5 johnm 1.54 # Description: kernel.eclass rewrite for a clean base regarding the 2.6
6     # series of kernel with back-compatibility for 2.4

10 johnm 1.3 #
11     # Please direct your bugs to the current eclass maintainer :)
12 johnm 1.1
13     # added functionality:
14     # unipatch - a flexible, singular method to extract, add and remove patches.
15    
16 johnm 1.54 # A Couple of env vars are available to effect usage of this eclass
17 johnm 1.1 # These are as follows:
18     #
19 johnm 1.93 # 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 johnm 1.55 # 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 robbat2 1.163 # K_NOUSEPR - if this is set then EXTRAVERSION will not include the
28     # anything based on ${PR}.
29 lu_zero 1.62 # 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 johnm 1.93 # and not use it as a true package revision
33 johnm 1.55 # K_EXTRAEINFO - this is a new-line seperated list of einfo displays in
34 lu_zero 1.62 # postinst and can be used to carry additional postinst
35 johnm 1.55 # messages
36 zlin 1.208 # 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 johnm 1.107 # K_SYMLINK - if this is set, then forcably create symlink anyway
39 plasmaroo 1.105 #
40 johnm 1.108 # K_DEFCONFIG - Allow specifying a different defconfig target.
41     # If length zero, defaults to "defconfig".
42 dsd 1.126 # K_WANT_GENPATCHES - Apply genpatches to kernel source. Provide any
43 tomwij 1.288 # combination of "base", "extras" or "experimental".
44     # K_EXP_GENPATCHES_PULL - If set, we pull "experimental" regardless of the USE FLAG
45     # but expect the ebuild maintainer to use K_EXP_GENPATCHES_LIST.
46     # K_EXP_GENPATCHES_NOUSE - If set, no USE flag will be provided for "experimental";
47     # as a result the user cannot choose to apply those patches.
48     # K_EXP_GENPATCHES_LIST - A list of patches to pick from "experimental" to apply when
49     # the USE flag is unset and K_EXP_GENPATCHES_PULL is set.
50 dsd 1.126 # K_GENPATCHES_VER - The version of the genpatches tarball(s) to apply.
51     # A value of "5" would apply genpatches-2.6.12-5 to
52     # my-sources-2.6.12.ebuild
53 dsd 1.200 # K_SECURITY_UNSUPPORTED- If set, this kernel is unsupported by Gentoo Security
54 robbat2 1.230 # K_DEBLOB_AVAILABLE - A value of "0" will disable all of the optional deblob
55     # code. If empty, will be set to "1" if deblobbing is
56     # possible. Test ONLY for "1".
57     # K_PREDEBLOBBED - This kernel was already deblobbed elsewhere.
58     # If false, either optional deblobbing will be available
59     # or the license will note the inclusion of freedist
60     # code.
61 mpagano 1.244 # K_LONGTERM - If set, the eclass will search for the kernel source
62 ulm 1.249 # in the long term directories on the upstream servers
63 mpagano 1.244 # as the location has been changed by upstream
64 johnm 1.55 # H_SUPPORTEDARCH - this should be a space separated list of ARCH's which
65     # can be supported by the headers ebuild
66    
67     # UNIPATCH_LIST - space delimetered list of patches to be applied to the
68     # kernel
69     # UNIPATCH_EXCLUDE - an addition var to support exlusion based completely
70     # on "<passedstring>*" and not "<passedno#>_*"
71 lu_zero 1.62 # - this should _NOT_ be used from the ebuild as this is
72 johnm 1.55 # reserved for end users passing excludes from the cli
73 lu_zero 1.62 # UNIPATCH_DOCS - space delimemeted list of docs to be installed to
74 johnm 1.55 # the doc dir
75 lu_zero 1.62 # UNIPATCH_STRICTORDER - if this is set places patches into directories of
76 johnm 1.55 # order, so they are applied in the order passed
77 johnm 1.1
78 tomwij 1.282 # Changing any other variable in this eclass is not supported; you can request
79     # for additional variables to be added by contacting the current maintainer.
80     # If you do change them, there is a chance that we will not fix resulting bugs;
81     # that of course does not mean we're not willing to help.
