# @BLURB: It provides the functionality required to install external modules against a kernel source tree. |
| 12 |
# @DESCRIPTION: |
| 13 |
# This eclass is used to interface with linux-info.eclass in such a way |
| 14 |
# to provide the functionality and initial functions |
| 15 |
# required to install external modules against a kernel source |
| 16 |
# tree. |
| 17 |
|
| 18 |
# A Couple of env vars are available to effect usage of this eclass |
| 19 |
# These are as follows: |
| 20 |
|
| 21 |
# @ECLASS-VARIABLE: MODULES_OPTIONAL_USE |
| 22 |
# @DESCRIPTION: |
| 23 |
# A string containing the USE flag to use for making this eclass optional |
| 24 |
# The recommended non-empty value is 'modules' |
| 25 |
|
| 26 |
# @ECLASS-VARIABLE: KERNEL_DIR |
| 27 |
# @DESCRIPTION: |
| 28 |
# A string containing the directory of the target kernel sources. The default value is |
| 29 |
# "/usr/src/linux" |
| 30 |
|
| 31 |
# @ECLASS-VARIABLE: ECONF_PARAMS |
| 32 |
# @DESCRIPTION: |
| 33 |
# It's a string containing the parameters to pass to econf. |
| 34 |
# If this is not set, then econf isn't run. |
| 35 |
|
| 36 |
# @ECLASS-VARIABLE: BUILD_PARAMS |
| 37 |
# @DESCRIPTION: |
| 38 |
# It's a string with the parameters to pass to emake. |
| 39 |
|
| 40 |
# @ECLASS-VARIABLE: BUILD_TARGETS |
| 41 |
# @DESCRIPTION: |
| 42 |
# It's a string with the build targets to pass to make. The default value is "clean module" |
| 43 |
|
| 44 |
# @ECLASS-VARIABLE: MODULE_NAMES |
| 45 |
# @DESCRIPTION: |
| 46 |
# It's a string containing the modules to be built automatically using the default |
| 47 |
# src_compile/src_install. It will only make ${BUILD_TARGETS} once in any directory. |
| 48 |
# |
| 49 |
# The structure of each MODULE_NAMES entry is as follows: |
| 50 |
# |
| 51 |
# modulename(libdir:srcdir:objdir) |
| 52 |
# |
| 53 |
# where: |
| 54 |
# |
| 55 |
# modulename = name of the module file excluding the .ko |
| 56 |
# libdir = place in system modules directory where module is installed (by default it's misc) |
| 57 |
# srcdir = place for ebuild to cd to before running make (by default it's ${S}) |
| 58 |
# objdir = place the .ko and objects are located after make runs (by default it's set to srcdir) |
| 59 |
# |
| 60 |
# To get an idea of how these variables are used, here's a few lines |
| 61 |
# of code from around line 540 in this eclass: |
| 62 |
# |
| 63 |
# einfo "Installing ${modulename} module" |
| 64 |
# cd ${objdir} || die "${objdir} does not exist" |
| 65 |
# insinto /lib/modules/${KV_FULL}/${libdir} |
| 66 |
# doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed" |
| 67 |
# |
| 68 |
# For example: |
| 69 |
# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})" |
| 70 |
# |
| 71 |
# what this would do is |
| 72 |
# |
| 73 |
# cd "${S}"/pci |
| 74 |
# make ${BUILD_PARAMS} ${BUILD_TARGETS} |
| 75 |
# cd "${S}" |
| 76 |
# insinto /lib/modules/${KV_FULL}/pci |
| 77 |
# doins module_pci.${KV_OBJ} |
| 78 |
# |
| 79 |
# cd "${S}"/usb |
| 80 |
# make ${BUILD_PARAMS} ${BUILD_TARGETS} |
| 81 |
# cd "${S}" |
| 82 |
# insinto /lib/modules/${KV_FULL}/usb |
| 83 |
# doins module_usb.${KV_OBJ} |
| 84 |
|
| 85 |
# There is also support for automated modprobe.d file generation. |
| 86 |
# This can be explicitly enabled by setting any of the following variables. |
| 87 |
|
| 88 |
# @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED |
| 89 |
# @DESCRIPTION: |
| 90 |
# This is used to disable the modprobe.d file generation otherwise the file will be |
| 91 |
# always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable |
| 92 |
# the generation of the file and the installation of the documentation. |
| 93 |
|
| 94 |
# @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES |
| 95 |
# @DESCRIPTION: |
| 96 |
# This is a bash array containing a list of examples which should |
| 97 |
# be used. If you want us to try and take a guess set this to "guess". |
| 98 |
# |
| 99 |
# For each array_component it's added an options line in the modprobe.d file |
| 100 |
# |
| 101 |
# options array_component |
| 102 |
# |
| 103 |
# where array_component is "<modulename> options" (see modprobe.conf(5)) |
| 104 |
|
| 105 |
# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES |
| 106 |
# @DESCRIPTION: |
| 107 |
# This is a bash array containing a list of associated aliases. |
| 108 |
# |
| 109 |
# For each array_component it's added an alias line in the modprobe.d file |
| 110 |
# |
| 111 |
# alias array_component |
| 112 |
# |
| 113 |
# where array_component is "wildcard <modulename>" (see modprobe.conf(5)) |
| 114 |
|
| 115 |
# @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS |
| 116 |
# @DESCRIPTION: |
| 117 |
# This is a bash array containing a list of additional things to |
| 118 |
# add to the bottom of the file. This can be absolutely anything. |
| 119 |
# Each entry is a new line. |
| 120 |
|
| 121 |
# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS |
| 122 |
# @DESCRIPTION: |
| 123 |
# This is a string list which contains the full path to any associated |
| 124 |
# documents for <modulename>. These files are installed in the live tree. |
| 125 |
|
| 126 |
# @ECLASS-VARIABLE: KV_OBJ |
| 127 |
# @DESCRIPTION: |
| 128 |
# It's a read-only variable. It contains the extension of the kernel modules. |
