25# BUILD_PARAMS <string> The parameters to pass to emake.

28# MODULE_NAMES <string> This is the modules which are
29# to be built automatically using
30# the default pkg_compile/install.
31# They are explained properly
32# below. It will only make
33# BUILD_TARGETS once in any

35 33
36# 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
42# @ECLASS-VARIABLE: MODULE_NAMES
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.
37# 46#
38# The structure of each MODULE_NAMES entry is as follows: 47# The structure of each MODULE_NAMES entry is as follows:
48#
39# modulename(libdir:srcdir:objdir) 49# modulename(libdir:srcdir:objdir)
50#
51# where:
52#
53# modulename = name of the module file excluding the .ko
54# libdir = place in system modules directory where module is installed (by default it's misc)
55# srcdir = place for ebuild to cd to before running make (by default it's ${S})
56# objdir = place the .ko and objects are located after make runs (by default it's set to srcdir)
57#
58# To get an idea of how these variables are used, here's a few lines
59# of code from around line 540 in this eclass:
60#
61# einfo "Installing ${modulename} module"
62# cd ${objdir} || die "${objdir} does not exist"
63# insinto /lib/modules/${KV_FULL}/${libdir}
64# doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
65#
40# for example: 66# For example:
41# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})" 67# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
42# 68#
43# what this would do is 69# what this would do is
70#
44# cd ${S}/pci 71# cd "${S}"/pci
45# make ${BUILD_PARAMS} ${BUILD_TARGETS} 72# make ${BUILD_PARAMS} ${BUILD_TARGETS}
46# cd ${S} 73# cd "${S}"
47# insinto /lib/modules/${KV_FULL}/pci 74# insinto /lib/modules/${KV_FULL}/pci
48# doins module_pci.${KV_OBJ} 75# doins module_pci.${KV_OBJ}
49# 76#
50# cd ${S}/usb 77# cd "${S}"/usb
51# make ${BUILD_PARAMS} ${BUILD_TARGETS} 78# make ${BUILD_PARAMS} ${BUILD_TARGETS}
52# cd ${S} 79# cd "${S}"
53# insinto /lib/modules/${KV_FULL}/usb 80# insinto /lib/modules/${KV_FULL}/usb
54# doins module_usb.${KV_OBJ} 81# doins module_usb.${KV_OBJ}

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

87# @DESCRIPTION:
88# This is used to disable the modprobe.d/modules.d file generation otherwise the file will be

95# be used. If you want us to try and take a guess set this to "guess".
62# 96#
97# For each array_component it's added an options line in the modprobe.d/modules.d file

71# MODULESD_${modulename}_ALIASES This is a bash array containing 106#
72# a list of associated aliases. 107# For each array_component it's added an alias line in the modprobe.d/modules.d file
73# MODULESD_${modulename}_ADDITIONS This is a bash array containing 108#
74# A list of additional things to 109# alias array_component
75# add to the bottom of the file. 110#
76# This can be absolutely anything. 111# where array_component is "wildcard <modulename>" (see modprobe.conf(5))
112

114# @DESCRIPTION:
115# This is a bash array containing a list of additional things to

79# the full path to any associated 119# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
80# documents for $modulename 120# @DESCRIPTION:
121# This is a string list which contains the full path to any associated
