Hi, Check: http://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#shared-state-cache
"... the build system detects changes in the "inputs" to a given task by creating a checksum (or signature) of the task's inputs. If the checksum changes, the system assumes the inputs have changed and the task needs to be rerun. For the second question, the shared state (sstate) code tracks which tasks add which output to the build process....
