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 # Original author: John Mylchreest <johnm@gentoo.org>
9 # Maintainer: kernel-misc@gentoo.org
10 #
11 # Please direct your bugs to the current eclass maintainer :)
12
13 # added functionality:
14 # unipatch - a flexible, singular method to extract, add and remove patches.
15
16 # A Couple of env vars are available to effect usage of this eclass
17 # These are as follows:
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
23 # K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be
24 # automatically set within the kernel Makefile
25 # K_NOUSENAME - if this is set then EXTRAVERSION will not include the
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
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 # K_DEBLOB_AVAILABLE - A value of "0" will disable all of the optional deblob
49 # code. If empty, will be set to "1" if deblobbing is
50 # possible. Test ONLY for "1".
51 # K_PREDEBLOBBED - This kernel was already deblobbed elsewhere.
52 # If false, either optional deblobbing will be available
53 # or the license will note the inclusion of freedist
54 # code.
55 # K_LONGTERM - If set, the eclass will search for the kernel source
56 # in the long term directories on the upstream servers
57 # as the location has been changed by upstream
58 # H_SUPPORTEDARCH - this should be a space separated list of ARCH's which
59 # can be supported by the headers ebuild
60
61 # UNIPATCH_LIST - space delimetered list of patches to be applied to the
62 # kernel
63 # UNIPATCH_EXCLUDE - an addition var to support exlusion based completely
64 # on "<passedstring>*" and not "<passedno#>_*"
65 # - this should _NOT_ be used from the ebuild as this is
66 # reserved for end users passing excludes from the cli
67 # UNIPATCH_DOCS - space delimemeted list of docs to be installed to
68 # the doc dir
69 # UNIPATCH_STRICTORDER - if this is set places patches into directories of
70 # order, so they are applied in the order passed
