Spurious headphone detection interrupts
#5
I think it's odd that all 6 are on CPU0. If you leave it go longer, are they always on CPU0?

Frankly though, I don't know anything about interrupt control on this SOC, so maybe there's a reasonable explanation for this.

Here's what I get. I see something completely different. I don't see an IRQ 73 at all. Please upload your full results.

Code:
pbp$ intrctl list interrupt id CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 device name(s) gicv3 irq 0 32015* 31202* 27700* 31835* 181838* 148091* IPI ast gicv3 irq 1 364* 385* 342* 361* 305* 178* IPI xcall gicv3 irq 2 0* 0* 0* 0* 0* 0* IPI nop gicv3 irq 3 0* 0* 0* 0* 0* 0* IPI shootdown gicv3 irq 4 0* 0* 0* 0* 0* 0* IPI ddb gicv3 irq 5 64038* 254* 303* 406* 376* 273* IPI generic gicv3 irq 23 0* 0* 0* 0* 0* 0* gicv3 irq 27 42431* 42375* 42375* 42376* 42371* 42372* gicv3 irq 43 37760* 0 0 0 0 0 gicv3 irq 58 0* 2* 0* 0* 0* 0* gicv3 irq 60 253* 311* 269* 240* 239* 223* gicv3 irq 62 9* 10* 5* 6* 5* 8* gicv3 irq 64 0* 0* 0* 0* 0* 0* gicv3 irq 72 0* 0* 0* 0* 0* 0* gicv3 irq 96 6* 0 0 0 0 0 gicv3 irq 97 0* 0 0 0 0 0 gicv3 irq 129 0* 0* 0* 0* 0* 0* gicv3 irq 131 0* 1* 0* 0* 0* 0* gicv3 irq 132 0* 0* 0* 0* 0* 0* gicv3 irq 137 0* 0* 0* 0* 0* 0* gicv3 irq 142 21885* 25409* 23693* 22990* 22501* 22202*

Incidentally, this is after about ten minutes of uptime.
