++/**
++ * DOC: overview
++ *
++ * In the DRM subsystem, framebuffer pixel formats are described using the
++ * fourcc codes defined in `include/uapi/drm/drm_fourcc.h`. In addition to the
++ * fourcc code, a Format Modifier may optionally be provided, in order to
++ * further describe the buffer's format - for example tiling or compression.
++ *
++ * Format Modifiers
++ * ----------------
++ *
++ * Format modifiers are used in conjunction with a fourcc code, forming a
++ * unique fourcc:modifier pair. This format:modifier pair must fully define the
++ * format and data layout of the buffer, and should be the only way to describe
++ * that particular buffer.
++ *
++ * Having multiple fourcc:modifier pairs which describe the same layout should
++ * be avoided, as such aliases run the risk of different drivers exposing
++ * different names for the same data format, forcing userspace to understand
++ * that they are aliases.
++ *
++ * Format modifiers may change any property of the buffer, including the number
++ * of planes and/or the required allocation size. Format modifiers are
++ * vendor-namespaced, and as such the relationship between a fourcc code and a
++ * modifier is specific to the modifer being used. For example, some modifiers
++ * may preserve meaning - such as number of planes - from the fourcc code,
++ * whereas others may not.
++ *
++ * Modifiers must uniquely encode buffer layout. In other words, a buffer must
++ * match only a single modifier. A modifier must not be a subset of layouts of
++ * another modifier. For instance, it's incorrect to encode pitch alignment in
++ * a modifier: a buffer may match a 64-pixel aligned modifier and a 32-pixel
++ * aligned modifier. That said, modifiers can have implicit minimal
++ * requirements.
++ *
++ * For modifiers where the combination of fourcc code and modifier can alias,
++ * a canonical pair needs to be defined and used by all drivers. Preferred
++ * combinations are also encouraged where all combinations might lead to
++ * confusion and unnecessarily reduced interoperability. An example for the
++ * latter is AFBC, where the ABGR layouts are preferred over ARGB layouts.
++ *
++ * There are two kinds of modifier users:
++ *
++ * - Kernel and user-space drivers: for drivers it's important that modifiers
++ * don't alias, otherwise two drivers might support the same format but use
++ * different aliases, preventing them from sharing buffers in an efficient
++ * format.
++ * - Higher-level programs interfacing with KMS/GBM/EGL/Vulkan/etc: these users
++ * see modifiers as opaque tokens they can check for equality and intersect.
++ * These users musn't need to know to reason about the modifier value
++ * (i.e. they are not expected to extract information out of the modifier).
++ *
++ * Vendors should document their modifier usage in as much detail as
++ * possible, to ensure maximum compatibility across devices, drivers and
++ * applications.
++ *
++ * The authoritative list of format modifier codes is found in
++ * `include/uapi/drm/drm_fourcc.h`

++ * 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
++ * up-to-date at startup and after receiving a hot-plug event. User-space
++ * may perform a forced-probe when the user explicitly requests it. User-space
++ * shouldn't perform a forced-probe in other situations.
