unofficial linux-ck repo with cpu optimized packages is ONLINE

Stalafin · 2011-06-23 13:42:38

ethail: Thanks! I did that!

Now what remains is that I have to get kernel26-ck running with elevate=bfq enabled on bootup...

ethail · 2011-06-23 14:10:27

elevate? I'm thinking is just a typo and you meant elevator, but just in case, the kernel boot option is:

elevator=bfq

Also, you could check on your kernel config if BFQ has been built checking for
CONFIG_IOSCHED_BFQ=y
if you're building the kernel and using some menu config it's on
Enable the Block Layer -->
IO Scheduler-->
BFQ IO Scheduler

Stalafin · 2011-06-23 15:42:23

I am not building the kernel myself; I took it from the inofficial repo (see my post #296)!

graysky · 2011-06-23 15:46:27

@ethail - the pre-compiled packages do not have BFQ builtin but do include it as a module. For more, see the kernel26-ck wiki page in my sig.

ethail · 2011-06-23 16:47:05

@graysky: I just realized that instead of writing "y or m" after copying the BFQ line of my kernel config, i left that unmodified.

@Stalafin: If you're using the precompiled package with BFQ as a module, using the right image should work.

I have done exactly what was stated in the wiki:

As said before, that way seems you're not creating the right image because you're using the kernel26 preset instead of kernel26-ck. I'd suggest making a copy of mkinitcpio.conf and using it for kernel26-pf preset adding the module you need for kernel26-ck and not for kernel26. Generate the new image, and try elevator=bfq again.

Stalafin · 2011-06-23 19:06:10

Yeah, I have put the wrongly. What I meant was:

+ I add bfq-iosched to MODULES=
+ I create a new image with mkinitcpio -p kernel-ck
+ I change /boot/grub/menu.lst, having kernel /boot/vmlinuz26-ck with the option elevator=bfq and also initrd /boot/kernel26-ck.img

If I try to boot into this the boot process hangs every time at this line:

io scheduler bfq registered (default)

Here I have to reboot and use a different kernel or boot the above kernel without the elevator=bfq option.

graysky · 2011-06-23 19:27:26

@Stalafin - right... don't use the elevator=bfq line at all. Simply put a line in your /etc/rc.local that sets the scheduler for whatever HDD(s) you want. See the wiki for an example.

I'm actually going to remove the elevator line on the wiki because it's not clear to me that it works without having the module in the ramdisk image which the package currently does not provide (a separate xxx.conf).

@graysky: Alright, I am doing that now. Thanks for your input.

Do you know of a way to set up /etc/rc.local and /etc/rc.conf of a) probing bfq-iosched and b) putting bfq into /sys/bload/sd[a-z]/queue/scheduler only if kernel26-ck is loaded? I guess the latter I could do with a [[ ]] test, but I am not sure about the former.

EDIT: I really like the performance so far. It seems like it really did help watching youtube! :-D

@stal -

/etc/rc.local can do that in with a $(uname -r) and grep for ck vs. not with the normal kernel. Come to think of it, there is no reason why you need the the module in the MODULES array at all... you can have your [[ ]] test staement modprobe it if true and setup the scheduler all in /etc/rc.local.

Stalafin · 2011-06-24 10:11:34

@graysky:

[[ -n $(uname -r | grep -e '-ck') ]] && { modprobe bfq-iosched; echo bfq > /sys/block/sda/queue/scheduler; }

Seems like that works so far. :-)

swanson · 2011-06-24 11:02:17

Just installed 2.6.39-ck (not atom) on my Acer N270 atom and put this in my rc.local;

TID=$(date +%c)
KERN=$(uname -r)
if [ "$KERN" == "2.6.39-ck" ]; then
modprobe bfq-iosched
echo bfq > /sys/block/sdb/queue/scheduler
echo "$TID $KERN so started bfq for sdb" >> /var/log/slim.log
else
echo "$TID $KERN no bfq loaded" >> /var/log/slim.log
fi

Of course when "2.6.39" changes to "3.0" it will fail.
I think this is easier if you're having a couple of kernels installed, like the standard and lts arch kernels that don't have the bfq-iosched module at all. So, I don't have it built in the initrd for this machine nor do I have it activated on the kernel line. But it seems to work fine indeed.

Stalafin · 2011-06-24 13:04:47

Why don't you just use the line I provided? I mean, obviously it could fail too, but at least you don't have to change rc.local every time the kernel updates (e.g. your line would not only break for 3.0 but also for 2.6.40 :-) ).

JokerBoy · 2011-06-24 13:10:56

swanson, how about using just the localversion?

TID=$(date +%c)
KERN=$(uname -r | cut -d"-" -f2)
if [ "$KERN" == 'ck' ]; then
modprobe bfq-iosched
echo bfq > /sys/block/sdb/queue/scheduler
echo "$TID $KERN so started bfq for sdb" >> /var/log/slim.log
else
echo "$TID $KERN no bfq loaded" >> /var/log/slim.log
fi

swanson · 2011-06-24 14:49:56

@stalafin; didn't see your script until now.
@jokerboy; nice !

graysky, I'm getting the following error message when upgrading from the kernel26-ck repo:

@vlad - give it a try now. (I really need shell account so I can check md5sums on the server).

vladthedog · 2011-07-04 14:34:16

perfect graysky. Thanks for the quick fix

theringmaster · 2011-07-05 03:36:30

I just installed the kernel26-ck-k10, kernel26-ck-k10-headers, and the nvidia-ck-k10 packages from the repository. I edited the files needed for the bfq scheduler as stated in the wiki. Everything is perfect so far.. great job on this packages!

I'm curious though, can I remove the regular kernel26, kernel26-headers and the nvidia packages now? Also, how can I check whether nor not I am using the nvidia-ck-k10 module instead of the normal one. I have both installed and the Nvidia X server settings (gtk gui) doesn't seem be any different.

If you booted the ck-kernel, you're using the nvidia-ck driver. kernel26-ck loads its drivers from /lib/modules/2.6.*-ck/, so yes, you can remove kernel26, kernel26-headers and nvidia.

Hey graysky nice work on the repo, Just a question, does the kernel with core 2 flags work ok with new intel sandybridge cpus, or am i better off with the vanilla ck kernel.

Sure does. I added the info to the wiki page a while ago and also to the PKG descriptions themselves:

Ack... I think I jacked-up the groups in the generic package and in the k8 and k10 packages... the deal with the kernel26-ck thing is that I accidentally left in a provides statement in the kernel and headers package... I will fix this and repackage. Thanks for the bug report
