/**
* 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`
