35# MODULE_NAMES - Detailed Overview 36# @ECLASS-VARIABLE: BUILD_PARAMS
37# @DESCRIPTION:
38# It's a string with the parameters to pass to emake.
39
40# @ECLASS-VARIABLE: BUILD_TARGETS
41# @DESCRIPTION:
42# It's a string with the build targets to pass to make. The default value is "clean module"
43
44# @ECLASS-VARIABLE: MODULE_NAMES
45# @DESCRIPTION:
46# It's a string containing the modules to be built automatically using the default
47# src_compile/src_install. It will only make ${BUILD_TARGETS} once in any directory.
36# 48#
37# The structure of each MODULE_NAMES entry is as follows: 49# The structure of each MODULE_NAMES entry is as follows:
50#
38# modulename(libdir:srcdir:objdir) 51# modulename(libdir:srcdir:objdir)
52#
53# where:
54#
55# modulename = name of the module file excluding the .ko
56# libdir = place in system modules directory where module is installed (by default it's misc)
57# srcdir = place for ebuild to cd to before running make (by default it's ${S})
58# objdir = place the .ko and objects are located after make runs (by default it's set to srcdir)
59#
60# To get an idea of how these variables are used, here's a few lines
61# of code from around line 540 in this eclass:
62#
63# einfo "Installing ${modulename} module"
64# cd ${objdir} || die "${objdir} does not exist"
65# insinto /lib/modules/${KV_FULL}/${libdir}
66# doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
67#
39# for example: 68# For example:
40# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})" 69# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
41# 70#
42# what this would do is 71# what this would do is
72#
43# cd ${S}/pci 73# cd "${S}"/pci
44# make ${BUILD_PARAMS} ${BUILD_TARGETS} 74# make ${BUILD_PARAMS} ${BUILD_TARGETS}
45# cd ${S} 75# cd "${S}"
46# insinto /lib/modules/${KV_FULL}/pci 76# insinto /lib/modules/${KV_FULL}/pci
47# doins module_pci.${KV_OBJ} 77# doins module_pci.${KV_OBJ}
48# 78#
49# cd ${S}/usb 79# cd "${S}"/usb
50# make ${BUILD_PARAMS} ${BUILD_TARGETS} 80# make ${BUILD_PARAMS} ${BUILD_TARGETS}
51# cd ${S} 81# cd "${S}"
52# insinto /lib/modules/${KV_FULL}/usb 82# insinto /lib/modules/${KV_FULL}/usb
53# doins module_usb.${KV_OBJ} 83# doins module_usb.${KV_OBJ}

89# @DESCRIPTION:
90# This is used to disable the modprobe.d file generation otherwise the file will be

94# @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
95# @DESCRIPTION:
96# This is a bash array containing a list of examples which should
97# be used. If you want us to try and take a guess set this to "guess".
61# 98#
99# For each array_component it's added an options line in the modprobe.d file
62# 100#
63# MODULESD_${modulename}_ENABLED This enables the modules.d file 101# options array_component

65# specify any additional info. 103# where array_component is "<modulename> options" (see modprobe.conf(5))
66# MODULESD_${modulename}_EXAMPLES This is a bash array containing 104
67# a list of examples which should 105# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES

69# take a guess. Set this to "guess" 107# This is a bash array containing a list of associated aliases.
70# MODULESD_${modulename}_ALIASES This is a bash array containing 108#
71# a list of associated aliases. 109# For each array_component it's added an alias line in the modprobe.d file
72# MODULESD_${modulename}_ADDITIONS This is a bash array containing 110#
73# A list of additional things to 111# alias array_component
74# add to the bottom of the file. 112#
75# This can be absolutely anything. 113# where array_component is "wildcard <modulename>" (see modprobe.conf(5))

115# @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
116# @DESCRIPTION:
117# This is a bash array containing a list of additional things to

76# Each entry is a new line. 119# 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
80 120
81# The order of these is important as both of linux-info and eutils contain 121# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
82# set_arch_to_kernel and set_arch_to_portage functions and the ones in eutils 122# @DESCRIPTION:
83# are deprecated in favor of the ones in linux-info. 123# This is a string list which contains the full path to any associated
84# See http://bugs.gentoo.org/show_bug.cgi?id=127506 124# documents for <modulename>. These files are installed in the live tree.
