NAME

modload − load a Sun386i module

SYNOPSIS

modload filename [ −conf config_file ] [ −entry entry_point ] [ −exec exec_file ] [ −o output_file ]

[ −nolink ] [ −A vmunix_file ]

AVAILABILITY

Sun386i systems only. 

DESCRIPTION

modload loads a loadable module into a running system.  The input file filename is an object file (.o file). 

OPTIONS

−conf config_file
Use this configuration file to configure the loadable driver being loaded. The commands in this file are the same as those that the config(8) program recognizes.  There are two additional commands, blockmajor and charmajor, shown in the configuration file example below. 

−entry entry_point
This is the module entry point.  This is passed by modload to ld(1) when the module is linked.  The default module entry point name is ‘xxxinit’. 

−exec exec_file
This is the name of a shell script or executable image file that will be executed if the module is successfully loaded. It is always passed the module id and module type as the first two arguments.  For loadable drivers, the third and fourth arguments are the block major and character major numbers respectively. For a loadable system call, the third argument is the system call number.

−o output_file
This is the name of the output file that is produced by the linker. If this option is omitted, then the output file name is filename> without the ‘.o’. 

−nolink
This option can be used if modload has already been issued once and the output file already exists.  One must take care that neither the kernel nor the module have changed. 

−A vmunix_file
This is the file that is passed to the linker to resolve module references to kernel symbols.  The default is /vmunix.  The symbol file must be for the currently running kernel or the module is likely to crash the system.
