Currently the `perf test` always fails the coresight test like:
89: Check Arm CoreSight trace data recording and synthesized samples: FAILED!
That is because the test_arm_coresight.sh is attempting to SIGINT the
parent but is using $$ rather than $PPID and it sigint's itself when
run under the perf test framework.
Since this is done in a trap clause it ends up returning a non zero
return.
Since $PPID is a bash ism and not all distros are linking /bin/sh to
bash, the alternative parent pid lookups are uglier than just dropping
the kill, and its not strictly needed, lets pick the simple solution and
drop the sigint.

BUG_ON is a no-op if NDEBUG is defined, otherwise it is an assert.
Compiling with NDEBUG yields:
bench/numa.c: In function ‘bind_to_cpu’:
bench/numa.c:314:1: error: control reaches end of non-void function [-Werror=return-type]
314 | }
| ^
bench/numa.c: In function ‘bind_to_node’:
bench/numa.c:367:1: error: control reaches end of non-void function [-Werror=return-type]
367 | }
| ^
Add return statements to cover this case.

Switch some raw accesses to the cpu map to using the library API. This
can help with reference count checking. Some BPF cases switch from index
to CPU for consistency, this shouldn't matter as the CPU map is full.

This fixes the issue where the build will fail if only the Python2
runtime is installed but the Python3 devtools are installed. Currently
the workaround is 'make PYTHON=python3'.
Fix it by autodetecting Python based on whether python[x]-config exists
rather than just python[x] because both are needed for the build. Then
-config is stripped to find the Python runtime.
Testing
=======
* Auto detect links with Python3 when the v3 devtools are installed
and only Python 2 runtime is installed
* Auto detect links with Python2 when both devtools are installed
* Sensible warning is printed if no Python devtools are installed
* 'make PYTHON=x' still automatically sets PYTHON_CONFIG=x-config
* 'make PYTHON=x' fails if x-config doesn't exist
* 'make PYTHON=python3' overrides Python2 devtools
* 'make PYTHON=python2' overrides Python3 devtools
* 'make PYTHON_CONFIG=x-config' works
* 'make PYTHON=x PYTHON_CONFIG=x' works
* 'make PYTHON=missing' reports an error
* 'make PYTHON_CONFIG=missing' reports an error

Now arch-specific functions all do the same thing. When it fixes the
symbol address it needs to check the boundary between the kernel image
and modules. For the last symbol in the previous region, it cannot
know the exact size as it's discarded already. Thus it just uses a
small page size (4096) and rounds it up like the last symbol.

The symbol fixup is necessary for symbols in kallsyms since they don't
have size info. So we use the next symbol's address to calculate the
size. Now it's also used for user binaries because sometimes they miss
size for hand-written asm functions.
There's a arch-specific function to handle kallsyms differently but
currently it cannot distinguish kallsyms from others. Pass this
information explicitly to handle it properly. Note that those arch
functions will be moved to the generic function so I didn't added it to
the arch-functions.

Since for cpu_core or cpu_atom, they have different topdown events
groups.
For cpu_core, --topdown equals to:
"{slots,cpu_core/topdown-retiring/,cpu_core/topdown-bad-spec/,
cpu_core/topdown-fe-bound/,cpu_core/topdown-be-bound/,
cpu_core/topdown-heavy-ops/,cpu_core/topdown-br-mispredict/,
cpu_core/topdown-fetch-lat/,cpu_core/topdown-mem-bound/}"
For cpu_atom, --topdown equals to:
"{cpu_atom/topdown-retiring/,cpu_atom/topdown-bad-spec/,
cpu_atom/topdown-fe-bound/,cpu_atom/topdown-be-bound/}"
To simplify the implementation, on hybrid, --topdown is used
together with --cputype. If without --cputype, it uses cpu_core
topdown events by default.
# ./perf stat --topdown -a sleep 1

Test case 71 'Convert perf time to TSC' is not supported on s390.
Subtest 71.1 is skipped with the correct message, but subtest 71.2 is
not skipped and fails.
The root cause is function evlist__open() called from
test__perf_time_to_tsc(). evlist__open() returns -ENOENT because the
event cycles:u is not supported by the selected PMU, for example
platform s390 on z/VM or an x86_64 virtual machine.
The PMU driver returns -ENOENT in this case. This error is leads to the
failure.
Fix this by returning TEST_SKIP on -ENOENT.
Output before:
71: Convert perf time to TSC:
71.1: TSC support: Skip (This architecture does not support)
71.2: Perf time to TSC: FAILED!
Output after:
71: Convert perf time to TSC:
71.1: TSC support: Skip (This architecture does not support)
71.2: Perf time to TSC: Skip (perf_read_tsc_conversion is not supported)
This also happens on an x86_64 virtual machine:
# uname -m

Since commit bb30acae4c4dacfa ("perf report: Bail out --mem-mode if mem
info is not available") "perf mem report" and "perf report --mem-mode"
don't report result if the PERF_SAMPLE_DATA_SRC bit is missed in sample
type.
The commit ffab487052054162 ("perf: arm-spe: Fix perf report
--mem-mode") partially fixes the issue. It adds PERF_SAMPLE_DATA_SRC
bit for Arm SPE event, this allows the perf data file generated by
kernel v5.18-rc1 or later version can be reported properly.
On the other hand, perf tool still fails to be backward compatibility
for a data file recorded by an older version's perf which contains Arm
SPE trace data. This patch is a workaround in reporting phase, when
detects ARM SPE PMU event and without PERF_SAMPLE_DATA_SRC bit, it will
force to set the bit in the sample type and give a warning info.

If use command 'perf script -F,+data_src' to dump memory samples with
Arm SPE trace data, it reports error:
# perf script -F,+data_src
Samples for 'dummy:u' event do not have DATA_SRC attribute set. Cannot print 'data_src' field.
This is because the 'dummy:u' event is absent DATA_SRC bit in its sample
type, so if a file contains AUX area tracing data then always allow
field 'data_src' to be selected as an option for perf script.

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.

# ./perf stat -M Kernel_Utilization -a sleep 1

It bothered me that during benchmarking using 'perf stat' (to collect
for example CPU cache events) I could not simultaneously retrieve the
times spend in user or kernel mode in a machine readable format.
When running 'perf stat' the output for humans contains the times
reported by rusage and wait4.
$ perf stat -e cache-misses:u -- true
Performance counter stats for 'true':
4,206 cache-misses:u
0.001113619 seconds time elapsed
0.001175000 seconds user
0.000000000 seconds sys
But 'perf stat's machine-readable format does not provide this information.
$ perf stat -x, -e cache-misses:u -- true
4282,,cache-misses:u,492859,100.00,,
I found no way to retrieve this information using the available events
while using machine-readable output.
This patch adds two new tool internal events 'user_time' and
'system_time', similarly to the already present 'duration_time' event.
Both events use the already collected rusage information obtained by
wait4 and tracked in the global ru_stats.
Examples presenting cache-misses and rusage information in both human
and machine-readable form:
$ perf stat -e duration_time,user_time,system_time,cache-misses -- grep -q -r duration_time .
Performance counter stats for 'grep -q -r duration_time .':
67,422,542 ns duration_time:u
50,517,000 ns user_time:u
16,839,000 ns system_time:u
30,937 cache-misses:u
0.067422542 seconds time elapsed
0.050517000 seconds user
0.016839000 seconds sys
$ perf stat -x, -e duration_time,user_time,system_time,cache-misses -- grep -q -r duration_time .

This is preparation for exporting rusage values as tool events.
Add new global stats tracking the values obtained via rusage.
For now only ru_utime and ru_stime are part of the tracked stats.
Both are stored as nanoseconds to be consistent with 'duration_time',
although the finest resolution the struct timeval data in rusage
provides are microseconds.
