KLDSTAT(8) System Manager's Manual KLDSTAT(8) NAME kldstat -- display status of dynamic kernel linker SYNOPSIS kldstat [-h] [-q] [-v] [-d] [-i id] [-n filename] kldstat [-q] [-d] [-m modname] DESCRIPTION The kldstat utility displays the status of any files dynamically linked into the kernel. The following options are available: -d Show the module specific data (as int, unsigned int and unsigned long) -h Display the size field in a human-readable form, using unit suffixes instead of hex values. -i id Display the status of only the file with this ID. -m modname Display the status of only the module with this modname. -n filename Display the status of only the file with this filename. -q Quietly check if file is loaded or compiled into the ker- nel. -v Be more verbose. EXIT STATUS The kldstat utility exits 0 on success, and >0 if an error occurs. EXAMPLES Show files dynamically linked into the kernel. Note the kernel itself is shown in the list. Refs shows the number of modules referenced by each file: $ kldstat Id Refs Address Size Name 1 38 0xffffffff80200000 2448f20 kernel 2 3 0xffffffff82649000 b7bd8 linux.ko 3 5 0xffffffff82701000 9698 linux_common.ko 4 1 0xffffffff82b11000 1eae linsysfs.ko 5 1 0xffffffff82b13000 f2af8 nvidia-modeset.ko 6 1 0xffffffff82c06000 122b020 nvidia.ko 7 1 0xffffffff83e32000 2668 intpm.ko 8 1 0xffffffff83e35000 b50 smbus.ko 9 1 0xffffffff83e36000 18a0 uhid.ko 10 1 0xffffffff83e38000 2928 ums.ko 11 1 0xffffffff83e3b000 1aa0 wmt.ko 12 1 0xffffffff83e3d000 cd70 snd_uaudio.ko Show the verbose status of the linux file and show the size in a human readable fashion: $ kldstat -h -v -n linux Id Refs Address Size Name 2 3 0xffffffff82649000 735K linux.ko (/boot/kernel/linux.ko) Contains modules: Id Name 2 linuxelf Same as above using the id of the file: $ kldstat -h -i 2 -v Id Refs Address Size Name 2 3 0xffffffff82649000 735K linux.ko (/boot/kernel/linux.ko) Contains modules: Id Name 2 linuxelf Show the status of the linuxelf module obtained from the example above: $ kldstat -v -m linuxelf Id Refs Name 2 1 linuxelf Show the module specific data for the g_raid module: $ kldstat -d -m g_raid Id Refs Name data..(int, uint, ulong) 366 1 g_raid (0, 0, 0x0) Check if the module fakefile is linked. Returns 0 if it is, 1 other- wise: $ kldstat -q -n fakefile || echo file not linked file not linked SEE ALSO kldstat(2), kldload(8), kldunload(8) HISTORY The kldstat utility first appeared in FreeBSD 3.0, replacing the lkm interface.
