And in some places libtraceevent is available, but then:

  73     6.88 ubuntu:22.04                  : FAIL gcc version 11.3.0 (Ubuntu 11.3.0-1ubuntu1~22.04)
    /git/perf-6.1.0-rc6/tools/perf/util/evsel.c: In function ‘evsel__rawptr’:
    /git/perf-6.1.0-rc6/tools/perf/util/evsel.c:2787:36: error: ‘TEP_FIELD_IS_RELATIVE’ undeclared (first use in this function); did you mean ‘TEP_FIELD_IS_FLAG’?
     2787 |                 if (field->flags & TEP_FIELD_IS_RELATIVE)
          |                                    ^~~~~~~~~~~~~~~~~~~~~
          |                                    TEP_FIELD_IS_FLAG

Still need to look how to cover these.
