5# This eclass provides functions for compiling external kernel modules 5# @ECLASS: linux-mod.eclass
6# from source. 6# @MAINTAINER:

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.
7 17
8inherit linux-info 18# A Couple of env vars are available to effect usage of this eclass
9ECLASS=linux-mod 19# These are as follows:
10INHERITED="$INHERITED $ECLASS"
11EXPORT_FUNCTIONS pkg_setup pkg_postinst src_compile
12 20
21# @ECLASS-VARIABLE: KERNEL_DIR
22# @DESCRIPTION:
23# A string containing the directory of the target kernel sources. The default value is
24# "/usr/src/linux"
25
26# @ECLASS-VARIABLE: ECONF_PARAMS
27# @DESCRIPTION:
28# It's a string containing the parameters to pass to econf.
29# If this is not set, then econf isn't run.
30
31# @ECLASS-VARIABLE: BUILD_PARAMS
32# @DESCRIPTION:
33# It's a string with the parameters to pass to emake.
34
35# @ECLASS-VARIABLE: BUILD_TARGETS
36# @DESCRIPTION:
37# It's a string with the build targets to pass to make. The default value is "clean module"
38
39# @ECLASS-VARIABLE: MODULE_NAMES
40# @DESCRIPTION:
41# It's a string containing the modules to be built automatically using the default
42# src_compile/src_install. It will only make ${BUILD_TARGETS} once in any directory.
43#
44# The structure of each MODULE_NAMES entry is as follows:
45#
46# modulename(libdir:srcdir:objdir)
47#
48# where:
49#
50# modulename = name of the module file excluding the .ko
51# libdir = place in system modules directory where module is installed (by default it's misc)
52# srcdir = place for ebuild to cd to before running make (by default it's ${S})
53# objdir = place the .ko and objects are located after make runs (by default it's set to srcdir)
54#
55# To get an idea of how these variables are used, here's a few lines
56# of code from around line 540 in this eclass:
57#
58# einfo "Installing ${modulename} module"
59# cd ${objdir} || die "${objdir} does not exist"
60# insinto /lib/modules/${KV_FULL}/${libdir}
61# doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
62#
63# For example:
64# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
65#
66# what this would do is
67#
68# cd "${S}"/pci
69# make ${BUILD_PARAMS} ${BUILD_TARGETS}
70# cd "${S}"
71# insinto /lib/modules/${KV_FULL}/pci
72# doins module_pci.${KV_OBJ}
73#
74# cd "${S}"/usb
75# make ${BUILD_PARAMS} ${BUILD_TARGETS}
76# cd "${S}"
77# insinto /lib/modules/${KV_FULL}/usb
78# doins module_usb.${KV_OBJ}
79
80# There is also support for automated modprobe.d/modules.d(2.4) file generation.
81# This can be explicitly enabled by setting any of the following variables.
82
83# @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED
84# @DESCRIPTION:
85# This is used to disable the modprobe.d/modules.d file generation otherwise the file will be
86# always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable
87# the generation of the file and the installation of the documentation.
88
89# @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
90# @DESCRIPTION:
91# This is a bash array containing a list of examples which should
92# be used. If you want us to try and take a guess set this to "guess".
93#
94# For each array_component it's added an options line in the modprobe.d/modules.d file
95#
96# options array_component
97#
98# where array_component is "<modulename> options" (see modprobe.conf(5))
99
100# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
101# @DESCRIPTION:
102# This is a bash array containing a list of associated aliases.
103#
104# For each array_component it's added an alias line in the modprobe.d/modules.d file
105#
106# alias array_component
107#
108# where array_component is "wildcard <modulename>" (see modprobe.conf(5))
109
110# @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
111# @DESCRIPTION:
112# This is a bash array containing a list of additional things to
113# add to the bottom of the file. This can be absolutely anything.
114# Each entry is a new line.
115
116# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
117# @DESCRIPTION:
118# This is a string list which contains the full path to any associated
119# documents for <modulename>. These files are installed in the live tree.
120
121# @ECLASS-VARIABLE: KV_OBJ
122# @DESCRIPTION:
123# It's a read-only variable. It contains the extension of the kernel modules.
