I just want to upgrade my Slackware 13.1 kernel (18.104.22.168) to the latest stable kernel from kernel.org (22.214.171.124). I have never done anything like this and I am a Linux newbie, so I would appreciate a "Kernel Patching for Dummies" version if possible. I did do a search on this forum and most of what I read was over my head. I found an FAQ on kernelnewbies.org on "How To Apply A Patch" but when I attempted what they suggested, it said it couldn't find the file to patch at line 5 and asked me which file to patch. So I CTRL-Z'd out of there and came here. Here's what I tried:
IMO it really is the big thing! The patch being talked about is designed to automatically create task groups per TTY in an effort to improve the desktop interactivity under system strain. Mike Galbraith wrote the patch, which is currently in its third version in recent weeks, after Linus Torvalds inspired this idea. In its third form, this patch only adds 224 lines of code to the kernel's scheduler while stripping away nine lines of code, thus only 233 lines of code are in play. Tests done by Mike show the maximum latency dropping by over ten times and the average latency of the desktop by about 60 times.
I am trying to compile the iscsi-target software SCST. It wants me to apply a patch to my Linux kernel in order to allow for certain performance gains. The problem is I still new to Linux development. Where do I begin? How do I apply the patch? Do I need to recompile the kernel? I am running Ubuntu 10.04.3 amd64
there is an issue with the way the Linux Kernel addresses memory by default and the graphic drivers for my Asus G1Sn. I have a patch that I had compiled against a custom kernel for 2.6.27.xx how ever it does not work with the latest kernel in Fedora 11. It is beyond me to rewrite the patch to work with a different kernel.
Ok here's the problem : I tried to patch the kernel of my Debian server with GrSecurity but when I rebooted I couldn't SSH the server anymore, but my host has a rescue system that lets me SSH the server so I can fix things.
So maybe the kernel patching failed, maybe it's a only a problem with Grub.
I don't really know what to do to fix this. If I messed up the kernel what can I do ? Can I just fix the problem by modifying the grub entries to only boot on the old kernel (I don't even know if it's here anymore, I'm quite the n00b) ?
Well for now I'll just try to mount the partitions (won't let me do "mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab" )
edit : to be clearer my main question is : how can I determine if it's because the kernel is messed up or because the system wouldn't boot properly ?
edit 2 : is there a way to create a log of what happens at boot so I can have an idea about what's wrong ?
I'm having problems to install SCST in Fedora 11.I'm not able to apply the kernel patch because there isn't a file called drivers/scsi/scsi_lib.c in the /usr/src/kernels/126.96.36.199-167.fc11.i868.PAE.Does anybody have an idea on how to proceed?
I have got a Ubuntu 11.04 (Codename natty) Kernel Version : 2.6.38-8-generic-pae. I want enable PoPToP PPTP + MPPE 128bit Encryption + MPPC Compression VPN Server on that. I am looking for patch for MPPE/MPPC support of the kernel 2.6.38-8 (Ubuntu 11.04 natty)
When a real kernel version is upgraded, like say 2.6.32 to 2.6.38, the old kernel is left intact and is ready to be used in case of a problem with a new one, but when only a debian patch version is updated, like 2.6.32-30 to 2.6.32-35, the old kernel is replaced with a new one. More then this, aptitude shows that older version is not in repository either, so how do you supposed to revert back? Well, i did found -30 in apt cache when i got hit by a nasty regression in -35 yesterday, but what if i had cleaned apt cache?
I did the latest patch/update to lucid this morning and it would appear that my Volume control has gone missing from the task bar. There doesn't seem to be a volume control in Applications > Sounds & Video either. I am sure this has to do with the patch upgrade that I installed as everything was working fine before. For that matter, I had no system sounds either and it took a power off reboot for that to come back. My Music program (atunes) is not working properly either and keeps locking up. How do I reverse this patch or get my system back to a functional state?
[URL]... Anyone got this going on slackware? I've a single cpu and twincore here and the videos of the original patch were impressive. I tried it and I don't have /sys/fs/cgroup anything. So I added the cgroup scheduler in 2.6.35, but no dice. Do I have to go to git or 2.6.37??
I;m installing RTAI and I get this message. I can't seem to find the solution, because I really don't know exactly what the main problem is. There are a list of error,s and warnings that I 'm not sure from where should I tackle the problem: Here is what I get when I boot my 188.8.131.52 kernel with GRUB. (I used the RTAI x86 compatible patch):
I'm trying to make a 184.108.40.206 kernel using kernelcheck. I have custom compiled two previous kernels for maverick alone, so my .config it will load is optimized as I built with the localmodconfig option, and I have been using the 200 lines patch on my 2.6.35 kernels. I want to find the patch file that works on the 2.6.37 kernel for the 200 lines patch so I can optimize my speed, but the patch i found galbraith-patch is only for 2.6.36.
This morning I ran the automatic upgrade provided on the repositories, updating my kernel from 2.6.38-8 to 2.6.38-10.Unfortunately, upon reboot I discovered that a series of patches I'd applied in order to get my wireless card on my desktop working had been undone (see I had to run a modified version of the instruction set in order to get my wireless back on.My question: is there a way to trigger this every time the kernel upgrades? I'd hate to have to run this cumbersome set of commands manually every time.
I am trying to compile a patch for HDMI audio, reference this thread [URL]
Code: Instructions: - download alsa-driver-1.0.21 from alsa homepage - unpack downloaded alsa: $ tar jxvf alsa-driver-1.0.21.tar.bz2
- download and apply my patch $ wget http: [URL] $ cd alsa-driver-1.0.21 $ patch -p 1 < ../alsa-driver-1.0.21-nvidia-ion2-hdmi.patch
- compile alsa $ ./configure $ make $ make install when I do ./configure it outputs this
Code: The file /lib/modules/220.127.116.11-pclos6.bfs/source/include/linux/autoconf.h does not exist. Please install the package with full kernel sources for your distribution or use --with-kernel=dir option to specify another directory with kernel sources (default is /lib/modules/18.104.22.168-pclos6.bfs/source). How can I direct it to install with the 'full kernel sources' ?
For those that haven't heard, Ksplice is an easy to install program that allows you to do critical updates without ever having to reboot. Yes, this includes updates to the kernel.It's free for Ubuntu 10.04 LTS and Fedora 13 (desktop, not enterprise) OS. I tried to install it on 10.10 beta but said it doesn't do beta versions.I just wanted to find out what people think of this. I think this is an awesome idea and if it works well, perhaps it could be implemented in future versions of Ubuntu?
The server runs# uname -r2.6.18-128.4.1.el5However, today I executed yum update kernel*due to security advisory. I was just about to reboot the system when I realized that it runs VMWare Server Instance that will most likely fail to restart after kernel upgrade (I had a hard time fixing it after previous kernel update). Now I want to keep 2.6.18-128.4.1.el5 after reboot.I see that new kernel is scheduled for booting:
stuff about a kernel speed up patch? Here is one Article The Linux desktop may soon be a lot faster - Computerworld Blogs And Yet another even stranger kernel speed up here:
Alternative To The "200 Lines Kernel Patch That Does Wonders" Which You Can Use Right Away ~ Web Upd8: Ubuntu / Linux blog I have no idea if any of this stuff is true, but lets see some of our high power guys check it out and let us know what is true or not.
