11 # @ECLASS: linux-mod.eclass
12 # @MAINTAINER:
13 # kernel-misc@gentoo.org
14 # @BLURB: It provides the functionality required to install external modules against a kernel source tree.
15 # @DESCRIPTION:
16 # This eclass is used to interface with linux-info.eclass in such a way
17 # to provide the functionality and initial functions
18 # required to install external modules against a kernel source
19 # tree.
20
21 # A Couple of env vars are available to effect usage of this eclass
22 # These are as follows:
23
24 # @ECLASS-VARIABLE: KERNEL_DIR
25 # @DESCRIPTION:
26 # A string containing the directory of the target kernel sources. The default value is
27 # "/usr/src/linux"
28
29 # @ECLASS-VARIABLE: ECONF_PARAMS
30 # @DESCRIPTION:
31 # It's a string containing the parameters to pass to econf.
32 # If this is not set, then econf isn't run.
33
34 # @ECLASS-VARIABLE: BUILD_PARAMS
35 # @DESCRIPTION:
36 # It's a string with the parameters to pass to emake.
37
38 # @ECLASS-VARIABLE: BUILD_TARGETS
39 # @DESCRIPTION:
40 # It's a string with the build targets to pass to make. The default value is "clean modules"
41
42 # @ECLASS-VARIABLE: MODULE_NAMES
43 # @DESCRIPTION:
44 # It's a string containing the modules to be built automatically using the default
45 # src_compile/src_install. It will only make ${BUILD_TARGETS} once in any directory.
46
47 #
48 # The structure of each MODULE_NAMES entry is as follows:
49 #
50 # modulename(libdir:srcdir:objdir)
51 #
52 # where:
53 #
54 # modulename = name of the module file excluding the .ko
55 # libdir = place in system modules directory where module is installed:
56 # srcdir = place for ebuild to cd to before running make
57 # objdir = place the .ko and objects are located after make runs
58 #
59 # To get an idea of how these variables are used, here's a few lines
60 # of code from around line 540 in this eclass:
61 #
62 # einfo "Installing ${modulename} module"
63 # cd ${objdir} || die "${objdir} does not exist"
64 # insinto /lib/modules/${KV_FULL}/${libdir}
65 # doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
66 #
67 # For example:
68 # MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
69 #
70 # what this would do is
71 #
72 # cd "${S}"/pci
73 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
74 # cd "${S}"
75 # insinto /lib/modules/${KV_FULL}/pci
76 # doins module_pci.${KV_OBJ}
77 #
78 # cd "${S}"/usb
79 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
80 # cd "${S}"
81 # insinto /lib/modules/${KV_FULL}/usb
82 # doins module_usb.${KV_OBJ}
83
84 # There is also support for automated modprobe.d/modules.d(2.4) file generation.
85 # This can be explicitly enabled by setting any of the following variables.
86
87 # @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED
88 # @DESCRIPTION:
89 # This is used to disable the modprobe.d/modules.d file generation otherwise the file will be
90 # always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable
91 # the generation of the file and the installation of the documentation.
92
93 # @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
94 # @DESCRIPTION:
95 # This is a bash array containing a list of examples which should
96 # be used. If you want us to try and take a guess set this to "guess".
97 #
98 # For each array_component it's added an options line in the modprobe.d/modules.d file
99 #
100 # options array_component
101 #
102 # where array_component is "<modulename> options" (see modprobe.conf(5))
103
104 # @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
105 # @DESCRIPTION:
106 # This is a bash array containing a list of associated aliases.
107 #
108 # For each array_component it's added an alias line in the modprobe.d/modules.d file
109 #
110 # alias array_component
111 #
112 # where array_component is "wildcard <modulename>" (see modprobe.conf(5))
113
114 # @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
115 # @DESCRIPTION:
116 # This is a bash array containing a list of additional things to
117 # add to the bottom of the file. This can be absolutely anything.
118 # Each entry is a new line.
119
120 # @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
121 # @DESCRIPTION:
122 # This is a string list which contains the full path to any associated
123 # documents for <modulename>. These files are installed in the live tree.
124
125 # @ECLASS-VARIABLE: KV_OBJ
126 # @DESCRIPTION:
127 # It's a read-only variable. It contains the extension of the kernel modules.
128
129 # The order of these is important as both of linux-info and eutils contain
130 # set_arch_to_kernel and set_arch_to_portage functions and the ones in eutils
131 # are deprecated in favor of the ones in linux-info.
