This capability allows IO-APIC-dependent code to be included. config ARCV2_INTERRUPT_UNIT bool "ARCv2 Interrupt Unit" default y depends on ARC help The ARCv2 interrupt unit has 16 allocated exceptions associated with vectors 0 to 15 and 240 interrupts associated with vectors 16 to 255. The interrupt unit is optional in the ARCv2-based processors. When building a processor, you can configure the processor to include an interrupt unit. The ARCv2 interrupt unit is highly programmable. endmenu
