Introduction

This document describes sysconf UI command syntax and introduces the example use of the command for creating a device hierarchy that similate a hardware system.

sysconf UI command

Syntax

sysconf [ -p mod_path ] module_name [ instance_name [ args ... ] [ -d# ] ]

cfg

sysconf

where:

mod_path	pathname for .so files
module_name	a module name defined by MMI
instance_name	a unique instance name
args	optional arguments, usually name=value pairs.
-d#	set debug level to control the amount of debug output

The .so filename is contructed as follows: mod_path/module_name.so. The default value for mod_path is ".". The -p switch sets a new module path, and remains in effect until the next -p switch.

Examples

 
Example device hierarchy:

ssm   ->cpu0
      ->cpu1
      ->schizo30->pcia->fc0
                      ->isa
                ->pcib->bootbus_ctrl
      ->schizo31->pcia->ge0
                      ->ge1
                ->pcib


Example sysconf commands for above device hierarchy:

sysconf -p ../blaze-conf/modules/64opt
sysconf schizo    schizo30      aid=30 pciA=pci30A pciB=pci30B
sysconf pci_bus   pci30A        bridge=schizo30
sysconf fc        fc0           bus=pci30A dev=0 fun=0
sysconf isa       isa0          bus=pci30A dev=7 fun=0
sysconf pci_bus   pci30B        bridge=schizo30
sysconf bootbus   bootbus_ctrl  bus=pci30B dev=4 fun=0
sysconf schizo    schizo31      aid=31 pciA=pci31A pciB=pci31B
sysconf pci_bus   pci31A        bridge=schizo31
sysconf ge        ge0           bus=pci31A dev=0 fun=0
sysconf ge        ge1           bus=pci31A dev=1 fun=0
sysconf pci_bus   pci31B        bridge=schizo31
