/**
|
|
* struct drm_mode_get_connector - Get connector metadata.
|
|
*
|
|
* User-space can perform a GETCONNECTOR ioctl to retrieve information about a
|
|
* connector. User-space is expected to retrieve encoders, modes and properties
|
|
* by performing this ioctl at least twice: the first time to retrieve the
|
|
* number of elements, the second time to retrieve the elements themselves.
|
|
*
|
|
* To retrieve the number of elements, set @count_props and @count_encoders to
|
|
* zero, set @count_modes to 1, and set @modes_ptr to a temporary struct
|
|
* drm_mode_modeinfo element.
|
|
*
|
|
* To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr,
|
|
* @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and
|
|
* @count_encoders to their capacity.
|
|
*
|
|
* Performing the ioctl only twice may be racy: the number of elements may have
|
|
* changed with a hotplug event in-between the two ioctls. User-space is
|
|
* expected to retry the last ioctl until the number of elements stabilizes.
|
|
* The kernel won't fill any array which doesn't have the expected length.
|
|
*
|
|
* **Force-probing a connector**
|
|
*
|
|
* If the @count_modes field is set to zero and the DRM client is the current
|
|
* DRM master, the kernel will perform a forced probe on the connector to
|
|
* refresh the connector status, modes and EDID. A forced-probe can be slow,
|
|
* might cause flickering and the ioctl will block.
|
|
*
|
|
* User-space needs to force-probe connectors to ensure their metadata is

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