This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

.Sh DESCRIPTION
|
|
The
|
|
.Nm ncrcontrol
|
|
command symbolically displays the contents of the ncr810/ncr825
|
|
pci/scsi driver control structure.
|
|
There are a number of output formats,
|
|
depending on the options for the information presented.
|
|
It may be used to set some values, too.
|
|
|
|
.\"--------------------------------------------------------
|
|
.\" ncrcontrol [-Mcore] [-Nsystem] [-u unit] [-v] [-v] -i
|
|
.\"--------------------------------------------------------
|
|
The first form of the command displays an overview of the
|
|
connected targets. The
|
|
.Fl v
|
|
requests a verbose output.
|
|
|
|
.\"--------------------------------------------------------
|
|
.\" ncrcontrol [-N system] [-u unit] [-p wait]
|
|
.\"--------------------------------------------------------
|
|
Using the second form, with a
|
|
.Ar wait
|
|
interval specified,
|
|
.Nm ncrcontrol
|
|
will continuously display the information regarding data
|
|
traffic on the selected scsi bus.
|
|
|
|
.\"------------------------------------------------------------
|
|
.\" ncrcontrol [-Nsystem] [-u unit] [-t target] -s name=value
|
|
.\"------------------------------------------------------------
|
|
The third form sets a configuration value for one or all
|
|
targets of a selected scsi bus.
|
|
It normally is not needed, if the device driver options are
|
|
correctly set in kernel configuration.
|
|
|
|
.\"------------------------------------------------------------
|
|
.\" ncrcontrol [-M core] [-N system] [-u unit] [-t target] -w -d pattern
|
|
.\"------------------------------------------------------------
|
|
The forth form presents the content of the drivers control
|
|
structure. By the
|
|
.Ar pattern
|
|
certain parts of the output can be enabled/disabled.
|
|
It's only used to debug the driver.
|
|
|
|
.\"------------------------------------------------------------
|
|
.\" ncrcontrol [-N system] [-u unit] -w -k torture
|
|
.\"------------------------------------------------------------
|
|
With the last form certain driver problems can be forced.
|
|
THIS MAY CRASH YOUR SYSTEM.
|
|
It's only used to debug the driver.
|
|
|
|

Show the content of the drivers control structure.
|
|
The
|
|
.Ar pattern
|
|
selects the fields, which are displayed. With
|
|
.Fl d?
|
|
you can get a list of valid flags.
|
|
|
|
.\"------------------------------------------------------------
|
|
.\" -i
|
|
.\"------------------------------------------------------------
|
|
.It Fl i
|
|
Show the configuration state of the connected targets.
|
|
With the
|
|
.Fl v
|
|
option you can request a more verbose information.
|
|
|
|
.\"------------------------------------------------------------
|
|
.\" -k torture
|
|
.\"------------------------------------------------------------
|
|
.It Fl k
|
|
Force certain driver problems to check the error recovery
|
|
functions. This option should only be used by the developers.
|
|
With
|
|
.Fl k?
|
|
you can get a list of possible tortures.
|
|
This option requires the
|
|
.Fl w
|
|
option to be set.
|
|
|
|
.\"------------------------------------------------------------
|
|
.\" -M core
|

.\"------------------------------------------------------------
|
|
When
|
|
.Nm ncrcontrol
|
|
is invoked with a
|
|
.Ar wait
|
|
interval argument, it displays a running count of statistics related to
|
|
the transfers on the selected scsi bus.
|
|
|
|
This display consists of the number of transfers and number of transferred
|
|
bytes for the controller and for each connected target.

.Sh HISTORY
|
|
The
|
|
.Nm ncrcontrol
|
|
command was hacked for
|
|
.Bx 386
|
|
and ported to version 1.1 of
|
|
.Bx Free
|
|
by Wolfgang Stanglmeier <wolf@dentaro.GUN.de>.
|
|
It was ported to
|
|
.Bx Net
|
|
by Charles M. Hannum <mycroft@gnu.ai.mit.edu>
|
|
and to version 2.0 of
|
|
.Bx Free
|
|
by Stefan Esser <se@zpr.Uni-Koeln.DE>.

|
|
.Sh BUGS
|
|
The
|
|
.Nm ncrcontrol
|
|
was hacked as a debugging tool for the ncr810 driver.
|
|
It should be deleted sometimes.
|
|
There should be a general tool to change device driver options
|
|
on the fly.
|
|
The statistical data should be gathered by the generic scsi driver.
