2.6.12-rc3-love1 "Ricer Eunt Domus"

Sith_Happens · Posted: Mon May 09, 2005 2:24 am Post subject:

Hey fallow, where can I get a hold of the patches for the the genetic schedulers, both I/O and CPU? The performance I've seen under a high load with the love kernels is phenominal, and I'd like to apply those scheduler patches in some of my homebrew grsecurity kernels (not for general consumption, sorry

). With CK sources you can download all the patches online (which I do :wink:

), but it doesn't seem like you ever did that with love-sources, unless I'm mistaken. I've been using staircase with my grsecurity kernels, but it seems to crap out on me with loads above 2, where as with love-sources I can be compiling glibc, watching a movie, and running a medium-traffic web server simultaneously with no perceptible performance hit whatsoever in any application (I hope to offload these functions to seperate machines in the near future, but right now I'm strapped for cash). If you could just point me in the right direction to find the patches I would much appreciate it. I anticipate alot of trouble getting these patches to apply to a grsecurity kernel, so I'll probably have to hack it together. But thats the fun part right?

Thanks for the links guys. I managed to get all the genetic patches to apply to a grsecurity/PAX patched kernel with little fuss. I'm going to give genetic zaphod a try and see if the performance gains are really greater than with the genetic nickscheduler. Thanks again.

Well, this kernel I'm building is going to be for a dedicated server, I still use love-2.6.11-love2 on my desktop. Perhaps I will try patching with the Genetic Nickscheduler for a desktop grsecurity kernel, but I've found that grsecurity is a PITA for desktops, so I'd rather just put my desktop behind a dedicated firewall, run no services on it, and stick with a love-sources kernel.

ok, i took your word for it and switched from reiser4 to ext3. I have to admit that with your kernel ext3 is way more responsive than reiser4. I never had problems with reiser4 so I stayed with it, but I decided to switch because my emerge sync's would take forever and my CPU usage would always be 100% because of the disk access.

My system is so much more responsive now following your advice. I used the Anticipatory I/O. Which do you recommend?

Also, there are two requests I would like to make and see in the next patchset. The 1G low mem support, and LUFS support. I guess I can live with the highmen implementation, but I need LUFS so that I can read and write my NTFS disks. And the latest captive-ntfs does NOT work with fuse and lufis. It only works with a patched kernel version of LUFS.

Thanks though for letting me see the light with ext3.

sorry Fallow, no go on my opterons, breaks somewhere in smpboot.c ... are you bored ? should i send you the output ??

BUT working nice on my other amd-xp box with default settings, good job !!!

One request : what are your opinions about the sched stuff in -mm ??? Can you give this a try in next love ???
Im running a self patched kernel with all the mm sched + amd64 patches here on my amd64 boxes and it feels at least a bit snappier; just my impressions of course, have no numbers. Did someone test this ?

And I think we already talked about this, but for those brave guys out there using ext3 give this a shot, looks promising but is still beta code http://abiss.sourceforge.net/ (Im not saying to include this in love of course, just to let you know

)

cheers

Ok, I will give it a try next week.

Got an new hd, making a new system.

We will see how the new system with love + ext3 + nginit-system will compare to my currently System (nitro + reiser4).

@all who are still thinking, performance is all and reiser4 is overall:

Why the hell should reiser4 be included in a DESKTOP-Kernel? Can anyone give me a good answer to this question?

Could not be the performance, when the high CPU-Usage/Ram-Usage gives the latency a big a..-kick.

my question was about the disk I/O, I used cfq-ts for the scheduler.

Ok fallow,

I had hardlocks when I was starting startx, too. First I wasn't sure what was the reason, but now I am. My PC also freezed when the terminal got black, so I thought it was a problem of vesafb-tng. After that I compiled the kernel without vesafb-tng and everything runs fine. But a question what I ever wanted to know:

Isn't it better to use the Nvidia-framebuffer-driver instead of the vesafb-tng?

skarthesatai · n00b Joined: 20 Apr 2005 Posts: 16

I think it is better to use the vesa-tng.

2. reasons

a. The vesa-tng is much more stable. I am using Linux since 7 years and i had never get the rivafb/nvidiafb get working. Every time i get black-screens or fragmented displays and i am using nvidia since the same time. I never overclocked my card, got so many different cards nothing worked for me.

b. As more Users try the vesa-tng instead of any other drivers, the bigger the chance to get it included in the main-kernel. The old vesa-stuff is deprecated in my opinion.

just found the time to copy / and /usr to ext3 to finally test this

wooooohaaaaa

maybe placebo for first but damn this feels faster as the -ck i used the last time, which again has been faster for me than last love. i'll try to get it skipping sound under high load while moving around some huge amount of files... and give it some days uptime

i have vesa-tng compiled in, but disabled at boottime (makes not that much sense, i know) with video=vesafb,1024x768... and no probs at X startup

ok, now it's time to stress this nice love'ly thing, hehe and see how things go. and i have to get rid of my reiser4 /home it seems

well, on emerge sync things are really slow with ext3 @ cfq-ts i have to admit, maybe i should throw /usr/portage on reiserfs or reiser4 again...
and multiple compiles at a time take quite long, but the desktop keeps being more usable, very nice so far, didn't manage to get audio playback skipping even at a load of ~9, on -ck+reiser4 it started skipping at about 7

i love that love so far

what do you guys use for /usr/portage? is it /usr/portage that is responsible for syncs?.. should be as a sync causes a huge amount of small files... the difference to reiser4 is really massive, no idea how it would be with reiserfs... must test

OK Guys , great to hear that opinions

about question about *fb , and X freezing after startx + vesa-tng , just dont compile vesatng into kernel.

about interactivity great to hear good opinions

about long time of emerge sync. hmmm

My time of updating portage cache is around 30-40 seconds now. and I dont have a rocket ( amd1.0, via kt 133 ) .
ext3+dir_index and portage + python-cdb .

this maybe can sound strange for first hearing but please take a look on portage responding time if You will put it into ext2.
hehe this is really impressive

do some portage operations with ext2 based portage.

yeah yeah I know that "there is a lot of small files , this is reiser* heaven " , easy , take a look

of course I meaning not only /usr/portage in ext2 but also the place where is used to doing cache updating etc.

are some methods on the forum , to partial doing it in RAM also

yeah , without journalling some things can be just faster . but some not

and without journaling is more risky.

cheers.

ps.
rc4 based release very soon.

RT-Limist are in vanilla now

jfs fixes , reiserfs fixes and some of ext3....

gringo @ of course thanks for the idea. Im not sure if we requiring the abiss for destkop usage . but I will do proper testing. maybe I just do implementation of genetics for Ingosched ? ? hehe, just joking

... Im interested also in swap_scheduling idea which Lovechild introduced me. of course no early enthusiasm . testing first

and about sched fixes in mm , this is in 90% multiprocessor Nick Piggins fixes , but ..hmm.

I willl see

some of them are also in rc4 now

cheers .

Im going to bed

AHH we have also love-sources logo competition . If someone is interested in doing a logo . please send graphic in 80x80 resolution to fallow@lovesunix.net

actual gallery -> http://vivid.dat.pl/fallow/pub/index.php?dir=love-sources/love-logos/

Could LIRC patch be added in new love-sources?
That would be nice!

Thanks.

So fallow, you recommend just using ext3? I'm using JFS right now, should I just stick with it or switch to ext3 + love?

I'll also have a neat logo ready for you tomorrow once I get done with my finals.
