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

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_PREPATCHED - if the patchset is prepatched (ie: mm-sources,
28 # ck-sources, ac-sources) it will use PR (ie: -r5) as
29 # the patchset version for
30 # and not use it as a true package revision
31 # K_EXTRAEINFO - this is a new-line seperated list of einfo displays in
32 # postinst and can be used to carry additional postinst
33 # messages
34 # K_EXTRAEWARN - same as K_EXTRAEINFO except ewarn's instead of einfo's
35 # K_SYMLINK - if this is set, then forcably create symlink anyway
36 #
37 # K_DEFCONFIG - Allow specifying a different defconfig target.
38 # If length zero, defaults to "defconfig".
39
40 # H_SUPPORTEDARCH - this should be a space separated list of ARCH's which
41 # can be supported by the headers ebuild
42
43 # UNIPATCH_LIST - space delimetered list of patches to be applied to the
44 # kernel
45 # UNIPATCH_EXCLUDE - an addition var to support exlusion based completely
46 # on "<passedstring>*" and not "<passedno#>_*"
47 # - this should _NOT_ be used from the ebuild as this is
48 # reserved for end users passing excludes from the cli
49 # UNIPATCH_DOCS - space delimemeted list of docs to be installed to
50 # the doc dir
51 # UNIPATCH_STRICTORDER - if this is set places patches into directories of
52 # order, so they are applied in the order passed
