Subject: [PATCH 00/10] perf: Multi-die/package support

From: Kan Liang <kan.liang@...ux.intel.com>

Add Linux perf support for multi-die/package. The first product with
multi-die is Xeon Cascade Lake-AP (CLX-AP).
The code bases on the top of Len's multi-die/package support.
https://lkml.org/lkml/2019/2/18/1534

Patch 1-4: They are generic codes for previous platforms.
Perf supports miscellaneous modules, e.g cstate, RAPL and uncore.
Their counters have the same scope of effect (per package).
But they maintain their own scope information independently.
It's very useful to abstract several common topology related codes
for these modules to reduce the code redundancy, especially when
adding counters with new scope.

Patch 5-8: Support die scope counters on CLX-AP for uncore, RAPL
and cstate.

Patch 9-10: Support per-die aggregation for perf stat and header.

Kan Liang (10):
  perf/x86/intel: Introduce a concept "domain" as the scope of counters
  perf/x86/intel/cstate: Apply "domain" for cstate
  perf/x86/intel/uncore: Apply "domain" for uncore
  perf/x86/intel/rapl: Apply "domain" for RAPL
  perf/x86/intel/domain: Add new domain type for die
  perf/x86/intel/uncore: Support die scope counters on CLX-AP
  perf/x86/intel/rapl: Support die scope counters on CLX-AP
  perf/x86/intel/cstate: Support die scope counters on CLX-AP
  perf header: Add die information in cpu topology
  perf stat: Support per-die aggregation
