5 # Description: This eclass is used to interface with linux-info in such a way
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 # ECONF_PARAMS <string> The parameters to pass to econf.
22 # If this is not set, then econf isn't
23 # run.
24 # BUILD_PARAMS <string> The parameters to pass to emake.
25 # BUILD_TARGETS <string> clean modules The build targets to pass to make.
26 # MODULE_NAMES <string> This is the modules which are
27 # to be built automatically using the
28 # default pkg_compile/install. They
29 # are explained properly below.
30 # It will only make BUILD_TARGETS once
31 # in any directory.
32 # NO_MODULESD <string> Set this to something to prevent
33 # modulesd file generation
34

36 # MODULE_NAMES - Detailed Overview
37 #
38 # The structure of each MODULE_NAMES entry is as follows:
39 # modulename(libmodulesdir:modulesourcedir)
40 # for example:
41 # MODULE_NAMES="module_pci(pci:${S}/pci) module_usb(usb:${S}/usb)"
42 #
43 # what this would do is
44 # cd ${S}/pci
45 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
46 # insinto /lib/modules/${KV_FULL}/pci
47 # doins module_pci.${KV_OBJ}
48 #
49 # cd ${S}/usb
50 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
51 # insinto /lib/modules/${KV_FULL}/usb
52 # doins module_usb.${KV_OBJ}
53 #
54 # if the modulessourcedir isnt specified, it assumes ${S}
55 # if the libmodulesdir isnt specified, it assumes misc.
56 # if no seperator is defined ":" then it assumes the argument is modulesourcedir
