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` ++ */ ++
