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

34 33
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
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.
36# 46#
37# The structure of each MODULE_NAMES entry is as follows: 47# The structure of each MODULE_NAMES entry is as follows:
48#
38# 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#
39# for example: 66# For example:
40# 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})"
41# 68#
42# what this would do is 69# what this would do is
70#
43# cd ${S}/pci 71# cd "${S}"/pci
44# make ${BUILD_PARAMS} ${BUILD_TARGETS} 72# make ${BUILD_PARAMS} ${BUILD_TARGETS}
45# cd ${S} 73# cd "${S}"
46# insinto /lib/modules/${KV_FULL}/pci 74# insinto /lib/modules/${KV_FULL}/pci
47# doins module_pci.${KV_OBJ} 75# doins module_pci.${KV_OBJ}
48# 76#
49# cd ${S}/usb 77# cd "${S}"/usb
50# make ${BUILD_PARAMS} ${BUILD_TARGETS} 78# make ${BUILD_PARAMS} ${BUILD_TARGETS}
51# cd ${S} 79# cd "${S}"
52# insinto /lib/modules/${KV_FULL}/usb 80# insinto /lib/modules/${KV_FULL}/usb
53# doins module_usb.${KV_OBJ} 81# doins module_usb.${KV_OBJ}

86# @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED
87# @DESCRIPTION:
88# This is used to disable the modprobe.d/modules.d file generation otherwise the file will be
89# always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable
90# the generation of the file and the installation of the documentation.
91
92# @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
93# @DESCRIPTION:
94# This is a bash array containing a list of examples which should
95# be used. If you want us to try and take a guess set this to "guess".
61# 96#
97# For each array_component it's added an options line in the modprobe.d/modules.d file
62# 98#
63# MODULESD_${modulename}_ENABLED This enables the modules.d file 99# options array_component
64# generation even if we dont 100#
65# specify any additional info. 101# where array_component is "<modulename> options" (see modprobe.conf(5))
66# MODULESD_${modulename}_EXAMPLES This is a bash array containing 102
67# a list of examples which should 103# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES

69# take a guess. Set this to "guess" 105# This is a bash array containing a list of associated aliases.
70# MODULESD_${modulename}_ALIASES This is a bash array containing 106#
71# a list of associated aliases. 107# For each array_component it's added an alias line in the modprobe.d/modules.d file
72# MODULESD_${modulename}_ADDITIONS This is a bash array containing 108#
73# A list of additional things to 109# alias array_component
74# add to the bottom of the file. 110#
75# 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
116# add to the bottom of the file. This can be absolutely anything.
76# Each entry is a new line. 117# Each entry is a new line.

78# the full path to any associated
79# documents for $modulename
80 118
119# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
