4# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
5# drivers (KLD's).
6#
7#
8# +++ variables +++
9# CLEANFILES	Additional files to remove for the clean and cleandir targets.
10#
11# KMOD          The name of the kernel module to build.

24# KMODUNLOAD	Command to unload a kernel module [/sbin/kldunload]
25#
26# PROG          The name of the kernel module to build.
27#		If not supplied, ${KMOD}.o is used.
28#
29# SRCS          List of source files
30#
31# DESTKERNDIR	Change the tree where the kernel and the modules get

44# KERNBUILDDIR	Set to the location of the kernel build directory where
45#		the opt_*.h files, .o's and kernel wind up.
46#
47# +++ targets +++
48#
49# 	install:
50#               install the kernel module and its manual pages; if the Makefile
51#               does not itself define the target install, the targets
52#               beforeinstall and afterinstall may also be used to cause
53#               actions immediately before and after the install target
54#		is executed.
