425/**
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.

670 * struct drm_mode_fb_cmd2 - Frame-buffer metadata.
671 *
672 * This struct holds frame-buffer metadata. There are two ways to use it:
673 *
674 * - User-space can fill this struct and perform a &DRM_IOCTL_MODE_ADDFB2
675 * ioctl to register a new frame-buffer. The new frame-buffer object ID will
676 * be set by the kernel in @fb_id.
677 * - User-space can set @fb_id and perform a &DRM_IOCTL_MODE_GETFB2 ioctl to
678 * fetch metadata about an existing frame-buffer.
679 *
680 * In case of planar formats, this struct allows up to 4 buffer objects with
681 * offsets and pitches per plane. The pitch and offset order are dictated by
682 * the format FourCC as defined by ``drm_fourcc.h``, e.g. NV12 is described as:
683 *
684 * YUV 4:2:0 image with a plane of 8-bit Y samples followed by an
685 * interleaved U/V plane containing 8-bit 2x2 subsampled colour difference
686 * samples.
687 *
688 * So it would consist of a Y plane at ``offsets[0]`` and a UV plane at
689 * ``offsets[1]``.
690 *
691 * To accommodate tiled, compressed, etc formats, a modifier can be specified.
692 * For more information see the "Format Modifiers" section. Note that even
693 * though it looks like we have a modifier per-plane, we in fact do not. The
694 * modifier for each plane must be identical. Thus all combinations of
695 * different data layouts for multi-plane formats must be enumerated as
696 * separate modifiers.
697 *
698 * All of the entries in @handles, @pitches, @offsets and @modifier must be
699 * zero when unused. Warning, for @offsets and @modifier zero can't be used to
700 * figure out whether the entry is used or not since it's a valid value (a zero
701 * offset is common, and a zero modifier is &DRM_FORMAT_MOD_LINEAR).
