The resctrl tests can accept a CPU on which the tests are run and use default of CPU #1 if it is not provided. In the CAT test a "sibling CPU" is determined that is from the same package where another thread will be run. The current algorithm with which a "sibling CPU" is determined does not take the provided/default CPU into account and when that CPU is the first CPU in a package then the "sibling CPU" will be selected to be the same CPU since it starts by picking the first CPU from core_siblings_list. Fix the "sibling CPU" selection by taking the provided/default CPU into account and ensuring a sibling that is a different CPU is selected.

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.
