The first patch in this series introduces a new resctrl file, "thread_throttle_mode", on Intel systems that exposes to the user how per-thread values are allocated to a core. This is added in support of newer Intel systems that can be configured to allocate either maximum or minimum throttling of the per-thread CLOS values to the core.
Details about the feature can be found in the commit description and in Chapter 9 of the most recent Intel ISE available from https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf
The first patch parses user input with the appropriate sysfs API that has not previously been used in resctrl. The second patch is added as a subsequent cleanup that switches existing resctrl string parsing code to also use this appropriate API.
