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.
