+* The ⚠️ means that the data type is mostly supported, but there are some API tests, that do not work.
+   * The ``block_histogram`` test fails with ``int8``.
+   * The ``device_histogram`` and ``device_reduce_by_key`` doesn't work with ``rocprim::half`` and ``rocprim::bfloat16``.
+   * The ``device_run_length_encode``, ``warp_exchange`` and ``warp_load`` doesn't work with ``rocprim::half``.
