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
23 # isn't run.
24 # BUILD_PARAMS <string> The parameters to pass to emake.
25 # BUILD_TARGETS <string> clean modules The build targets to pass to
26 # make.
27 # MODULE_NAMES <string> This is the modules which are
28 # to be built automatically using
29 # the default pkg_compile/install.
30 # They are explained properly
31 # below. It will only make
32 # BUILD_TARGETS once in any
33 # directory.
34
35 # MODULE_NAMES - Detailed Overview
36 #
37 # The structure of each MODULE_NAMES entry is as follows:
38 # modulename(libdir:srcdir:objdir)
39 # for example:
40 # MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
41 #
42 # what this would do is
43 # cd ${S}/pci
44 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
45 # cd ${S}
46 # insinto /lib/modules/${KV_FULL}/pci
47 # doins module_pci.${KV_OBJ}
48 #
49 # cd ${S}/usb
50 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
51 # cd ${S}
52 # insinto /lib/modules/${KV_FULL}/usb
53 # doins module_usb.${KV_OBJ}
54 #
55 # if the srcdir isnt specified, it assumes ${S}
56 # if the libdir isnt specified, it assumes misc.
57 # if the objdir isnt specified, it assumes srcdir
58
59 # There is also support for automatyed modules.d file generation.
60 # This can be explicitly enabled by setting any of the following variables.
61 #
62 #
63 # MODULESD_${modulename}_ENABLED This enables the modules.d file
64 # generation even if we dont
65 # specify any additional info.
66 # MODULESD_${modulename}_EXAMPLES This is a bash array containing
67 # a list of examples which should
68 # be used. If you want us to try and
69 # take a guess. Set this to "guess"
70 # MODULESD_${modulename}_ALIASES This is a bash array containing
71 # a list of associated aliases.
72 # MODULESD_${modulename}_ADDITIONS This is a bash array containing
73 # A list of additional things to
74 # add to the bottom of the file.
75 # This can be absolutely anything.
76 # Each entry is a new line.
77 # MODULES_${modulename}_DOCS This is a string list which contains
78 # the full path to any associated
79 # documents for $modulename
