42 * These flags used only by the kernel as part of the
43 * irq handling routines.
44 *
45 * IRQF_DISABLED - keep irqs disabled when calling the action handler.
46 * DEPRECATED. This flag is a NOOP and scheduled to be removed
47 * IRQF_SAMPLE_RANDOM - irq is used to feed the random generator
48 * IRQF_SHARED - allow sharing the irq among several devices
49 * IRQF_PROBE_SHARED - set by callers when they expect sharing mismatches to occur
50 * IRQF_TIMER - Flag to mark this interrupt as timer interrupt
51 * IRQF_PERCPU - Interrupt is per cpu
52 * IRQF_NOBALANCING - Flag to exclude this interrupt from irq balancing
53 * IRQF_IRQPOLL - Interrupt is used for polling (only the interrupt that is
54 * registered first in an shared interrupt is considered for
55 * performance reasons)
56 * IRQF_ONESHOT - Interrupt is not reenabled after the hardirq handler finished.
57 * Used by threaded interrupts which need to keep the
58 * irq line disabled until the threaded handler has been run.
59 * IRQF_NO_SUSPEND - Do not disable this IRQ during suspend
60 * IRQF_FORCE_RESUME - Force enable it on resume even if IRQF_NO_SUSPEND is set
61 * IRQF_NO_THREAD - Interrupt cannot be threaded
62 * IRQF_EARLY_RESUME - Resume IRQ early during syscore instead of at device
63 * resume time.
