KEXTSTAT(8)               BSD System Manager's Manual              KEXTSTAT(8)

NAME
     kextstat -- display status of dynamically loaded kernel extensions

SYNOPSIS
     kextstat [-b kext_bundle_id] [-k] [-l]

DESCRIPTION
     The kextstat utility displays the status of any kernel extensions currently loaded in the kernel.  The
     following information is shown for each loaded kernel extension:

     Index     The load index of the kernel extension (used to track references).  Gaps in the list indicate
               kernel extensions that have been unloaded.

     Refs      The number of references to this extension by others.  If nonzero, the extension cannot be
               unloaded.

     Address   The address in kernel space where the extension has been loaded.

     Size      The number of bytes of kernel memory that the extension occupies.  If this is zero, the
               extension is actually a built-in part of the kernel that has a record as an extension for
               resolving dependencies among extensions.

     Wired     The number of wired bytes of kernel memory that the extension occupies.

     Name      The CFBundleIdentifier of the kernel extension.

     (Version)
               The CFBundleVersion of the kernel extension.

     <Linked Against>
               The index numbers of all other kernel extensions that this extension has a reference to.

     The following options are available:

     -b kext_bundle_id
               Display the status of only the kernel extension with the given bundle identifier.  This
               option trumps the -k option; if both are given and a kernel component is specified, its
               information is shown.

     -k        Don't show information for built-in components of the kernel.

     -l        Print the list of loaded kexts only and omit the header (useful for running output through
               text-analysis tools).

DIAGNOSTICS
     The kextstat utility exits with a status of 0 on success and with a nonzero status if an error occurs.

     The kextstat command is based on the command kldstat written by Doug Rabson <dfr@FreeBSD.org>
