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 # The structure of each MODULE_NAMES entry is as follows:
48 #
49 # modulename(libdir:srcdir:objdir)
50 #
51 # where:
52 #
53 # modulename = name of the module file excluding the .ko
54 # libdir = place in system modules directory where module is installed (by default it's misc)
55 # srcdir = place for ebuild to cd to before running make (by default it's ${S})
56 # objdir = place the .ko and objects are located after make runs (by default it's set to srcdir)
57 #
58 # To get an idea of how these variables are used, here's a few lines
59 # of code from around line 540 in this eclass:
60 #
61 # einfo "Installing ${modulename} module"
62 # cd ${objdir} || die "${objdir} does not exist"
63 # insinto /lib/modules/${KV_FULL}/${libdir}
64 # doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
65 #
66 # For example:
67 # MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
68 #
69 # what this would do is
70 #
71 # cd "${S}"/pci
72 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
73 # cd "${S}"
74 # insinto /lib/modules/${KV_FULL}/pci
75 # doins module_pci.${KV_OBJ}
76 #
77 # cd "${S}"/usb
78 # make ${BUILD_PARAMS} ${BUILD_TARGETS}
79 # cd "${S}"
80 # insinto /lib/modules/${KV_FULL}/usb
81 # doins module_usb.${KV_OBJ}
82
83 # There is also support for automated modprobe.d/modules.d(2.4) file generation.
84 # This can be explicitly enabled by setting any of the following variables.
85
86 # @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED
87 # @DESCRIPTION:
88 # This is used to disable the modprobe.d/modules.d file generation otherwise the file will be
89 # always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable
90 # the generation of the file and the installation of the documentation.
91
92 # @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
93 # @DESCRIPTION:
94 # This is a bash array containing a list of examples which should
95 # be used. If you want us to try and take a guess set this to "guess".
96 #
97 # For each array_component it's added an options line in the modprobe.d/modules.d file
98 #
99 # options array_component
100 #
101 # where array_component is "<modulename> options" (see modprobe.conf(5))
102
103 # @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
104 # @DESCRIPTION:
105 # This is a bash array containing a list of associated aliases.
106 #
107 # For each array_component it's added an alias line in the modprobe.d/modules.d file
108 #
109 # alias array_component
110 #
111 # where array_component is "wildcard <modulename>" (see modprobe.conf(5))
112
113 # @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
114 # @DESCRIPTION:
115 # This is a bash array containing a list of additional things to
116 # add to the bottom of the file. This can be absolutely anything.
117 # Each entry is a new line.
118
119 # @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
120 # @DESCRIPTION:
121 # This is a string list which contains the full path to any associated
122 # documents for <modulename>. These files are installed in the live tree.
123
124 # @ECLASS-VARIABLE: KV_OBJ
125 # @DESCRIPTION:
126 # It's a read-only variable. It contains the extension of the kernel modules.
127
128 # The order of these is important as both of linux-info and eutils contain
129 # set_arch_to_kernel and set_arch_to_portage functions and the ones in eutils
130 # are deprecated in favor of the ones in linux-info.
