unofficial linux-ck repo with cpu optimized packages is ONLINE

graysky:

There is something I think you would like to know, -pf and zen are using BFQ for 3.0 and comparing the BFQ sched files in their current kernel code against the one used by -pf in 2.6.39 return 0 changes.

Could it be that there isn't a 3.0 BFQ release because it doesn't need to be updated?

@ethail - thanks for the heads up. The BFQ those packages are using is a hacked version from 2.6.39. I contacted Paolo about it a week or so ago and this is what he had to say:

Subject: pf patchset includes BFQ for 3.0?

Unfortunately no, I did not yet find the time to complete the new version. The bright side is that it will not be just a port to 3.0, but it will contain new improvements.

graysky > as you can see in core repo http://mirrors.kernel.org/archlinux/core/os/x86_64/ there is a special archives *.files.tar.gz. It is needed by some tools like pkgfile

sudo pkgfile -u

No update available
:: Checking [extra] for files list ...

graysky · 2011-08-31 20:59:03

@Crayon - interesting... I see, the filename differs, pkgfile wants repo-ck.files.tar.gz not repo-ck.db.tar.gz -- this is odd because I am using repo-add right out of pacman to generate the repo index. See, this wiki page.

EDIT: I simply renamed http://repo-ck.com/x86_64/repo-ck.db.tar.gz to http://repo-ck.com/x86_64/repo-ck.files.tar.gz and pkgfile didn't complain:

: Checking [repo-ck] for files list ...
:: Downloading http://repo-ck.com/x86_64/repo-ck.files.tar.gz ...
:: Checking [router] for files list ...

Please test and let me know if this works. If so, I can provide this file upon an update to the repo.

graysky > thx, everything works fine now I guess pkgfile should be adjusted to work with both .files and .db prefix...

-f, --files
Tells repo-add also to create and include a list of the files in the specified
packages. This is useful for creating databases listing all files in a given sync
repository for tools that may use this information.

Short question: Do you think about providing the interactive governor as an optional setting with your repo or pkgbuild?

Best regards!

ethail · 2011-09-03 09:11:22

Lothium: That governor can break builds in 32 bits and be some kind of unstable.

Follow some discussion about it on the -pf topic:

Lothium · 2011-09-03 09:30:39

Ahh ok thank you very much for your answer!

graysky · 2011-09-03 12:42:33

I made a little update to the first post of this thread.
*Added an index to the repo.
*Added a link to server statistics (package popularity, # of downloads, etc.) with colorful graphs.
*Simplified the post.

sxe · 2011-09-12 09:13:28

Hi graysky, at first thx for your work and providing these packages, so i don't have to build them by myselfe.

I'm fairly new to this ck stuff and never used it before. I installed it for my i7 cpu + the nvidia counterpart and added a new entry to my menu.lst so i think i'm ready to go.
Is there anything else i should do?

Is there any good kernel benchmark you can recommend to me?

And a last question. I did read the Con Kolivas' BFS FAQ you mentioned in the arch wiki and he is only talking about BFQ (*edit ah, i think i mixed BFQ and BFS here?). What else do this patches imply?
Regarding my last question. Whats the point of this kernel when BFS is disabled, cause its not yet available for 3.*? Could you enlighten me about this too?

*edit: There seems to be a problem on my system. I cannot boot the ck kernel. After the arch logos i get a shit load of error messages and traces and stuff. Does anyone know where i can find this messages later? Any logfile? The ones in /var/log/ only seems to show the messages from the normal kernel.
The second boot did raise any errors.

*edit2 Some Systeminfos:
Graphics card: Nvidia GTX 275
CPU: Quadcore i7
Arch: 64bit
HD: Root sits on SSD drive

Thx

I am using p4 kernel and is working lovely. If you like I can host a mirror at http://www.foxjames.co.uk. Not sure if this helps our friends in China.

graysky · 2011-09-12 20:15:24

@sxe - Nothing really you need to do beyond boot into it - CK has done the tuning for you. As to benchmarks, nothing major. The whole point of BFS is responsiveness which is difficult to benchmark. You are the best judge of how snappy your system feels.

@gazj - Dunno what's required for a mirror; no major interest on my part but thanks for the offer.

It seems that Paolo has finally released yesterday the patches for the 3.0.0 kernel

http://algo.ing.unimo.it/people/paolo/d … hes/3.0.0/

sxe · 2011-09-21 09:43:12

Is it possible to enable BFQ for all devices wthout adding "echo bfq > /sys/block/sd*/queue/scheduler" to all of them?

And an other question. Does it work with ssd devices? My root partition is a ssd for example.

Thx

Yeah, add elevator=bfq in your kernel line in grub IIRC.

There's no reason it wouldn't work.

I just tried the BFQ thing (added the elevator line to my GRUB kernel cmd line), but apparently I don't have BFQ:

[    1.535965] I/O scheduler bfq not found
[    1.864062] I/O scheduler bfq not found

I'm using the -corei7 kernel.

You need to add the module to your initrd.

MrCode · 2011-09-21 21:48:01

Forgive my cluelessness, but I can't seem to find anywhere to do that…if I try to add it to the MODULES line in mkinitcpio.conf it just gives me a "not found" message when I try to rebuild the ramdisk:

[root@lappy486 mrcode]# mkinitcpio -g /boot/initramfs-linux-ck.img
==> Starting build: 3.0-ck
==> ERROR: module not found: `bfq'
  -> Parsing hook: [base]
…

I can't find anywhere on the wiki that describes where to add it, either…is there something I'm missing here?

Looking back at previous posts, could it be because I'm on the 3.0 kernel?

If this is the case, then I feel stupid.

Oh yeah, graysky might not have added it yet since he wanted to wait for an official patch, and that just came out recently. Sorry.

graysky · 2011-09-21 23:48:50

@all - it's been a brutal work week and tomorrow looks no better. I just updated the AUR package with version 3.0.0 of BFQ. To answer the questions about why the repo package doesn't have it is simple: when I compiled the repo packages it wasn't available Now that I released 3.0.4-2, I will rebuilt the repo and refresh it.

Well, things seem to be working now:

[mrcode@lappy486 ~]$ cat /sys/block/sda/queue/scheduler
noop deadline cfq [bfq]

…but I still got an error about the bfq module not being there when pacman ran mkinitcpio after installing the new kernel. Does this mean that BFQ has been built directly into the repo kernel, and doesn't have to be loaded as an initrd module or something?

Please forgive me if I'm way off on this…I'm not exactly an expert on how the initrd system works.

@Mrcode - You are 100 % spot on. Check the wiki for the notice:

How to Enable the BFQ I/O Scheduler
Since release 3.0.4-2, the BFQ patchset is applied to the package by default. Users need only enable the BFQ scheduler to use it.
