Perhaps this is more a Linux kernel question, but does the Jetson TX2 support nested interrupts by default (I am using Linux kernel 4.4.38 from the Jetpack 3.1 download)? For example, if I am handling a GPIO interrupt (on CPU0), and a different GPIO interrupt occurs during the first ISR, will it preempt the interrupt handler? Or would the CPU0 timer that fires every 4ms (every jiffy), interrupt my ISR if it was to happen immediately after the GPIO interrupt?
If this is the case, would it be harmful (or bad practice), to disable local interrupts in my ISR if I need something to execute without being interrupted?
