Hi,
There are too many interrupts to respond to on my xavier board. I want to bind some of them from cpu0 to other cpus.
I have tested it by irq_set_affinity_hint()
, but it didn’t work.

hello 295839633,
please check # cat /proc/interrupts
, affinity can only be set at the GIC level.
affinity can be set separately for these two GPIO controllers (i.e. GPIO and AON-GPIO), which have separate GIC IRQs,
please check kernel init messages for the details of GPIO allocations.
for example, $ dmesg | grep "registered GPIOs"
besides,
please also check similar discussion thread as see-also.
thanks
