Realtime kernel, 2.6.29-rc4-rt ?

Fackamato · 2009-02-21 17:40:41

Is anyone still interested in the realtime kernel? I saw that there's a realtime patch that can be applied to 2.6.29-rc4:

http://www.kernel.org/pub/linux/kernel/ … c4-rt2.bz2

http://thread.gmane.org/gmane.linux.rt.user/3911

I request an update of the kernel26rt PKGBUILD in AUR

I just built it myself and made a PKGBUILD (very ugly one) that seemed to work

[fackamato@fackamato-laptop ~]$ uname -a
Linux fackamato-laptop 2.6.29-rc4-rt #1 SMP PREEMPT RT Sat Feb 21 17:17:18 GMT 2009 x86_64 Intel(R) Core(TM)2 Duo CPU T8300 @ 2.40GHz GenuineIntel GNU/Linux
[fackamato@fackamato-laptop ~]$

But that was build in my ramdisk, and I forgot to copy it to my HDD after build+install so I lost the PKGBUILD

Hey Fackamato,

I need RT and saw it was outdated. The maintainer looks like he wants out. I don't really have time to maintain a kernel package but I need RT for the Linux CNC package I am putting together.

Let me know what you want to do. I am going to be putting a PKGBUILD together this afternoon if I can get a free moment to work on it.

Hey,

Unfortunately I don't have the time to maintain any packages. Perhaps if you could come up with a PKGBUILD that works and just post it here would be enough (and post it as a comment on the aur page)

The PKGBUILD really only needs to apply kernel patches, but I remember I had trouble with kernel naming, localversion etc. There was a localversion-file in one patch (rt I think?) that made the package fail to build because it was expecting the kernel tree with another name etc.

digitalcrypto · 2009-02-26 20:33:47

I'll see what I can do but no promises. I'm on a netbook..nuff said.

I grabbed the latest tarball to have a look.

digitalcrypto · 2009-02-26 20:51:29

Those kernel boys are definitely quick.

Latest is

http://www.kernel.org/pub/linux/kernel/ … c6-rt3.bz2

So I will try building against that for now.

digitalcrypto · 2009-02-27 04:33:56

I got a PKGBUILD running on make now. It's 2.6.29-rc6-rt3.

Do you know where I can host the file so I can put a link in here and people can download it?

evr · 2009-02-27 04:52:22

do you think you could either post the PKGBUILD or post it in the AUR?

digitalcrypto · 2009-02-27 04:57:40

Yeah. I wanted to build/install it to make sure it was ok first. I sent Schiv an email about assuming the role of maintainer for it since I need RT for Linux CNC and I will keep it updated.

I will zip and post to rapidshare and put a link here I guess until Schiv tells me what he wants. I will do that within the next hour or so.

evr · 2009-02-27 05:04:02

sweet, thanks.

digitalcrypto · 2009-02-27 05:58:25

Sorry. I am super tired so this isn't quite done but it will start building the kernel. I'm still compiling.

here is the link. i've not matched up md5sums etc

http://www.divshare.com/download/launch/6667792-72b

If you have problems/suggestions leave me a message and I will get it in the morning when i wake up.

Cool. I didn't get that far. It's taking me about 2h5m to compile this on netbook.

Thanks for fixing that up and let me know how it works.

Would you be so kind to post the package somewhere?

Thanks

Well it didn't work completely. mkinitcpio fails to find any modules because it's looking for 2.6.29-rc6-rt in /lib/modules, where only 2.6.29-rt is. I made a symlink to 2.6.29-rc6-rt but that wasn't enough, I needed to run mkinitcpio -k 2.6.29-rt -c /etc/mkinitcpio.conf -g /boot/kernel26rt.img instead of -k 2.6.29-rc6-rt... there's some quirks left to fix in the PKGBUILD etc to avoid this, but since I fixed these manually, the kernel boots and works with nvidia etc.

However, I forgot to enable my wireless network card so I'm on my newly compiled -zen instead. Now food, might compile -rt again later...

I just noticed that there are patches that apply to 2.6.26.8 if someone wants to try them: http://rt.et.redhat.com/download/

digitalcrypto · 2009-03-03 10:10:46

I saw and I made a PKGBUILD for it. If my memory is correct, and it's usually not when I am working graveyard, PREEMPT was/is/needs to be removed to be stable. So no Core2Duo, Quadro multi on it.

But I could be wrong...

I'm pretty sure that means your _kernver variable is screwed up in your pkgbuild.

ugkbunb · 2009-03-15 02:32:27

I can build the rt kernel (rc7 version) just fine (had what the above mention poster problem but making sure my .config kernel version variable was set right fixed it.) However I can not for the life of me build the nvidia kernel interface.

I have tried the following:

1. wiki instructions of editing the makepkg to my kernel version
2. booting into my new kernel and using `uname -r` in the kernel version fields
3. attempting to manually install using sudo sh nvidia package.... with -k to signify my kernel and within the new kernel enviroment. I have also tried passing --kernel-source-path as well as setting SYSOUT/SYSSRC in the PKGBUILD.
4. I have attempted to adding the following to the PKGBUILD as well as editing the standard 2.6.28-ARCH pkgbuild to accept the realtime patch.

msg "Copy arch includes for external modules..."
mkdir -p ${pkgdir}/usr/src/linux-_kernver/arch/x86
cp -a arch/x86/include ${pkgdir}/usr/src/linux-_kernver/arch/x86/

I can verify that the following exists.
/lib/modules/[my new kernel]
/usr/src/linux-[my new kernel]

file /lib/modules/[my new kernel]/build
properly points to
/usr/src/linux-[my new kernel]

I have also tried the following which someone suggested fixed it for them
sudo ln -sfn /usr/src/linux-[my new kernel] /usr/src/linux

All of the above fail with the same error. Nvidia complains that it can not find the source for the kernel.

on your system.
If you are using a Linux 2.6 kernel, please make sure
you have configured kernel sources matching your kernel

output directory using either the "KBUILD_OUTPUT" or
the "O" KBUILD parameter, make sure to specify this
directory with the SYSOUT environment variable or with
the equivalent nvidia-installer command line option.
Depending on where and how the kernel sources (or the
kernel headers) were installed, you may need to specify
their location with the SYSSRC environment variable or
the equivalent nvidia-installer command line option.

EDIT: Fixed it by changing my symbolic link to the source directory I built my source one not the copy of it in /usr/src

Which rt patch did you use? Any PKGBUILD?

ugkbunb · 2009-03-16 05:32:33

^^
I edited the one posted. I did make a hackish one from the stanard kernel PKGBUILD in the ABS and it did install fine just had the same issue with the unable to find the source. I used teh rt-rc7 patch and patched the rc7 source I assume it does not apply cleanly to the newer rc8 source (did not test).

Fackamato · 2009-04-06 02:19:27

The latest patch can now be found here: http://www.kernel.org/pub/linux/kernel/ … .1-rt4.bz2 . I assume it can be applied to 2.6.29.1, but I haven't tried.

Someone should report back if things work, I don't do any audio stuff myself. Are there any other areas the rt patch might help? Desktop responsiveness?

Edit: Here's a PKGBUILD for the daring people. Can probably be used with kernel26rt in AUR:

You can probably take the config files from kernel26rt in aur and do make oldconfig. Something is not right though, in order for NVIDIA to build I had to manually specify --kernel-source-path=/path/to/kernel26rt/src/linux-2.6.29 , but then it built fine.

I can build the rt kernel (rc7 version) just fine (had what the above mention poster problem but making sure my .config kernel version variable was set right fixed it.) However I can not for the life of me build the nvidia kernel interface.
*snip*
EDIT: Fixed it by changing my symbolic link to the source directory I built my source one not the copy of it in /usr/src

Thank you sir! I was going crazy trying to figure this one out. In the end a simple

rm /lib/modules/$(uname -r)/build
ln -s /<path_to_src>/linux-2.6.29 /lib/modules/$(uname -r)/build

did the trick. Wonder what's different about the RT PKGBUILD.

Unfortunately, package makes, but installing gives the error that module 'nvidia' is not found in /proc/modules, and I can't boot with nvidia in the xorg.conf. Any advise, seeing as you've solved it?

EDIT: when I try to modprobe nvidia I get:-

FATAL: Error inserting nvidia (/lib/modules/2.6.29-rt/kernel/drivers/video/nvidia.ko): Invalid module format

Nvidia forums suggest that the kernel and module were compiled using different gcc versions, which isn't possible because I just finished compiling the kernel before trying to install the driver.

So, I believe my previous error was from having ARCH being 2.6.28, now that ARCH is at 2.6.29 it doesn't happen anymore.

Anyway, I've been examining the PKGBUILD, and have made some changes which allow compilation of nvidia kernel module without the hackish linking of /lib/modules/$_kern. Only 2 changes, first is adding 'trace' to the list of include directories copied, second is copying arch/x86/includes over. Both of which I believe are needed, the 2nd of which doesn't work without the first. Its late here, so I haven't tried if the first will work without the second. I've indented the relevant lines for ease of use, the rest of the PKGBUILD is exactly the same as the current one.

Anyway, if schivmeister could modify the PKGBUILD with these changes it would be great. Thanks so much for uploading this package, by the way.
