 The GIET_VM interrupt handler supports only the SOCLIB XCU interrupt controler. In a multi-cluster architectures, it must exist one XCU controller in all clusters containing processors. 
 
-Each multi-channel XCU component in a given cluster must contain (NB_PROCS_MAX * IRQ_PER_PROCESSOR) channels  (one channel = one output IRQ).
