16# These are as follows: 22# These are as follows:
17#
18# Env Var Option Default Description
19# KERNEL_DIR <string> /usr/src/linux The directory containing kernel
20# the target kernel sources.
21# BUILD_PARAMS <string> The parameters to pass to make.
22# BUILD_TARGETS <string> clean modules The build targets to pass to make.
23# MODULE_NAMES <string> This is the modules which are
24# to be built automatically using the
25# default pkg_compile/install. They
26# are explained properly below.
27# It will only make BUILD_TARGETS once
28# in any directory.
29# NO_MODULESD <string> Set this to something to prevent
30# modulesd file generation
31 23
24# @ECLASS-VARIABLE: KERNEL_DIR
25# @DESCRIPTION:
26# A string containing the directory of the target kernel sources. The default value is
27# "/usr/src/linux"
32 28
33# MODULE_NAMES - Detailed Overview 29# @ECLASS-VARIABLE: ECONF_PARAMS
34# 30# @DESCRIPTION:
31# It's a string containing the parameters to pass to econf.
32# If this is not set, then econf isn't run.
33
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.
46
47#
35# The structure of each MODULE_NAMES entry is as follows: 48# The structure of each MODULE_NAMES entry is as follows:
36# modulename(libmodulesdir:modulesourcedir) 49#
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#
37# for example: 67# For example:
38# MODULE_NAMES="module_pci(pci:${S}/pci) module_usb(usb:${S}/usb)" 68# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
39# 69#
40# what this would do is 70# what this would do is
71#
41# cd ${S}/pci 72# cd "${S}"/pci
42# make ${BUILD_PARAMS} ${BUILD_TARGETS} 73# make ${BUILD_PARAMS} ${BUILD_TARGETS}
74# cd "${S}"
43# insinto /lib/modules/${KV_FULL}/pci 75# insinto /lib/modules/${KV_FULL}/pci
44# doins module_pci.${KV_OBJ} 76# doins module_pci.${KV_OBJ}
45# 77#
46# cd ${S}/usb 78# cd "${S}"/usb
47# make ${BUILD_PARAMS} ${BUILD_TARGETS} 79# make ${BUILD_PARAMS} ${BUILD_TARGETS}
80# cd "${S}"
48# insinto /lib/modules/${KV_FULL}/usb 81# insinto /lib/modules/${KV_FULL}/usb
49# doins module_usb.${KV_OBJ} 82# doins module_usb.${KV_OBJ}
50#
51# if the modulessourcedir isnt specified, it assumes ${S}
52# if the libmodulesdir isnt specified, it assumes misc.
53# if no seperator is defined ":" then it assumes the argument is modulesourcedir
54 83
55inherit linux-info 84# There is also support for automated modprobe.d/modules.d(2.4) file generation.
56ECLASS=linux-mod 85# This can be explicitly enabled by setting any of the following variables.
57INHERITED="$INHERITED $ECLASS" 86
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".
97#
98# For each array_component it's added an options line in the modprobe.d/modules.d file
99#
100# options array_component
101#
102# where array_component is "<modulename> options" (see modprobe.conf(5))
103
104# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
105# @DESCRIPTION:
106# This is a bash array containing a list of associated aliases.
107#
108# For each array_component it's added an alias line in the modprobe.d/modules.d file
109#
110# alias array_component
111#
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.
118# Each entry is a new line.
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.
124
125# @ECLASS-VARIABLE: KV_OBJ
126# @DESCRIPTION:
127# It's a read-only variable. It contains the extension of the kernel modules.
128
129# The order of these is important as both of linux-info and eutils contain
130# set_arch_to_kernel and set_arch_to_portage functions and the ones in eutils
131# are deprecated in favor of the ones in linux-info.
