That's the way i do it, maybe it's not the best, but works always for me:
* First of all, check what is the last kernel supported by your graphics card driver - my VGA is ATI and they are always very phlegmatic with drivers. Nevermind, lets assume the latest kernel, supported by the video driver, is 2.6.30.1
* Go to http://www.kernel.org and download it. I download always full source code (its marked "F", after the date), because i keep track of the previous kernel, and don't like patching
* I have a directory, named /home/jelezarov/sources/KERNEL - just change the following commands with the appropriate paths and kernel version on your machine ($ prompt is regular user, # is root):
Code:
$ cd /home/jelezarov/sources/KERNEL
$ tar -xjvf linux-2.6.30.1.tar.bz2
$ cd linux-2.6.30.1
$ cp /boot/config-generic-smp-2.6.27.7-smp .config
the above extract the kernel sources and copies the default slackware 12.2 generic smp kernel config (it's a text file with configuration of the kernel, as the name assumes) from /boot to use as a base of our new config. After you successfully compile your kernel and all works fine, you can use the new config, when/if you compile newer kernel.
Code:
$ make silentoldconfig
This creates a new .config file, based on the configuration of the old one. You'll be asked for every new option, that is required by the new kernel. What i'm doing is just press and hold "enter"
and all goes to defaults. And since "make xconfig" makes the same - sets all unset options to default, this step is optional.
Here we will make our custom kernel adjustments, one by one. That command requires that you are in X session, otherwise use "make menuconfig", but for me that one is nicer
. When you face trouble finding something use "Edit/Find" or just Ctrl+F. When you get familiar with more kernel options, and mostly with the architecture of your machine in details, you can try to adjust more things, but for now i thing that's enough - adjust this things and leave all others to defaults. I'm following Eric Hameleers advise in that
http://alien.slackbook.org/, with the difference i'm not using the preemption thing - i tried several kernels and never see a gain in responsiveness, or even it was worst. I left that on you to decide - to set a preemption or not.
Processor type and features:
here i check "Tickless system (Dynamic Ticks)", "High resolution timer suport" and "Processor family" to "Core 2/ newer Xeon" - that will be the same for you, as you use a Quad CPU too. Next is below - if that kernel is just for your PC, you can safely uncheck "Generic X86 Support". More below is "Preemption model" - i leave that to "no", cause i like it so, but you can google it and decide for yourself. Let's go more down for one very important section - "High Memory Support" - just check "64GB" and all of your RAM will be used - i don't know exactly how that is done on 32 bit but is fact that works. The last thing we'll adjust in that section is "Timer Frequency" - set it to 300
File systems:
here you have to enable the file system you are using to be compiled in kernel, not as module - that eliminates the need of initrd image in the common case. You still will need to make an initrd if you need some special module to be loaded on boot - for example with full disk encryption (like me
). So let's assume that you use ext3 (like me), then check "Ext3 journalling file system support" - it is checked as module, mark it to be compiled in kernel. The same goes to "JBD (ext3) debugging support"
That's the minimum to be adjusted. In some cases you have to enable more modules to be compiled (i have a bluetooth keyboard for example), or there is for sure lot of things that you don't need on your PC, but i suggest you leave that for now. Now let's do:
Cause we have Quad CPUs we can safely set the -j parameter to 8 - that are the number of threads when compiling and that gives a huge speed boost when compiling the new kernel. After some waiting its finished (by me its approx. 7 min). Lets go superuser and install it:
Code:
$ su
# make modules_install
# #That put all modules in /lib/modules/'version of new kernel'/
# make kernelversion
# #That shows you the name of the new kernel
# cp arch/i386/boot/bzImage /boot/linux-generic-smp-2.6.30.1-smp
# cp System.map /boot/System.map-generic-smp-2.6.30.1-smp
# cp .config /boot/config-generic-smp-2.6.30.1-smp
# #Don't forget the "smp" string - that's what we are using
So, the kernel is installed, but lilo don't knows about that. I like vim, but you can use you preferred editor. Just be root when editing.
Code:
# vim /etc/lilo.conf
DON'T remove the current kernel lines in lilo - if something goes wrong with our new kernel we'll need the old one for troubleshoot. Let the end of lilo.conf looks something like this (adjust your names as you like it, partitions and kernel versions). Root is the partition, now mounted under /
Quote:
.....
.....
# End LILO global section
# Linux bootable partition config begins
image = /boot/vmlinuz-generic-smp-2.6.30.1-smp
root = /dev/sda3
label = NEW
read-only
# Linux bootable partition config ends
# Linux bootable partition config begins
image = /boot/vmlinuz-huge-smp-2.6.27.7-smp
root = /dev/sda3
label = OLD
read-only
# Linux bootable partition config ends
|
That writes the lilo.conf configuration to the MBR (master boot record). If there's no errors 'till now, remains just:
As we adjusted it in lilo.conf the new kernel will be booted by default, so just see if it works. If anything goes wrong reboot and select in lilo boot prompt the old kernel and your PC will be booted with him.
Good Luck!
