394 * struct drm_mode_get_connector - Get connector metadata.
396 * User-space can perform a GETCONNECTOR ioctl to retrieve information about a
397 * connector. User-space is expected to retrieve encoders, modes and properties
398 * by performing this ioctl at least twice: the first time to retrieve the
399 * number of elements, the second time to retrieve the elements themselves.
401 * To retrieve the number of elements, set @count_props and @count_encoders to
402 * zero, set @count_modes to 1, and set @modes_ptr to a temporary struct
403 * drm_mode_modeinfo element.
405 * To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr,
406 * @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and
407 * @count_encoders to their capacity.
409 * Performing the ioctl only twice may be racy: the number of elements may have
410 * changed with a hotplug event in-between the two ioctls. User-space is
411 * expected to retry the last ioctl until the number of elements stabilizes.
412 * The kernel won't fill any array which doesn't have the expected length.
414 * **Force-probing a connector**
416 * If the @count_modes field is set to zero and the DRM client is the current
417 * DRM master, the kernel will perform a forced probe on the connector to
418 * refresh the connector status, modes and EDID. A forced-probe can be slow,
419 * might cause flickering and the ioctl will block.
421 * User-space needs to force-probe connectors to ensure their metadata is
422 * up-to-date at startup and after receiving a hot-plug event. User-space
423 * may perform a forced-probe when the user explicitly requests it. User-space
424 * shouldn't perform a forced-probe in other situations.
