11 # @BLURB: It provides the functionality required to install external modules against a kernel source tree.
12 # @DESCRIPTION:
13 # This eclass is used to interface with linux-info.eclass in such a way
14 # to provide the functionality and initial functions
15 # required to install external modules against a kernel source
16 # tree.
17
18 # A Couple of env vars are available to effect usage of this eclass
19 # These are as follows:
20
21 # @ECLASS-VARIABLE: MODULES_OPTIONAL_USE
22 # @DESCRIPTION:
23 # A string containing the USE flag to use for making this eclass optional
24 # The recommended non-empty value is 'modules'
25
26 # @ECLASS-VARIABLE: KERNEL_DIR
27 # @DESCRIPTION:
28 # A string containing the directory of the target kernel sources. The default value is
29 # "/usr/src/linux"
30
31 # @ECLASS-VARIABLE: ECONF_PARAMS
32 # @DESCRIPTION:
33 # It's a string containing the parameters to pass to econf.
34 # If this is not set, then econf isn't run.
35
36 # @ECLASS-VARIABLE: BUILD_PARAMS
37 # @DESCRIPTION:
38 # It's a string with the parameters to pass to emake.
39
40 # @ECLASS-VARIABLE: BUILD_TARGETS
41 # @DESCRIPTION:
42 # It's a string with the build targets to pass to make. The default value is "clean module"
43
44 # @ECLASS-VARIABLE: MODULE_NAMES
45 # @DESCRIPTION:
46 # It's a string containing the modules to be built automatically using the default
47 # src_compile/src_install. It will only make ${BUILD_TARGETS} once in any directory.
48 #
49 # The structure of each MODULE_NAMES entry is as follows:
50 #
51 # modulename(libdir:srcdir:objdir)
52 #
53 # where:
54 #
55 # modulename = name of the module file excluding the .ko
56 # libdir = place in system modules directory where module is installed (by default it's misc)
57 # srcdir = place for ebuild to cd to before running make (by default it's ${S})
58 # objdir = place the .ko and objects are located after make runs (by default it's set to srcdir)
59 #
60 # To get an idea of how these variables are used, here's a few lines
61 # of code from around line 540 in this eclass:
62 #
63 # einfo "Installing ${modulename} module"
64 # cd ${objdir} || die "${objdir} does not exist"
65 # insinto /lib/modules/${KV_FULL}/${libdir}
66 # doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
67 #
68 # For example:
69 # MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
70 #
71 # what this would do is
72 #
73 # cd "${S}"/pci
74 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
75 # cd "${S}"
76 # insinto /lib/modules/${KV_FULL}/pci
77 # doins module_pci.${KV_OBJ}
78 #
79 # cd "${S}"/usb
80 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
81 # cd "${S}"
82 # insinto /lib/modules/${KV_FULL}/usb
83 # doins module_usb.${KV_OBJ}
84
85 # There is also support for automated modprobe.d file generation.
86 # This can be explicitly enabled by setting any of the following variables.
87
88 # @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED
89 # @DESCRIPTION:
90 # This is used to disable the modprobe.d file generation otherwise the file will be
91 # always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable
92 # the generation of the file and the installation of the documentation.
93
94 # @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
95 # @DESCRIPTION:
96 # This is a bash array containing a list of examples which should
97 # be used. If you want us to try and take a guess set this to "guess".
98 #
99 # For each array_component it's added an options line in the modprobe.d file
100 #
101 # options array_component
102 #
103 # where array_component is "<modulename> options" (see modprobe.conf(5))
104
105 # @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
106 # @DESCRIPTION:
107 # This is a bash array containing a list of associated aliases.
108 #
109 # For each array_component it's added an alias line in the modprobe.d file
110 #
111 # alias array_component
112 #
113 # where array_component is "wildcard <modulename>" (see modprobe.conf(5))
114
115 # @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
116 # @DESCRIPTION:
117 # This is a bash array containing a list of additional things to
118 # add to the bottom of the file. This can be absolutely anything.
119 # Each entry is a new line.
120
121 # @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
122 # @DESCRIPTION:
123 # This is a string list which contains the full path to any associated
124 # documents for <modulename>. These files are installed in the live tree.
125
126 # @ECLASS-VARIABLE: KV_OBJ
127 # @DESCRIPTION:
128 # It's a read-only variable. It contains the extension of the kernel modules.
