The linux-pf thread; BFS/CK, TuxOnIce, BFQ, AUFS3

Is that supposed to be a "superior" version of the conservative governor? (found my answer).
btw: how's the state of tuxonice? I don't use an initramfs so tuxonice really interests me

Never mind, the new cpufreq governor breaks compilation and I disabled it in the PKGBUILD until someone who's interested finds a solution. Tuxonice works uncompressed; however, its author has been notified of the problem and promised to look into it.

It didn't broke anything using this url to get the patch:

https://raw.github.com/gist/1172524/695 … file1.diff

and this to apply it:

  patch -Np1 -i "${srcdir}/gistfile1.diff"

At this moment I'm using it, running on a testing linux-zen using the PKGBUILD from heftig's repo as guide. PKGBUILD used to build it:

https://github.com/alferpal/ArchLinux-S … /linux-zen

I'll edit this when I can confirm it doesn't break -pf build that way (slow conection right now so ~20min to get the sources)

EDIT: clean build

:s I'm using it with linux-pf (pkgbuild from the aur) and nothing is broken

Do you experience any better interactivity with this govenor? Best regards!

nous · 2011-09-01 14:31:01

Guys, currently the PKGBUILD of linux-pf does not apply the interactive governor patch, unless you uncomment the 2 relevant lines. Have you uncommented them?

Before, I used the exact same patch which applied cleanly, but the last stage of compilation failed.

  OBJCOPY arch/x86/boot/compressed/vmlinux.bin
  HOSTCC  arch/x86/boot/compressed/mkpiggy
  XZKERN  arch/x86/boot/compressed/vmlinux.bin.xz
ERROR: "sched_setscheduler_nocheck" [drivers/cpufreq/cpufreq_interactive.ko] undefined!

el mariachi · 2011-09-01 14:59:59

I didn't uncomment anything but the option to enable the governor was there in menuconfig and right now yacpi says my governor is "interactive".
I built the package this morning (GMT), has it been since that?

ethail · 2011-09-01 17:14:04

nous: I downloaded your current llinux-pf tarball, unpacked, replaced your lines with mine, makepkg -g to get md5sums, build, no error.

I'm going to do it again in another machine and I'll post the PKGBUILD here.

This will get edited in ~20 or so

EDIT:

It took a bit more than expected, but clean build again:

There is the PKGBUILD

ethail: that linux-zen PKGBUILD isn't working for me though... problems with cpufreq. I'll look into it..

ethail · 2011-09-01 18:29:46

el mariachi:

you mean the one in my github repo or the one I've just pasted?

The latter is -pf, not zen. About the zen in my github repo, it's likely to fail. I think it was just written to not fail me some night and I still haven't had time to correct it

Also, always remember to wipe the src folder before building, patching is likely to fail if not done that way.

EDIT: also, are you modprobing the interactive governor and so on?

el mariachi · 2011-09-01 21:08:56

the one in your repo failed, the -pf from aur works flawlessly. I don't compile the kernel with modules, so no need for modprobing stuff. Interactive is working fine, I don't have time to benchmark and compare it to the others though.

OT: I like the zen kernel and use it.. it seems very quiet lately

nous · 2011-09-01 21:12:00

ethail: It still fails with the PKGBUILD you provided, and why wouldn't it? Both PKGBUILDs download the same patch and apply it likewise.

But since others (el mariachi) reported success, there must be something rotten in my system.

el mariachi · 2011-09-01 21:15:12

nous: yes, both the PKGBUILD from ethail and the one in AUR use the same patch and apply it in the same fashion. That is the error I get with the PKGBUILD for -zen... maybe the patch has been updated and it broke stuff?

ethail · 2011-09-01 21:32:15

@el mariachi: unlikely, page shows no change since Aug 26th. I've tested it right now.

By the way, the zen PKGBUILD was quoted as example, nothing more.

@nous: That's kind of really odd. I've tested that patch against -pf several times on two machines and it never gave an error. Both machines are x86_64

Well, not so odd, maybe:

https://gist.github.com/1172524#gistcomment-47437

Only tested on x86_64. Use at your own risk

I think I will stop using it until it gets better.

el mariachi · 2011-09-01 21:40:42

I'm using x86_64 too.. and only now I noticed that my cpu is stuck at 800Mhz.. (it isn't slow though ) humm I think I'll a bit longer for this to mature too..

My laptop is idle most of the time but it scales up to 2.2GHz as needed.

So is mine with the on-demand governor, but I haven't tested the interactive one. Have you compared the two and seen a significant advantage of the latter?

I haven't had time yet to sit down and do a side by side comparison of battery life with the interactive vs on-demand governors. One of these days I'll get around to it and report back.

i686 repo seems to be maintained worse than the x86_64 one - kernel packages there are still at 3.0.2 and some nvidia packages are missing. I'd like to run the latest linux-pf, but due to the downtime of kernel.org I can't build my own packages.

Well, if git is good enough you could try https://github.com/torvalds/linux I suppose.

Cheers.

I'm sorry, the packages had been built days ago but I had forgotten to run repo-add. As for the nvidia packages, well, I don't actually have a i686 box with nvidia and I don't really update the driver...

While original Arch kernel works fine, linux-pf stuck at boot and show "/etc/rc.d/functions: find: command not found" after "Remove leftover files". Clearly something wrong with linux-pf and rc.sysinit. Any ideas to fix? Thanks.

I found the cause. SOLVED.

Thank you for precompiled packages, i've the feeling of a nice speed boost using it on an atom n280 netbook.

Anyway, it seems that powertop doesn't play good with your config:

No detailed statistics available; please enable the CONFIG_TIMER_STATS kernel option
This option is located in the Kernel Debugging section of menuconfig
(which is CONFIG_DEBUG_KERNEL=y in the config file)

Can you please enable it?

EDIT:
If you are wondering, that option has "almost zero" overhead:
