IE: # EXTRAVERSION would be something like : -wolk-4.19-r1 # K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be # automatically set within the kernel Makefile # K_NOUSENAME - if this is set then EXTRAVERSION will not include the # first part of ${PN} in EXTRAVERSION # K_NOUSEPR - if this is set then EXTRAVERSION will not include the # anything based on ${PR}. # K_PREPATCHED - if the patchset is prepatched (ie: mm-sources, # ck-sources, ac-sources) it will use PR (ie: -r5) as # the patchset version for # and not use it as a true package revision # K_EXTRAEINFO - this is a new-line seperated list of einfo displays in # postinst and can be used to carry additional postinst # messages # K_EXTRAELOG - same as K_EXTRAEINFO except using elog instead of einfo # K_EXTRAEWARN - same as K_EXTRAEINFO except using ewarn instead of einfo # K_SYMLINK - if this is set, then forcably create symlink anyway # # K_DEFCONFIG - Allow specifying a different defconfig target. # If length zero, defaults to "defconfig". # K_WANT_GENPATCHES - Apply genpatches to kernel source. Provide any # combination of "base" and "extras" # K_GENPATCHES_VER - The version of the genpatches tarball(s) to apply. # A value of "5" would apply genpatches-2.6.12-5 to # my-sources-2.6.12.ebuild # K_SECURITY_UNSUPPORTED- If set, this kernel is unsupported by Gentoo Security # K_DEBLOB_AVAILABLE - A value of "0" will disable all of the optional deblob # code. If empty, will be set to "1" if deblobbing is # possible. Test ONLY for "1". # K_PREDEBLOBBED - This kernel was already deblobbed elsewhere. # If false, either optional deblobbing will be available # or the license will note the inclusion of freedist # code. # H_SUPPORTEDARCH - this should be a space separated list of ARCH's which # can be supported by the headers ebuild # UNIPATCH_LIST - space delimetered list of patches to be applied to the # kernel # UNIPATCH_EXCLUDE - an addition var to support exlusion based completely # on "*" and not "_*" # - this should _NOT_ be used from the ebuild as this is # reserved for end users passing excludes from the cli # UNIPATCH_DOCS - space delimemeted list of docs to be installed to # the doc dir # UNIPATCH_STRICTORDER - if this is set places patches into directories of # order, so they are applied in the order passed inherit eutils toolchain-funcs versionator multilib EXPORT_FUNCTIONS pkg_setup src_unpack src_compile src_install pkg_preinst pkg_postinst # Added by Daniel Ostrow # This is an ugly hack to get around an issue with a 32-bit userland on ppc64. # I will remove it when I come up with something more reasonable.
