ardatdat - any plans for updating git repo? (as far as I can see - last commit is from 2011-01-18)

Since Tzbob seems to been gone for good (or went for deep, winter sleep ;) ) - I wanted to sneak peek your changes, if there is a way to use OC in Uruk kernels... Perhaps you could prepare patches for plain 2.6.29? Of course if you are willing to do so :) (I've simply done most of installer and tuning work - and I could look toward OC stuff).
[Gen8 Android Development] woti23:

Does OC kernel affect on UI somehow, sometimes? I've backported ardatdat changes to my kernel, it's working (but I can't be sure I haven't forgot something) but media player "movie list" is smudging while scrolling - rest seems to be ok.

Looking at statistics somehow system/governor does not like 1,1GHz frequency too much - it goes mostly up to 1,2Ghz.

If you don't mind ardatdat - I would like to prepare package with OC kernel for UrukDroid 0.7 (not the default one - unless not for now).
[Gen8 Android Development] topifone:
I try other launcher (ADW Launcher EX) and it works well. The same with UrukDroid 0.6 So I think the problem is LauncherPro 0.8.3?
[Gen8 Android Development] ardatdat:
^^ Of course, my kernel is put to github for open source sharing and it provides all of us to share our findings and tuning to make a better kernel/rom.

Thanks aur0n for your great work and of coz you can include the useful part of the OC kernel in UrukDroid. It will be good if you could share with us on how to further fine tune the kernel if you have made any for the future Uruk rom :)
[Gen8 Android Development] woti23:
thank you too for setting up the github!

btw: i may have overlooked something in the config, but i find no values in sysfs for the current flow. should have to do something with the regulator, i2c.

appearantly current widget app doesn't work though - any idea?
[Gen8 Android Development] $aur0n:
I can put source - but there is nothing special in it - just some patches from compcache,ext4,fs-cache,nfs4,interactive cpu gov (probably I haven't missed anything). Config is since Uruk 0.4 (or something) compiled in - so everyone can take a look :)

I've added changes from your OC, mostly overwritten arch/arm and some linux/ stuff that was missing. But there is something wrong with disk (nand memory) access - I as unable to write properly file over ssh to disk (md5sums ware different each time). To /tmp (witch is RAM) it looked ok... any idea what am I missing?
[Gen8 Android Development] tiki1217:
I have installed the OC kernel two days ago. And today I found that my files app loss the network founction . I try to reboot , re-start wifi etc... But it is still no network founction.

Can anyone help me ?

Hi!

Litlle issue with booting up the 101.

I followed instructions, but when finally choosing Developper Edition the device is frozen on the Archos screen.

Any idea?
[Gen8 Android Development] nimrodity:
i use the 0.7rc2 OC Kernel since it came out,everything is fast,with the kernel and 0.7 the archos is faster than it ever was.

Great work $auron
[Gen8 Android Development] Bingoig11:
Nothing to do...

Tried to reinstall Zimage and initramfs, it don't want to boot up in Developper Edition...

Any help would be appreciated :D
[Gen8 Android Development] Pierreken:
I followed the procedure, went into the developer menu and flashed the 2 files but now my device is in a reboot loop. Can not get it to boot at all.

I used the advanced installation procedure (install on internal storage).
[Gen8 Android Development] Windkracht13:
With the latest kernel overclock, Youtube will stop. The picture freezes.

When I put setcpu at 1000MHz, the picture is as expected.

Do you also suffer from??

Sorry for my bad english ...
[Gen8 Android Development] jpeishen:
I've tried the method provided above however I couldn't boot from the developer's edition. It just froze.....

I have a A101IT 16GB. Can anyone confirm that A101IT can actually be oc to 1.2ghz with firmware 2.1.08?

Thanks
[Gen8 Android Development] cdelta01:
Yes it can. You can use the kernel in the OP. Separately if you are using the UrukDroid 0.7, $aur0n also has an adapted version of the kernel for overclock to 1.2ghz.
[Gen8 Android Development] Kashban:
I would rather say "it depends". Mine can't (8GiByte version). It becomes unstable after running some time.
[Gen8 Android Development] jpeishen:
I did use the OP kernel but after flashing them I cn't boot using the Developer's Edition.

:(
[Gen8 Android Development] saprano614:
any word on a update to work with new FW
[Gen8 Android Development] ardatdat:
Just a quick reply: I am working on the new kernel for the new firmware. Will be out very soon :D
[Gen8 Android Development] spicy_puerto_rican:
Chulri's Permanent Root using the 2.3.20 initramfs + the zImage from this thread work

Yes, you heard right! Chulri's Permanent Root access using the updated Firmware's 2.3.20 initramfs + the zImage from this thread works!

My Steps:

- I did a full, permanent root using Firmware 2.3.20 AND the permanent initramfs + zImage for the same 2.3.20 Firmware (by way of Chulri's method).

- I created 2 temporary folders on my laptop; 1 folder to copy ONLY the initramfs file from Chulri's method and the 2nd folder to copy ONLY the zImage from this thread.

- I moved BOTH seperated files into 1 single folder.

- I then went back to my Developer's Edition and reflashed BOTH files from the last single folder that contained the initramfs from Chulri and the zImage from this thread.

So now, I'm currently using the new Firmware 2.3.20 with full, permanent root access WITH 1.2GHz as my SetCPU speed with absolutely NO problems whatsoever!! :cool::D

(I have the A101IT & this post was sent from it).
[Gen8 Android Development] chrulri:
Great work guys!:cool:
[Gen8 Android Development] ardatdat:
New kernel updated in post #1 for the newest firmware :cool:
[Gen8 Android Development] lagoskon:
Thanks a lot for your work, again
[Gen8 Android Development] EP2008:
Can someone explain what "(max 1.2G)" means? Is this app storage space, because it hasn't changed for me when I flash according to instructions.

Thanks in advance.
[Gen8 Android Development] IGstarr:
it the cpu 1200 Mhz ;)
[Gen8 Android Development] EP2008:
Ah, thanks! I was really hoping it was app storage space - speed isn't an issue on my device, but space is :(
[Gen8 Android Development] IGstarr:
and again the overclock kernel dont work for me ( i had the same problem on fw 2.1.08) :mad: i do a fw update to 2.3.20,copy initramfs from avos_2.3.20_sysroot/(avos_2.3.20_tmproot second attempt ) and copy zImage from zImage_archos_2.3.20_recode09 flash all in SDE and reboot and the tablet freeze on the bootscreen so what i do wrong? i have a a101ti

btw avos_2.3.20_sysroot by itself works for me
[Gen8 Android Development] lagoskon:
try both files from ardatdat zip file. It has chulri's initframs already.
[Gen8 Android Development] IGstarr:
still no luck freeze on bootscreen :confused:
[Gen8 Android Development] neldoreth:
I try too, and it freeze for me too.

What are we do wrong?
[Gen8 Android Development] ardatdat:
If this is the case, maybe this kernel is not compatible with your machine (most likely A101?). Then, use back chulri's kernel should be fine :)
[Gen8 Android Development] neldoreth:
I try it again. I have Archos 70 IT.

I enter in SDE and format ALL, then install 2.3.20, reinstall SDE and flash you kernel with chulri's stuff, and now start sistem, icons in the home but sistem restarts. Any body works fine ?
[Gen8 Android Development] SWFlyerUK:
Hi Guys,

So I have the Overclock and Rooted Kernel latest in the first thread, though when I set the frequency to 1200Mhz in SetCPU my system is very laggy, and infact worse, so when I put the max and min back to 1000mhz it runs perfectly, only when one slide is set to 1200mhz that I have the issue.

Any ideas please?

Regards.
[Gen8 Android Development] jpeishen:
I was able to use the kernel plus the churi's temproot initframs to boot however, if i set the freq to 1.2g system would freeze........ Archos won't boot if I use Churi's sysroot initframs. :(
[Gen8 Android Development] fzelle:
It's probably the same problem all overclockers on ARM Devices have.

When increasing the clockrate you also have to increase the vsel so the proc has more oompf.

And the vsel at which a system is running well is unfortunately not the same even on the "same" product.

Just take a look into the Milestone/Droid Threads, there are alot of posts with this problem.

On the Milestine/Droid they resolved it by doing OC with a textfile where next to the frequencys they have the corresponding vsel.

This way everyone can optimize his system.
[Gen8 Android Development] chaien78:
Please help.

I followed the instruction strictly at 1st page, installed SDE (2.3.20, Android 2.2.1, boot version: unknown / 4.04.000000) then downloaded "avos_2.3.20_tmproot" and "zImage_archos_2.3.20_recode09". At step 5, I copied initramfs from (avos_2.3.20_tmproot) and copied zImage from (zImage_archos_2.3.20_recode09) to Archos machine BUT notice

"Kernel (zImage) not found"

. Any mistake? :confused::confused:
[Gen8 Android Development] jknut:
For the new 2.3.26 fw, does there need to be an update? Thanks!
[Gen8 Android Development] jakkrith:
Thank you again and waiting your kernel for fw 2.3.26 :D
[Gen8 Android Development] wangsiyu:
It's strange that zImage for old firmwares aren't compatible on 2.3.26fw,so I have to wait.Brothers In Army 2 may run smoothly at least 1.2GHz frequency.
[Gen8 Android Development] Infinity123:
Are you working on a new OC kernel for FW 2.3.26 (im waiting for it:))?
[Gen8 Android Development] LeoNg628:
lol...he already buy A500...so sad:o
[Gen8 Android Development] spino1970:

[Gen8 Android Development] alexdk:
Hej all

Can I use this kernel on my A70IT- 2.3.26( android2.2.1)?

:confused:
[Gen8 Android Development] spino1970:
I would like to know the same...
[Gen8 Android Development] DavidDivadman:
To: alexdk and spino1970

Hi,

I tried this to overclock to 1.2Ghz my Archos 101 IT firmware v2.3.26 (the latest to date) and the Archos keep rebooting after the Archos logo ;-( So I don't think it is working on this firmware for now...
[Gen8 Android Development] jazux:
Hi, I'm thinking of buying one of these :-) but I don't understand.... in threads topic it says "2.3.x firmware ok" so does it mean gingerbread?
[Gen8 Android Development] msticninja:
No. 2.3.26 is the version of the Archos firmware. The Android version is 2.2. If you want to research buying an Archos Gen8, look over in the general forum, not development. The only thing in here is Urukdroid, the only custom firmware currently available for Archos Gen8, and other projects which are still in their infancy.
[Gen8 Android Development] AlaskaPardus:
Same here....bootloop and nothing else :(
[Gen8 Android Development] unixwise:
Hey Buddy, it can only show 1000Mhz on setCPU, anything went wrong ?
[Gen8 Android Development] ardatdat:
Hi everybody.

Although I have bought Acer A500, I am pleased to continue support the archos kernel here. The problem is that my machine has been 'kidnapped' by my friend and I need it to test the kernel.

In addition, my work is keeping me busy to die so I leave all android related development untouched for over a week :(

When I get my machine back and have more time, I will keep up with the newest kernel and update all of you here :cool: Cheers!
[Gen8 Android Development] lagoskon:
Very Happy News. We will wait your next OC !! Thanks
[Gen8 Android Development] pki101:
Removed Ubuntu 1.0 because it was not so stable and installed this version. Looks good and this is better, because all non-root side software is working also in root-side..

But would like to boot in root, without selecting developer version every time.. is there fix for it??
[Gen8 Android Development] arpruss:
Is there a version of this that works with 2.3.26 fw?
[Gen8 Android Development] spino1970:
Still not... :(
[Gen8 Android Development] msticninja:
The only way to boot into Dev automatically is to choose Remove Android in the Boot Menu. You will not be able to boot into the stock FW anymore though.
[Gen8 Android Development] msticninja:
Ardatdat doesn't develop for the Gen8 anymore, so unless someone can crawl through his git and figure out the problem, there won't be any development on this kernel.
[Gen8 Android Development] arpruss:
I really don't know much about overclocking, so this may be a dumb question. It wouldn't be enough to take the latest official stock kernel source and just change omap3630_mpu_rate_table and omap3630_dsp_rate_table to the ardatdat kernel's last stable version?
[Gen8 Android Development] msticninja:
I really don't either. I know that's part of it, but if you look at his git, there's notation everywhere about changes he's made, but no description of reason or outcome. I really can't tell which changes were related to overclocking and which weren't.
[Gen8 Android Development] arpruss:
How badly can you screw up your device if it doesn't work?
[Gen8 Android Development] 2ShedsJackson:
Are the configs for these kernels posted somewhere?

I searched through the 30+ pages of posts in this thread and only found links to binary images.
[Gen8 Android Development] guitarist5122:
this oc kernel doesnt work with 2.4.19 does it?
[Gen8 Android Development] sibere:
obviously, you know that kernels posted here are for UrukDroid and not for the stock firmware, right?

If you want kernel updates (undervolt, overclock, latest patches, etc) you must go to urukdroid dev thread. $aur0n and I have posted some kernels.

you cannot change stock firmware kernel !
[Gen8 Android Development] arpruss:
Surely you can. I use a custom kernel that tweaks the mmc timeout settings.
[Gen8 Android Development] sibere:
How did you flash this kernel over the stock one?

Flashing a kernel via SDE is not flashing the kernel used by the stock FW but by the dev edition (AKA urukdroid or any other installed OS like ubuntu)
[Gen8 Android Development] arpruss:
If you install the chulri rw root, then a copy of Android sits in the dev edition slot, and you can change its kernel. And then you can delete the original Android and boot straight into the modified one.
[Gen8 Android Development] sibere:
Ho I see. Then It's not what I call the "stock" firmware ;)

A bit of misunderstanding here, sorry. For me, stock means on the read only file system.

Well it's then pretty much like running urukdroid, isn't it? Except that it is 100% stock.

BTW I posted recently a kernel build from the very latest sources update from archos (commit on the 29th of August). It is undervolted, overclocked, USB patched.

It is available here. It should be compatible with latest firmware. Maybe you can give it a try?
[Gen8 Android Development] devwithzachary:
I know its a bit late and you might already know this but this dosnt seem to boot with 'stock' android i shows the urukdroid logo and says boot error, does anyone know of a oc kernel for stock android install in the developer section?
[Gen8 Android Development] SWFlyerUK:
Does this not work with the latest firmware, just hangs at the boot menu when using chulri's inframs (Perm root) and your zimage?

Shame as I was looking forward to trying it today.
[Gen8 Android Development] toxicstone:
I was flashing the archos 101 IT.

0) Install SDE first

1) Download chulri's initramfs from here: http://code.google.com/p/archos-gen8...downloads/list

(Download the appropriate version that matches with your firmware version)

2) Grap the newest overclock kernel: http://www.mediafire.com/?pnbev44hk2m1346

3) Reboot your Archos holding "Volume -"

4) Recovery System -> Developer Edition Menu -> Flash Kernel and Initramfs

5) Connect USB and copy initramfs from (e.g. avos_2.X.XX_temproot.zip) and copy zImage from (e.g. zImage_archos_recode04A.zip) to Archos machine

6) Reboot by holding "Volume -"

7) Choose the 2nd menu item (Developer Edition)

8) Here, you get rooted in the newest firmware + overclock kernel

9) Enjoy ^_^

0) I did

1) I downloaded but didnt use cause 2) has same filenames (not size)

2) As i said

3) I did

4) I did

5) I did

6) I did

7) I did

8) Didnt happen

9) Ehm no.

It didnt get rooted nor optimized, atleast what i know, i cant see but i didt not

ice any perfomence, only thing i notice was that some games didnt work like gun bros, clouds&sheeps , the games starts and its ok but when i start a mission is when the games close (not force close) just close.

I dont understand why Zimage file and initramfs.cpio is in both first and second link.

Use 2.4.8 firmware stock

Hope for some help.
[Gen8 Android Development] cwkchan:
Hi,

Does it works for 2.4.81? Thanks~~

[Gen8 Android Development] stanglx:
See my previous post...

But every CPU is different.. Even though the CPU supposedly can go up to 1.2 Ghz, Archos most likely did not deploy the proper power management AND/OR voltage to support higher clock rates. Some CPUs will work fine some will not... Every CPU has a thermal and power tolerance + and -.

If you want to get this stable for everyone you need to increase voltage either at the mini or micro levels... This still may not have a positive effect as it could also be lack of voltage being supplied to the chipset or memory controller. You also need to see by increasing the clock rate are you increasing FSB frequency or memory frequency.. Im not familiar with ARM architecture but this also needs to be taken into account.
[Gen8 Android Development] ardatdat:
If you look into the original source code, you can see that it already increase the voltage for the 1200 frequency. It is already set here and there is a frequency table that will tell the system how many voltage to give at what frequency.

Actually, I have been modifying the Nexus One kernel for a few months and of coz I have taken into consideration of the voltage increment. Thanks for prompting.
[Gen8 Android Development] Tzbob:
I have run across another speedbump using this kernel, it seems that everything works perfectly for me but the Video Player from Archos doesn't work.

With the cpu at 1Ghz with this kernel i still have this issue, anyone else?

UPDATE: after reflashing with this kernel the player works again when the CPU is at 1GHz, however it doesn't when it's at 1.1GHz.

Mine peaks at 2136 (1000 MHz, ext4), but most of the time I get something around 1950.

Still wondering why the planet bench is so slow compared to the desire (40+ fps) and why the moon has black triangle errors.

In comparison my htc desire (@1152 MHz and a2sd+ on ext3):

Quadrant: 1480 (at best)

File writes are incredibly slow on the desire, while it is five times as fast with the planet bench (and without errors)

Linpack: 33700 MFLOPS (more than 2x the performance of the Archos)

An3DBench: 5918

RL Benchmark SQL Lite Performance: 195,569 (almost twice as long!)

Interesting numbers... You see a nice boost in CPU, I/O, 2d and 3d just by adding 100Mhz. That leads me to believe that this sucker is truly CPU bound with a ton of room for the other components... What it also tells me since memory did not change the memory clock is not bound by the CPU clock. What is also says is that added memory would not help nor would faster memory would help - at least for the non-memory operations... and at least for this test.

Is there a way to overclock the Video clock or is locked to the CPU clock rate?

Any one else have the same problem?
