| * @page page_vsync_feedback_unstable_v1 The vsync_feedback_unstable_v1 protocol |
| * Protocol for providing vertical synchronization timing |
| * |
| * @section page_desc_vsync_feedback_unstable_v1 Description |
| * |
| * This protocol specifies a set of interfaces used to inform the client about |
| * vertical synchronization timing in a precise way and without unnecessary |
| * overhead. |
| * |
| * Warning! The protocol described in this file is experimental and backward |
| * incompatible changes may be made. Backward compatible changes may be added |
| * together with the corresponding interface version bump. Backward |
| * incompatible changes are done by bumping the version number in the protocol |
| * and interface names and resetting the interface version. Once the protocol |
| * is to be declared stable, the version number in the protocol is removed and |
| * the interface version number is reset. |
