Another type of query, ``PIPE_QUERY_TIME_ELAPSED``, returns the amount of time, in nanoseconds, the context takes to perform operations. +The result is an unsigned 64-bit integer. Gallium does not guarantee the availability of any query types; one must always check the capabilities of the :ref:`Screen` first. |
