                        should start to delay EOI handling. Default is 2.

+                       Boolean parameter to disable using fifo event handling
+                       even if available. Normally fifo event handling is
+                       preferred over the 2-level event handling, as it is
+                       fairer and the number of possible event channels is
+                       much higher. Default is on (use fifo events).
