| The Sync File Framework adds explicit syncronization via |
| userspace. It enables send/receive 'struct fence' objects to/from |
| userspace via Sync File fds for synchronization between drivers via |
| userspace components. It has been ported from Android. |
| |
| The first and main user for this is graphics in which a fence is |
| associated with a buffer. When a job is submitted to the GPU a fence |
| is attached to the buffer and is transferred via userspace, using Sync |
| Files fds, to the DRM driver for example. More details at |
| Documentation/sync_file.txt. |
