1 CORETEMP(7D) Devices CORETEMP(7D) 2 3 NAME 4 coretemp - Intel core-family temperature sensor driver 5 6 SYNOPSIS 7 /dev/sensors/temperature/cpu/* 8 9 DESCRIPTION 10 The coretemp driver provides the system with a means of reading the per- 11 core and, when available, per-package digital temperature sensors on 12 Intel CPUs. Currently, the coretemp driver supports Intel Core family 13 processors after Penryn microarchitecture and Intel Atom processors 14 starting with the Silvermont microarchitecture. 15 16 Temperature information is available to the system via the fault 17 management architecture (FMA). The file system location and programming 18 interface to the coretemp driver are considered Volatile, subject to 19 change without notice, and should not be used directly. Raw temperature 20 information can be dumped through the FMA developer utility fmtopo. 21 22 SEE ALSO 23 fmadm(1M) 24 25 Intel Corporation, Intel 64 and IA-32 Architectures Software Developer's 26 Manual, Volume 3 (3A, 3B, 3C & 3D): System Programming Guide. 27 28 illumos January 10, 2020 illumos
