| 17 | * DOC: PowerVR UAPI | ||
| 18 | * | ||
| 19 | * The PowerVR IOCTL argument structs have a few limitations in place, in | ||
| 20 | * addition to the standard kernel restrictions: | ||
| 21 | * | ||
| 22 | * - All members must be type-aligned. | ||
| 23 | * - The overall struct must be padded to 64-bit alignment. | ||
| 24 | * - Explicit padding is almost always required. This takes the form of | ||
| 25 | * ``_padding_[x]`` members of sufficient size to pad to the next power-of-two | ||
| 26 | * alignment, where [x] is the offset into the struct in hexadecimal. Arrays | ||
| 27 | * are never used for alignment. Padding fields must be zeroed; this is | ||
| 28 | * always checked. | ||
| 29 | * - Unions may only appear as the last member of a struct. | ||
| 30 | * - Individual union members may grow in the future. The space between the | ||
| 31 | * end of a union member and the end of its containing union is considered | ||
| 32 | * "implicit padding" and must be zeroed. This is always checked. | ||
| 33 | * | ||
| 34 | * In addition to the IOCTL argument structs, the PowerVR UAPI makes use of | ||
| 35 | * DEV_QUERY argument structs. These are used to fetch information about the | ||
| 36 | * device and runtime. These structs are subject to the same rules set out | ||
| 37 | * above. | ||

| 42 | * | ||
| 43 | * It is not unusual to have to extend objects to pass new parameters, and the DRM | ||
| 44 | * ioctl infrastructure is supporting that by padding ioctl arguments with zeros | ||
| 45 | * when the data passed by userspace is smaller than the struct defined in the | ||
| 46 | * drm_ioctl_desc, thus keeping things backward compatible. This type is just | ||
| 47 | * applying the same concepts to indirect objects passed through arrays referenced | ||
| 48 | * from the main ioctl arguments structure: the stride basically defines the size | ||
| 49 | * of the object passed by userspace, which allows the kernel driver to pad with | ||
| 50 | * zeros when it's smaller than the size of the object it expects. | ||

| 53 | * have a very good reason not to. | ||
