imx8mm gpio interrupt could not bind from cpu0 to other

[sofia_0571]

too many interrupts(gpio5_3 as interrupt source) to respond. I want to bind from cpu0 to other cpus.

I have tested it by irq_set_affinity, but it didn’t work. 

last found chip->irq_set_affinity is null.now how to do it?

thanks.

Hi David

one can try to run application which uses that interrupt on specific core using examples with taskset :

in sect.6.9.4 AN12118  i.MX 8M Quad Power Consumption Measurement
