  * ``PIPE_CAP_VERTEX_ELEMENT_SRC_OFFSET_4BYTE_ALIGNED_ONLY``: This CAP describes
    a hw limitation.  If true, pipe_vertex_element::src_offset must always be
    aligned to 4.  If false, there are no restrictions on src_offset.
 +* ``PIPE_CAP_COMPUTE``: Whether the implementation supports the
 +  compute entry points defined in pipe_context and pipe_screen.
+ * ``PIPE_CAP_USER_INDEX_BUFFERS``: Whether user index buffers are supported.
+   If not, the state tracker must upload all indices which are not in hw
+   resources.
+ * ``PIPE_CAP_USER_CONSTANT_BUFFERS``: Whether user constant buffers are
+   supported. If not, the state tracker must upload constants which are not in hw
