31# They are explained properly

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

62# 93#
94# For each array_component it's added an options line in the modprobe.d file

71# MODULESD_${modulename}_ALIASES This is a bash array containing 103#
72# a list of associated aliases. 104# For each array_component it's added an alias line in the modprobe.d file
73# MODULESD_${modulename}_ADDITIONS This is a bash array containing 105#
74# A list of additional things to 106# alias array_component
75# add to the bottom of the file. 107#
76# This can be absolutely anything. 108# where array_component is "wildcard <modulename>" (see modprobe.conf(5))

77# Each entry is a new line. 114# Each entry is a new line.
78# MODULES_${modulename}_DOCS This is a string list which contains
79# the full path to any associated
80# documents for $modulename
81 115
82# The order of these is important as both of linux-info and eutils contain 116# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
83# set_arch_to_kernel and set_arch_to_portage functions and the ones in eutils 117# @DESCRIPTION:
84# are deprecated in favor of the ones in linux-info. 118# This is a string list which contains the full path to any associated
85# See http://bugs.gentoo.org/show_bug.cgi?id=127506 119# documents for <modulename>. These files are installed in the live tree.
