 Regarding the allocation of interrupts to processors (IRQ routing using the XCU_MASK registers), the GIET-VM implement the following policy ('''lpid''' is the local processor index, between 0 and 7):
- 1. The GIET-VM uses only one XCU output IRQ per processor  (with index = lpid * IRQ_PER_PROCESSOR), even if the hardware platform contains more than one IRQ_PER_PROCESSOR.
+ 1. The GIET-VM uses only one XCU output IRQ per processor  (with index = lpid * IRQ_PER_PROCESSOR), even if the hardware platform connect more than one IRQ line for each processor.
 
  2. In each cluster the local '''HWI'''  generated by the local peripherals are ''statically'' allocated and distributed to local processors, to share the load between all processors).
