hey guys i have local/kernel26-pf-k8 2.6.38-pf2 and i am unable to make virtualbox module any fix

JokerBoy · 2011-03-29 23:51:39

you need the headers too.

The headers are included. See previous explanatory post.

cd /lib/modules/2.6.38-pf ; sudo rm -f build ; sudo ln -s /usr/src/linux-2.6.38-pf build

Or update to 2.6.38-pf2.

Ok, I installed kernel26-pf-core2 from the dropbox repo, and rebooted. Somehow I think I'm still on the arch kernel.. Anything I have to change in menu.lst etc to boot into the pfkernel?

You need to tell grub to boot vmlinuz26-pf. Edit /boot/grub/menu.lst as root, duplicate the (0) and (1) entries of the stock arch kernel and append -pf to vmlinuz26 and kernel26. The -pf entry should be the very first. My menu.lst looks as follows (the resume= option is optional, tuxonice scans all swap partitions for hibernation images):

title  Arch Linux PF
root   (hd0,4)
kernel /boot/vmlinuz26-pf root=/dev/disk/by-label/ROOT ro vga=773 resume=swap:/dev/sda6
initrd /boot/kernel26-pf.img

title  Arch Linux PF Fallback
root   (hd0,4)
kernel /boot/vmlinuz26-pf root=/dev/disk/by-label/ROOT ro vga=773 resume=swap:/dev/sda6
initrd /boot/kernel26-pf-fallback.img

# (0) Arch Linux
title  Arch Linux
root   (hd0,4)
kernel /boot/vmlinuz26 root=/dev/disk/by-label/ROOT ro vga=773
initrd /boot/kernel26.img

# (1) Arch Linux

^^ Thought so! Thanks! Sorry for being a noob

graysky · 2011-04-18 09:08:48

@kalpik - FYI, use the following to see your kernel info:

$ uname -r

More option in the manpage...

mrmylanman · 2011-04-23 23:35:57

I just installed this kernel on my Thinkpad X120e, which has an AMD Fusion E350 APU, it seems to work great so far!

travnick · 2011-04-24 09:37:48

Thanks a lot for the package (kernel26-pf-core2) I downloaded it from dropbox repo. It works great for me. But there is one "problem". After instaling or updating sth, pacman at the end always say:

missing dependency for virtualbox_bin : kernel26-headers

so I think PKGBUILD should include kernel26-pf-core2-headers or sth like that in the "provides" section.
Of course virtualbox module complies fine.

Of course virtualbox module complies fine.

The kernel26-pf package contains the headers but I have the following in the PKGBUILD:

provides=(${_pkgname}=${_basekernel} 'aufs2')<-># for $pkgname-optimized
# below 'provides' is for when you have no other kernel (which is a bad idea anyway)
# provides=(${_pkgname}=${_basekernel} 'kernel26-headers' 'kernel26=$pkgver' 'aufs2')

The main reason I kept it that way, was to remind me to always have a fallback kernel (the stock -ARCH in my case) to boot the system if anything went wrong with kernel26-pf (e.g. boot hang or disk failure). Adding 'kernel26-headers' to the "provides" array of the PKGBUILD doesn't conflict with the core kernel26-headers though; you can add it to the %PROVIDES% section of /var/lib/pacman/local/kernel26-pf-core2-2.6.38-pf6/desc to silence pacman and I'll have it fixed by the next -pf update.

Since pf7, the kernel-pf packages in the repo have no modules.

You might be confused because they are compressed, so a "find /lib/modules/2.6.38-pf/ -iname '*.ko'" won't list them. You'd need to use '*.ko.gz' instead.

Hm. It seems it does have modules for x86_64 and not for i686. See the file sizes:

Hello nous,

I’m having difficulties compiling tp_smapi kernel module. My first guess was I’d have to build a kernel26-pf-headers package. But since you say here that headers are included and we have -pf8 right now (and in fact, I do have a quite large /lib/src/modules tree) the problem should not be the headers but tp_smapi?

Another question: I’m using the kernel on my Intel Core i3 2310M (Thinkpad X220i, that is). Is there any advantage to install e.g. kernel26-pf-core2? Or should I stick with kernel26-pf standard?

I have to thank you so much for providing this great repository! Though compilation (with localmodconfig enabled) doesn’t take much time anymore on my new laptop, it is way more convenient to have a precompiled kernel including headers installed with any given -Syu → it’s simply great! Thank you!

Best,

Jakob

I'm terribly sorry, somehow my build machine's tailored config made it into the PKGBUILD as the default config. Only the generic i686 package is affected by it though and I'm rebuilding it right now - should hit the repo in 3-4 hours. In the mean time, 32-bit users please install one of the optimized i686 pf-kernels.

I built tp_smapi just fine in both 32- and 64-bit, see here. Can you post the error messages? Which gcc version?

The optimized kernels are indeed faster than generic ones. You won't see the impressive difference of, say, i686-vs-core2 mencoder, but it's there.

Hello,

When writing my previous post, I was wrong: tp_smapi compiled just fine. Only when trying to modprobe it I got the „no such device“ error, which is discussed here:
http://forum.thinkpads.com/viewtopic.ph … 43#p628643

I am not able to apply the patch, though and this is why I’m not able to load the module. So basically what is important at this stage of mine: I know that there are the headers included and that if the modules are working they should just work fine. It’s not kernel26-pf’s fault at all.

Concerning the optimized kernels: What I meant was if I would have any benefits usng the core2 optimized kernel with my Core i3 instead of the generic one? If I am right, they are two different kinds of architetctures so it wouldn’t make much sense, right?

Thank for your fast reply!

Jakob

Not quite. The core2 instruction set by far supersedes that of pentium-pro, and that's not the only advantage of the former over the latter. A core-i3 will substantially benefit from a core2 optimized kernel.

Ah, good to know, thanks for the hint, just switched to pf-core2

the new kernel won't seem to recognize the boot partition on my live cd, or any hard disk. I am compiling a complete vanilla kernel26-pk from AUR on a different machine I use for pkg builds. This is meant for a livecd/usb stick. instructions?

edit: also is there a new repository? the old one is down.

I've no experience in livecd/usb environments, but you might need to add the relevant filesystem modules (e.g. ext4, xfs, vfat) to the MODULES array of /etc/mkinitcpio.conf and rebuild initrd with 'mkinitcpio -p kernel26-pf'. If that fails, please report back with more information (lsmod, fdisk -l, /etc/mkinitcpio.conf and dmesg).

I just pacman -Sy'd the repository and it's up.
