MEMBERS
irq
- interrupt number for this descriptor
timer_rand_state
- pointer to timer rand state struct
kstat_irqs
- irq stats per cpu
irq_2_iommu
- iommu with this irq
handle_irq
- highlevel irq-events handler [if NULL, __do_IRQ]
chip
- low level interrupt hardware access
msi_desc
- MSI descriptor
handler_data
- per-IRQ data for the irq_chip methods
chip_data
- platform-specific per-chip private data for the chip methods, to allow shared chip implementations
action
- the irq action chain
status
- status information
depth
- disable-depth, for nested irq_disable calls
wake_depth
- enable depth, for multiple set_irq_wake callers
irq_count
- stats field to detect stalled irqs
last_unhandled
- aging timer for unhandled count
irqs_unhandled
- stats field for spurious unhandled interrupts
lock
- locking for SMP
affinity
- IRQ affinity on SMP
node
- node index useful for balancing
pending_mask
- pending rebalanced interrupts
threads_active
- number of irqaction threads currently running
wait_for_threads
- wait queue for sync_irq to wait for threaded handlers
dir
- /proc/irq/ procfs entry
name
- flow handler name for /proc/interrupts output
