426  * struct drm_mode_get_connector - Get connector metadata.
427  *
428  * User-space can perform a GETCONNECTOR ioctl to retrieve information about a
429  * connector. User-space is expected to retrieve encoders, modes and properties
430  * by performing this ioctl at least twice: the first time to retrieve the
431  * number of elements, the second time to retrieve the elements themselves.
432  *
433  * To retrieve the number of elements, set @count_props and @count_encoders to
434  * zero, set @count_modes to 1, and set @modes_ptr to a temporary struct
435  * drm_mode_modeinfo element.
436  *
437  * To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr,
438  * @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and
439  * @count_encoders to their capacity.
440  *
441  * Performing the ioctl only twice may be racy: the number of elements may have
442  * changed with a hotplug event in-between the two ioctls. User-space is
443  * expected to retry the last ioctl until the number of elements stabilizes.
444  * The kernel won't fill any array which doesn't have the expected length.
445  *
446  * **Force-probing a connector**
447  *
448  * If the @count_modes field is set to zero and the DRM client is the current
449  * DRM master, the kernel will perform a forced probe on the connector to
450  * refresh the connector status, modes and EDID. A forced-probe can be slow,
451  * might cause flickering and the ioctl will block.
452  *
453  * User-space needs to force-probe connectors to ensure their metadata is
454  * up-to-date at startup and after receiving a hot-plug event. User-space
455  * may perform a forced-probe when the user explicitly requests it. User-space
456  * shouldn't perform a forced-probe in other situations.
