If the object is not 20 * naturally aligned, a padding field must be added. 21 * - Fields must be explicitly aligned to their natural type alignment with 22 * pad[0..N] fields. 23 * - All padding fields will be checked by the driver to make sure they are 24 * zeroed. 25 * - Flags can be added, but not removed/replaced. 26 * - New fields can be added to the main structures (the structures 27 * directly passed to the ioctl). Those fields can be added at the end of 28 * the structure, or replace existing padding fields. Any new field being 29 * added must preserve the behavior that existed before those fields were 30 * added when a value of zero is passed. 31 * - New fields can be added to indirect objects (objects pointed by the 32 * main structure), iff those objects are passed a size to reflect the 33 * size known by the userspace driver (see drm_panthor_obj_array::stride 34 * or drm_panthor_dev_query::size). 35 * - If the kernel driver is too old to know some fields, those will be 36 * ignored if zero, and otherwise rejected (and so will be zero on output). 37 * - If userspace is too old to know some fields, those will be zeroed 38 * (input) before the structure is parsed by the kernel driver. 39 * - Each new flag/field addition must come with a driver version update so 40 * the userspace driver doesn't have to trial and error to know which 41 * flags are supported. 42 * - Structures should not contain unions, as this would defeat the 43 * extensibility of such structures. 44 * - IOCTLs can't be removed or replaced. New IOCTL IDs should be placed 45 * at the end of the drm_panthor_ioctl_id enum. 46 */ 47 48 /** 49 * DOC: MMIO regions exposed to userspace. 50 * 51 * .. c:macro:: DRM_PANTHOR_USER_MMIO_OFFSET 52 * 53 * File offset for all MMIO regions being exposed to userspace.
