NAME
tapset::irq - Systemtap probes for IRQ, workqueue,etcDESCRIPTION
Probe points for probing irq handler execution, softirqs, workqueues,etc
- workqueue.create
- probes creation of a new workqueue
Arguments:
wq_thread
task_struct of the workqueue thread.cpu
cpu for which the worker thread is created.
- workqueue.insert
- probes queuing of work on a workqueue.
Arguments:
wq_thread
task_struct of the workqueue thread.work
work_struct* being executed.work_func
pointer to handler func.
- workqueue.execute
- probes execution of deferred work.
Arguments:
wq_thread
task_struct of the workqueue thread.work
work_struct* being executed.work_func
pointer to handler func.
- workqueue.destroy
- probes destruction of each worker thread of each cpu for a workqueue.
Arguments:
wq_thread
task_struct of the workqueue thread.
- irq_handler.entry
- Fires prior to execution of interrupt handler.
Arguments:
irq
irq numberaction
struct irqaction* for this interrupt numberhandler
interrupt handler functionflags
flags for this irq.flags_str
A formatted string of flags.dev_name
name of devicedev_id
cookie to identify devicenext_irqaction
pointer to next irqaction for shared interruptsdir
pointer to the /proc/irq/NN/name entrythread_fn
interrupt handler function for threaded interruptsthread
thread pointer for threaded interruptsthread_flags
flags related to thread
- irq_handler.exit
- Fires post execution of interrupt handler.
Arguments:
irq
irq numberaction
struct irqaction* for this interrupt numberret
return value from interrupt handler that just executed.handler
interrupt handler functionflags
flags for this irq.flags_str
A formatted string of flags.dev_name
name of devicedev_id
cookie to identify devicenext_irqaction
pointer to next irqaction for shared interruptsdir
pointer to the /proc/irq/NN/name entrythread_fn
interrupt handler function for threaded interruptsthread
thread pointer for threaded interruptsthread_flags
flags related to thread
- softirq.entry
- triggered just before executing handler for a pending softirq
Arguments:
h
struct softirq* for current pending softirq.vec
softirq_action vectoraction
pointer to softirq handler just about to execute.
- softirq.exit
- triggered just after executing handler for a pending softirq
Arguments:
h
struct softirq* for just executed softirq.vec
softirq_action vectoraction
pointer to softirq handler that just finished execution.
