6     # to provide the functionality required and initial functions
7     # required to install external modules against a kernel source
8     # tree.

15     # A Couple of env vars are available to effect usage of this eclass
16     # These are as follows:
17     #
18     # Env Var Option Default Description
19     # KERNEL_DIR <string> /usr/src/linux The directory containing kernel
20     # the target kernel sources.
21     # BUILD_PARAMS <string> The parameters to pass to make.
22     # BUILD_TARGETS <string> clean modules The build targets to pass to make.
23     # MODULE_NAMES <string> This is the modules which are
24     # to be built automatically using the
25     # default pkg_compile/install. They
26     # are explained properly below.
27 johnm 1.16 # It will only make BUILD_TARGETS once
28     # in any directory.
29 johnm 1.12 # NO_MODULESD <string> Set this to something to prevent
30     # modulesd file generation
31 johnm 1.10
32    
33     # MODULE_NAMES - Detailed Overview
34     #
35     # The structure of each MODULE_NAMES entry is as follows:
36     # modulename(libmodulesdir:modulesourcedir)
37     # for example:
38     # MODULE_NAMES="module_pci(pci:${S}/pci) module_usb(usb:${S}/usb)"
39     #
40     # what this would do is
41     # cd ${S}/pci
42     # make ${BUILD_PARAMS} ${BUILD_TARGETS}
43     # insinto /lib/modules/${KV_FULL}/pci
44     # doins module_pci.${KV_OBJ}
45     #
46     # cd ${S}/usb
47     # make ${BUILD_PARAMS} ${BUILD_TARGETS}
48     # insinto /lib/modules/${KV_FULL}/usb
49     # doins module_usb.${KV_OBJ}
50     #
51     # if the modulessourcedir isnt specified, it assumes ${S}
52     # if the libmodulesdir isnt specified, it assumes misc.
53     # if no seperator is defined ":" then it assumes the argument is modulesourcedir
