# @SUPPORTED_EAPIS: 2 3 4 5 6
# @BLURB: Eclass for kernel packages
# @DESCRIPTION:
# This is the kernel.eclass rewrite for a clean base regarding the 2.6
# series of kernel with back-compatibility for 2.4
# Please direct your bugs to the current eclass maintainer :)
# added functionality:
# unipatch - a flexible, singular method to extract, add and remove patches.
# @ECLASS-VARIABLE: K_USEPV
# @DEFAULT_UNSET
# @DESCRIPTION:
# When setting the EXTRAVERSION variable, it should
# add PV to the end.
# this is useful for things like wolk. IE:
# EXTRAVERSION would be something like : -wolk-4.19-r1
# @ECLASS-VARIABLE: K_NOSETEXTRAVERSION
# @DEFAULT_UNSET
# @DESCRIPTION:
# if this is set then EXTRAVERSION will not be
# automatically set within the kernel Makefile
# @ECLASS-VARIABLE: K_NOUSENAME
# @DEFAULT_UNSET
# @DESCRIPTION:
# if this is set then EXTRAVERSION will not include the
# first part of ${PN} in EXTRAVERSION
# @ECLASS-VARIABLE: K_NOUSEPR
# @DEFAULT_UNSET
# @DESCRIPTION:
# if this is set then EXTRAVERSION will not include the
# anything based on ${PR}.
# @ECLASS-VARIABLE: K_PREPATCHED
# @DEFAULT_UNSET
# @DESCRIPTION:
# 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
# @ECLASS-VARIABLE: K_EXTRAEINFO
# @DEFAULT_UNSET
# @DESCRIPTION:
# this is a new-line seperated list of einfo displays in
# postinst and can be used to carry additional postinst
# messages
# @ECLASS-VARIABLE: K_EXTRAELOG
# @DEFAULT_UNSET
# @DESCRIPTION:
# same as K_EXTRAEINFO except using elog instead of einfo
# @ECLASS-VARIABLE: K_EXTRAEWARN
# @DEFAULT_UNSET
# @DESCRIPTION:
# same as K_EXTRAEINFO except using ewarn instead of einfo
# @ECLASS-VARIABLE: K_SYMLINK
# @DEFAULT_UNSET
# @DESCRIPTION:
# if this is set, then forcably create symlink anyway
# @ECLASS-VARIABLE: K_BASE_VER
# @DEFAULT_UNSET
# @DESCRIPTION:
# for git-sources, declare the base version this patch is
# based off of.
# @ECLASS-VARIABLE: K_DEFCONFIG
# @DEFAULT_UNSET
# @DESCRIPTION:
# Allow specifying a different defconfig target.
# If length zero, defaults to "defconfig".
# @ECLASS-VARIABLE: K_WANT_GENPATCHES
# @DEFAULT_UNSET
# @DESCRIPTION:
# Apply genpatches to kernel source. Provide any
# combination of "base", "extras" or "experimental".
# @ECLASS-VARIABLE: K_EXP_GENPATCHES_PULL
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set, we pull "experimental" regardless of the USE FLAG
# but expect the ebuild maintainer to use K_EXP_GENPATCHES_LIST.
# @ECLASS-VARIABLE: K_EXP_GENPATCHES_NOUSE
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set, no USE flag will be provided for "experimental";
# as a result the user cannot choose to apply those patches.
# @ECLASS-VARIABLE: K_EXP_GENPATCHES_LIST
# @DEFAULT_UNSET
# @DESCRIPTION:
# A list of patches to pick from "experimental" to apply when
# the USE flag is unset and K_EXP_GENPATCHES_PULL is set.
# @ECLASS-VARIABLE: K_FROM_GIT
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set, this variable signals that the kernel sources derives
# from a git tree and special handling will be applied so that
# any patches that are applied will actually apply.
# @ECLASS-VARIABLE: K_GENPATCHES_VER
# @DEFAULT_UNSET
# @DESCRIPTION:
# 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
# @ECLASS-VARIABLE: K_SECURITY_UNSUPPORTED
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set, this kernel is unsupported by Gentoo Security
# to the current eclass maintainer :)
# @ECLASS-VARIABLE: K_DEBLOB_AVAILABLE
# @DEFAULT_UNSET
# @DESCRIPTION:
# 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".
# @ECLASS-VARIABLE: K_DEBLOB_TAG
# @DEFAULT_UNSET
# @DESCRIPTION:
# This will be the version of deblob script. It's a upstream SVN tag
# such asw -gnu or -gnu1.
# @ECLASS-VARIABLE: K_PREDEBLOBBED
# @DEFAULT_UNSET
# @DESCRIPTION:
# This kernel was already deblobbed elsewhere.
# If false, either optional deblobbing will be available
# or the license will note the inclusion of linux-firmware code.
# @ECLASS-VARIABLE: K_LONGTERM
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set, the eclass will search for the kernel source
# in the long term directories on the upstream servers
# as the location has been changed by upstream
# @ECLASS-VARIABLE: H_SUPPORTEDARCH
# @DEFAULT_UNSET
# @DESCRIPTION:
# this should be a space separated list of ARCH's which
# can be supported by the headers ebuild
# @ECLASS-VARIABLE: UNIPATCH_LIST
# @DEFAULT_UNSET
# @DESCRIPTION:
# space delimetered list of patches to be applied to the kernel
# @ECLASS-VARIABLE: UNIPATCH_EXCLUDE
# @DEFAULT_UNSET
# @DESCRIPTION:
# An addition var to support exlusion based completely
# on "<passedstring>*" and not "<passedno#>_*"
# this should _NOT_ be used from the ebuild as this is
# reserved for end users passing excludes from the cli
# @ECLASS-VARIABLE: UNIPATCH_DOCS
# @DEFAULT_UNSET
# @DESCRIPTION:
# space delimemeted list of docs to be installed to
# the doc dir
# @ECLASS-VARIABLE: UNIPATCH_STRICTORDER
# @DEFAULT_UNSET
# @DESCRIPTION:
# if this is set places patches into directories of
# order, so they are applied in the order passed
# Changing any other variable in this eclass is not supported; you can request
# for additional variables to be added by contacting the current maintainer.
# If you do change them, there is a chance that we will not fix resulting bugs;
# that of course does not mean we're not willing to help.
