249 * The mesa format name specification is as follows:

251 * There shall be 3 naming format base types: those for component array
252 * formats (type A); those for compressed formats (type C); and those for
253 * packed component formats (type P). With type A formats, color component
254 * order does not change with endianess. Each format name shall begin with
255 * MESA_FORMAT_, followed by a component label (from the Component Label
256 * list below) for each component in the order that the component(s) occur
257 * in the format, except for non-linear color formats where the first
258 * letter shall be 'S'. For type P formats, each component label is
259 * followed by the number of bits that represent it in the fundamental
260 * data type used by the format.
261 *
262 * Following the listing of the component labels shall be an underscore; a
263 * compression type followed by an underscore for Type C formats only; a
264 * storage type from the list below; and a bit with for type A formats,
265 * which is the bit width for each array element.

267 *
268 * ---------- Format Base Type A: Array ----------

279 * ---------- Format Base Type C: Compressed ----------
280 * MESA_FORMAT_[component list*][_*][compression type][storage type*]
281 * * where required

286 * MESA_FORMAT_LATC1_UNORM
287 * MESA_FORMAT_RGBA_FXT1
288 *
