IRQ_SET_AFFINITY_NOT(9) Public Functions Provided IRQ_SET_AFFINITY_NOT(9)NAME
irq_set_affinity_notifier - control notification of IRQ affinity changes
SYNOPSIS
int irq_set_affinity_notifier(unsigned int irq, struct irq_affinity_notify * notify);
ARGUMENTS
irq
Interrupt for which to enable/disable notification
notify
Context for notification, or NULL to disable notification. Function pointers must be initialised; the other fields will be initialised
by this function.
DESCRIPTION
Must be called in process context. Notification may only be enabled after the IRQ is allocated and must be disabled before the IRQ is freed
using free_irq.
