Subject[PATCH 0/2] x86/resctrl: Enable user to view thread or core throttling mode
Date
This series enumerates Memory Bandwidth Allocation (MBA) per-thread
feature and introduces a new resctrl file "thread_throttle_mode".
The file shows either "per-thread" on newer systems that implement the MBA
per-thread feature or "max" on other systems that allocate maximum
throttling per-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

This series replaces the original MBA thread throttling patch series
found at
https://lore.kernel.org/lkml/cover.1592841671.git.reinette.chatre@intel.com/

This is a simplified version of the previous series that skips the
min/max mode and just provides the per-core vs. per-thread indicator.
