NAME
sicontrol
- Specialix SI/XIO driver configuration and debugging
SYNOPSIS
device
command [param ...
]
DESCRIPTION
The
utility is used to configure and monitor the SI/XIO device driver.
The
utility operates on the specified
device
to indicate which port is to be used.
The special
device
string `-' is used to indicate the global driver settings instead.
A
/dev/
is included if necessary.
The following commands are used for the global settings and should be
specified with the '-' device name:
- int_throttle [value
]
-
Configure the `aggregate interrupt throttle value'.
The maximum number of host adapter interrupts per second is determined by:
controller CPU clock / (8 * int_throttle)
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.
Lowering this value will increase the rate in which the host adapter can
interrupt the operating system for attention.
- rxint_throttle [value
]
-
Configure the receiver interrupt throttle value.
The default value of 4 at boot time allows an interrupt rate of
approximately 25.
Lowering this value will increase the rate in which the host adapter can
interrupt the operating system to empty the receiver fifos.
- nport
-
Return the number of ports under the control of the device driver.
The following commands are used for the individual ports and should be
specified with a device name from
/dev
- mstate
-
Show the current incoming modem control signals.
- 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.
- ttystat
-
Show the current "tty" structure that the kernel has for the specified port.
This is not much use outside of debugging the driver.
