HOWTO: Kernel Compilation for Newbies

[Darth Tux]

Are you still using the guide which uses module assistant btw?
I think it's similar to nvidia driver install, create fglrx kernel module using module-assistant, then install drivers (userspace stuff) using .deb's (xorg-driver-fglrx_xx.xx and fglrx-control_xx.xx.deb).

Is that error happening when you're using module-assistant?

Yes, that is happenning while I am using module assistant to install and configure the fglrx kernel source.

Okay, here's the thing. I took a look at fglrx-kernel-source package contents and I doubt that this package could be ever built with module-assistant

Its contents are derieved from nvidia-kernel-source package, topmost changelog entry

 fglrx-kernel (3.14.6-0ubuntu1) hoary; urgency=low

  * First release; packaging derived from nvidia-kernel-source.

 -- Daniel Stone <daniel.stone@canonical.com>  Sat, 27 Nov 2004 12:52:32 +0000

Doesn't look too convincing. Then I found this

$ grep -R nvidia * | grep -v changelog:

These look nvidia specific, not ati! What the f***? Looks like a major bug to me..

You should find another way to install ati drivers. I don't have ati gfx card myself, but I was able to build kernel module using debian's fglrx-kernel-src package - that's another story though (module built succesfully). If you want to continue about this subject, send me a private message, so this thread won't go more offtopic.

I'm trying to install a driver for my pcmcia card.

in the readme it says to add a line in linux/drivers/media/video/Config.in

The Problem is I can't seem to find Config.in

I'm using Kubuntu. Is Config.in the same as KConfig?

Also, the readme says to add

dep_tristate ' ImperX Video Capture Essentials PCMCIA support'
CONFIG_PCMCIA_IMPERX_VCE $CONFIG_VIDEO_DEV $CONFIG_PCMCIA

when I add these lines to KConfig and try to make it. I get errors saying it doesn't know what dep_tristate is.

Which kernel version does the readme refer to?

[rold50]

It's refering to kernel version 2.4 something but I don't want to downgrade to 2.4..

actually I've realized that it's even impossible to downgrade the kernel to 2.4 with ubuntu (?) from reading the forums.

I have already fixed the Config.in to Kconfig conversion.

The Problem I have now is:

I have PCMCIA video grabber card.

The drivers written for it works for the 2.4 kernels.

I tried installing the drivers for the current kernel version but I get errors.

The problem lies in some of the function/member operator in the header files in 2.4 kernels is not in the latest kernel anymore.

For example in the pcmcia/ds.h There is a struct called dev_link_t, which had a member called release. In the current kernel, the release member has been omitted.

Do you think it will work fine if I just grab the old ds.h from kernel 2.4 and then building the kernel from that?

I am using dapper and was thinking to try 2.6.17 for my laptops overheating, I get dismall C3/C4 state and mostly stay in C2.

two questions here:

some reccomend here changing
CONFIG_HZ_1000 TO 25O
where and how can this be done?

when I dpkg compiled binaries, will this update grub menue too? or menu.lst needs manual editing?
will adept keep notifing and managing new updates as they are released? when booted from new kernel? when booted from old kernel?

CONFIG_HZ_1000 TO 25O

Unfortunetly am not in my LINUX box right now, but the setting is somewhere at the begining when U lunch 'make xconfig' or 'make menuconfig'
Will give U a more detailed advice once I get to my linux box.

It will auto update grub.

will adept keep notifing and managing new updates as they are released? when booted from new kernel? when booted from old kernel?

I see your a KDE junkie
Yes, adept will still be notifiying U about new updates.

thank you, that would be helpful.

right, all clear.

AFAIK porting the drivers from a kernel version to another should be a big amount of work (which btw only kernel hackers could do).

I have no idea of how to help you. Maybe you could contact via email the author of the driver and ask him whether a he released a version of the driver which compiles on modern kernels.

some reccomend here changing
CONFIG_HZ_1000 TO 25O
where and how can this be done?

cd /usr/src/linux (or the path to your kernel source)

sudo make menuconfig

get to "Processor type and features"

and look for "Timer frequency"

There you can set it to 250
