Nice news... Isn't they...? And, it seems it works. I did not compile yet but I'm using some patched kernels now, just for the fun of it... :)

I'm thinking your referring to the Fast Desktop patch as explained here.

The patch explained(?!) here.

This is the first time I came across any info on the autogroup patch.

I wasn't sure what you were referring to so by accident I came across the patch while reading the LXer News.

#3

Sorry, I was not precise enough... But, nevertheless, we are talking about the same patch...

#4

I'm already using this patch (since yesterday). Patched 2.6.37-rc2 with it and I'm absolutely amazed by the improvements. Couldn't see any negative effects, just positive ones - like being able to watch BD-movies while compiling the kernel in the background or much better - subjectively felt - responsiveness in everyday-applications with BOINC steaming ahead in the background. I can also confirm (subjectively, not tested) webpages to load faster. Very nice indeed.

#5

is there a ppa with this patched kernel ?

#6

for 10.10 too if possible :)

#7

Currently I'm using liquorix 2.6.36 ... :) Even though this patch should be useful for those that use lot of tty, I think I get snappier desktop, better flow and snappier web pages. I did not make enough time to compile 2.6.37 with only that change so I could be sure what is responsible for my feeling and better measurements... It is not important, though, we are looking into a better future... :)

I added that liquorix to my repo for Lucid and it IGN's it. What is the source you used for sources.list ?

thanks.

Hey Zika, you find anything broken when you installed this? I'm just wondering. I'd like to give a whirl, but I don't want to break anything.

#11

I just read about this on this blog, and I want it. However, the instructions on the blog is not noob friendly so I'm not getting anywhere trying to make this work: http://www.webupd8.org/2010/11/alternative-to-200-lines-kernel-patch.html

That's exactly the link I used. At first the keyring errored out, but I got that to work. I put #/etc/apt/sources.list.d/liquorix.list deb http://liquorix.net/debian sid main on my sources.list but nothing happened.

No guarantee. If I have noticed something wrong, believe me, I would have reported... :) It's just a kernel... :)

deb http://liquorix.net/debian sid main on my sources.list but nothing happened. Update. Install linux*liquorix*... 2 files... It is the same as if You were to install Ubuntu kernel, just without _all.deb... :) I have „deb http://liquorix.net/debian sid main future“ ...

I think the current names are: linux-headers-2.6.36-0.dmz.13-liquorix-amd64 and linux-image-2.6.36-0.dmz.13-liquorix-amd64, in my case...

I know I'm missing something here. This is all I got at sources.list:

deb http://liquorix.net/debian sid main

EDIT: When I update, I get the following:

I just did Lennart's solution on my netbook running Unity. It does feel faster, and it's much easier than compiling a new kernel. :)

Yup also running it but LennartP is hard on Linus...;)

I am running on a i3 laptop with an Intel SSD and I cannot see any differences.....

Must load up an 1080p movie and a heavy Compiz rebuild at the same time and retest ..:D

#18

Just to do restart... :) Thank You... We will see if it collides with liquorix kernel... :)

It works with 2.6.37-999... It works with liquorix kernel, also. It is optimized in more other ways than just this, so...

#19

Any experiences on using this and the brain **** scheduler together, or are they mutually exclusive?

#20

It is funny to read that Linus and that Poettering guy are completely in love: http://marc.info/?l=linux-kernel&m=128992756502756&w=2

And Peter Zijlstra as well :popcorn:

#21

Linus' reasoning against the userspace implementation as suggested by Poettering is pretty sound. Putting things in the kernel makes implementation and usage more universal.

#22

It is an optimization for a silly load ( running 64 threads at once with far fewer cpu cores ) that has been blown absurdly out of proportion by Phoronix.

#23

As they usually do.

They're a Linux tabloid.

And there's enough kernel drama to write about. :P

Good description... I hadn't thought of that one when trying to classify them.

#26

This just got included in the Natty kernel:

[ Tim Gardner ]

* [Config] CONFIG_SCHED_AUTOGROUP=y

[ Upstream Kernel Changes ]

* sched: automated per session task groups
