Is this still happening with the massive alsa update that i pulled in yesterday? If it is, i'll revert the -next alsa today.


sure, I'll give it a test-drive

independent from the outcome - could you please bump zen-upstream to 2.6.33-rc5 please ? (of course after it's clear whether the pull "fixed" it or not)

thanks !

Today/Tomorrow i'm gonna rebase master branch to -rc5 and get rid of alsa from -next as just reverting it is not gonna work.

seems like it got even worse :!:


yeah, I guess completely getting rid of next's alsa would be the best thing (hopefully that was/is the cause otherwise I will have to downgrade to 2.6.32*)

thanks :)

Well, at least for me plain 2.6.33 works really well since rc3, currently rc5, so alsa should be fine there.

good to hear, thanks ! :wink:


why was alsa from NEXT included anyways ? support for new devices that's not yet in mainline ?

We always included it in zen.git, never caused problems until now.
Also, bfq might be going away from zen.git (and thus any 2.6.33 zen kernels, unless someone is bothered to port the whole thing to io-controller and the new apis, which is quite a bit of work), it's unmaintained and it doesn't use any of the new stuff in its current state.

Ok, new master in zen.git pushed. Based on -rc5, no more alsa from -next and no more bfq.

thanks dodo ! :D

I tried out cfq with the low_latency option and everything is way more responsive

so no need for bfq anymore

PostPosted: Mon Jan 25, 2010 1:07 am    Post subject: compcache 0.6.2 Reply with quote

Hi,

as compcache 0.6.2 is available i´d like to use the new version.
compiles fine, but the patch that comes with is not applicable for mm/swapfile.c on 2.6.32-zen5/zen6.
i took a look at http://git.zen-kernel.org/?p=kernel/zen.git;a=blob;f=mm/swapfile.c;h=d5eb2e85600b359d498dc3e148a0b1465863e45a;hb=d4906e1aa516cc965292b43b5a26122dd4344e7e (swapfile.c from current zen.git) which is slighly different. i´m not quite sure if i simply may replace my include/linux/swap.h, mm/page_io.c and mm/swapfile.c with the ones from this commit http://git.zen-kernel.org/?p=kernel/zen.git;a=commit;h=d4906e1aa516cc965292b43b5a26122dd4344e7e so that i could apply the compcache-patch...

any suggestions?

PS: hope it´s ok to post here although i asked on zen-kernel mailinglist already...

thanx in advance

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
edit:

nargh, stupid me ^^

compcache already is in zen :lol:

nonetheless... i would very much appreciate to see you guys updating compcache to 0.6.2 for 2.6.32-zen5/6 as i´m too confused because of the differing swapfile.c, although ccache 0.6.2 is said to be working with 2.6.32 ("Jan 25, 10 - compcache-0.6.2 is released. Contains lots of cleanups, fixes, works with kernel 2.6.32 and xvmalloc is no longer a separate module. ")

you´re all doing great work, thanks!

Make sure you read the description ;)
It should be ideal for ssd's, someone could test it out and report 8)

it looks like it works fine also on my notebook SATA drive. :)

Tried it on my non-ssd drive as well and it feels quite usable.

I guess on SATA the presence of NCQ in the disk itself would dampen any negative effects from changing the in-kernel scheduling.

Currently working on BFQ port to 2.6.33 and io-controller, this will take a bit of time but should be finished by time 2.6.33 is stable 8)

The kernel firmware loader seems to be really screwed up on one of my boxes. Anyone else seeing huge delays like these?
Code:
[    3.854918] usb 1-3: firmware: requesting isl3887usb
[   63.850097] usb 1-3: (p54usb) cannot load firmware isl3887usb (-2)!
[   63.850107] usb 1-3: firmware: requesting isl3887usb_bare
[   63.864468] phy0: p54 detected a LM87 firmware
...
[   77.249581] microcode: CPU0 sig=0x106c2, pf=0x4, revision=0x208
[   77.249594] platform microcode: firmware: requesting intel-ucode/06-1c-02
[   78.110012] eth0: no IPv6 routers present
[   87.082512] wlan0: no IPv6 routers present
[  137.240111] microcode: CPU1 sig=0x106c2, pf=0x4, revision=0x208
[  137.240124] platform microcode: firmware: requesting intel-ucode/06-1c-02
[  197.240195] Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Oruba
[  197.350007] microcode: CPU0 updated to revision 0x218, date = 2009-04-10
[  197.361931] microcode: CPU1 updated to revision 0x218, date = 2009-04-10

Everything still _works_ afterwards, but those 60 second delays are crazy...

(I've checked the disk /lib/ is on using `smartctl -t long` too, with no errors)

Whats the deal with Reiser4 and current kernels? Has it gone the way of the dodo?

And also what are the odds if I go with btrfs that I'll lose everything in a catastrophic spectacular fashion?

I recently reinstalled everything and went all reiser3 just to use the newest kernel. I was re-introduced to that annoying firefox3+reiser3 sluggish startup that is so annoying.

I lost everything within a day when I mounted my root partition on my ssd with ssd,compress,noatime on the 2.6.33-rc4 kernel. If you try btrfs, you will probably lose everything too.
