perf list picks the events supported for specific platform
from pmu-events/arch/powerpc/<platform>. Example power10 events
are in pmu-events/arch/powerpc/power10, power9 events are part
of pmu-events/arch/powerpc/power9. The decision of which
platform to pick is determined based on PVR value in powerpc.
The PVR value is matched from pmu-events/arch/powerpc/mapfile.csv
Example:
Format:
PVR,Version,JSON/file/pathname,Type
0x004[bcd][[:xdigit:]]{4},1,power8,core
0x0066[[:xdigit:]]{4},1,power8,core
0x004e[[:xdigit:]]{4},1,power9,core
0x0080[[:xdigit:]]{4},1,power10,core
0x0082[[:xdigit:]]{4},1,power10,core
The code gets the PVR from system using get_cpuid_str function
in arch/powerpc/util/headers.c ( from SPRN_PVR ) and compares
with value from mapfile.csv
In case of compat mode, say when partition is booted in a power9
mode when the system is a power10, add an entry to pick the
ISA architected events from "pmu-events/arch/powerpc/compat".
Add json file generic-events.json which will contain these
events which is supported in compat mode.
