5 # Description: kernel.eclass rewrite for a clean base regarding the 2.6
6 # series of kernel with back-compatibility for 2.4
7 #
8 # Maintainer: John Mylchreest <johnm@gentoo.org>
9 #
10 # Please direct your bugs to the current eclass maintainer :)
11
12 # added functionality:
13 # unipatch - a flexible, singular method to extract, add and remove patches.
14
15 # A Couple of env vars are available to effect usage of this eclass
16 # These are as follows:
17 #
18 # K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be
19 # automatically set within the kernel Makefile
20 # K_NOUSENAME - if this is set then EXTRAVERSION will not include the
21 # first part of ${PN} in EXTRAVERSION
22 # K_PREPATCHED - if the patchset is prepatched (ie: mm-sources,
23 # ck-sources, ac-sources) it will use PR (ie: -r5) as
24 # the patchset version for
25 # - and not use it as a true package revision
26 # K_EXTRAEINFO - this is a new-line seperated list of einfo displays in
27 # postinst and can be used to carry additional postinst
28 # messages
29 # K_EXTRAEWARN - same as K_EXTRAEINFO except ewarn's instead of einfo's
30
31 # H_SUPPORTEDARCH - this should be a space separated list of ARCH's which
32 # can be supported by the headers ebuild
33
34 # UNIPATCH_LIST - space delimetered list of patches to be applied to the
35 # kernel
36 # UNIPATCH_EXCLUDE - an addition var to support exlusion based completely
37 # on "<passedstring>*" and not "<passedno#>_*"
38 # - this should _NOT_ be used from the ebuild as this is
39 # reserved for end users passing excludes from the cli
40 # UNIPATCH_DOCS - space delimemeted list of docs to be installed to
41 # the doc dir
42 # UNIPATCH_STRICTORDER - if this is set places patches into directories of
43 # order, so they are applied in the order passed
