0255571a16 perf cpumap: Switch to using perf_cpu_map API
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.

630af16eee perf tools: Use Python devtools for version autodetection rather than runtime
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

4d27cf1d9d perf tools: Add missing headers needed by util/data.h
'struct perf_data' in util/data.h uses the "u64" data type, which is

If we only include util/data.h, the following compilation error occurs:

  util/data.h:38:3: error: unknown type name ‘u64’
     u64    version;
     ^~~

Solution: include "linux/types.h." to add the needed type definitions.

8799ebce84 perf symbol: Update symbols__fixup_end()
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.

838425f2de perf symbol: Pass is_kallsyms to symbols__fixup_end()
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.

d7e3c39708 perf stat: Support hybrid --topdown option
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.

5bb017d4b9 perf test: Fix error message for test case 71 on s390, where it is not supported
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
   x86_64
   $ ./perf test -F 71
    71: Convert perf time to TSC  :
    71.1: TSC support             : Ok
    71.2: Perf time to TSC        : FAILED!
   $

Committer testing:

Continues to work on x86_64:

  $ perf test 71
   71: Convert perf time to TSC    :
   71.1: TSC support               : Ok
   71.2: Perf time to TSC          : Ok

ccb17caecf perf report: Set PERF_SAMPLE_DATA_SRC bit for Arm SPE event
Since commit bb30acae4c ("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 ffab487052 ("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.

60344f1a9a perf stat: Support metrics with hybrid events
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.

Before:

  # ./perf stat -M Kernel_Utilization -a sleep 1
WARNING: events in group from different hybrid PMUs!
WARNING: grouped events cpus do not match, disabling group:

b03b89b350 perf stat: Add user_time and system_time events
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 .
  72134524,ns,duration_time:u,72134524,100.00,,

c735b0a521 perf stat: Introduce stats for the user and system rusage times
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.
