SCHED_ULE(4)						   BSD Kernel Interfaces Manual 					      SCHED_ULE(4)

NAME

     sched_ule -- ULE scheduler

SYNOPSIS

     options SCHED_ULE

DESCRIPTION

     The sched_ule scheduler provides a number of advanced scheduler features not present in sched_4bsd(4), the traditional system scheduler.
     These features address SMP and interactivity and include:

	   o   Thread CPU affinity.
	   o   CPU topology awareness, including for hyper-threading.
	   o   Per-CPU run queues.
	   o   Interactivity heuristics that detect interactive applications and schedules them preferentially under high load.

     The following sysctls are relevant to the operation of sched_ule:

     kern.sched.name
	     This read-only sysctl reports the name of the active scheduler.

SEE ALSO

     sched_4bsd(4), sysctl(8)

HISTORY

     The sched_ule scheduler first appeared in FreeBSD 5.1.

DESCRIPTION

       scheduler.cpu_off
	      Process is about to stop running on a cpu

	       See probe::scheduler.cpu_off(3stap)
	       for details.

       scheduler.cpu_on
	      Process is beginning execution on a cpu

	       See probe::scheduler.cpu_on(3stap)
	       for details.

       scheduler.tick
	      Schedulers internal tick, a processes timeslice accounting is updated

	       See probe::scheduler.tick(3stap)
	       for details.

       scheduler.balance
	      A cpu attempting to find more work.

	       See probe::scheduler.balance(3stap)
	       for details.

       scheduler.ctxswitch
	      A context switch is occuring.

	       See probe::scheduler.ctxswitch(3stap)
	       for details.

       scheduler.kthread_stop
	      A thread created by kthread_create is being stopped

	       See probe::scheduler.kthread_stop(3stap)
	       for details.

       scheduler.kthread_stop.return
	      A kthread is stopped and gets the return value

	       See probe::scheduler.kthread_stop.return(3stap)
	       for details.

       scheduler.wait_task
	      Waiting on a task to unschedule (become inactive)

	       See probe::scheduler.wait_task(3stap)
	       for details.

       scheduler.wakeup
	      Task is woken up

	       See probe::scheduler.wakeup(3stap)
	       for details.

       scheduler.wakeup_new
	      Newly created task is woken up for the first time

	       See probe::scheduler.wakeup_new(3stap)
	       for details.

       scheduler.migrate
	      Task migrating across cpus

	       See probe::scheduler.migrate(3stap)
	       for details.

       scheduler.process_free
	      Scheduler freeing a data structure for a process

	       See probe::scheduler.process_free(3stap)
	       for details.

       scheduler.process_exit
	      Process exiting

	       See probe::scheduler.process_exit(3stap)
	       for details.

       scheduler.process_wait
	      Scheduler starting to wait on a process

	       See probe::scheduler.process_wait(3stap)
	       for details.

       scheduler.process_fork
	      Process forked

	       See probe::scheduler.process_fork(3stap)
	       for details.

       scheduler.signal_send
	      Sending a signal

	       See probe::scheduler.signal_send(3stap)
	       for details.
