+/**
+ * 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.
