/**
 * DOC: PowerVR UAPI
 *
 * The PowerVR IOCTL argument structs have a few limitations in place, in
 * addition to the standard kernel restrictions:
 *
 *  - All members must be type-aligned.
 *  - The overall struct must be padded to 64-bit alignment.
 *  - Explicit padding is almost always required. This takes the form of
 *    ``_padding_[x]`` members of sufficient size to pad to the next power-of-two
 *    alignment, where [x] is the offset into the struct in hexadecimal. Arrays
 *    are never used for alignment. Padding fields must be zeroed; this is
 *    always checked.
 *  - Unions may only appear as the last member of a struct.
 *  - Individual union members may grow in the future. The space between the
 *    end of a union member and the end of its containing union is considered
 *    "implicit padding" and must be zeroed. This is always checked.
 *
 * In addition to the IOCTL argument structs, the PowerVR UAPI makes use of
 * DEV_QUERY argument structs. These are used to fetch information about the
 * device and runtime. These structs are subject to the same rules set out
 * above.
 */

/**
 * struct drm_pvr_obj_array - Container used to pass arrays of objects
 *
 * It is not unusual to have to extend objects to pass new parameters, and the DRM
 * ioctl infrastructure is supporting that by padding ioctl arguments with zeros
 * when the data passed by userspace is smaller than the struct defined in the
 * drm_ioctl_desc, thus keeping things backward compatible. This type is just
 * applying the same concepts to indirect objects passed through arrays referenced
 * from the main ioctl arguments structure: the stride basically defines the size
 * of the object passed by userspace, which allows the kernel driver to pad with
 * zeros when it's smaller than the size of the object it expects.
 *
 * Use ``DRM_PVR_OBJ_ARRAY()`` to fill object array fields, unless you
 * have a very good reason not to.
