SW_SYNC allows to run tests on the sync_file framework via debugfs on <debugfs>/sync/sw_sync Opening and closing the file triggers creation and release of a sync timeline. To create fences on this timeline the SW_SYNC_IOC_CREATE_FENCE ioctl should be used. To increment the timeline value use SW_SYNC_IOC_INC. Also it exports Sync information on <debugfs>/sync/info Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
