In userspace we can use drmGetConnector() or drmGetConnectorCurrent() in order to retrieve connector information. The difference between both is that the former retrieves the complete set of modes and encoders associated with the connector, while the latter only retrieves the currently known set of modes and encoders - but is much faster.
This performance improvement is the reason why userspace applications may prefer to use drmGetConnectorCurrent() when they need to retrieve information from a device.
We discussed with Daniel Vetter and it turns out user-space should always use drmGetConnector(). See [1].
Hi,
where is the discussion?
Please record the justitication for that patch in its commit message. "Can't" does not explain anything.
Thanks, pq
