|
|
|
|
|
The

|
|
|
.Nm
|
|
|
|
|
utility loads a loadable kernel module into a running system.
|
|
|
|
|
The input file is an object file (.o file).
|
|

|
.Pp
|
|
|
|
|
The options to

.Pq Ar output_file
|
1995-10-28 17:06:05 +00:00
|
|
|
after loading. If the output file was not specified, this option causes the
|
|
|
|
|
temporary file to be kept rather than deleted.
|
1994-08-19 12:07:23 +00:00
|
|
|
.It Fl v
|
|
|
|
|
Print comments about the loading process.
|
|
|
|
|
.It Fl A Ar kernel
|
|
|
|
|
Specify the file that is passed to the linker
|
|
|
|
|
to resolve module references to external symbols.
|
|
|
|
|
The symbol file must be for the currently running
|
|
|
|
|
kernel or the module is likely to crash the system.
|
|
|
|
|
.It Fl e Ar entry
|
|
|
|
|
Specify the module entry point.
|
|
|
|
|
This is passed by
|
|
|
|
|
.Nm
|
|
|
|
|
to
|
|
|
|
|
.Xr ld 1
|
|
|
|
|
when the module is linked.
|
1995-10-28 13:06:11 +00:00
|
|
|
The default module entry point name is the module name with `_mod' appended.
|
1994-08-19 12:07:23 +00:00
|
|
|
.It Fl p Ar postinstall
|
|
|
|
|
Specify the name of a shell script or program 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.
|
1994-09-18 04:12:13 +00:00
|
|
|
For loadable drivers, the third argument is
|
|
|
|
|
the block or character major device number.
|
1994-08-19 12:07:23 +00:00
|
|
|
For a loadable system call, the third argument is the system
|
|
|
|
|
call number.
|
|
|
|
|
.It Fl o Ar output_file
|
|
|
|
|
Specify the name of the output file that is produced by
|
1995-10-28 17:06:05 +00:00
|
|
|
the linker. If this option is not specified, a file in the /tmp directory
|
|
|
|
|
is used with the name generated from the module name with a `.out' extension.

.Sh BUGS
|
1994-09-22 22:35:53 +00:00
|
|
|
The loadable device driver framework can
|
1994-09-18 04:12:13 +00:00
|
|
|
only reserve either a character or block device entry, not both.
