CSV output is tricky to format and column layout changes are susceptible
to breaking parsers. New JSON-formatted output has variable names to
identify fields that are consistent and informative, making the output
parseable.
CSV output example:
1.20,msec,task-clock:u,1204272,100.00,0.697,CPUs utilized
0,,context-switches:u,1204272,100.00,0.000,/sec
0,,cpu-migrations:u,1204272,100.00,0.000,/sec
70,,page-faults:u,1204272,100.00,58.126,K/sec
JSON output example:
{"counter-value" : "3805.723968", "unit" : "msec", "event" :
"cpu-clock", "event-runtime" : 3805731510100.00, "pcnt-running"

: 100.00, "metric-value" : 54.654516, "metric-unit" : "/sec"}
Also added documentation for JSON option.
There is some tidy up of CSV code including a potential memory over run
in the os.nfields set up. To facilitate this an AGGR_MAX value is added.
Committer notes:
Fixed up using PRIu64 to format u64 values, not %lu.

Topdown metrics are missed in the default perf stat on the hybrid machine,
add Topdown metrics in default perf stat for hybrid systems.
Currently, we support the perf metrics Topdown for the p-core PMU in the
perf stat default, the perf metrics Topdown support for e-core PMU will be
implemented later separately. Refactor the code adds two x86 specific
functions. Widen the size of the event name column by 7 chars, so that all
metrics after the "#" become aligned again.
The perf metrics topdown feature is supported on the cpu_core of ADL. The
dedicated perf metrics counter and the fixed counter 3 are used for the
topdown events. Adding the topdown metrics doesn't trigger multiplexing.

This reverts commit 60344f1a9a597f2e0efcd57df5dad0b42da15e21. Hybrid metrics place a PMU at the end of the parse string. This is also where tool events are placed.

per pmu.

Sometimes, it's also useful to aggregate event counts from all PMUs.
Create a new option '--hybrid-merge' to enable that behavior and report
the counts without PMUs.

One metric such as 'Kernel_Utilization' may be from different PMUs and
consists of different events.
For core,
Kernel_Utilization = cpu_clk_unhalted.thread:k / cpu_clk_unhalted.thread
For atom,
Kernel_Utilization = cpu_clk_unhalted.core:k / cpu_clk_unhalted.core
The metric group string for core is:
'{cpu_clk_unhalted.thread/metric-id=cpu_clk_unhalted.thread:k/k,cpu_clk_unhalted.thread/metric-id=cpu_clk_unhalted.thread/}:W'
It's internally expanded to:
'{cpu_clk_unhalted.thread_p/metric-id=cpu_clk_unhalted.thread_p:k/k,cpu_clk_unhalted.thread/metric-id=cpu_clk_unhalted.thread/}:W#cpu_core'
The metric group string for atom is:
'{cpu_clk_unhalted.core/metric-id=cpu_clk_unhalted.core:k/k,cpu_clk_unhalted.core/metric-id=cpu_clk_unhalted.core/}:W'
It's internally expanded to:
'{cpu_clk_unhalted.core/metric-id=cpu_clk_unhalted.core:k/k,cpu_clk_unhalted.core/metric-id=cpu_clk_unhalted.core/}:W#cpu_atom'
That means the group "{cpu_clk_unhalted.thread:k,cpu_clk_unhalted.thread}:W"
is from cpu_core PMU and the group "{cpu_clk_unhalted.core:k,cpu_clk_unhalted.core}"
is from cpu_atom PMU. And then next, check if the events in the group are
valid on that PMU. If one event is not valid on that PMU, the associated
group would be removed internally.
In this example, cpu_clk_unhalted.thread is valid on cpu_core and
cpu_clk_unhalted.core is valid on cpu_atom. So the checks for these two
groups are passed.

evlist contains cpus and all_cpus. all_cpus is the union of the cpu maps of all evsels. For non-task targets, cpus is set to be cpus requested from the command line, defaulting to all online cpus if no cpus are specified. For an uncore event, all_cpus may be just CPU 0 or every online CPU. This causes all_cpus to have fewer values than the cpus variable which is confusing given the 'all' in the name. To try to make the behavior clearer, rename cpus to user_requested_cpus and add comments on the two struct variables.

An event may have a number of uncore aliases that when added to the
evlist are consecutive.
If there are multiple uncore events in a group then
parse_events__set_leader_for_uncore_aliase will reorder the evlist so
that events on the same PMU are adjacent.
The collect_all_aliases function assumes that aliases are in blocks so
that only the first counter is printed and all others are marked merged.
The reordering for groups breaks the assumption and so all counts are
printed.
This change removes the assumption from collect_all_aliases
that the events are in blocks and instead processes the entire evlist.

A common problem is confusing CPU map indices with the CPU, by wrapping the CPU with a struct then this is avoided. This approach is similar to atomic_t. Committer notes: To make it build with BUILD_BPF_SKEL=1 these files needed the conversions to 'struct perf_cpu' usage: tools/perf/util/bpf_counter.c tools/perf/util/bpf_counter_cgroup.c tools/perf/util/bpf_ftrace.c Also perf_env__get_cpu() was removed back in "perf cpumap: Switch cpu_map__build_map to cpu function". Additionally these needed to be fixed for the ARM builds to complete: tools/perf/arch/arm/util/cs-etm.c tools/perf/arch/arm64/util/pmu.c Suggested-by: John Garry <john.garry@huawei.com> Signed-off-by: Ian Rogers <irogers@google.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: James Clark <james.clark@arm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Kajol Jain <kjain@linux.ibm.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Leo Yan <leo.yan@linaro.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Mike Leach <mike.leach@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Clarke <pc@us.ibm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Riccardo Mancini <rickyman7@gmail.com> Cc: Stephane Eranian <eranian@google.com> Cc: Suzuki Poulouse <suzuki.poulose@arm.com> Cc: Vineet Singh <vineet.singh@intel.com> Cc: coresight@lists.linaro.org Cc: linux-arm-kernel@lists.infradead.org Cc: zhengjun.xing@intel.com Link: https://lore.kernel.org/r/20220105061351.120843-49-irogers@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
