	---help---
	  The Sync File Framework adds explicit syncronization via
	  userspace. It enables send/receive 'struct dma_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.

config SW_SYNC
	bool "Sync File Validation Framework"
	default n
	depends on SYNC_FILE
	depends on DEBUG_FS
	---help---
	  A sync object driver that uses a 32bit counter to coordinate
	  synchronization.  Useful when there is no hardware primitive backing
	  the synchronization.

WARNING: improper use of this can result in deadlocking kernel
	  drivers from userspace. Intended for test and debug only.
