is an experimental scheduler that provides a number of advanced scheduler
|
||||
features not present in
|
||||
.Xr sched_4bsd 4 ,
|
||||
the default system scheduler, nor
|
||||
.Xr sched_ule 4
|
||||
where it is forked off.
|
||||
These features address SMP and interactivity and include:
|
||||
.Pp
|
||||
.Bl -bullet -compact -offset indent
|
||||
.It
|
||||
Nice value of timesharing processes is respected.
|
||||
Allocation of
|
||||
time slice and interaction detection algorithm are based on
|
||||
nice value.
|
||||
.It
|
||||
Per-CPU scheduling queue and load balancing.
|
||||
.It
|
||||
O(1) scheduling.
|
||||
.It
|
||||
Some CPU affinity code in wakeup path.
|
||||
.It
|
||||
Some preliminary support for Hyper Threading Technology.
|
||||
.It
|
||||
Support for POSIX SCHED_FIFO and SCHED_RR.
|
||||
.El
|
||||
.Pp
|
||||
The following sysctls are relevant to the operation of
|
||||
.Nm :

|
||||
read-only.
|
||||
.It Va kern.sched.ipiwakeup.requested
|
||||
(SMP specific) Completed forwarding of wakeup to idle CPUs,
|
||||
read-only.
|
||||
.It Va kern.sched.ipiwakeup.usemask
|
||||
(SMP specific) Whether to use the mask of idle CPUs.
|
||||
.It Va kern.sched.ipiwakeup.useloop
|
||||
(SMP specific) Whether to use loop to find idle CPUs.
|
||||
.It Va kern.sched.ipiwakeup.onecpu
|
||||
(SMP specific) Whether to only signal one CPU when doing wakeup.
|
||||
.It Va kern.sched.ipiwakeup.htt
|
||||
(SMP specific) Whether to take Hyper-Threading into account.
