A question from my email bag - How do you find out all drivers loaded by FreeBSD kernel?
Simply use the kldstat command to display the status of any files dynamically linked into the kernel. The kldstat utility first appeared in FreeBSD 3.0, replacing the lkm interface.
kldstat Command Example
Use kldstat command as follows:
# kldstat
Sample outputs:
Id Refs Address Size Name 1 6 0xc0100000 52679c kernel 3 1 0xc063b000 4a6ac acpi.ko 8 1 0xc162e000 1f000 smbfs.ko 9 2 0xc1303000 3000 libiconv.ko 10 2 0xc1309000 3000 libmchain.ko
Where:
- ID : Module id which can be used to remove module
- Ref Address: Memory address
- Size : Size of module
- Name : Module name or file located in /boot/kernel directory
