staging/android: make sync_timeline internal to sw_sync

2016-06-18T04:17:40+00:00

The only use sync_timeline will have in upstream kernel is for debugging
through the SW_SYNC interface. So make it internal to SW_SYNC to avoid
people use it in the future.

staging/android: bring struct sync_pt back

2016-06-18T04:17:40+00:00

Move the list_head members from sync_pt to struct fence was a mistake,
they will not be used by struct fence as planned before, so here we create
sync_pt again to bring the list heads back.

staging/android: remove size arg of sync_timeline_create()

2016-06-18T04:17:40+00:00

After we removed sw_sync_timeline this arg has not been really used by
anyone, all its users pass the size of struct sync_timeline there.

So simplify this function but not requiring the size anymore.

staging/android: remove struct sync_timeline_ops

2016-06-18T04:17:40+00:00

Move drv_name, the last field of sync_timeline_ops, to sync_timeline
and remove sync_timeline_ops.

struct sync_timeline_ops was just an extra abstraction on top of
fence_ops, and in the last few commits we removed all it ops in favor
of cleaner fence_ops.

staging/android: remove .{fence, timeline}_value_str() from timeline_ops

2016-06-18T04:17:40+00:00

Now that the value of fence and the timeline are not stored by sw_sync
anymore we can remove this extra abstraction to retrieve this data.

This patch changes both fence_ops (.fence_value_str and
.timeline_value_str) to return the str directly.

It also clean up struct sync_timeline_ops by removing both ops from there.

staging/android: store last signaled value on sync timeline

2016-06-18T04:17:40+00:00

Now fence timeline is aware of the last signaled fence, as it
receives the increment to the current value in sync_timeline_signal().

That allow us to remove .has_signaled() from timeline_ops as we can
directly compare using timeline->value and fence->seqno in sync.c
