3#
4# The include file <bsd.kmod.mk> handles building and installing loadable
5# kernel modules.
6#
7#
8# +++ variables +++
9#
10# CLEANFILES	Additional files to remove for the clean and cleandir targets.
11#
12# EXPORT_SYMS	A list of symbols that should be exported from the module,
13#		or the name of a file containing a list of symbols, or YES
14#		to export all symbols.  If not defined, no symbols are
15#		exported.
16#
17# KMOD		The name of the kernel module to build.
18#
19# KMODDIR	Base path for kernel modules (see kld(4)). [/boot/kernel]
20#
21# KMODOWN	Module file owner. [${BINOWN}]
22#
23# KMODGRP	Module file group. [${BINGRP}]
24#
25# KMODMODE	Module file mode. [${BINMODE}]
26#
27# KMODLOAD	Command to load a kernel module [/sbin/kldload]
28#
29# KMODUNLOAD	Command to unload a kernel module [/sbin/kldunload]
30#
31# KMODISLOADED	Command to check whether a kernel module is
32#		loaded [/sbin/kldstat -q -n]
33#
34# PROG		The name of the kernel module to build.
35#		If not supplied, ${KMOD}.ko is used.
36#
37# SRCS		List of source files.
38#
39# FIRMWS	List of firmware images in format filename:shortname:version
40#
41# FIRMWARE_LICENSE
42#		Set to the name of the license the user has to agree on in
43#		order to use this firmware. See /usr/share/doc/legal
44#
45# DESTDIR	The tree where the module gets installed. [not set]
46#
47# KERNBUILDDIR	Set to the location of the kernel build directory where
48#		the opt_*.h files, .o's and kernel winds up.
49#
50# BLOB_OBJS	Prebuilt binary blobs .o's from the src tree to be linked into
51#		the module. These are precious and not removed in make clean.
52#
53# +++ targets +++
54#
55# 	install:
56#               install the kernel module; if the Makefile
57#               does not itself define the target install, the targets
58#               beforeinstall and afterinstall may also be used to cause
59#               actions immediately before and after the install target
60#		is executed.
61#
62# 	load:
63#		Load a module.
64#
65# 	unload:
66#		Unload a module.
67#
68#	reload:
69#		Unload if loaded, then load.
