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