interrupt total rate intc0,2: vchiq0 2 0 intc0,11: systimer0 30942515 1121 intc0,17: + 663141573 24032 intc0,28: bcm_dma0 564264 20 intc0,61: iichb0 104 0 intc0,65: uart0 233 0 intc0,70: + 63590 2 Total 694712281 25176 It has a rather high trigger rate, but only a plus designator. Could be USB related as, of course, it has network traffic. However, the interrupt 17 is listed in the DMA controller: bcm_dma0: <BCM2835 DMA Controller> mem 0x7e007000-0x7e007eff irq 4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19 on simplebus0 70, which has a rather low rate, isn't listed in dmesg at all. devinfo -rv doesn't list Interrupt 17 at all. It does list 0x17 for uart0, but uart0 shouldn't have a high rate and I assume vmstat -i to list decimal interrupt numbers. This is on a Wandboard-Quad: interrupt total rate gic0,p13: mp_tmr0 218100482 635 gic0,s22: + 16577830 48 gic0,s24: + 16583271 48 gic0,s26: uart0 144 0 gic0,s40: ehci1 4400211 13 gic0,s66: gpio0 935315 3 gpio0,6: ffec0 935315 3 cpu0:rendezvous 1125454 3 cpu1:rendezvous 1085171 3 cpu2:rendezvous 1101109 3 cpu3:rendezvous 1111276 3 cpu0:ast 54 0 cpu1:ast 98 0 cpu2:ast 76 0 cpu3:ast 94 0 cpu0:preempt 5775713 17 cpu1:preempt 8540039 25 cpu2:preempt 7938877 23 cpu3:preempt 8334248 24 cpu0:hardclock 36400 0 Total 292581177 852 Also some mysterios plus interrupts, but non with such a high rate. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
