transitioned to standby mode, and
+reading the drive temperature in this mode will not cause the drive to
+change its mode (meaning the drive will not spin up). It is unknown if other
+drives experience similar behavior.
+
+A known workaround for WD120EFAX drives is to read the drive temperature at
+intervals larger than twice the spin-down time. Otherwise affected drives
+will never spin down.
+
+
+Sysfs entries

+available only if reported by the drive. All temperatures are reported in

+Description:
+------------
+
+This driver supports hardware monitoring for the temperature sensor,
+various ADC's connected to the GSC, and optional FAN controller available
+on some boards.
+
+
+Voltage Monitoring
+------------------
+
+The voltage inputs are scaled either internally or by the driver depending
+on the GSC version and firmware. The values returned by the driver do not need
+further scaling. The voltage input labels provide the voltage rail name:
+
+inX_input Measured voltage (mV).
+inX_label Name of voltage rail.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are measured with 12-bit or 10-bit resolution and are scaled
+either internally or by the driver depending on the GSC version and firmware.
+The values returned by the driver reflect millidegree Celcius:
+
+tempX_input Measured temperature.
+tempX_label Name of temperature input.
+
+
+PWM Output Control
+------------------
+
+The GSC features 1 PWM output that operates in automatic mode where the
+PWM value will be scalled depending on 6 temperature boundaries.
+The tempeature boundaries are read-write and in millidegree Celcius and the
+read-only PWM values range from 0 (off) to 255 (full speed).
+Fan speed will be set to minimum (off) when the temperature sensor reads
+less than pwm1_auto_point1_temp and maximum when the temperature sensor
+equals or exceeds pwm1_auto_point6_temp.

+Description
+-----------
+
+This driver adds the temperature, voltage, current and power reading
+support for the Intel MAX 10 Board Management Controller (BMC) chip.
+The BMC chip is integrated in some Intel Programmable Acceleration
+Cards (PAC). It connects to a set of sensor chips to monitor the
+sensor data of different components on the board. The BMC firmware is
+responsible for sensor data sampling and recording in shared
+registers. The host driver reads the sensor data from these shared
+registers and exposes them to users as hwmon interfaces.
+
+The BMC chip is implemented using the Intel MAX 10 CPLD. It could be
+reprogramed to some variants in order to support different Intel
+PACs. The driver is designed to be able to distinguish between the
+variants, but now it only supports the BMC for Intel PAC N3000.

Description
-----------
-Intersil ISL68137 is a digital output 7-phase configurable PWM
-controller with an AVSBus interface.
+This driver supports the Renesas ISL68137 and all 2nd generation Renesas
+digital multiphase voltage regulators (raa_dmpvr2). The ISL68137 is a digital
+output 7-phase configurable PWM controller with an AVSBus interface. 2nd
+generation devices are grouped into 4 distinct configurations: '1rail' for
+single-rail devices, '2rail' for dual-rail devices, '3rail' for 3-rail devices,
+and 'hv' for high voltage single-rail devices. Consult the individual datasheets

+Description
+___________
+
+The LTC2947 is a high precision power and energy monitor that measures current,
+voltage, power, temperature, charge and energy. The device supports both SPI
+and I2C depending on the chip configuration.
+The device also measures accumulated quantities as energy. It has two banks of
+register's to read/set energy related values. These banks can be configured
+independently to have setups like: energy1 accumulates always and enrgy2 only
+accumulates if current is positive (to check battery charging efficiency for
+example). The device also supports a GPIO pin that can be configured as output
+to control a fan as a function of measured temperature. Then, the GPIO becomes
+active as soon as a temperature reading is higher than a defined threshold. The
+temp2 channel is used to control this thresholds and to read the respective
+alarms.
+
+Sysfs entries

+

+is write-only and all the other attributes are read-only.

+The MAX31730 temperature sensor monitors its own temperature and the

+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.

+hardware monitoring might be supported.
+
+The fan supervisor has a 7 bit counter register and a counter period of 1
+second. If the 7 bit counter overflows, the supervisor will automatically
+switch to x8 mode to support a wider input range at the loss of
+granularity.

+
+Description
+-----------
+
+This driver implements support for Texas Instruments TMP512, and TMP513.
+The TMP512 (dual-channel) and TMP513 (triple-channel) are system monitors
+that include remote sensors, a local temperature sensor, and a high-side current
+shunt monitor. These system monitors have the capability of measuring remote
+temperatures, on-chip temperatures, and system voltage/power/current
+consumption.
+
+The temperatures are measured in degrees Celsius with a range of
+-40 to + 125 degrees with a resolution of 0.0625 degree C.
+
+For hysteresis value, only the first channel is writable. Writing to it
+will affect all other values since each channels are sharing the same
+hysteresis value. The hysteresis is in degrees Celsius with a range of
+0 to 127.5 degrees with a resolution of 0.5 degree.
+
+The driver exports the temperature values via the following sysfs files:
+
+**temp[1-4]_input**
+
+**temp[1-4]_crit**
+
+**temp[1-4]_crit_alarm**
+
+**temp[1-4]_crit_hyst**
+
+The driver read the shunt voltage from the chip and convert it to current.
+The readable range depends on the "ti,pga-gain" property (default to 8) and the
+shunt resistor value. The value resolution will be equal to 10uV/Rshunt.
+
+The driver exports the shunt currents values via the following sysFs files:
+
+**curr1_input**
+
+**curr1_lcrit**
+
+**curr1_lcrit_alarm**
+
+**curr1_crit**
+
+**curr1_crit_alarm**
+
+The bus voltage range is read from the chip with a resolution of 4mV. The chip
+can be configurable in two different range (32V or 16V) using the
+ti,bus-range-microvolt property in the devicetree.
+
+The driver exports the bus voltage values via the following sysFs files:
+
+**in0_input**
+
+**in0_lcrit**
+
+**in0_lcrit_alarm**
+
+**in0_crit**
+
+**in0_crit_alarm**
+
+The bus power and bus currents range and resolution depends on the calibration
+register value. Those values are calculate by the hardware using those
+formulas:
+
+Current = (ShuntVoltage * CalibrationRegister) / 4096
+Power = (Current * BusVoltage) / 5000
+
+The driver exports the bus current and bus power values via the following
+sysFs files:
+
+**curr2_input**
+
+**power1_input**
+
+**power1_crit**
+
+**power1_crit_alarm**
+
+The calibration process follow the procedure of the datasheet (without overflow)
+and depend on the shunt resistor value and the pga_gain value.

+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[3-4]_crit_alarm**
+
+**curr[1-4]_input**
+
+**curr[1-4]_label**
+
+**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.
