# @BLURB: It provides the functionality required to install external modules against a kernel source tree.
|
|
# @DESCRIPTION:
|
|
# This eclass is used to interface with linux-info.eclass in such a way
|
|
# to provide the functionality and initial functions
|
|
# required to install external modules against a kernel source
|
|
# tree.
|
|
|
|
# A Couple of env vars are available to effect usage of this eclass
|
|
# These are as follows:
|
|
|
|
# @ECLASS-VARIABLE: MODULES_OPTIONAL_USE
|
|
# @DESCRIPTION:
|
|
# A string containing the USE flag to use for making this eclass optional
|
|
# The recommended non-empty value is 'modules'
|
|
|
|
# @ECLASS-VARIABLE: KERNEL_DIR
|
|
# @DESCRIPTION:
|
|
# A string containing the directory of the target kernel sources. The default value is
|
|
# "/usr/src/linux"
|
|
|
|
# @ECLASS-VARIABLE: ECONF_PARAMS
|
|
# @DESCRIPTION:
|
|
# It's a string containing the parameters to pass to econf.
|
|
# If this is not set, then econf isn't run.
|
|
|
|
# @ECLASS-VARIABLE: BUILD_PARAMS
|
|
# @DESCRIPTION:
|
|
# It's a string with the parameters to pass to emake.
|
|
|
|
# @ECLASS-VARIABLE: BUILD_TARGETS
|
|
# @DESCRIPTION:
|
|
# It's a string with the build targets to pass to make. The default value is "clean module"
|
|
|
|
# @ECLASS-VARIABLE: MODULE_NAMES
|
|
# @DESCRIPTION:
|
|
# It's a string containing the modules to be built automatically using the default
|
|
# src_compile/src_install. It will only make ${BUILD_TARGETS} once in any directory.
|
|
#
|
|
# The structure of each MODULE_NAMES entry is as follows:
|
|
#
|
|
# modulename(libdir:srcdir:objdir)
|
|
#
|
|
# where:
|
|
#
|
|
# modulename = name of the module file excluding the .ko
|
|
# libdir = place in system modules directory where module is installed (by default it's misc)
|
|
# srcdir = place for ebuild to cd to before running make (by default it's ${S})
|
|
# objdir = place the .ko and objects are located after make runs (by default it's set to srcdir)
|
|
#
|
|
# To get an idea of how these variables are used, here's a few lines
|
|
# of code from around line 540 in this eclass:
|
|
#
|
|
# einfo "Installing ${modulename} module"
|
|
# cd ${objdir} || die "${objdir} does not exist"
|
|
# insinto /lib/modules/${KV_FULL}/${libdir}
|
|
# doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
|
|
#
|
|
# For example:
|
|
# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
|
|
#
|
|
# what this would do is
|
|
#
|
|
# cd "${S}"/pci
|
|
# make ${BUILD_PARAMS} ${BUILD_TARGETS}
|
|
# cd "${S}"
|
|
# insinto /lib/modules/${KV_FULL}/pci
|
|
# doins module_pci.${KV_OBJ}
|
|
#
|
|
# cd "${S}"/usb
|
|
# make ${BUILD_PARAMS} ${BUILD_TARGETS}
|
|
# cd "${S}"
|
|
# insinto /lib/modules/${KV_FULL}/usb
|
|
# doins module_usb.${KV_OBJ}
|
|
|
|
# There is also support for automated modprobe.d file generation.
|
|
# This can be explicitly enabled by setting any of the following variables.
|
|
|
|
# @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED
|
|
# @DESCRIPTION:
|
|
# This is used to disable the modprobe.d file generation otherwise the file will be
|
|
# always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable
|
|
# the generation of the file and the installation of the documentation.
|
|
|
|
# @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
|
|
# @DESCRIPTION:
|
|
# This is a bash array containing a list of examples which should
|
|
# be used. If you want us to try and take a guess set this to "guess".
|
|
#
|
|
# For each array_component it's added an options line in the modprobe.d file
|
|
#
|
|
# options array_component
|
|
#
|
|
# where array_component is "<modulename> options" (see modprobe.conf(5))
|
|
|
|
# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
|
|
# @DESCRIPTION:
|
|
# This is a bash array containing a list of associated aliases.
|
|
#
|
|
# For each array_component it's added an alias line in the modprobe.d file
|
|
#
|
|
# alias array_component
|
|
#
|
|
# where array_component is "wildcard <modulename>" (see modprobe.conf(5))
|
|
|
|
# @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
|
|
# @DESCRIPTION:
|
|
# This is a bash array containing a list of additional things to
|
|
# add to the bottom of the file. This can be absolutely anything.
|
|
# Each entry is a new line.
|
|
|
|
# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
|
|
# @DESCRIPTION:
|
|
# This is a string list which contains the full path to any associated
|
|
# documents for <modulename>. These files are installed in the live tree.
|
|
|
|
# @ECLASS-VARIABLE: KV_OBJ
|
|
# @DESCRIPTION:
|
|
# It's a read-only variable. It contains the extension of the kernel modules.
