From: Zhang Rui <rui.zhang@intel.com> mainline inclusion from mainline-v5.3-rc1 commit 32fb480e0a2cf1f71e4174d6477198c94dbc746c category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I47H3V CVE: NA -------------------------------- commit 32fb480e0a2cf1f71e4174d6477198c94dbc746c upstream. RAPL "package" domains are actually implemented in hardware per-die. Thus, the new multi-die/package systems have mulitple domains within each physical package. Update the intel_rapl driver to be "die aware" -- exporting multiple domains within a single package, when present. No change on single die/package systems.
