staging/android: move trace/sync.h to sync_trace.h

2016-08-15T14:39:45Z

The common behaviour for trace headers is to have them in the same folder they are used, instead of creating a special trace/ directory. Signed-off-by: Gustavo Padovan Reviewed-by: Eric Engestrom Signed-off-by: Greg Kroah-Hartman

staging/android: rename sync.h to sync_debug.h

2016-06-18T04:17:40Z

This header file only contains information for debugging and SW_SYNC, so rename it to sync_debug.h instead of having a more generic name. Signed-off-by: Gustavo Padovan Reviewed-by: Daniel Vetter Reviewed-by: Sumit Semwal Signed-off-by: Greg Kroah-Hartman

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

2016-06-18T04:17:40Z

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: remove SYNC_WAIT ioctl

2016-02-08T01:34:58Z

This ioctl is replicating the work of poll() syscall so let's take the opportunity that this is still on staging tree and remove the duplication and force new users to use the poll() standard interface. Signed-off-by: Gustavo Padovan Signed-off-by: Greg Kroah-Hartman

staging/android: remove struct sync_pt

2016-02-08T01:34:58Z

struct sync_pt was just wrapping around struct fence and creating an extra abstraction layer. The only two members of struct sync_pt, child_list and active_list, were moved to struct fence in an earlier commit. After removing those two members struct sync_pt is nothing more than struct fence, so remove it all and use struct fence directly.

staging/android: rename sync_fence to sync_file

2016-02-08T01:34:58Z

sync_file has a more close meaning to what a sync_fence really, a struct that represent a file that can be used by userspace to get information on a fence, or wait for it to be signaled. Signed-off-by: Gustavo Padovan Reviewed-by: Maarten Lankhorst Signed-off-by: Greg Kroah-Hartman

android: convert sync to fence api, v6

2014-07-08T20:28:26Z

Just to show it's easy. Android syncpoints can be mapped to a timeline. This removes the need to maintain a separate api for synchronization. I've left the android trace events in place, but the core fence events should already be sufficient for debugging. v2: - Call fence_remove_callback in sync_fence_free if not all fences have fired. v3: - Merge Colin Cross' bugfixes, and the android fence merge optimization. v4: - Merge with the upstream fixes. v5: - Fix small style issues pointed out by Thomas Hellstrom. v6: - Fix for updates to fence api.
