perf test: Skip perf data type profiling tests for s390

2026-05-23T11:09:09+00:00

[ Upstream commit eb27e1c885ea75c1661188a548d100c8bce5970a ]

Test case 'perf data type profiling tests' fails on s390 with this
error:

  # ./perf mem record -- ./perf test -w code_with_type
  failed: no PMU supports the memory events
  # echo $?
  255
  #

because s390 does not support memory events at all. According to the
man page, perf annotate --code-with-type only works with memory
instructions only.  As command 'perf mem record ...' is not supported
on s390, skip this test for s390.

Output before:
 # ./perf test 'perf data type profiling tests'
 77: perf data type profiling tests                        : FAILED!

Output after:
 # ./perf test 'perf data type profiling tests'
 77: perf data type profiling tests                        : Skip

perf test type profiling: Remote typedef on struct

2026-05-23T11:09:08+00:00

[ Upstream commit 6910944bf0b92fea63d5a7aeed69e4b9c14fd01b ]

The typedef creates an issue where the struct or the typedef may
appear in the output and cause the "perf data type profiling tests" to
fail. Let's remove the typedef to keep the test passing.

perf test data_type_profiling.sh: Skip just the Rust tests if code_with_type workload is missing

2026-02-12T20:45:22+00:00

Namhyung suggested skipping only the rust tests when the code_with_type
'perf test' workload is not built into perf, do it so that we can
continue to test the C based workloads:

With rust:

  root@number:/# perf test -vv "data type"
   83: perf data type profiling tests:
  --- start ---
  test child forked, pid 2645245
  Basic Rust perf annotate test

  Basic C perf annotate test

  ---- end(0) ----
   83: perf data type profiling tests                                  : Ok

Without:

  root@number:/# perf test "data type"
   83: perf data type profiling tests                                  : Ok

perf tests: Test annotate with data type profiling and C

2026-02-08T22:16:28+00:00

Exercise the annotate command with data type profiling feature with C.

For that extend the existing data type profiling shell test to profile
the datasym workload, then annotate the result expecting to see some
data structures from the C code.
