The I915_TILING_* values in our uapi header are intended solely for use with the old get_tiling/set_tiling ioctls that operate on hardware de-tiling fences; all other uapi communication about tiling types is done via framebuffer modifiers rather than with these old values. On newer Intel platforms detiling fences no longer exist so the old get_tiling/set_tiling ioctls are no longer usable and will always return -EOPNOTSUPP. This means there's no reason to add new tiling types (such as the Tile4 format introduced by Xe_HP) to the uapi header here. Any kernel-internal code that needs to represent tiling format should either rely on framebuffer modifiers (as the display code does) or use some kind of non-uapi enum (as the GEM blt selftest now does).
