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.

9ECLASS=linux-info 16# A Couple of env vars are available to effect usage of this eclass
10INHERITED="$INHERITED $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# To simply warn about a missing option, prepend a '~'.
28# ERROR_CFG <string> The error message to display when the above check
29# fails. <CFG> should reference the appropriate option
30# as above. ie: ERROR_MTRR="MTRR exists in the .config
31# but shouldn't!!"
32# KBUILD_OUTPUT <string> This is passed on commandline, or can be set from
33# the kernel makefile. This contains the directory
34# which is to be used as the kernel object directory.
35
36# There are also a couple of variables which are set by this, and shouldn't be
37# set by hand. These are as follows:
38#
39# Env Var Option Description
40# KV_FULL <string> The full kernel version. ie: 2.6.9-gentoo-johnm-r1
41# KV_MAJOR <integer> The kernel major version. ie: 2
42# KV_MINOR <integer> The kernel minor version. ie: 6
43# KV_PATCH <integer> The kernel patch version. ie: 9
44# KV_EXTRA <string> The kernel EXTRAVERSION. ie: -gentoo
45# KV_LOCAL <string> The kernel LOCALVERSION concatenation. ie: -johnm
46# KV_DIR <string> The kernel source directory, will be null if
47# KERNEL_DIR is invalid.
48# KV_OUT_DIR <string> The kernel object directory. will be KV_DIR unless
49# koutput is used. This should be used for referencing
50# .config.
