1 # From: @(#)bsd.prog.mk 5.26 (Berkeley) 6/25/91
4 # The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
10 # CLEANFILES Additional files to remove for the clean and cleandir targets.
12 # DISTRIBUTION Name of distribution. [bin]
14 # KMOD The name of the kernel module to build.
16 # KMODDIR Base path for kernel modules (see kld(4)). [/boot/kernel]
18 # KMODOWN KLD owner. [${BINOWN}]
20 # KMODGRP KLD group. [${BINGRP}]
22 # KMODMODE KLD mode. [${BINMODE}]
24 # LINKS The list of KLD links; should be full pathnames, the
25 # linked-to file coming first, followed by the linked
26 # file. The files are hard-linked. For example, to link
27 # /modules/master and /modules/meister, use:
29 # LINKS= /modules/master /modules/meister
31 # KMODLOAD Command to load a kernel module [/sbin/kldload]
33 # KMODUNLOAD Command to unload a kernel module [/sbin/kldunload]
35 # PROG The name of the kernel module to build.
36 # If not supplied, ${KMOD}.o is used.
38 # SRCS List of source files
40 # SUBDIR A list of subdirectories that should be built as well.
41 # Each of the targets will execute the same target in the
44 # SYMLINKS Same as LINKS, except it creates symlinks and the
45 # linked-to pathname may be relative.
47 # DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk)
49 # MFILES Optionally a list of interfaces used by the module.
50 # This file contains a default list of interfaces.
52 # EXPORT_SYMS A list of symbols that should be exported from the module,
53 # or the name of a file containing a list of symbols, or YES
54 # to export all symbols. If not defined, no symbols are
60 # This is a variant of install, which will
61 # put the stuff into the right "distribution".
64 # install the kernel module; if the Makefile
65 # does not itself define the target install, the targets
66 # beforeinstall and afterinstall may also be used to cause
67 # actions immediately before and after the install target
76 # bsd.obj.mk: clean, cleandir and obj
77 # bsd.dep.mk: cleandepend, depend and tags
