@ -440,3 +440,15 @@ get_timestamp
Query a timestamp in nanoseconds. The returned value should match
PIPE_QUERY_TIMESTAMP. This function returns immediately and doesn't
wait for rendering to complete (which cannot be achieved with queries).
get_driver_query_info
^^^^^^^^^^^^^^^^^^^^^
Return a driver-specific query. If the **info** parameter is NULL,
the number of available queries is returned. Otherwise, the driver
query at the specified **index** is returned in **info**.
The function returns non-zero on success.
The driver-specific query is described with the pipe_driver_query_info
structure.
