 393  * struct drm_mode_get_connector - Get connector metadata.
 394  *
 395  * User-space can perform a GETCONNECTOR ioctl to retrieve information about a
 396  * connector. User-space is expected to retrieve encoders, modes and properties
 397  * by performing this ioctl at least twice: the first time to retrieve the
 398  * number of elements, the second time to retrieve the elements themselves.
 399  *
 400  * To retrieve the number of elements, set @count_props and @count_encoders to
 401  * zero, set @count_modes to 1, and set @modes_ptr to a temporary struct
 402  * drm_mode_modeinfo element.
 403  *
 404  * To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr,
 405  * @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and
 406  * @count_encoders to their capacity.
 407  *
 408  * Performing the ioctl only twice may be racy: the number of elements may have
 409  * changed with a hotplug event in-between the two ioctls. User-space is
 410  * expected to retry the last ioctl until the number of elements stabilizes.
 411  * The kernel won't fill any array which doesn't have the expected length.
 412  *
 413  * **Force-probing a connector**
 414  *
 415  * If the @count_modes field is set to zero, the kernel will perform a forced
 416  * probe on the connector to refresh the connector status, modes and EDID.
 417  * A forced-probe can be slow and the ioctl will block. A force-probe can cause
 418  * flickering and temporary freezes, so it should not be performed
 419  * automatically.
 420  *
 421  * User-space shouldn't need to force-probe connectors in general: the kernel
 422  * will automatically take care of probing connectors that don't support
 423  * hot-plug detection when appropriate. However, user-space may force-probe
 424  * connectors on user request (e.g. clicking a "Scan connectors" button, or
 425  * opening a UI to manage screens).
