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#
35# The structure of each MODULE_NAMES entry is as follows: 47# The structure of each MODULE_NAMES entry is as follows:
36# modulename(libmodulesdir:modulesourcedir) 48#
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#
37# for example: 66# For example:
38# MODULE_NAMES="module_pci(pci:${S}/pci) module_usb(usb:${S}/usb)" 67# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
39# 68#
40# what this would do is 69# what this would do is
70#
41# cd ${S}/pci 71# cd "${S}"/pci
42# make ${BUILD_PARAMS} ${BUILD_TARGETS} 72# make ${BUILD_PARAMS} ${BUILD_TARGETS}
73# cd "${S}"
43# insinto /lib/modules/${KV_FULL}/pci 74# insinto /lib/modules/${KV_FULL}/pci
44# doins module_pci.${KV_OBJ} 75# doins module_pci.${KV_OBJ}
45# 76#
46# cd ${S}/usb 77# cd "${S}"/usb
47# make ${BUILD_PARAMS} ${BUILD_TARGETS} 78# make ${BUILD_PARAMS} ${BUILD_TARGETS}
79# cd "${S}"
48# insinto /lib/modules/${KV_FULL}/usb 80# insinto /lib/modules/${KV_FULL}/usb
49# doins module_usb.${KV_OBJ} 81# doins module_usb.${KV_OBJ}
50#
51# if the modulessourcedir isnt specified, it assumes ${S}
52# if the libmodulesdir isnt specified, it assumes misc.
53# if no seperator is defined ":" then it assumes the argument is modulesourcedir
54 82
55inherit linux-info 83# There is also support for automated modprobe.d/modules.d(2.4) file generation.
56ECLASS=linux-mod 84# This can be explicitly enabled by setting any of the following variables.
57INHERITED="$INHERITED $ECLASS" 85
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".
96#
97# For each array_component it's added an options line in the modprobe.d/modules.d file
98#
99# options array_component
100#
101# where array_component is "<modulename> options" (see modprobe.conf(5))
102
103# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
104# @DESCRIPTION:
105# This is a bash array containing a list of associated aliases.
106#
107# For each array_component it's added an alias line in the modprobe.d/modules.d file
108#
109# alias array_component
110#
111# where array_component is "wildcard <modulename>" (see modprobe.conf(5))
112
113# @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
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.
117# Each entry is a new line.
118
119# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
120# @DESCRIPTION:
121# This is a string list which contains the full path to any associated
122# documents for <modulename>. These files are installed in the live tree.
123
124# @ECLASS-VARIABLE: KV_OBJ
125# @DESCRIPTION:
126# It's a read-only variable. It contains the extension of the kernel modules.
127
128# The order of these is important as both of linux-info and eutils contain
129# set_arch_to_kernel and set_arch_to_portage functions and the ones in eutils
130# are deprecated in favor of the ones in linux-info.
