linux patch that MASSIVELY improves smoothness

http://www.phoronix.com/scan.php?pag...37_video&num=1

This is a 200 line patch that according to linux was according to Linus the most impressive result of code that is elegant - 200 lines long - and should be wound into the phone linux as well

---- edit - and here is why it isnt going to be of any use for us...

Phoronix(and Linus) say that is a miraculous 200 lines patch to increase interactivty? Can you consider the inclusion, of course if group scheduling in android 2.6.32 kernel is compatible?
the process groups are created per tty, that wont work on android
you can create process groups by hand however but it doesn't make a lot of sense for android in that case. the goal is to have some intensive tasks into their own group, but theres no intensive tasks and we don't have issues like audio or video lagging

their tweak is especially good if you run a compilation in the background and want to browse the web while waiting without having slow downs.

on android if you browse the web you dont have other cpu heavy tasks in progress usually (like encoding a video or what not)

i hope that was clear enough

I've off works urlaub would bei awesome

Where are the developers, who can say, if it works?

Already discussed - its useless on phone. Phone will be even slower.

Lets save statements like these after it has been actually tested.

Not everything needs to be tested. If you make a program to draw a circle, it wont make a square, let alone cook eggs. (it's the case for this patch at the technical level, beyond the "wow" words from 1st post)

Note: there's other patches in 2.6.37 for responsiveness which are different from the one spoken about here which are actually likely to improve things. But probably not as drastic.

Got any links to where I can find out what you know?

I was *hoping* that if it made desktops much more responsive under heavy loadings that it would help with the phone - its not like we have slow cpu's in these things Or is it cpu architecture that allows the improvments and the phones just are not compatible? or something else?

just wanting to know more and to hopefully get a dev who thinks its worth taking a look to see - 200 lines of code - *cof* (ducks behind armour) "how hard could it be?" *runs for cover*

i get this sinking feeling from the subtle - and not so subtle comments from you guys tho - that its just not really suited for how android works on a phone....

Read last 5 pages in hardcore kernel topic.

knowing one and the other about linux, I have to disagree with those who say: it's gonna make your phone slower..

why? in linux, things constantly run in the background. and what this patch does, is give priority to foreground processes. True, there isn't MUCH in the background, so results may not be super, but the compile with 64 threads is just AN EXAMPLE of what it can do. That's the PERFECT situation to demonstrate. This doesn't mean that it sucks for everything else! It just means that it works

So stop bitching and just test it before you start yapping that it's bad, doesn't work on phones etc... There is no right and wrong here, there is just: test it and see if it works!

i'd like to have a REAL technical discussion with these people here that are so-called experts... Because their arguments (excusez-le-mot) SUCK.

so please adapt your first post, because what they are saying is just guessing and not based on experiments nor experience, which renders it completely useless

Just my 2 cents

discussion is worthless, you can't convince me with some "maybe this, possibly that", if you say it's useless: give hard numbers or (sorry, but...) stfu!
