PS interrupt setup in 2014.x
The note attached to the interrupt setup tick box is misleading:
It gives an incorrect idea of what is happening

PS7 source files
Two auto-generated source files are now of interest:
– Dev_processing_system7_0_0.v is a wrapper for
– Processing_system7_v5_4_processing_system7.v

C_IRQ_F2P_MODE
This is a new parameter introduced in
2014.x.
It is assigned a value in
Dev_processing_system7_0_0.v and passed to
Processing_system7_v5_4_processing_system7.v
The parameter value passed is “DIRECT”.

Generated PS source file in 2014.x
The “DIRECT” parameter is now used in mapping the interrupt
vector IRQ_F2P to the internal interrupt vector irq_f2p_i
