-.Dt SCHED_CORE 4
-.Sh NAME
-.Nm sched_core
-.Nd CORE scheduler
-.Sh SYNOPSIS
-.Cd "options SCHED_CORE"
-.Sh DESCRIPTION
-The
-.Nm
-scheduler
-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 :
-.Bl -tag -width indent
-.It Va kern.sched.name
-This read-only sysctl reports the name of the active scheduler.
-.It Va kern.sched.ipiwakeup.enabled
-(SMP specific) Whether to allow forwarding of wakeup to idle CPUs.
-.It Va kern.sched.ipiwakeup.requested
-(SMP specific) Requests for forwarding of wakeup to idle CPUs,
-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.
-.El
-.Pp
-The
-.Nm
-scheduler
-is not enabled by default as it is experimental.
-.Sh SEE ALSO

-.Sh HISTORY
-The
-.Nm
-scheduler first appeared in
