staging : android : sync : get_unused_fd

2014-09-29T02:03:57Z

sync.h recommends to use get_unused_fd which does not set O_CLOEXEC while the rest of the android tree uses get_unused_fd_flags and sets O_CLOEXEC. The patch adjust the comment. Signed-off-by: Heinrich Schuchardt 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.

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

2013-03-04T09:44:07Z
