44 * IRQF_PROBE_SHARED - set by callers when they expect sharing mismatches to occur
45 * IRQF_TIMER - Flag to mark this interrupt as timer interrupt
46 * IRQF_PERCPU - Interrupt is per cpu
47 * IRQF_NOBALANCING - Flag to exclude this interrupt from irq balancing
48 * IRQF_IRQPOLL - Interrupt is used for polling (only the interrupt that is
51 * IRQF_ONESHOT - Interrupt is not reenabled after the hardirq handler finished.
54 * IRQF_NO_SUSPEND - Do not disable this IRQ during suspend. Does not guarantee
56 * state. See Documentation/power/suspend-and-interrupts.rst
57 * IRQF_FORCE_RESUME - Force enable it on resume even if IRQF_NO_SUSPEND is set
58 * IRQF_NO_THREAD - Interrupt cannot be threaded
59 * IRQF_EARLY_RESUME - Resume IRQ early during syscore instead of at device
61 * IRQF_COND_SUSPEND - If the IRQ is shared with a NO_SUSPEND user, execute this
65 * IRQF_NO_AUTOEN - Don't enable IRQ or NMI automatically when users request it.
68 * IRQF_NO_DEBUG - Exclude from runnaway detection for IPI and similar handlers,
92 * IRQC_IS_HARDIRQ - interrupt runs in hardirq context

103 * struct irqaction - per interrupt action descriptor
