Module kernel::irq::flags

Container for interrupt flags.

Constants

COND_SUSPEND

If the IRQ is shared with a NO_SUSPEND user, execute this interrupt handler after suspending interrupts. For system wakeup devices users need to implement wakeup detection in their interrupt handlers.

EARLY_RESUME

Resume IRQ early during syscore instead of at device resume time.

FORCE_RESUME

Force enable it on resume even if NO_SUSPEND is set.

IRQPOLL

Interrupt is used for polling (only the interrupt that is registered first in a shared interrupt is considered for performance reasons).

NOBALANCING

Flag to exclude this interrupt from irq balancing.

NO_AUTOEN

Don’t enable IRQ or NMI automatically when users request it. Users will enable it explicitly by enable_irq or enable_nmi later.

NO_DEBUG

Exclude from runnaway detection for IPI and similar handlers, depends on PERCPU.

NO_SUSPEND

Do not disable this IRQ during suspend. Does not guarantee that this interrupt will wake the system from a suspended state.

NO_THREAD

Interrupt cannot be threaded.

ONESHOT

Interrupt is not reenabled after the hardirq handler finished. Used by threaded interrupts which need to keep the irq line disabled until the threaded handler has been run.

PERCPU

Interrupt is per cpu.

PROBE_SHARED

Set by callers when they expect sharing mismatches to occur.

SHARED

Allow sharing the irq among several devices.

TIMER

Flag to mark this interrupt as timer interrupt.

TRIGGER_FALLING

The interrupt is triggered when the signal goes from high to low.

TRIGGER_HIGH

The interrupt is triggered while the signal is held high.

TRIGGER_LOW

The interrupt is triggered while the signal is held low.

TRIGGER_NONE

Use the interrupt line as already configured.

TRIGGER_RISING

The interrupt is triggered when the signal goes from low to high.
