|

.Sh DESCRIPTION
|
||||
These functions raise and lower the interrupt priority level
|
||||
on i386.
|
||||
They are used by machine-dependent kernel code to implement
|
||||
the machine-independent
|
||||
.Xr spl 9
|
||||
interface.
|
||||
.Pp
|
||||
In a multi-CPU system, these functions change the interrupt
|
||||
priority level on the local CPU only.
|
||||
In general, device drivers should not make use of these functions.
|
||||
.Pp
|
||||
The
|
||||
.Fn spllower
|
||||
function sets the system priority level to the one encoded in
|
||||
.Fa s ,
|
||||
if
|
||||
.Fa s
|
||||
is lower than the current level.
|
||||
Otherwise, it does not change the level.
|
||||
Use
|
||||
.Fn splx
|
||||
instead
|
||||
of
|
||||
.Fn spllower ,
|
||||
except in extraordinary circumstances.
|
||||
.Pp
|
||||
The
|
||||
.Fn splraise
|
||||
function sets the system priority level to the one encoded in
|
||||
.Fa s ,
|
||||
if
|
||||
.Fa s
|
||||
is greater than the current level, and returns the previous level.
|
||||
Otherwise, it does not change the level, and it returns the current level.
|
||||
Except in extraordinary circumstances,
|
||||
do not use
|
||||
.Fn splraise .
|
||||
Use one of the priority-raising functions defined in
|
||||
.Xr spl 9 ,
|
||||
instead.
