    perf test: Fix arm64 perf_event_attr tests wrt --call-graph initialization · 047e6032
    German Gomez authored
    The struct perf_event_attr is initialised differently in Arm64 when
    recording in call-graph fp mode, so update the relevant tests, and add
    two extra arm64-only tests.
    
    Before:
    
      $ perf test 17 -v
      17: Setup struct perf_event_attr
      [...]
      running './tests/attr/test-record-graph-default'
      expected sample_type=295, got 4391
      expected sample_regs_user=0, got 1073741824
      FAILED './tests/attr/test-record-graph-default' - match failure
      test child finished with -1
      ---- end ----
    
    After:
    
    [...]
      running './tests/attr/test-record-graph-default-aarch64'
      test limitation 'aarch64'
      running './tests/attr/test-record-graph-fp-aarch64'
      test limitation 'aarch64'
      running './tests/attr/test-record-graph-default'
      test limitation '!aarch64'
      excluded architecture list ['aarch64']
      skipped [aarch64] './tests/attr/test-record-graph-default'
      running './tests/attr/test-record-graph-fp'
      test limitation '!aarch64'
      excluded architecture list ['aarch64']
      skipped [aarch64] './tests/attr/test-record-graph-fp'
    [...]
