![]() The existing sysfs cpu/topology/core_siblings (and core_siblings_list) attributes are documented, implemented, and used by programs to represent set of logical CPUs sharing the same package. This makes sense if the next topology level above a core is always a package. But on systems where there is a die topology level between a core and a package, the name and its definition become inconsistent. So without changing its function, add a name for this map that describes what it actually is -- package CPUs -- the set of CPUs that share the same package. This new name will be immune to changes in topology, since it describes threads at the current level, not siblings at a contained level.

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.
