staging: sync: Refactor sync debug printing

2013-03-04T09:46:55Z

Move driver callbacks to fill strings instead of using seq_files. This will allow those values to be used in a future tracepoint patch.

staging: sync: Add reference counting to timelines

2013-03-04T09:44:07Z

If a timeline is destroyed while fences still hold pts on it, the reworked fence release handler can cause the timeline to be freed before all it's points are freed.

staging: sync: Add internal refcounting to fences

2013-03-04T09:44:07Z

If a fence is released while a timeline that one of it's pts is on is being signaled, it is possible for that fence to be deleted before it is signaled. This patch adds a refcount for internal references such as signaled pt processing.

staging: sync: Allow async waits to be canceled

2013-03-04T09:40:09Z

In order to allow drivers to cleanly handled teardown we need to allow them to cancel pending async waits. To do this cleanly, we move allocation of sync_fence_waiter to the driver calling sync_async_wait().

staging: sync: Add synchronization framework

2013-03-04T09:40:07Z

Sync is a framework for synchronization between multiple drivers. Sync implementations can take advantage of hardware synchronization built into devices like GPUs.
