It enables send/receive 'struct fence' objects to/from 11 userspace via Sync File fds for synchronization between drivers via 12 userspace components. It has been ported from Android. 13 14 The first and main user for this is graphics in which a fence is 15 associated with a buffer. When a job is submitted to the GPU a fence 16 is attached to the buffer and is transferred via userspace, using Sync 17 Files fds, to the DRM driver for example.
