All the topic JSON files for a CPU model/family should be in a separate
sub directory. Thus for the Silvermont X86 CPU:
- $ ls tools/perf/pmu-events/arch/x86/Silvermont_core
- Cache.json Memory.json Virtual-Memory.json
- Frontend.json Pipeline.json
+ $ ls tools/perf/pmu-events/arch/x86/silvermont
+ cache.json memory.json virtual-memory.json
+ frontend.json pipeline.json
The JSONs folder for a CPU model/family may be placed in the root arch
folder, or may be placed in a vendor sub-folder under the arch folder
where 'pm_1plus_ppc_cmpl' is a Power8 PMU event.
-However some errors in processing may cause the perf build to fail.

Mapfile format
===============
Header line
The header line is the first line in the file, which is
- always _IGNORED_. It can empty.
+ always _IGNORED_. It can be empty.
CPUID:
CPUID is an arch-specific char string, that can be used
files, relative to the directory containing the mapfile.csv
Type:
- indicates whether the events or "core" or "uncore" events.
+ indicates whether the events are "core" or "uncore" events.
Eg:
- $ grep Silvermont tools/perf/pmu-events/arch/x86/mapfile.csv
- GenuineIntel-6-37,V13,Silvermont_core,core
- GenuineIntel-6-4D,V13,Silvermont_core,core
- GenuineIntel-6-4C,V13,Silvermont_core,core
+ $ grep silvermont tools/perf/pmu-events/arch/x86/mapfile.csv
+ GenuineIntel-6-37,v13,silvermont,core
+ GenuineIntel-6-4D,v13,silvermont,core
+ GenuineIntel-6-4C,v13,silvermont,core
i.e the three CPU models use the JSON files (i.e PMU events) listed
- in the directory 'tools/perf/pmu-events/arch/x86/Silvermont_core'.
+ in the directory 'tools/perf/pmu-events/arch/x86/silvermont'.
