Briefly, the files above are:
- core_id: the CPU core ID of cpuX. Typically it is the
- hardware platform's identifier (rather than the kernel's).
- The actual value is architecture and platform dependent.
-
core_siblings: internal kernel map of cpuX's hardware threads
within the same physical_package_id.
