KEXTSTAT(8) BSD System Manager's Manual KEXTSTAT(8)NAMEkextstat — display status of dynamically loaded kernel extensions
SYNOPSISkextstat [-b kext_bundle_id] [-k] [-l]
DESCRIPTION
The kextstat utility displays the status of any kernel extensions cur‐
rently 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 refer‐
ences). 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 occu‐
pies. 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.
