Hardware :: Running System To Kernel Config
Sep 21, 2010
I've read about some sort of tools that help with kernel configuration.Can anyone tell me anything about these?It seems that you use the tool(s) on a running system. You use the running system for a while. The tool(s) gathers data and leaves bread crumbs. The tool(s) then process the bread crumbs to create a candidate config file for a fresh kernel build. The goal is a kernel build that contains parts you actually use and omits parts you don't use or don't need -- all the while using arcane knowledge of dependencies among various kernel features to (hopefully) avoid building a still-born kernel.

I accidentally deleted my .config for my kernel configuration on Linux, and seem to remember there was a way to retrieve the kernel configuration via the proc filesystem somehow. Is this still possible, and if so how would I do it?

I'm looking to extract a config from a working kernel..that much was pretty easy..all ya gotta do is "cp /proc/config.gz ." which will put it in whatever directory you're currently in and then do a "gzip -d config.gz" to get the config file.
Now...after that it gets a bit tricky..Linus says you should never compile a kernel in /usr/src/ because those header files in ../include should never change. He says you should extract a new kernel gz in your home directory and compile it there. I tend to agree (who am I to argue?). Anyway..whereever your sources are this is where you need to copy the config file...
Like this...my home dir is "/home/dart". So I would put the kernel sources there under "/home/dart/linux". I would cd to /home/dart/linux and do "cp /proc/config.gz ." then "gzip -d config.gz" which should leave you with a file called "config", then "mv config .config"
Now here's where I run into a problem..when I do "make xconfig" I get this...
Tried to install the qt3-devel packages from CD but guess what? I ran into cdrom errors which is what I was trying to fix in the first **** place...catch 22 eh?

I'm installing CentOS for the first time to run mythtv on (I previously used Fedora, but the new version cycle was too quick). As part of the instructions I'm using, I am told to run system-config-boot (to ensure that centosplus kernel is loaded on boot). The problem is, I cant find this option in my installation of CentOS. Another option I have is to manually edit the grub.conf file, but I'm not sure exactly how I should edit it.

I am a long time Unix system admin and this one has got me stumped.When I try to run the system-config-network (or any of the system-config-xxx programs) from the links on the GNOME interface, I get a message pop-up that says, "Unknown error" and no additional information. I have also opened a terminal and run it from the command line (/usr/bin/system-network-config) and I get the same "Unknown error" pop-up. I was not the one who originally configured this server, so I am not sure of the history or how it might have been broken. I can't seem to find any debugging information or even any command line parameters that might give me a clue what the complaint is. There is no error number or any other helpful hint as to the cause of the problem.
I have been manually editing the config files so the server is up and running but it is tedious to manage the server without the GUI.Has anyone seen this before? I assume it is a configuration issue, but I am not sure where to look.uname -aLinux xxxxserver 2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux/etc/redhat-releaseCentOS release 5.4 (Final)

I want to add my printer to ubuntu 10.04. When I run the system-config-printer (System->Administration->Printing) I can't choose the "Add" in the menu bar (ctrl+n does not work either).

I'm trying to run extract-ikconfig because I've mistakenly deleted an old kernel config that I'd like to recover. However, when running the script from the latest (2.6.32.5) tree I run into this error:
Quote:
ERROR: Unable to extract kernel configuration information.
This kernel image may not have the config info.
Coincidentally, this happens with all of my kernel images. Is it a fixable problem? I should really set CONFIG_IKCONFIG_PROC next time..

I've been trying to run the vmware-config.pl, but I'm getting this message
Quote:
None of the pre-built vmmon modules for VMware Server is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)? yes
Then I hit enter, and later get this message
Quote:
Unable to build the vmmon module.
I have installed gcc and the kernel-devel tools, and after installing all that I did an update, but still not getting through with the configuration.

I just done a brand new install of fed12 and did all the yum updates. Apache seems to start ok and I always liked the http config tool but it won't run on Fedora 12. I downloaded and installed system-config-httpd.noarch 5:1.4.6-1.fc12 and it all went fine but when I try to start it I get the usual box asking for my root password, I type it in and press enter, the box disappears and then....nothing. If I run system-config-httpd in a terminal I get the same box asking for root passowrd but when I enter it I get a long scroll of text which ends with:
line 4: 2137 Aborted (core dumped) /usr/bin/python /usr/share/system-config-httpd/ApacheConf.py
I don't know what causes this. Is there any way to get the http config tool working?

I'm experimenting with 2.6.33-ck1 mainly because I want to try the BFS. I successfully configured and installed the patched kernel, but I'm experiencing various problems on the desktop. The biggest is Chromium not working at all, but there are several others, including graphical glitches in firefox. I'm sure I left some important module off or made a mistake for some settings My question is that is there a 2.6.33-fc12 kernel yet, and does it have a .config available? I'd like to load those settings in menuconfig and use them as a starting point to properly configure and complie a -ck patched kernel.

have a sample kernel .config, so I can compile a small custom kernel on my vps? I tried to make it alone,but I removed stuff,so that my VPS won't start anymore. Virtualization is KVM, running on a Core 2 Duo.

I would like to compile my own kernel. I am familiar with how to do it and have done it in the past so I'm not looking for a how to compile a kernel. In the kernel config are many, many options. In the past when I compiled kernels I always wondered about what is needed and used. What is the best way to determine what is currently used, not set or enabled in the existing config, but actually used by my existing kernel?I have a general idea of what is loaded and could do trial and error, turn this and that off, recompile, etc but is there an easier way?

I am using FC15.I need a kernel with a different configuration - with the "Preemptible Kernel (Low-Latency Desktop)" option in the Processor Type and features menu. I need this to support my firewire audio device. I would like to build a new kernel RPM from the SRPM so that i can keep a clean system with RPMs for all files, and I don't really want to manually override the kernel bypassing RPM.I am following **exactly** the process described there - I install the SRPM, unpack the source, then use the starting sample config files in the BUILD folder to create a new customised .config file with the new option, then copy this back to the SOURCE folder.
This works perfectly if I make a standard kernel. But I cannot get the process to work if I change the config file. Every time I compile I end up with exactly the standard kernel -- a vanilla i686 kernel, without my custom config.I believe the problem is that when I run rpmbuild to compile the kernel, this process overwrites my config option. I found that there is a script (merge.pl) which creates new config files dyanmically for all kernel options based on fragments in the SOURCE folder. It looks like the script never uses the config file that I am putting into the SOURCE folder.The wiki page suggests using this command to copy my custom config file cp .config ~/rpmbuild/SOURCES/config-`uname -m`

Anyone can tell me how to enable and config auditd in linux kernel 2.6.9-5.EL. I have only found command auditd and auditctl in server that run kernel 2.6.9-5.EL. I ran auditd & and can saw auditd ran in my server. But I couldn't do anything with auditctl, no status, no rules, nothing :| . I tried to find audit.rules or auditd.conf but that nothing I can find.

This is my first effort in making something more appropriate for laptop users (exclusively). This is a kernel config for 2.6.30.5. I started with the Slackware Generic-SMP 32bit kernel config (this is a 32bit kernel config). All credit for (in my opinion) the best starting place for any kernel config goes to Patrick Vokerding. (Please tell me if I am or am not doing this properly in terms of respecting the work of others, GPL, GNU, etc.)

Can I use the config for my current kernel (the jessie 3.16 one), and use it to build a more recent kernel (3.18)? Do I just copy across the config and try and build with it, or is there some tool that will bring across the existing config but also set up reasonable defaults for any new options in the newer kernel, and any other migrations that might need to be applied?

I'm recompiling my kernel on a dell latitude c600 running lenny as I type, and it's taking forever, so far upward of 4 hours.I think I'm getting drivers for ever piece of computing hardware since the univac So I googled "a kernel conf creator" and got [URL]... Its a nice, clean method for finding what hardware your using... you just run lspci cpuinfo make xconfig and put in all the info yourself. So I was thinking: this is exactly the kind of dull, repetitive behavior that computers were made for. Is there a program that can find my hardware info, and make the.config itself, with very little user input?Or should I reinstall debian on another partition and steal the .config from it? Or should I man it up and do it myself?

I want to start to play with "homemade" kernels. (To get some experiences in this subject). I want to do this step-by-step. I have already read a lot about this. I have a Fedora 10 running. So I want to start with this. I have read that there is a "special" way to create a kernel for Fedora. [URL] OK. I understand this +/-. When you build a new kernel with an other version number, you have to rebuild all the modules with this new kernelversion, and you have to install these also.
But : I want to start with modify only some parameters in my kernel config. Do I need to rebuild and re-install the modules also? Will it not be enough to rebuild only the kernel? (vmlinuz) Where can I find some information about the options I can disable in my kernel to speedup my system? (boot process ed). I want to suppress the loading of unneeded modules. I want to understand the options in menuconfig (and there are a lot of options ! ! )

Supposed I have built customized kernel rpm four times in a row and the latest built kernel failed. If I still have all four kernel.xxx.rpm files, is there any way that I could get back the .config file used for each of those four builds? I really could not recall exactly what changes I had made in .config for each build.

How do I discover which kernel config parameters are important for my laptop hardware and frequently used applications? I'm not looking for something that is 100(...)% optimized for my hardware. I would prefer to have modules for everything that I don't use at all or often. I would prefer to avoid modules (built-in) for things that I use all the time but then any updates might mean a kernel rebuild. I'm currently running the generic PAE edition of the repository kernel. I think that I'm running the 32-bit flavor at that.
Code: user@host:path$ uname -a Linux mumbles 2.6.31-19-generic-pae #56-Ubuntu SMP Thu Jan 28 02:29:51 UTC 2010 i686 GNU/Linux I know the following from sysinfo

I'm looking for the .config file for the kernel which ubuntu uses to compile the standard generic kernel which is delivered in compiled form. I downloaded the following kernel archive ( 2.6.31.8 ): [URL]... I need the original file, because I'm not able to configure a working kernel, so I want to try to compile the kernel with the standard configuration. Afterwards I'm going to change some options.

I was just wondering if using a non-smp kernel would be ok on a older p4 system with no x. I am wondering due to some functionality in IPTABLES that is broken in the SMP kernels ( -m owner --sid.pid,cmd-owner).
Could someone that is running a NON-SMP kernel advise as to whether the support for -m owner --cmd-owner is working in iptables with those kernels? Also, could someone advise me if running a NON-SMP kernel is even advisable? The machine will not have x.

I am using Angstrom Linux on a Beagleboard and it does not have CONFIG_HIDDEV enabled. How do I enable that config setting and rebuild the Kernel? I can build the Kernel as it stands using Bitbake, but the config file containing the CONFIG_HIDDEV=n is commented as "auto built, do not edit". Can I ignore that and edit it? Or is there some other way to control the "auto building" of it?

Anyone able to compile kernel 2.6.38.6 on Slackware 13.37 successfully using the config from testing/2.6.38.4? I was able to get .4 and .5 to compile successfully, but with .6 I get the following after running "make modules".
Code:
WARNING: modpost: Found 11 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
Running "make CONFIG_DEBUG_SECTION_MISMATCH=y 2>&1 > outfile" gives me a bunch of WARNINGS as follows:
Code:
WARNING: vmlinux.o(.text+0xe656a): Section mismatch in reference from the function build_all_zonelists() to the function .meminit.text:setup_zone_pageset.clone.56()
The function build_all_zonelists() references
the function __meminit setup_zone_pageset.clone.56().
This is often because build_all_zonelists lacks a __meminit
annotation or the annotation of setup_zone_pageset.clone.56 is wrong.....
WARNING: drivers/watchdog/nv_tco.o(.devinit.text+0x14): Section mismatch in reference from the function nv_tco_init() to the function .init.text:nv_tco_getdevice()
The function __devinit nv_tco_init() references
a function __init nv_tco_getdevice().
If nv_tco_getdevice is only used by nv_tco_init then
annotate nv_tco_getdevice with a matching annotation.

My machine is a new Fedora Core 12 install. The install did not make an /etc/x11/xorg.conf file by default, which is odd. So, I want to change things with the display. But there's no "system-config-display" in /usr/bin. What's going on? Why wasn't this installed by default? I've had lots of other problems with X on this machine as well:
the 10x20 fonts were missing XFree86-Misc error messages whenever I start an xterm I also receive these warnings, intermittantly, when I create xterms:
Code:
Xlib: extension "XFree86-Misc" missing on display ":0.0".
xmodmap: please release the following keys within 2 seconds:
Control_L (keysym 0xffe3, keycode 37)
xmodmap: please release the following keys within 4 seconds:
Control_L (keysym 0xffe3, keycode 37)
xmodmap: please release the following keys within 8 seconds:
Control_L (keysym 0xffe3, keycode 37)
With this many problems I want to know if there's something in general broken with X on FC12, or was that just my install, or what?
