13# @BLURB: eclass used for accessing kernel related information
14# @DESCRIPTION:
15# This eclass is used as a central eclass for accessing kernel
16# related information for source or binary already installed.
17# It is vital for linux-mod.eclass to function correctly, and is split
18# out so that any ebuild behaviour "templates" are abstracted out
19# using additional eclasses.
20#
21# "kernel config" in this file means:
22# The .config of the currently installed sources is used as the first
23# preference, with a fall-back to bundled config (/proc/config.gz) if available.
24
25# A Couple of env vars are available to effect usage of this eclass
26# These are as follows:
27
28# @ECLASS-VARIABLE: KERNEL_DIR
29# @DESCRIPTION:
30# A string containing the directory of the target kernel sources. The default value is
31# "/usr/src/linux"
32
33# @ECLASS-VARIABLE: CONFIG_CHECK
34# @DESCRIPTION:
35# A string containing a list of .config options to check for before
36# proceeding with the install.
37#
38# e.g.: CONFIG_CHECK="MTRR"
39#
40# You can also check that an option doesn't exist by
41# prepending it with an exclamation mark (!).
42#
43# e.g.: CONFIG_CHECK="!MTRR"
44#
45# To simply warn about a missing option, prepend a '~'.
46# It may be combined with '!'.
47#
48# In general, most checks should be non-fatal. The only time fatal checks should
49# be used is for building kernel modules or cases that a compile will fail
50# without the option.
51#
52# This is to allow usage of binary kernels, and minimal systems without kernel
53# sources.
54
55# @ECLASS-VARIABLE: ERROR_<CFG>
56# @DESCRIPTION:
57# A string containing the error message to display when the check against CONFIG_CHECK
58# fails. <CFG> should reference the appropriate option used in CONFIG_CHECK.
59#
60# e.g.: ERROR_MTRR="MTRR exists in the .config but shouldn't!!"
61
62# @ECLASS-VARIABLE: KBUILD_OUTPUT
63# @DESCRIPTION:
64# A string passed on commandline, or set from the kernel makefile. It contains the directory
65# which is to be used as the kernel object directory.
66
67# There are also a couple of variables which are set by this, and shouldn't be
68# set by hand. These are as follows:
69
70# @ECLASS-VARIABLE: KV_FULL
71# @DESCRIPTION:
72# A read-only variable. It's a string containing the full kernel version. ie: 2.6.9-gentoo-johnm-r1
73
74# @ECLASS-VARIABLE: KV_MAJOR
75# @DESCRIPTION:
76# A read-only variable. It's an integer containing the kernel major version. ie: 2
77
78# @ECLASS-VARIABLE: KV_MINOR
79# @DESCRIPTION:
80# A read-only variable. It's an integer containing the kernel minor version. ie: 6
81
82# @ECLASS-VARIABLE: KV_PATCH
83# @DESCRIPTION:
84# A read-only variable. It's an integer containing the kernel patch version. ie: 9
85
86# @ECLASS-VARIABLE: KV_EXTRA
87# @DESCRIPTION:
88# A read-only variable. It's a string containing the kernel EXTRAVERSION. ie: -gentoo
89
90# @ECLASS-VARIABLE: KV_LOCAL
91# @DESCRIPTION:
92# A read-only variable. It's a string containing the kernel LOCALVERSION concatenation. ie: -johnm
93
94# @ECLASS-VARIABLE: KV_DIR
95# @DESCRIPTION:
96# A read-only variable. It's a string containing the kernel source directory, will be null if
97# KERNEL_DIR is invalid.
98
99# @ECLASS-VARIABLE: KV_OUT_DIR
100# @DESCRIPTION:
101# A read-only variable. It's a string containing the kernel object directory, will be KV_DIR unless
102# KBUILD_OUTPUT is used. This should be used for referencing .config.
103
104# And to ensure all the weirdness with crosscompile
