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 # 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
28
29 # MODULE_NAMES - Detailed Overview
30 #
31 # The structure of each MODULE_NAMES entry is as follows:
32 # modulename(libmodulesdir:modulesourcedir)
33 # for example:
34 # MODULE_NAMES="module_pci(pci:${S}/pci) module_usb(usb:${S}/usb)"
35 #
36 # what this would do is
37 # cd ${S}/pci
38 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
39 # insinto /lib/modules/${KV_FULL}/pci
40 # doins module_pci.${KV_OBJ}
41 #
42 # cd ${S}/usb
43 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
44 # insinto /lib/modules/${KV_FULL}/usb
45 # doins module_usb.${KV_OBJ}
46 #
47 # if the modulessourcedir isnt specified, it assumes ${S}
48 # if the libmodulesdir isnt specified, it assumes misc.
49 # if no seperator is defined ":" then it assumes the argument is modulesourcedir
