14# These are as follows: 17# These are as follows:
15# 18#
19# K_USEPV - When setting the EXTRAVERSION variable, it should
20# add PV to the end.
21# this is useful for thigns like wolk. IE:
22# EXTRAVERSION would be something like : -wolk-4.19-r1
16# K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be automatically set within the kernel Makefile 23# K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be
24# automatically set within the kernel Makefile
17# K_NOUSENAME - if this is set then EXTRAVERSION will not include the first part of ${PN} in EXTRAVERSION 25# K_NOUSENAME - if this is set then EXTRAVERSION will not include the
18# K_EXTRAEINFO - this is a new-line seperated list of einfo displays in postinst and can be used to carry additional postinst messages 26# first part of ${PN} in EXTRAVERSION
27# K_NOUSEPR - if this is set then EXTRAVERSION will not include the
28# anything based on ${PR}.
29# K_PREPATCHED - if the patchset is prepatched (ie: mm-sources,
30# ck-sources, ac-sources) it will use PR (ie: -r5) as
31# the patchset version for
32# and not use it as a true package revision
33# K_EXTRAEINFO - this is a new-line seperated list of einfo displays in
34# postinst and can be used to carry additional postinst
35# messages
36# K_EXTRAELOG - same as K_EXTRAEINFO except using elog instead of einfo
19# K_EXTRAEWARN - same as K_EXTRAEINFO except ewarn's instead of einfo's 37# K_EXTRAEWARN - same as K_EXTRAEINFO except using ewarn instead of einfo
38# K_SYMLINK - if this is set, then forcably create symlink anyway
39#
40# K_DEFCONFIG - Allow specifying a different defconfig target.
41# If length zero, defaults to "defconfig".
42# K_WANT_GENPATCHES - Apply genpatches to kernel source. Provide any
43# combination of "base" and "extras"
44# K_GENPATCHES_VER - The version of the genpatches tarball(s) to apply.
45# A value of "5" would apply genpatches-2.6.12-5 to
46# my-sources-2.6.12.ebuild
47# K_SECURITY_UNSUPPORTED- If set, this kernel is unsupported by Gentoo Security
48
49# H_SUPPORTEDARCH - this should be a space separated list of ARCH's which
50# can be supported by the headers ebuild
51
20# UNIPATCH_LIST - space delimetered list of patches to be applied to the kernel 52# UNIPATCH_LIST - space delimetered list of patches to be applied to the
53# kernel
54# UNIPATCH_EXCLUDE - an addition var to support exlusion based completely
55# on "<passedstring>*" and not "<passedno#>_*"
56# - this should _NOT_ be used from the ebuild as this is
57# reserved for end users passing excludes from the cli
21# UNIPATCH_DOCS - space delimemeted list of docs to be installed to the doc dir 58# UNIPATCH_DOCS - space delimemeted list of docs to be installed to
59# the doc dir
60# UNIPATCH_STRICTORDER - if this is set places patches into directories of
61# order, so they are applied in the order passed
