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     # 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 dsd 1.200 # K_SECURITY_UNSUPPORTED- If set, this kernel is unsupported by Gentoo Security
48 robbat2 1.230 # 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 mpagano 1.244 # 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 johnm 1.55 # 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 lu_zero 1.62 # - this should _NOT_ be used from the ebuild as this is
66 johnm 1.55 # reserved for end users passing excludes from the cli
67 lu_zero 1.62 # UNIPATCH_DOCS - space delimemeted list of docs to be installed to
68 johnm 1.55 # the doc dir
69 lu_zero 1.62 # UNIPATCH_STRICTORDER - if this is set places patches into directories of
70 johnm 1.55 # order, so they are applied in the order passed
