thermal: intel: menlow: Get rid of this driverAccording to my information, there are no active users of this driver inthe field.Moreover, it does some really questionable things and gets in the way ofthermal core improvements, so drop it.Signed-off-by: Rafael J.

a3c1f066 - thermal/intel: Introduce Intel TCC library

Mon, 19 Dec 2022 15:46:15 +0000

thermal/intel: Introduce Intel TCC libraryThere are several different drivers that accesses the Intel TCC(thermal control circuitry) MSRs, and each of them has its ownimplementation for the same functionalities, e.g. getting the currenttemperature, getting the tj_max, and getting/setting the tj_max offset.Introduce a library to unify the code for Intel CPU TCC MSR access.At the same time, ensure the temperature is got based on the updatedtjmax value because tjmax can be changed at runtime for cases likethe Intel SST-PP (Intel Speed Select Technology - Performance Profile)level change.Signed-off-by: Zhang Rui Signed-off-by: Rafael J.

1cb19cab - thermal: intel: hfi: Minimally initialize the Hardware Feedback Interface

Thu, 27 Jan 2022 19:34:50 +0000

thermal: intel: hfi: Minimally initialize the Hardware Feedback InterfaceThe Intel Hardware Feedback Interface provides guidance to the operatingsystem about the performance and energy efficiency capabilities of eachCPU in the system. Capabilities are numbers between 0 and 255 where ahigher number represents a higher capability. For each CPU, energyefficiency and performance are reported as separate capabilities.Hardware computes these capabilities based on the operating conditions ofthe system such as power and thermal limits. These capabilities are sharedwith the operating system in a table resident in memory. Each package inthe system has its own HFI instance. Every logical CPU in the package isrepresented in the table. More than one logical CPUs may be represented ina single table entry. When the hardware updates the table, it generates apackage-level thermal interrupt.The size and format of the HFI table depend on the supported features andcan only be determined at runtime. To minimally initialize the HFI, parseits features and allocate one instance per package of a data structure withthe necessary parameters to read and navigate a local copy (i.e., owned bythe driver) of individual HFI tables.A subsequent changeset will provide per-CPU initialization and interrupthandling.Reviewed-by: Len Brown Co-developed by: Aubrey Li Signed-off-by: Aubrey Li Signed-off-by: Ricardo Neri Signed-off-by: Rafael J.

2eb87d75 - thermal/drivers/intel: Introduce tcc cooling driver

Mon, 12 Apr 2021 12:59:01 +0000

thermal/drivers/intel: Introduce tcc cooling driverOn Intel processors, the core frequency can be reduced below OS request,when the current temperature reaches the TCC (Thermal Control Circuit)activation temperature.The default TCC activation temperature is specified byMSR_IA32_TEMPERATURE_TARGET. However, it can be adjusted by specifying anoffset in degrees C, using the TCC Offset bits in the same MSR register.This patch introduces a cooling devices driver that utilizes the TCCOffset feature. The bigger the current cooling state is, the lower theeffective TCC activation temperature is, so that the processors can bethrottled earlier before system critical overheats.Note that, on different platforms, the behavior might be different onhow fast the setting takes effect, and how much the CPU frequency isreduced.This patch has been tested on a KabyLake mobile platform from me, and alsoon a CometLake platform from Doug.Signed-off-by: Zhang Rui Tested by: Doug Smythies Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/20210412125901.12549-1-rui.zhang@intel.com List of files: /linux-6.15/drivers/thermal/intel/Makefile
