+ * sys_perf_event_open function.
+ *
+ * The general idea is to store 'struct perf_event_attr' details for
+ * each event created within single perf command. Each event details
+ * are stored into separate text file. Once perf command is finished
+ * these files can be checked for values we expect for command.
+ *
+ * Besides 'struct perf_event_attr' values we also store 'fd' and
+ * 'group_fd' values to allow checking for groups created.
+ *
+ * This all is triggered by setting PERF_TEST_ATTR environment variable.
+ * It must contain name of existing directory with access and write
+ * permissions. All the event text files are stored there.

+The struct perf_event_attr test (attr tests) support
+====================================================
+This testing support is embedded into perf directly and is governed
+by the PERF_TEST_ATTR environment variable and hook inside the
+sys_perf_event_open function.
+
+The general idea is to store 'struct perf_event_attr' details for
+each event created within single perf command. Each event details
+are stored into separate text file. Once perf command is finished
+these files are checked for values we expect for command.
+
+The attr tests consist of following parts:
+
+tests/attr.c
+------------
+This is the sys_perf_event_open hook implementation. The hook
+is triggered when the PERF_TEST_ATTR environment variable is
+defined. It must contain name of existing directory with access
+and write permissions.
+
+For each sys_perf_event_open call event details are stored in
+separate file. Besides 'struct perf_event_attr' values we also
+store 'fd' and 'group_fd' values to allow checking for groups.
+
+tests/attr.py
+-------------
+This is the python script that does all the hard work. It reads
+the test definition, executes it and checks results.
+
+tests/attr/
+-----------
+Directory containing all attr test definitions.
+Following tests are defined (with perf commands):
+
+ perf record kill (test-record-basic)
+ perf record -b kill (test-record-branch-any)
+ perf record -j any kill (test-record-branch-filter-any)
+ perf record -j any_call kill (test-record-branch-filter-any_call)
+ perf record -j any_ret kill (test-record-branch-filter-any_ret)
+ perf record -j hv kill (test-record-branch-filter-hv)
+ perf record -j ind_call kill (test-record-branch-filter-ind_call)
+ perf record -j k kill (test-record-branch-filter-k)
+ perf record -j u kill (test-record-branch-filter-u)
+ perf record -c 123 kill (test-record-count)
+ perf record -d kill (test-record-data)
+ perf record -F 100 kill (test-record-freq)
+ perf record -g kill (test-record-graph-default)
+ perf record -g kill (test-record-graph-default-aarch64)
+ perf record --call-graph dwarf kill (test-record-graph-dwarf)
+ perf record --call-graph fp kill (test-record-graph-fp)
+ perf record --call-graph fp kill (test-record-graph-fp-aarch64)
+ perf record --group -e cycles,instructions kill (test-record-group)
+ perf record -e '{cycles,instructions}' kill (test-record-group1)
+ perf record -e '{cycles/period=1/,instructions/period=2/}:S' kill (test-record-group2)
+ perf record -D kill (test-record-no-delay)
+ perf record -i kill (test-record-no-inherit)
+ perf record -n kill (test-record-no-samples)
+ perf record -c 100 -P kill (test-record-period)
+ perf record -c 1 --pfm-events=cycles:period=2 (test-record-pfm-period)
