[Mesa-dev] [PATCH 11/23] target-helpers: introduce dd_configuration()

[Emil Velikov]

Some drivers do not provide any configuration parameters
those are left as is. A handful of targets provide share_fd
(dmabuf) bug lack throttle. This patch provides the latter
in the cases where it was left out - ilo, nouveau and r300.
