NAME

modload − load a kernel module

SYNOPSIS

modload filename [ −d ] [ −v ] [ −sym ] [ −A vmunix_file ] [ −conf config_file ] [ −entry entry_point ]

[ −exec exec_file ] [ −o output_file ]

DESCRIPTION

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

OPTIONS

−d Debug.  Used to debug modload itself. 

−v Verbose.  Print comments on the loading process. 

−sym Preserve symbols for use by kadb(8S). 

−A vmunix_file
Specify the file that is passd 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. 

−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 recognized, blockmajor and charmajor.  See the Writing Device Drivers for information on these commands. 

−entry entry_point
Specify 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
Specify 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 (in decimal) and module type (in hexadecimal) as the first two arguments. Module types are listed in /usr/include/sun/vddrv.h.  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
Specify 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’.
