Gustavo Padovan31954662016-05-31 11:33:16 -03009 The Sync File Framework adds explicit syncronization via
10 userspace. 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. More details at
18 Documentation/sync_file.txt.
