^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) * In the DRM subsystem, framebuffer pixel formats are described using the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) * fourcc codes defined in `include/uapi/drm/drm_fourcc.h`. In addition to the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) * fourcc code, a Format Modifier may optionally be provided, in order to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) * further describe the buffer's format - for example tiling or compression.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) * Format Modifiers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) * ----------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) * Format modifiers are used in conjunction with a fourcc code, forming a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) * unique fourcc:modifier pair. This format:modifier pair must fully define the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) * format and data layout of the buffer, and should be the only way to describe
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) * that particular buffer.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) * Having multiple fourcc:modifier pairs which describe the same layout should
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) * be avoided, as such aliases run the risk of different drivers exposing
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) * different names for the same data format, forcing userspace to understand
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) * that they are aliases.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) * Format modifiers may change any property of the buffer, including the number
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) * of planes and/or the required allocation size. Format modifiers are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56) * vendor-namespaced, and as such the relationship between a fourcc code and a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) * modifier is specific to the modifer being used. For example, some modifiers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58) * may preserve meaning - such as number of planes - from the fourcc code,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) * whereas others may not.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 60) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 61) * Vendors should document their modifier usage in as much detail as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 62) * possible, to ensure maximum compatibility across devices, drivers and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 63) * applications.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 64) *
