30# They are explained properly

35# MODULE_NAMES - Detailed Overview 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

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
36# 47#
37# The structure of each MODULE_NAMES entry is as follows: 48# The structure of each MODULE_NAMES entry is as follows:
49#
38# modulename(libdir:srcdir:objdir) 50# modulename(libdir:srcdir:objdir)
51#
52# where:
53#
54# modulename = name of the module file excluding the .ko
55# libdir = place in system modules directory where module is installed:
56# srcdir = place for ebuild to cd to before running make
57# objdir = place the .ko and objects are located after make runs
58#
59# To get an idea of how these variables are used, here's a few lines
60# of code from around line 540 in this eclass:
61#
62# einfo "Installing ${modulename} module"
63# cd ${objdir} || die "${objdir} does not exist"
64# insinto /lib/modules/${KV_FULL}/${libdir}
65# doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
66#
39# for example: 67# For example:
40# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})" 68# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
41# 69#
42# what this would do is 70# what this would do is
71#
43# cd ${S}/pci 72# cd "${S}"/pci
44# make ${BUILD_PARAMS} ${BUILD_TARGETS} 73# make ${BUILD_PARAMS} ${BUILD_TARGETS}
45# cd ${S} 74# cd "${S}"
46# insinto /lib/modules/${KV_FULL}/pci 75# insinto /lib/modules/${KV_FULL}/pci
47# doins module_pci.${KV_OBJ} 76# doins module_pci.${KV_OBJ}
48# 77#
49# cd ${S}/usb 78# cd "${S}"/usb
50# make ${BUILD_PARAMS} ${BUILD_TARGETS} 79# make ${BUILD_PARAMS} ${BUILD_TARGETS}

52# insinto /lib/modules/${KV_FULL}/usb 81# insinto /lib/modules/${KV_FULL}/usb
53# doins module_usb.${KV_OBJ} 82# doins module_usb.${KV_OBJ}

87# @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED
88# @DESCRIPTION:
89# This is used to disable the modprobe.d/modules.d file generation otherwise the file will be
90# always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable
91# the generation of the file and the installation of the documentation.
92
93# @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
94# @DESCRIPTION:
95# This is a bash array containing a list of examples which should
96# be used. If you want us to try and take a guess set this to "guess".
61# 97#
98# For each array_component it's added an options line in the modprobe.d/modules.d file
62# 99#
63# MODULESD_${modulename}_ENABLED This enables the modules.d file 100# options array_component
64# generation even if we dont 101#
65# specify any additional info. 102# where array_component is "<modulename> options" (see modprobe.conf(5))
66# MODULESD_${modulename}_EXAMPLES This is a bash array containing 103
67# a list of examples which should 104# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
68# be used. If you want us to try and 105# @DESCRIPTION:
69# take a guess. Set this to "guess" 106# This is a bash array containing a list of associated aliases.
70# MODULESD_${modulename}_ALIASES This is a bash array containing 107#
71# a list of associated aliases. 108# For each array_component it's added an alias line in the modprobe.d/modules.d file
72# MODULESD_${modulename}_ADDITIONS This is a bash array containing 109#
73# A list of additional things to 110# alias array_component
74# add to the bottom of the file. 111#
75# This can be absolutely anything. 112# where array_component is "wildcard <modulename>" (see modprobe.conf(5))
113
114# @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
115# @DESCRIPTION:
116# This is a bash array containing a list of additional things to
117# add to the bottom of the file. This can be absolutely anything.
76# Each entry is a new line. 118# 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
80 119
120# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
121# @DESCRIPTION:
122# This is a string list which contains the full path to any associated
123# documents for <modulename>. These files are installed in the live tree.
