^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 87) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 88) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 89)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 90) This driver permits reading of the internal temperature sensor of AMD
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 91) Family 10h/11h/12h/14h/15h/16h processors.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 92)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 93) All these processors have a sensor, but on those for Socket F or AM2+,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 94) the sensor may return inconsistent values (erratum 319). The driver
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 95) will refuse to load on these revisions unless you specify the "force=1"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 96) module parameter.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 97)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 98) Due to technical reasons, the driver can detect only the mainboard's
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 99) socket type, not the processor's actual capabilities. Therefore, if you
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 100) are using an AM3 processor on an AM2+ mainboard, you can safely use the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 101) "force=1" parameter.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 102)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 103) For CPUs older than Family 17h, there is one temperature measurement value,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 104) available as temp1_input in sysfs. It is measured in degrees Celsius with a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 105) resolution of 1/8th degree. Please note that it is defined as a relative
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 106) value; to quote the AMD manual::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 107)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 108) Tctl is the processor temperature control value, used by the platform to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 109) control cooling systems. Tctl is a non-physical temperature on an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 110) arbitrary scale measured in degrees. It does _not_ represent an actual
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 111) physical temperature like die or case temperature. Instead, it specifies
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 112) the processor temperature relative to the point at which the system must
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 113) supply the maximum cooling for the processor's specified maximum case
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 114) temperature and maximum thermal power dissipation.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 115)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 116) The maximum value for Tctl is available in the file temp1_max.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 117)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 118) If the BIOS has enabled hardware temperature control, the threshold at
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 119) which the processor will throttle itself to avoid damage is available in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 120) temp1_crit and temp1_crit_hyst.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 121)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 122) On some AMD CPUs, there is a difference between the die temperature (Tdie) and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 123) the reported temperature (Tctl). Tdie is the real measured temperature, and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 124) Tctl is used for fan control. While Tctl is always available as temp1_input,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 125) the driver exports Tdie temperature as temp2_input for those CPUs which support
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 126) it.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 127)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 128) Models from 17h family report relative temperature, the driver aims to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 129) compensate and report the real temperature.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 130)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 131) On Family 17h and Family 18h CPUs, additional temperature sensors may report
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 132) Core Complex Die (CCD) temperatures. Up to 8 such temperatures are reported
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 133) as temp{3..10}_input, labeled Tccd{1..8}. Actual support depends on the CPU
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 134) variant.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 135)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 136) Various Family 17h and 18h CPUs report voltage and current telemetry
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 137) information. The following attributes may be reported.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 148) reported as multiples of 1A / LSB. SoC is reported as multiples of 0.25A
