Throttling here refers to the GT frequency being clipped. Each of the throttle reason attributes will have a 0 or 1 value depending upon whether there is throttling and also the specific reason for it. The following is a brief description of the sysfs throttle frequency attributes added: - throttle_reason_status: when set indicates that there is GT frequency clipping. - throttle_reason_pl1: when set indicates that PBM PL1 (platform or package PL1) has caused GT frequency clipping. - throttle_reason_pl2: when set indicates that PBM PL2 or PL3 (platform or package PL2 or PL3) has caused GT frequency clipping. - throttle_reason_pl4: when set indicates that PL4 or IccMax has caused GT frequency clipping. - throttle_reason_thermal: when set indicates that Thermal event has caused GT frequency clipping. - throttle_reason_prochot: when set indicates that PROCHOT# has caused GT frequency clipping. - throttle_reason_ratl: when set indicates that Running Average Thermal Limit has caused GT frequency clipping. - throttle_reason_vr_thermalert: when set indicates that Hot VR (any processor VR) has caused GT frequency clipping. - throttle_reason_vr_tdc: when set indicates that VR TDC (Thermal Design Current) has caused GT frequency clipping.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
