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.

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.

17# These are as follows: 26# These are as follows:
18# 27
19# Env Var Option Description 28# @ECLASS-VARIABLE: KERNEL_DIR
20# KERNEL_DIR <string> The directory containing kernel the target kernel 29# @DESCRIPTION:
21# sources. 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:
22# CONFIG_CHECK <string> a list of .config options to check for before 35# A string containing a list of .config options to check for before
23# proceeding with the install. ie: CONFIG_CHECK="MTRR" 36# proceeding with the install.

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
