+# Description: kernel.eclass rewrite for a clean base regarding the 2.6
+# series of kernel with back-compatibility for 2.4
+#
+# Original author: John Mylchreest <jo...@gentoo.org>
+# Maintainer: kernel-m...@gentoo.org
+#
+# Please direct your bugs to the current eclass maintainer :)
+
+# added functionality:
+# unipatch - a flexible, singular method to extract, add and
remove patches.
+
+# A Couple of env vars are available to effect usage of this eclass
+# These are as follows:
+#
+# K_USEPV - When setting the EXTRAVERSION
variable, it should
+# add PV to the end.
+# this is useful for thigns
like wolk. 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",
"extras" or "experimental".
+# K_EXP_GENPATCHES_PULL - If set, we pull "experimental" regardless of
the USE FLAG
+# but expect the ebuild
maintainer to use K_EXP_GENPATCHES_LIST.
+# K_EXP_GENPATCHES_NOUSE - If set, no USE flag will be provided for
"experimental";
+# as a result the user cannot
choose to apply those patches.
+# K_EXP_GENPATCHES_LIST - A list of patches to pick from "experimental"
to apply when
+# the USE flag is unset and
K_EXP_GENPATCHES_PULL is set.
+# 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.
+# K_LONGTERM - 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
+# 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 "<passedstring>*" and not
"<passedno#>_*"
+# - 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
+
+# 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.
