5d9df8731c perf vendor events power9: Remove UTF-8 characters from JSON files 
Commit 3c22ba5243 ("perf vendor events powerpc: Update POWER9
events") added and updated power9 PMU JSON events. However some of the
JSON events which are part of other.json and pipeline.json files,
contains UTF-8 characters in their brief description.  Having UTF-8
character could breaks the perf build on some distros.

Fix this issue by removing the UTF-8 characters from other.json and
pipeline.json files.

Result without the fix:

cf26e043c2 perf vendor events power10: Add JSON metric events to present CPI stall cycles in powerpc 
Power10 Performance Monitoring Unit (PMU) provides events to understand
stall cycles of different pipeline stages.  These events along with
completed instructions provides useful metrics for application tuning.

Patch implements the JSON changes to collect counter statistics to
present the high level CPI stall breakdown metrics. New metric group is
named as "CPI_STALL_RATIO" and this new metric group presents these
stall metrics:

- DISPATCHED_CPI ( Dispatch stall cycles per insn )
- ISSUE_STALL_CPI ( Issue stall cycles per insn )
- EXECUTION_STALL_CPI ( Execution stall cycles per insn )
- COMPLETION_STALL_CPI ( Completition stall cycles per insn )

To avoid multipling of events, PM_RUN_INST_CMPL event has been modified
to use PMC5(performance monitoring counter5) instead of PMC4. This
change is needed, since completion stall event is using PMC4.

Usage example:

 ./perf stat --metric-no-group -M CPI_STALL_RATIO <workload>

 Performance counter stats for 'workload':

    63,056,817,982      PM_CMPL_STALL                    #     0.28 COMPLETION_STALL_CPI
 1,743,988,038,896      PM_ISSUE_STALL                   #     7.73 ISSUE_STALL_CPI
   225,597,495,030      PM_RUN_INST_CMPL                 #     6.18 DISPATCHED_CPI
                                                  #    37.48 EXECUTION_STALL_CPI
 1,393,916,546,654      PM_DISP_STALL_CYC
 8,455,376,836,463      PM_EXEC_STALL

"--metric-no-group" is used for forcing PM_RUN_INST_CMPL to be scheduled
in all group for more accuracy.

b92dd11725 perf vendor events power10: Fix hv-24x7 metric events 
Testcase stat_all_metrics.sh fails in powerpc:

  90: perf all metrics test : FAILED!

The testcase "stat_all_metrics.sh" verifies perf stat result for all the
metric events present in perf list.  It runs perf metric events with
various commands and expects non-empty metric result.

Incase of powerpc:hv-24x7 events, some of the event count can be 0 based
on system configuration. And if that event used as denominator in divide
equation, it can cause divide by 0 error. The current nest_metric.json
file creating divide by 0 issue for some of the metric events, which
results in failure of the "stat_all_metrics.sh" test case.

Most of the metrics events have cycles or an event which expect to have
a larger value as denominator, so adding 1 to the denominator of the
metric expression as a fix.

Result in powerpc box after this patch changes:

  90: perf all metrics test : Ok

8989f5f076 perf stat: Update POWER9 metrics to utilize other metrics 
These changes take advantage of the new capability added in merge commit
00e4db5125 "Allow using computed metrics
in calculating other metrics".

The net is a simplification of the expressions for a handful of metrics,
but no functional change.

fbc2844e84 perf vendor events: Use more flexible pattern matching for CPU identification for mapfile.csv 
The powerpc cpuid information includes chip revision information.
Changes between chip revisions are usually minor bug fixes and usually
do not affect the operation of the performance monitoring hardware.

The original mapfile.csv matching requires enumerating every possible
cpuid string.  When a new minor chip revision is produced a new entry
has to be added to the mapfile.csv and the code recompiled to allow perf
to have the implementation specific perf events for this new minor
revision.  For users of various distibutions of Linux having to wait for
a new release of the kernel's perf tool to be built with these trivial
patches is inconvenient.

Using regular expressions rather than exactly string matching of the
entire cpuid string allows developers to write mapfile.csv files that do
not require patches and recompiles for each of these minor version
changes.  If special cases need to be made for some particular versions,
they can be placed earlier in the mapfile.csv file before the more
general matches.

2a118e1bd2 perf vendor events powerpc: Remove duplicate events 
Some POWER PMU event names have multiple/alternate event codes. These
alternate event codes were listed in the POWER9 JSON files for
reference.

But the perf tool does not seem to handle duplicates cleanly. 'perf
list' shows such duplicate events only once, but 'perf stat' ends up
counting the first event code twice, multiplexing if necessary and we
end up with double the event counts.

Remove the duplicate event codes from the JSON files for now.

Drop the .json suffix for events directory in the mapfile.csv.

Now that we have separate JSON files for each topic in a CPU (eg: see
tools/perf/pmu-events/arch/powerpc/power8/*.json) the .json suffix in
the mapfile is misleading and redundant.

Changelog[v3]
	- [Namhyung Kim] Remove text from PublicDescription fields if it is
          identical to or prefix of BriefDescription.

Changelog[v2]
	- [Andi Kleen] Replace the vendor-family-model,version fields with
	  cpuid,version fields (to simplify mapfile)
	- Reuse the JSON files when possible (i.e multiple cpuids can refer
	  to the same JSON file) - so drop the 004d0100.json and use
	  power8.json in multiple entries in mapfile.
	- Add few more Power8 PVRs to mapfile
