153 +=== Deadlock Prevention ===
154 +
155 +* When attempting to reserve more than one segment (Entering a station, passing a junction) a separate protocol for deadlock prevention must be adhered to.
156 +* In each tick the controller must check if only partial permissions were granted.
157 +* If partial permission was granted the train waits for one tick and releases all locks.
158 +* In the following tick the locks are requested again.
159 +* As a special case the controllers passing through KIO_LN_0 or KIO_LN_1 must wait an additional tick after releasing the requests.
160 +* A sample controller can be found in the repository at [[/doc/deadlocks/resolve_deadlock.sct>>url:https://git.rtsys.informatik.uni-kiel.de/projects/PRAK/repos/14ss-railway/browse/doc/deadlocks/resolve_deadlock.sct||shape="rect"]]
