perf test: Fix arm64 perf_event_attr tests wrt --call-graph initialization
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' [...] Fixes: 7248e308a5758761 ("perf tools: Record ARM64 LR register automatically") Signed-off-by: German Gomez <german.gomez@arm.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexandre Truong <alexandre.truong@arm.com> Cc: Ian Rogers <irogers@google.com> Cc: James Clark <james.clark@arm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: John Fastabend <john.fastabend@gmail.com> Cc: KP Singh <kpsingh@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Martin KaFai Lau <kafai@fb.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Song Liu <songliubraving@fb.com> Cc: Yonghong Song <yhs@fb.com> Link: http://lore.kernel.org/lkml/20220125104435.2737-1-german.gomez@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
