Kernel26 , Kernel26ck , or Kernel26beyond ?

Howdy- I have been an arch user for years now and I have always run the vanilla kernel. I recently saw a post on kerneltrap (via lXer) about the CK patch set. So ... I've seen CK and Beyond in the kernel list for quite awhile.
My question: Is it worth it to migrate to CK or Beyond for a performance increase? I usually only use my computer for web development (rails) , random pet project development, web browsing, and audio/video. What I would primarily look for is increased load time for my applications and more responsive Gnome.
Btw- the only performance work I have done is to make sure I am running light on services and use prelink ... anything else I could check out?

Con Kolivas has not written a 'brand new' CPU scheduler . His scheduler has been around for quite some time. Ingo Molnar has written a new scheduler, borrowing some of Con's ideas .

will be possible add the fbsplash path to ck?
If you want 'optimal' performance there's no hassle in building your own kernel. Just strip out the kernel PKGBUILD (any will do as a starting point). And put in the patches you want yourself. It's an excellent occasion to take a close look to C too .
I build my own kernel using ck, reiser4, and some custom patches (amongst which grsecurity for my server install). The hard work goes in the PKGBUILD, but once that's done, it's just rearranging patches, updating checksums in the script, checking the config if you need to change anything, and off you go .

Why not 'uname -r' in externl modules PKGBUILD?

I am in doubt about the correct AUR policy for PKGBUILD of external kernel modules: in the PKGBUILD and in the install file, one has often to refer to the kernel against which the module should be compiled. The best way to do this seems to me to use a 'uname -r', so that the actually running kernel is matched. This is what I have done in a couple of PKGBUILD I contributed.
However I see in the ABS tree and in other PKGBUILDs in the AUR that they often hardcode the reference to the default arch kernel. Is there a reason for this choice? A disadvantage seems clear: the user willing to compile that module on a non-default kernel is called to modify the PKGBUILD. Is there also an advantage? Should I revise my PKGBUILDs according to this prevailing stance?

Common practice, as you have seen, is to create a variable called _kernver, and use that in the build. The principal reason for this is to allow modules to be built for any installed kernel, whether it is running or not. Using `uname -r` only builds the module for the running kernel. The default value for _kernver is the current stock kernel, as the majority of users will be using it.
A practical example - I have kernel26, kernel26ck, and a customised beyond kernel on this machine. If I decide to install a new external module, I can do three builds, one for each kernel, without rebooting, and regardless of which kernel I'm actually using. If I was using `uname -r`, I would have to reboot into each kernel to complete the builds.

Error on boot with kernel26 and kernel26beyond 2.6.19

i get this right after "Loading Udev Events", it hangs for about 4 minutes then continues to boot just fine. blacklisting snd_hda_intel and snd_hda_codec fixes the problem any ideas? the audio device is "Intel Corporation 8281G (ICH7 Family) High Definition Audio Controller (rev 02)"

To find out what happened during the installation, boot from the software 1of2 cd, to single user mode, with the following command:
boot cdrom -s
The system will bootup to a # prompt. fsck the root filesystem, and mount it to /a, with something like the following:
fsck /dev/rdsk/c0t0d0s0
mount /dev/dsk/c0t0d0s0 /a
If /var is a separate partition, you will have to fsck/mount it too:
fsck /dev/rdsk/c0t0d0s3
mount /dev/dsk/c0t0d0s3 /a/var
The installation log will be in /a/var/sadm/install/logs/install_log. This file should have information about what happened during the installation.

Any chance to see the linux-vserver patch included in kernel26 ?

Hi,
Is there any chance to see the vserver patch is included in the kernel26 or kernel26ck some day ?
I often use it (am I the only one ?) and I'd love to be able to use it out of the archlinux box.
Thx and congrats for the work.

Sorry, I can get into more details :
Lazily quoting the http://linux-vserver.org web site :
"Linux-VServer provides virtualization for GNU/Linux systems. This is accomplished by kernel level isolation".
The main advantage over Qemu, Virtualbox or Vmware, is that there is only a very little performance loss for the virtual hosts. Virtual hosts, which all are linux hosts are isolated from eachother, no hardware emulation is done. You can see it like a kind of "super chroot/jail".
Basically, this is composed of two parts : a kernel patch, ans some userland utilities. The kernel patch (http://ftp.linux-vserver.org/pub/kernel … 0-rc3.diff) applies easily against a vanila kernel. The linux-vserver guys follow very well the kernel updates and I've been applying the patches for several versions now, without problem.
Userland apps have already been ported for Archlinux (http://oldwiki.linux-vserver.org/ArchVserver), even if they look a little outdated and can't be found on the archlinux.org package search engine.
The only hitch is the need to build a home-maid kernel.
I thought this patch inclusion could be of someone else's interest.
What is Archlinux kernel patch admittance process ?
Do you provide only vanila kernels ?

Kernel26-beyond + ndiswrapper + wpa_supplicant [solved]

Hello!
A few problems with kernel-2.6.16-beyond and my network profile (ndiswrapper plus wpa2-psk).
Here we go:
- Running Arch 0.7.2, uptodate with current and extra repos.
- Installed kernel26beyond package and ndiswrapper-beyond.
kernel26beyond version: 2.6.16.beyond4.1-1
Ndiswrapper-beyond version: 1.16-1
- Edited the grub configuration, adding the new kernel:
title Arch Linux Beyond
root (hd0,1)
kernel /vmlinuz26beyond root=/dev/hda5 ro video=vesafb:ywrap,1280x800-16@60
initrd /initramfs-beyond.img
- Reboot to test the new kernel.
It seems the wifi profile doesn't start. Ok, let's see...
My wifi profile works OK with stock Arch kernel, but after the installation of kernel26 beyond the wpa socket directory (/var/run/wpa_supplicant) has dissapeared.
No problem, created it again and restart the network. Still no luck.
ndiswrapper-beyond seems to work fine:
$ ndiswrapper -l
bcmwl5 driver installed, hardware present
dmesg output:
ndiswrapper version 1.16 loaded (preempt=yes,smp=yes)
ndiswrapper: driver bcmwl5 (Broadcom,05/26/2005, 3.120.27.0) loaded
ACPI: PCI Interrupt 0000:06:02.0[A] -> GSI 21 (level, low) -> IRQ 22
ndiswrapper: using irq 22
wlan0: vendor: ''
wlan0: ndiswrapper ethernet device 00:14:a5:4e:11:27 using driver bcmwl5, 14E4:4319.5.conf
wlan0: encryption modes supported: WEP; TKIP with WPA, WPA2, WPA2PSK; AES/CCMP with WPA, WPA2, WPA2PSK
The wpa_supplicant configuration works fine with stock kernel:
$ cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
ssid="myssid"
proto=RSN
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
#psk="blah"
psk=encrypted blah
I have tried adding ndiswrapper to the modules array in /etc/rc.conf, the network doesn't start.
Later I have changed the file /etc/mkinitramfs.conf and generated a new initramfs-beyond.img, trying to enable ndiswrapper here and/or USB subsystem support, but the result was the same.
The *ONLY* solution I have found is booting the system with the beyond kernel, wait to the network init script to fail (it seems a dhcp timeout), log into the system and execute the following:
# killall wpa_supplicant
# /etc/rc.d/network restart
Any idea about why I have to kill wpa_supplicant to get the wifi working with it? As I said, this problem does't exist with the stock kernel, and I don't see any errors reported by wpa_supplicant.
Thanks in advance!

miausX

Thanks for your reply, Phrodo_00.
I think it is using the correct ndiswrapper module (beyond).
Looking at the modinfo output:
$ modinfo ndiswrapper
filename: /lib/modules/2.6.16-beyond/misc/ndiswrapper.ko
license: GPL
version: 1.16
description: NDIS wrapper driver
Maybe this problem is related to the execution order of the commands (modprobe ndiswrapper, wpa_supplicant, dhcpcd) during boot.
Everything works fine after killing wpa_supplicant and restarting the network, the ndiswrapper module is loaded, wpa_suplicant is running as a daemon, etc.
$ ps -ef | grep wpa
root 4262 1 0 10:12 ? 00:00:00 wpa_supplicant -wB -i wlan0 -c /etc/wpa_supplicant.conf -D wext
$ ps -ef | grep dhcp
root 4274 1 0 10:12 ? 00:00:00 dhcpcd -t 30 -h portatil wlan0
$ lsmod | grep ndis

System doesn't boot kernel26beyond

Since a week or so, my system doesn't boot, unless I press <enter> and the power button a few times during the process.
Once it has booted, everything works fine, but it is highly annoying nevertheless.
it seems to have something to do with loading my hardware.
Boot freezes after these log messages:

I am using mkinitcpio already: /boot/grub/menu.lst:
# (0) Arch Linux
title Arch Linux
root (hd0,2)
kernel /vmlinuz26beyond root=/dev/hda4 ro
initrd /kernel26beyond.img
my /etc/mkinitcpio.conf:
MODULES=""
BINARIES=""
FILES=""
HOOKS="base udev autodetect ide filesystems"
I tried removing scsi and sata, since my root is on an ide disk. But the problem persists.
also recreating an image using mkinitcpio or reinstalling the kernel26beyond package using pacman doesn't help.
Does anyone have any idea what might be wrong and how this problem might be resolved.
It seems like a trivial issue since the systems basically works fine otherwise. However, I can't figure it out by myself, I have tried for a week.
Any help would be greatly appreciated.

I'm not sure if this will help you, but I suddenly was having a lot of trouble booting. My system would just freeze with a blinking cursor. I thought it had something to do with my floppy drive because if I changed the boot priority in my bios to boot from the hard disk 1st, the system would boot but would hang for a very long time in areas, and as long as 5 minutes loading uevents. I suspected this was a udev problem.
I issued a few commands to reset udev, thinking maybe recent updates didn't take effect, which did the trick...
# udevtrigger
# udevcontrol reload_rules
After that, everything is back to normal. I'm still learning about udev and I'm still fuzzy about a lot of the techy stuff.

Pacman says i need kernel26-2.6.13.4-3 even tho i have .....

Ok so i did today my daily pacman -Syu and with some other packages that it says i need to update also is listed kernel26-2.6.13.4-3 even tho im running arch with kernel26-scsi-2.6.13.4-3 , i have no idea why this his happening but something tells me it isnt rite and if i update to that package my system will get bad .
So i my guessing is this needs to be reviewed maybe somo bad dependency or some like that
Cheers

Ok so i started updating package by package until i got to the mono-debugger wich is the package that is asking for the kernel26, maybe this will help more to see the problem. dependency check on mono-debugger ??

I installed mono-debugger omiting dependency check and also monodevelop and now im fine, pacman doenst ask anymore for the kernel update.

I think it's more likely that kernel26-scsi should have

in its PKGBUILD, which it does not at present.
Regardless, no packages should depend on the kernel. That's part of the design (at least according to Xentac).

[Solved] Massive bootproblems with kernel26 2.6.38

I don't know what's wrong with my computer, so I post it here:
Every kernel before 2.6.39 worked fine with 'irqpoll' as kernel parameter.
'Irqpoll' is needed, otherwise the boot hangs somewhere and I have to press Enter several times to continue.
The problem is now: current kernels refuse to boot, I just get a blinking monitor or errormessages.
I've read that 2.6.39 got a different IRQ handling, maybe that is the 'problem'.
Bios version in the latest, I tried everything. Disabled HPET, changed Bios IRQ settings, kernel parameter (irqpoll irqfixup noacpi noapic nolapic erst_disable hest_disable) ...
acpi=off is the only option which works fine.
Today I fixed my DSDT (produces 0 error and warnings now) and compiled it into kernel26-mainline (3.0-rc3) -> same problem.

I've found out that disabling C1E in the Bios helps.
After searching the forum I read this solution again -> https://bbs.archlinux.org/viewtopic.php?id=92801
'irqpoll' is also no more necessary.

Upgrade kernel26-firmware to linux-firmware report with some problem

Just now I upgrade my system from kernel26-firmware to linux-firmware, in X (Awesome WM).
After press Y and pacman start downloading, I'm afk for a while (take a bath), when I'm come back
My system freeze and proses show that system still make mkinitcpio for fallback.
I hard reset, and boot. Boot failed in 10 seconds message because it can't detect my filesystem.
Follow suggestion that I need add some parameters I can boot.
Then I check with pacman -Syu, and you can guess there's still db.lck. Then I remove it, and invoke pacman -Syu again, pacman failed because there's already file from linux-firmware on disk.
I try to downgrade, but failed with the same reason. Then I remove all folder and file that conflict, and install kernel26-firmware then upgrade to linux-firmware, now I have linux-firmware on my system.
Learn a lot from that problem, any thought guys ?! Maybe some of you have a better way to solve something like that ?!
regards,
igndenok
Edit:
After I read pacman man, there's a force option (-f). Can I used that just in case (maybe) I have the same problem again ?

All I can say is that when the linux-firmware package got into [testing], I switched without problems on my laptop. I 'migrated' to the linux-firmware package on my server a few hours ago and it went smoothly too. I don't really think your problem has anything to do with the firmware package, since that doesn't trigger an initcpio rebuild, nor are there any file conflicts between both firmware packages.

[solved] Errors in ugrading to kernel26-2.6.38.5-1, Opera involved?

While upgrading kernel to kernel26-2.6.38.5-1 i get some error messages and some Opera related output.
Opera related output is like this:

This is the second machine that i try to upgrade and the first machine had similar output and does not want to boot anymore
What should i do to get kernel to upgrade without errors?
Last edited by mjones (2011-05-09 03:58:07)

I had the Opera binaries untarred to a folder in my path and it seems that somehow Opera interfered with the kernel upgrade. Temporarily renamed the Opera folder (thereby removing it from the path) and kernel upgrade succeeded flawlessly. Case closed

No modules found in kernel26 package compiled via ABS

Hi,
I have been experiencing problems building kernels recently. I've used ABS and AUR pkgbuilds to build kernels since 2.6.30, mostly to enable the proper USB scheduler for my hub and to try outside kernel patches, see kernel26-ck. However, since the release of 2.6.35.2, more likely a mere coincidence, I've been compiling small kernels (~4MB) from the default .configs without any modifcations to the PKGBUILDs or the config files. Looking at the compiled packages, I noticed the omission of the kernel modules that are normally located in /lib/modules/[kernelname]/kernel. The missing kernel modules obviously causes my machine to be unable to boot (https://bbs.archlinux.org/viewtopic.php … 15#p872215). My makepkg.conf is below. Any explanation on what is going on? Thanks

Ran linpack and noticed that my CPU temp peaked at 74C, well below the critical threshold of 100C (according to intel). Usually, my CPU runs at arounr 48-55C unless I am doing some CPU-intensive task. When that happens, it will run up to the upper 70s.

[FIXED] kernel26-lts for Intel driver's conflict with KMS in kernel26

Hi,
I am running on a GM965/GL960 Intel video card. During the install (and later use) of Arch, I had to add i915.modeset=0 on the kernel line in grub when booting to get to a visible terminal; otherwise I used to get a blank screen after udev loaded. However, taking a leaf from Ubuntu on same laptop (and since most fixes for this issue recommended downgrading the kernel), I installed kernel26-lts. This works quite well with the latest xorg (1.9) and intel driver (2.12.0-3).
kernel26 - 2.6.35
kernel26-lts - 2.6.32-23
1. Are desktop users recommended to use the LTS kernel?
2. For certain components (Broadcom wi-fi), where I intend to install drivers from the AUR - will they work on LTS kernel?
3. Is this a good strategy? I intend to keep kernel26 also on my machine and when the Intel issue gets fixed, I will switch back to kernel26.

1. If it works for you, use it.
2. There are -lts versions of some packages and compiling others against any supported kernel should be fine.
3. Seems nice and simple.
You can also try .34 version or the regular kernel.

[SOLVED] kernel26-selinux "ugly" release string

I am maintainer of kernel26-selinux in AUR. Recently I noticed that built kernel sais (uname -r) 2.6.35-selinux-gd4918f4-dirty instead just 2.6.35-selinux, which I would expect. I found option CONFIG_LOCALVERSION_AUTO which I think should solve it if set to no, but in that case the release string is actualy 2.6.35-selinux+ (note the plus symbol).
Would someone kindly tell me, what to change, so that uname -r would show just 2.6.35-selinux? Or give some arguments why the other way is better, in case it is?
PS Here is link for up-to-date tarball, as AUR doesn't yet support splitpackages: http://profi.edisk.cz/stahnout-soubor/1 … 1.9KB.html
PPS I am quite new to building kernel stuff, so please speak slowly to me.

Well the sed line used in kernel26-ice is in fact wrong.

there should be:
sed -i 's/head=$(git rev-parse --verify --short HEAD 2>\/dev\/null)/0/' \
${srcdir}/linux-${_basekernel}/scripts/setlocalversion
as the former deletes contents of whole file.
EDIT:
And the contents of the if to be changed by the sed did changed too. So hopefully last modification of the hack is:
sed -i -e "s/head=\`git rev-parse --verify --short HEAD 2>\/dev\/null\`/0/" \

Yes, if you read the comments I commented that I'd already fixed that, but in git. The maintainer just hasn't gotten around to updating my fix to the AUR PKGBUILD.

Then there's of course the config, it's based on kernel26 at the moment,.
I'm building it now, to test. I had to install icc manually because the AUR package for icc didn't work for me. I had to install icc manually (run the installer), but that wasn't enough. Before makepkg, you have to add the icc to $PATH e.g.
PATH=$PATH:/opt/intel/Compiler/11.1/064/bin/intel64
and execute iccvars_intel64.sh which is in that folder.

icc kernel compiles in similar time as gcc kernel, or if there any differences these may be negligible. To be honest I was not really interested in compiling times (was doing somethig else as it takes ~12 min on my system to finish kernel compilation), but rather with overall kernel performance. This is not the same as OS performance, but I am planning to compile firefox with icc and maybe some other stuff (if I am bored enough).
If you have 32-bit OS (I have no idea how it will work on 64-bit), try it. I can't post PKGBUILD for 32-bit icc kernel because I don't use PKGBUILD for kernels or nvidia as I have found it limiting/cumbersome/unnecessary (while PKGBUILDs work great for anything else on Arch).
The only part really annoying is intel server speed. Downloading icc sources (710MB for 32-bit only) tahes two hours. If you try to get 32/64bit sources even longer (1GB download).
32-bit icc PKGBUILD package requires only one modification related to Release Notes otherwise makepkg will fail. Once installed export icc path, edit kernel Makefile and change one line related to compiler: change gcc to icc. You can also add some compiling optimizations.
Pretty easy if you did compile kernel before.
note added:
actually combination of icc and zen seems to have nice effect on desktop responsiveness (this is 2.6.33)

Two problems with kernel26-2.6.39.1-1

hi,
I just upgraded system, and i found two problems with kernel26-2.6.39.1-1
first one is that i cannot use "reboot", the screen was black.
second, i cannot use " openconnect" to connect the vpn. and the error is
CSTP connected. DPD 30, Keepalive 20
Error: either "to" is duplicate, or "ipid" is a garbage.
Connected tun0 as XXX.XXX.XXX.XXX, using SSL
Continuing in background; pid 1661
DTLS handshake failed: 2
after i downgraded the kernel to kernel26-2.6.38.8-1, both problems were solved. so, i think, there should be something wrong with kernel26-2.6.39.1-1

thanks for replies.
" poweroff" was ok. but "reboot" didnt work (kernel26-2.6.39.1-1).
after i run "reboot",
the xorg was first killed,
then some words showed on the screen line by line,
finally, as far as i remenber, it stopped at "waiting for XXXXXX" or "XXXXXsignalXXXX".
im sorry i forget the exact words. but i think they are the last words we can see if we run "reboot"

Kernel26 , Kernel26ck , or Kernel26beyond ?
