5# This eclass provides functions for querying the installed kernel 5# Description: This eclass is used as a central eclass for accessing kernel
6# source version, selected kernel options etc. 6# related information for sources already installed.
7# It is vital for linux-mod to function correctly, and is split
8# out so that any ebuild behaviour "templates" are abstracted out
9# using additional eclasses.

14# Please direct your bugs to the current eclass maintainer :)

16# A Couple of env vars are available to effect usage of this eclass
17# These are as follows:
18#
19# Env Var Option Description
20# KERNEL_DIR <string> The directory containing kernel the target kernel
21# sources.
22# CONFIG_CHECK <string> a list of .config options to check for before
23# proceeding with the install. ie: CONFIG_CHECK="MTRR"
24# You can also check that an option doesn't exist by
25# prepending it with an exclamation mark (!).
26# ie: CONFIG_CHECK="!MTRR"
27# <CFG>_ERROR <string> The error message to display when the above check
28# fails. <CFG> should reference the appropriate option
29# as above. ie: MTRR_ERROR="MTRR exists in the .config
30# but shouldn't!!"
31# KBUILD_OUTPUT <string> This is passed on commandline, or can be set from
32# the kernel makefile. This contains the directory
33# which is to be used as the kernel object directory.
34
35# There are also a couple of variables which are set by this, and shouldn't be
36# set by hand. These are as follows:
37#
38# Env Var Option Description
39# KV_FULL <string> The full kernel version. ie: 2.6.9-gentoo-johnm-r1
40# KV_MAJOR <integer> The kernel major version. ie: 2
41# KV_MINOR <integer> The kernel minor version. ie: 6
42# KV_PATCH <integer> The kernel patch version. ie: 9
43# KV_EXTRA <string> The kernel EXTRAVERSION. ie: -gentoo
44# KV_LOCAL <string> The kernel LOCALVERSION concatenation. ie: -johnm
45# KV_DIR <string> The kernel source directory, will be null if
46# KERNEL_DIR is invalid.
47# KV_OUT_DIR <string> The kernel object directory. will be KV_DIR unless
48# koutput is used. This should be used for referencing
49# .config.
