| 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. |

| 10 | INHERITED="$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. |
|
|
