5# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
6# drivers (KLD's).
7#
8#
9# +++ variables +++
10#
11# CLEANFILES	Additional files to remove for the clean and cleandir targets.
12#
13# KMOD          The name of the kernel module to build.
14#
15# KMODDIR	Base path for kernel modules (see kld(4)). [/modules]
16#
17# KMODOWN	KLD owner. [${BINOWN}]
18#
19# KMODGRP	KLD group. [${BINGRP}]
20#
21# KMODMODE	KLD mode. [${BINMODE}]
22#
23# KMODLOAD	Command to load a kernel module [/sbin/kldload]
24#
25# KMODUNLOAD	Command to unload a kernel module [/sbin/kldunload]
26#
27# NOMAN		KLD does not have a manual page if set.
28#
29# PROG          The name of the kernel module to build.
30#		If not supplied, ${KMOD}.o is used.
31#
32# SRCS          List of source files
33#
34# KMODDEPS	List of modules which this one is dependant on
35#
36# DESTDIR	Change the tree where the module gets installed. [not set]
37#
38# MFILES	Optionally a list of interfaces used by the module.
39#		This file contains a default list of interfaces.
40#
41# +++ targets +++
42#
43# 	install:
44#               install the kernel module and its manual pages; if the Makefile
45#               does not itself define the target install, the targets
46#               beforeinstall and afterinstall may also be used to cause
47#               actions immediately before and after the install target
48#		is executed.
49#
50# 	load:
51#		Load KLD.
52#
53# 	unload:
54#		Unload KLD.
