1 Hello Mageia Users,
2
3 linux-userspace-headers contains the headers for the source code of
4 Linux kernel. All source code necessary to compile a new kernel is
5 included in two packages linux-userspace-headers, and kernel-source.
6 You will need to install both linux-userspace-headers (needed for
7 general Linux compilation), and kernel-source in order to compile
8 a new kernel.
9
10 The kernel is the central process of your Linux machine, the mediator
11 between the hardware and your programs. It is responsible for memory
12 allocations, process managing, device access...
13
14 Although modern kernels are very flexible thanks to dynamic modules, you
15 may need to compile your own kernel for various reasons: your found a
16 new module which need a more recent kernel, you need a feature of a new
17 kernel, etc...
18
19 Here is a short sum-up of what you can find in the Kernel-HOWTO. Consult
20 it in case of a problem or if the shortcut here provided does not meet
21 your needs. You should also consult the README of kernel-sources.
22
23
24
25 1. Configure your new kernel
26
27 You should never build a kernel as root, so as a normal user:
28 Copy the source in /usr/src/linux/ to ~/kernel/
29 Change to ~/kernel/ and clean-up previous compilations, by issuing
30 "make mrproper",
31 In console mode, run "make menuconfig",
32 Under X11, run "make xconfig".
33
34 Then configure all sections of your kernel making each feature you need
35 available constantly or as a module. Note that you should compile most
36 features as a module, as it consume less memory, taking into account
37 that some of them cannot be modules as you may need them at boot time,
38 before dynamic modules be loaded...
39
40
41
42 2. Compile it
43
44 Just issue "make" to create a compressed kernel image and the modules you
45 configured.
46
47
48
49 3. install your new kernel
50
51 Now you need root privilegies, so:
52 Issue "su" and enter root password.
53 Issue "make modules_install"
54
55 This will copy your modules and needed files to /lib/modules/
56
57 Issue "make install"
58
59 This will copy your new kernel and system.map to boot dir (/boot/) with
60 correct names including version, and change respective links.
61
62 It finally runs lilo to take into account your new kernel.
63
64
65
66 4. Modify Lilo to allow your booting on old kernel
67
68 * This step is optional, although recommended *
69 See lilo.conf man page.
70 Your are encouraged during this step to create a new section in your
71 lilo.conf file, in order to enable you to boot on your both kernels, the
72 old and the new one.
73 You need to run lilo then to take your changes into account.
74 You may also use linuxconf to do all that with a nice GUI.
75
76
77
78 5. Reboot your machine...
79
80 And pray.
81 Anyway if something goes wrong, you just need to reboot and choose your
82 old kernel with lilo.
83
84 Enjoy!
