like, that's a whole roster. go read them too, iykyk πβ¨
lowkey reminder: the parent-interrupt family is big and every one of these does a different little job. irq_chip_ack_parent is just the acknowledge one. don't go expecting it to mask or unmask anything, that's not her job π
and that's the page, bestie π this whole thing lives under ./kernel/irq and it's dated October 2026 β so mark your calendar, irq_chip_ack_parent(9) is forever π₯ππ
