.Sh DESCRIPTION
|
|
.Nm Sicontrol
|
|
is used to configure and monitor the SI/XIO device driver.
|
|
.Pp
|
|
.Nm Sicontrol
|
|
operates on the specified
|
|
.Ar device
|
|
to indicate which port is to be used.
|
|
.Pp
|
|
The special
|
|
.Ar device
|
|
string `-' is used to indicate the global driver settings instead.
|
|
.Pp
|
|
A '/dev/' is included if necessary.
|
|
.Pp
|
|
The following commands are used for the global settings and should be
|
|
specified with the '-' device name.
|
|
.Bl -tag -width 4n
|
|
.It Cm int_throttle Op Cm value
|
|
Configure the `aggregate interrupt throttle value'.
|
|
The maximum number of host adapter interrupts per second is determined by:
|
|
.Pp
|
|
.Ar "controller CPU clock / (8 * int_throttle)"
|
|
.Pp
|
|
The default value at boot time is 25000. The host adapter cpu clock is
|
|
25Mhz. This gives a maximum interrupt rate of about 125 interrupts per
|
|
second.
|
|
.Pp
|
|
Lowering this value will increase the rate in which the host adapter can
|
|
interrupt the operating system for attention.
|
|
.\"
|
|
.It Cm rxint_throttle Op Cm value
|
|
Configure the receiver interrupt throttle value.
|
|
The default value of 4 at boot time allows an interrupt rate of
|
|
approximately 25.
|
|
.Pp
|
|
Lowering this value will increase the rate in which the host adapter can
|
|
interrupt the operating system to empty the receiver fifos.
|
|
.\"
|
|
.It Cm nport
|
|
Return the number of ports under the control of the device driver.
|
|
.El
|
|
.Pp
|
|
The following commands are used for the individual ports and should be
|
|
specified with a device name from
|
|
.Pa /dev :
|
|
.Bl -tag -width 4n
|
|
.It Cm mstate
|
|
Show the current incoming modem control signals.
|
|
.It Cm ccbstat
|
|
Show the current "ccb" structure for the specified port.
|
|
This is not of
|
|
much use outside of debugging the driver and determining why a port is
|
|
wedged.
|
|
.It Cm ttystat
|
|
Show the current "tty" structure that the kernel has for the specified port.
|
|
This is not much use outside of debugging the driver.
