Default value is unset (false). True represented by 1 or 'on', other # values including unset treated as false. # @ECLASS_VARIABLE: KERNEL_DIR # @DESCRIPTION: # A string containing the directory of the target kernel sources. The default value is # "/usr/src/linux" : ${KERNEL_DIR:=/usr/src/linux} # @ECLASS_VARIABLE: ECONF_PARAMS # @DEFAULT_UNSET # @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 # @DEFAULT_UNSET # @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" : ${BUILD_TARGETS:=clean module} # @ECLASS_VARIABLE: MODULE_NAMES # @DEFAULT_UNSET # @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 # @DEFAULT_UNSET # @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 # @DEFAULT_UNSET # @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 # @DEFAULT_UNSET # @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 # @DEFAULT_UNSET # @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 # @DEFAULT_UNSET # @DESCRIPTION: # This is a string list which contains the full path to any associated # documents for <modulename>.
