kextstat -- display status of loaded kernel extensions (kexts)

kextstat [-h] [-k] [-l] [-b identifier] …

displays the status of any kexts currently loaded in the kernel.

Index load index of the kext (used to track linkage references). Gaps in the list indicate kexts that have been unloaded.
Refs number of references to this kext by others. If nonzero, the kext cannot be unloaded.
Address address in kernel space where the kext has been loaded.
Size number of bytes of kernel memory that the kext occupies. If this is zero, the kext is a built-in part of the kernel that has a record as a kext for resolving dependencies among kexts.
Wired number of wired bytes of kernel memory that the kext occupies.
Name CFBundleIdentifier of the kext.
(Version) CFBundleVersion of the kext.
<Linked Against> index numbers of all other kexts that this kext has a reference to.

-b identifier
-bundle-id identifier
Display the status of only the kext with the given bundle identifier. This option trumps the -no-kernel option; if both are given and a kernel component is specified, its information is shown.
-h
-help
output a help message describing each option flag and exit with a success result, regardless of any other options on the command line.
usage: kextstat [-k] [-l] [-b bundle_id] ...
-no-kernel (-k): show only loadable kexts (omit kernel components).
-list-only (-l): print the list only, omitting the header.
-bundle-id (-b) : print info for kexts named by identifier.
-k
-no-kernel
Don't show information for built-in components of the kernel.
-l
-list-only
loaded kexts only and omit the header (useful for running output through text-analysis tools).
