Comment by savalentini:

Hey Poly, does this new kernel has the 200 line modification everybody is
talking about at XDA? I think it's called "automated per session task
groups v4 (CFS)"

Pershoot and Wildmonks have implemented it on their kernels and I've only
heard wonders about it.

this list is getting shorter and shorter by the minute.

Great work Polytheus

Comment by Tetsuo6995:

Are you speaking about the kernel patch that Linus Torvald was getting
crazy about ?

I saw some compartive tests on Ubuntu but din't knew people already ported
that to Android !
That would be totally awesome !

Comment by pixhelado:

The modification of 200 lines can be implemented in the bashrc as shown on
this website http://www.tuxapuntes.com/drupal/node/1956

@pixhelado
I just a play this on my ubuntu that i have on a old pc, and notice grate
changes on gui response.

Very nice hack.

This simple hack can be made on the base release?

[open...@googlecode.com]

Comment by pixhelado:

Probably yes, I think they are doing tests to implement a distribution
base. tonight im going to do tests with the new kernel when I get home,
probably we can get more speed in our android desktops

[open...@googlecode.com]

Comment by Tetsuo6995:

Yeah, this patch if i'm not wrong, greatly enhance the way things are
queued for the CPU.

That means no more laagy home when some heavy app is running in the
background.
But well i still wait to see that working on an android device...

Latest news on XDA about this patch implementation.

Apparently someone tweaked the patch to be more useful on the Android
Kernels.
Replacing the "TTY aspect" by activities.

Comment by savalentini:

I have a nexus one with cyanogenmod and wildmonks kernel, the patch was
implemented a couple of weeks ago and made a huge difference on how smooth
the phone works. Implementing the patch should give us more speed when
moving through home screens and many other noticeable improvements.

Comment by vu.thaianh1510:

very good, event an iphone 2g have a 400MHz CPU, it is very fast, because
of the way of coding of apple, i hope this patch will implementing
something on android speed!

Can one find the exact location of the modified "automated per session task
groups v4 (CFS)" patch?

Could it be that :

Not sure it's the correct version of the patch :(

Comment by cmgonzalez:

Look here:
http://review.cyanogenmod.com/#change,417

Patch Set 1: Abandoned

does nothing good, tested with 2.6.35.7 and .8 kernels barely shows
improvement. Tested on a clean build again.

Comment by vu.thaianh1510:

hi polytheus, does systemV6.1-rc5.zip 2.6.35 kernel?

[open...@googlecode.com]

Comment by polytheus:

No, but all development has shifted to 2.6.35 and it will be in the next
release.

Comment by vu.thaianh1510:

i think so, too, and that's a good news for me,

Comment by richardaburton:

> The powerbutton is connected to gpio 76?

Yes, according to the service manual

> GPIO 58 has something todo with gps?

Enables the low noise amplifier, again according to the service manual. I
would assume this should be on when the GPS is on and off when it's not. I
don't imagine it's any more conditional than that.

[open...@googlecode.com]

Comment by polytheus:

There is no reference to gpio 58 in our kernel (as far as I know), so
either that is handled by the AMSS or we should try to enable it and see
what happens :-)

The power button thing just is a notice for me, maybe I can simpliy the
handling of the power button a bit, as we currently ask for it's status by
rpc.

Comment by savalentini:

Lot of progress lately! thanks to Polytheus and everybody else who's
working on the rom, specially on the kernel update.

Comment by ivolucas:

Hi Polytheus,
Do FM radio works in the new kernel?
I am asking that because i don't sew it refer in the list.

Tanks, an keep the good work.

[open...@googlecode.com]

Comment by s2ada31:

Hello. But, if I may say so, Where are you exactly on this new kernel? It
is still relevant?
(Sorry for my english, i'm french)

[open...@googlecode.com]

Comment by polytheus:

The status on the wiki page is up-to-date. Current show stoppers are
non-working Camera and bluetooth. Additionally userspace has to be changed
for the new sensors interface.
But most importantly, the new kernel drains battery as hell (maybe related
http://code.google.com/p/cyanogenmod/issues/detail?id=2189), (7 hours till
empty when you don't touch it), so its barely releasable. The source for
the kernel is already in our repo, so feel free to fix the remaining
bugs :-)

We have to edit config file to utilize that is already
in ./drivers/misc/akm8973.c file.
For reference, ./drivers/input/misc/akm8973.c file is unstable.

Yes, I knew how to choose the file we use. But do both files provides the

I've installed 17/01 nightly build and battery is working well: do you
resolved draining issue? Otherwise could be helpful to give you any
information about my phone "configuration"? Thank you very much for your
great work.

Comment by GiorgioM...@gmail.com:

@parthago: interesting, but they're keeping their source closed and
probably our phone is not powerful enough to run sense.

well if we look into some old models like htc tatoo its same spec and i am
looking into codes.

Comment by ivolu...@gmail.com:

Hi to all,

Polytheus, what you think of adding swap suport to the new kernel.

[open...@googlecode.com]

Comment by tenchian...@gmail.com:

yes please add swap support.
And i want the support of the btrfs filesystem too.
Ok juste the swap it's a good start...

[Tiago Mota Freitas]

New features should follow the issue tracking system.

Please add issues for the enhancements you would like to have implemented.

Please add a justification for each issue you submit.

Don't just say "I want the support of btrfs.".

[open...@googlecode.com]

Comment by GiorgioM...@gmail.com:

@tenchian what do you need btrfs support for? Sdcard maybe?

[open...@googlecode.com]

Comment by tenchian...@gmail.com:

Yes btrfs roxx on my sdcard for data2sd, i get 500 more points with btrfs
than ext 3 on my htc desire (total quadrant score on my desire : 2890 ^^),
i want to know if it's the same performance increase on gw620.
