||||||
.Sh DEPRECATION NOTICE
|
|
||||||
The
|
|
||||||
.Nm
|
|
||||||
utility is not present in
|
|
||||||
.Fx 12.0
|
|
||||||
and later.
|
|
||||||
The
|
|
||||||
.Xr kgdb 1
|
|
||||||
debugger handles kernel module state internally.
|
|
||||||
.Sh DESCRIPTION
|
|
||||||
By default,
|
|
||||||
.Nm
|
|
||||||
reads
|
|
||||||
.Xr kldstat 8
|
|
||||||
output from standard input and writes to the
|
|
||||||
.Pa .asf
|
|
||||||
file a list of
|
|
||||||
.Xr gdb 1
|
|
||||||
commands to add symbol files from KLDs in subdirectories of the subdirectory
|
|
||||||
.Pa modules
|
|
||||||
of the current directory, which is intended to be a kernel build directory.
|
|
||||||
This allows
|
|
||||||
.Xr gdb 1
|
|
||||||
to load the symbols into the debugging environment.
|
|
||||||
.Pp
|
|
||||||
An optional
|
|
||||||
.Ar modules-path
|
|
||||||
argument can specify a semicolon-separated list of directory pathnames
|
|
||||||
similar to the
|
|
||||||
.Va kern.module_path
|
|
||||||
sysctl.
|
|
||||||
Each directory in the list will be searched in turn for modules.
|
|
||||||
The default list consists of just one element,
|
|
||||||
.Pa modules ,
|
|
||||||
which is suitable if the current directory is a kernel build directory.
|
|
||||||
.Pp
|
|
||||||
If
|
|
||||||
.Ar outfile
|
|
||||||
is specified,
|
|
||||||
.Nm
|
|
||||||
writes to it instead of
|
|
||||||
.Pa .asf .
|
|
||||||
If
|
|
||||||
.Ar outfile
|
|
||||||
is a single dash
|
|
||||||
.Pq Sq Fl ,
|
|
||||||
standard output is used.
|
|
||||||
.Sh OPTIONS
|
|
||||||
The following options modify the function of
|
|
||||||
.Nm :
|
|
||||||
.Bl -tag -width indent
|
|
||||||
.It Fl a
|
|
||||||
When writing to an explicit
|
|
||||||
.Ar outfile ,
|
|
||||||
append to the file rather than overwriting it.
|
|
||||||
.It Fl f
|
|
||||||
Instead of trying to simplistically guess the path for each module, perform
|
|
||||||
a traversal in the same way that
|
|
||||||
.Xr find 1
|
|
||||||
does to locate an exact path for each module, no matter where in
|
|
||||||
.Ar modules-path
|
|
||||||
it is located.
|
|
||||||
.It Fl K
|
|
||||||
Instead of reading from standard input, use the conventional
|
|
||||||
system interface to get the list of modules currently loaded.
|
|
||||||
.It Fl k
|
|
||||||
Instead of reading from standard input, start a
|
|
||||||
.Xr kldstat 8
|
|
||||||
and read the information from it.
|
|
||||||
.It Fl M
|
|
||||||
Specify the core file for
|
|
||||||
.Xr kvm 3 .
|
|
||||||
Implies
|
|
||||||
.Fl V .
|
|
||||||
.It Fl N
|
|
||||||
Specify the system file for
|
|
||||||
.Xr kvm 3 .
|
|
||||||
Implies
|
|
||||||
.Fl V .
|
|
||||||
.It Fl o
|
|
||||||
Specify the file for
|
|
||||||
.Nm
|
|
||||||
to write or append its output to.
|
|
||||||
If
|
|
||||||
.Ar outfile
|
|
||||||
is a single dash
|
|
||||||
.Pq Sq Fl ,
|
|
||||||
standard output is used.
|
|
||||||
.It Fl s
|
|
||||||
Do not prepend a (guessed) subdirectory of the module path.
|
|
||||||
.It Fl V
|
|
||||||
Instead of reading from standard input, use the
|
|
||||||
.Xr kvm 3
|
|
||||||
interface to get the list of modules.
|
|
||||||
This interface allows for inspecting system crash dumps,
|
|
||||||
as well as the live system.
|
|
||||||
The
|
|
||||||
.Fl M
|
|
||||||
and
|
|
||||||
.Fl N
|
|
||||||
options will be of use if inspecting a crash dump.
|
|
||||||
Elevated privileges, e.g., those of a superuser,
|
|
||||||
may be needed to use this option.
|
|
||||||
.It Fl X
|
|
||||||
Add
|
|
||||||
.Ar suffix
|
|
||||||
to the list of suffixes
|
|
||||||
.Nm
|
|
||||||
tries to append to KLD file names.
|
|
||||||
The default list consists of
|
|
||||||
.Pa .debug ,
|
|
||||||
.Pa .symbols ,
|
|
||||||
and the null suffix.
|
|
||||||
The null suffix always stays at the list tail, after the suffix added.
|
|
||||||
Should it be needed in the middle of the list,
|
|
||||||
a blank suffix can be specified to
|
|
||||||
.Fl X
|
|
||||||
instead.
|
|
||||||
.It Fl x
|
|
||||||
Clear the list of suffixes
|
|
||||||
.Nm
|
|
||||||
tries to append to KLD file names.
|
|
||||||
Only the null suffix is left in the list.
|
|
||||||
.El
|
|
||||||
.Sh EXAMPLES
|
|
||||||
To add symbol files from the system search path specified by the
|
|
||||||
.Va kern.module_path
|
|
||||||
sysctl, the following command can be used:
|
|
||||||
.Pp
|
|
||||||
.Dl asf -s `sysctl -n kern.module_path`

|
||||||
.Sh BUGS
|
|
||||||
Module paths are guessed in a rather naive way by default.
|
|
||||||
It is likely to lag behind the changes to the build tree layout.
|
|
||||||
Using
|
|
||||||
.Fl f
|
|
||||||
is recommended.
