WebDec 10, 2024 · The request_irq and irq_set_irq_type seemed to be ok with 0 return. But when I used irq_get_irq_type, it always returned 0. the interrupt number is 16 . The following /proc/interrupt/ showed it didn't change its trigger type. WebThe approach here is to use PDC interrupt at all times (while keeping the GPIO irq disabled). The PDC interrupt handler invokes the action handler of the GPIO IRQ instead. This allows us to avoid interrupt hand-offs while entering idle states and keeps things very simple.
