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}]

27 # KMODLOAD Command to load a kernel module [/sbin/kldload]

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.

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 #

54 #
55 # install:
56 # install the kernel module; if the Makefile

60 # is executed.
