30# They are explained properly

35# MODULE_NAMES - Detailed Overview 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 modules"
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.
36# 43#
37# The structure of each MODULE_NAMES entry is as follows: 44# The structure of each MODULE_NAMES entry is as follows:
45#
38# modulename(libdir:srcdir:objdir) 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#
39# for example: 63# For example:
40# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})" 64# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
41# 65#
42# what this would do is 66# what this would do is
67#
43# cd ${S}/pci 68# cd "${S}"/pci
44# make ${BUILD_PARAMS} ${BUILD_TARGETS} 69# make ${BUILD_PARAMS} ${BUILD_TARGETS}
45# cd ${S} 70# cd "${S}"
46# insinto /lib/modules/${KV_FULL}/pci 71# insinto /lib/modules/${KV_FULL}/pci
47# doins module_pci.${KV_OBJ} 72# doins module_pci.${KV_OBJ}
48# 73#
49# cd ${S}/usb 74# cd "${S}"/usb
50# make ${BUILD_PARAMS} ${BUILD_TARGETS} 75# make ${BUILD_PARAMS} ${BUILD_TARGETS}
51# cd ${S} 76# cd "${S}"
52# insinto /lib/modules/${KV_FULL}/usb 77# insinto /lib/modules/${KV_FULL}/usb
53# doins module_usb.${KV_OBJ} 78# doins module_usb.${KV_OBJ}

55# if the srcdir isnt specified, it assumes ${S}

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".
61# 93#
94# For each array_component it's added an options line in the modprobe.d/modules.d file
62# 95#
63# MODULESD_${modulename}_ENABLED This enables the modules.d file 96# options array_component
64# generation even if we dont 97#
65# specify any additional info. 98# where array_component is "<modulename> options" (see modprobe.conf(5))
66# MODULESD_${modulename}_EXAMPLES This is a bash array containing 99
67# a list of examples which should 100# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES

69# take a guess. Set this to "guess" 102# This is a bash array containing a list of associated aliases.
70# MODULESD_${modulename}_ALIASES This is a bash array containing 103#
71# a list of associated aliases. 104# For each array_component it's added an alias line in the modprobe.d/modules.d file
72# MODULESD_${modulename}_ADDITIONS This is a bash array containing 105#
73# A list of additional things to 106# alias array_component
74# add to the bottom of the file. 107#
75# This can be absolutely anything. 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.
76# Each entry is a new line. 114# 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
80 115
81# The order of these is important as both of linux-info and eutils contain 116# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
82# set_arch_to_kernel and set_arch_to_portage functions and the ones in eutils 117# @DESCRIPTION:
83# are deprecated in favor of the ones in linux-info. 118# This is a string list which contains the full path to any associated
84# See http://bugs.gentoo.org/show_bug.cgi?id=127506 119# documents for <modulename>. These files are installed in the live tree.
