# HEAD: eb876fbc248e6eb4773a5bc80d205ff7262b1bb5 perf/x86/intel/rapl: Cosmetic rename internal variables in response to multi-die/pkg support
Implement multi-die topology support on Intel CPUs and expose the die topology to user-space tooling, by Len Brown, Kan Liang and Zhang Rui.
These changes should have no effect on the kernel's existing understanding of topologies, i.e. there should be no behavioral impact on cache, NUMA, scheduler, perf and other topologies and overall system performance.
