James Clark ac96f463cc perf tests: Remove bash constructs from stat_all_pmu.sh
The tests were passing but without testing and were printing the
following:

  $ ./perf test -v 90
  90: perf all PMU test                                               :
  --- start ---
  test child forked, pid 51650
  Testing cpu/branch-instructions/
  ./tests/shell/stat_all_pmu.sh: 10: [:
   Performance counter stats for 'true':

             137,307      cpu/branch-instructions/

         0.001376000 seconds user
         0.000000000 seconds sys: unexpected operator

Changing the regexes to a grep works in sh and prints this:

  $ ./perf test -v 90
  90: perf all PMU test                                               :

  test child finished with 0
  ---- end ----
  perf all PMU test: Ok

James Clark a9cdc1c5e3 perf tests: Remove bash construct from record+zstd_comp_decomp.sh
Commit 463538a383 ("perf tests: Fix test 68 zstd compression for
s390") inadvertently removed the -g flag from all platforms rather than
just s390, because the [[ ]] construct fails in sh. Changing to single
brackets restores testing of call graphs and removes the following error
from the output:

  $ ./perf test -v 85
  85: Zstd perf.data compression/decompression                        :

James Clark c8b947642d perf test: Remove bash construct from stat_bpf_counters.sh test
Currently the test skips with an error because == only works in bash:

  $ ./perf test 91 -v
  Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
  91: perf stat --bpf-counters test                                   :
  --- start ---
  test child forked, pid 44586
  ./tests/shell/stat_bpf_counters.sh: 26: [: -v: unexpected operator
  test child finished with -2
  ---- end ----
  perf stat --bpf-counters test: Skip

Changing == to = does the same thing, but doesn't result in an error:

  ./perf test 91 -v
  Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
  91: perf stat --bpf-counters test                                   :

  Skipping: --bpf-counters not supported
    Error: unknown option `bpf-counters'
  [...]
  test child finished with -2

Sohaib Mohamed 88e48238d5 perf bench futex: Fix memory leak of perf_cpu_map__new()
ASan reports memory leaks while running:

  $ sudo ./perf bench futex all

The leaks are caused by perf_cpu_map__new not being freed.
This patch adds the missing perf_cpu_map__put since it calls
cpu_map_delete implicitly.

Jiri Olsa 2a4898fc26 perf tools: Add more weak libbpf functions
We hit the window where perf uses libbpf functions, that did not make it
to the official libbpf release yet and it's breaking perf build with
dynamicly linked libbpf.

Fixing this by providing the new interface as weak functions which calls
the original libbpf functions. Fortunatelly the changes were just
renames.

Ian Rogers 4924b1f7c4 perf bpf: Avoid memory leak from perf_env__insert_btf()
perf_env__insert_btf() doesn't insert if a duplicate BTF id is
encountered and this causes a memory leak. Modify the function to return
a success/error value and then free the memory if insertion didn't
happen.

v2. Adds a return -1 when the insertion error occurs in
    perf_env__fetch_btf. This doesn't affect anything as the result is
    never checked.

Arnaldo Carvalho de Melo 7380aa8990 tools headers UAPI: Sync files changed by new futex_waitv syscall

  039c0ec9bb ("futex,x86: Wire up sys_futex_waitv()")

Namhyung Kim 9dc9855f18 perf arm-spe: Track task context switch for cpu-mode events
When perf report synthesize events from ARM SPE data, it refers to
current cpu, pid and tid in the machine.  But there's no place to set
them in the ARM SPE decoder.  I'm seeing all pid/tid is set to -1 and
user symbols are not resolved in the output.

  # perf record -a -e arm_spe_0/ts_enable=1/ sleep 1

  # perf report -q | head
     8.77%     8.77%  :-1      [kernel.kallsyms]  [k] format_decode
     7.02%     7.02%  :-1      [kernel.kallsyms]  [k] seq_printf
     7.02%     7.02%  :-1      [unknown]          [.] 0x0000ffff9f687c34
     5.26%     5.26%  :-1      [kernel.kallsyms]  [k] vsnprintf
     3.51%     3.51%  :-1      [kernel.kallsyms]  [k] string
     3.51%     3.51%  :-1      [unknown]          [.] 0x0000ffff9f66ae20
     3.51%     3.51%  :-1      [unknown]          [.] 0x0000ffff9f670b3c
     3.51%     3.51%  :-1      [unknown]          [.] 0x0000ffff9f67c040
     1.75%     1.75%  :-1      [kernel.kallsyms]  [k] ___cache_free
     1.75%     1.75%  :-1      [kernel.kallsyms]  [k] __count_memcg_events

Like Intel PT, add context switch records to track task info.  As ARM
SPE support was added later than PERF_RECORD_SWITCH_CPU_WIDE, I think
we can safely set the attr.context_switch bit and use it.

German Gomez 56c31cdff7 perf arm-spe: Implement find_snapshot callback
The head pointer of the AUX buffer managed by the arm_spe_pmu.c driver
is not monotonically increasing, therefore the find_snapshot callback is
needed in order to find the trace data within the AUX buffer and avoid
wasting space in the perf.data file.

The pointer is assumed to have wrapped if the buffer contains non-zero
data at the end. If it has wrapped, the entire contents of the AUX
buffer are stored in the perf.data file. Otherwise only the data up to
the head pointer is stored.

Ian Rogers 9aba0adae8 perf expr: Add source_count for aggregating events
Events like uncore_imc/cas_count_read/ on Skylake open multiple events
and then aggregate in the metric leader. To determine the average value
per event the number of these events is needed. Add a source_count
function that returns this value by counting the number of events with
the given metric leader. For most events the value is 1 but for
uncore_imc/cas_count_read/ it can yield values like 6.

Add a generic test, but manually tested with a test metric that uses
the function.

Ian Rogers df2252054e perf test: Make each test/suite its own struct.
By switching to an array of pointers to tests (later to be suites)
the definition of the tests can be moved to the file containing the
tests.

Committer notes:

It's "&vectors_page", not "&vectors_pages", noticed when cross building
to 32-bit ARM.

Also the DEFINE_SUITE(vectors_page) should be done where its function is
implemented, in tools/perf/arch/arm/tests/vectors-page.c, so that we can
make it static, as we don't have anymore its declaration in tests.h.
