/**
 * 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.
 *
 * 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`
