Definitely something wrong with test 12. I just rebooted about 20 mins ago and then I went into setcpu and found out that for most of the time, it stayed at the max frequency. Was using savagedzen. For those who find that it becomes suddenly too smooth to be true, I urge u to check the time spent at each CPU speed because for all u know you may be running at maximum frequency throughout and the tab might heat up real quick. Might be dangerous man.
[Eee Pad Transformer Android Development] gkillerx:
Just wanted to check this, and indeed, when I selected savagedzen bam reboot. Same goes for lulzactive. Back to ondemand.

If anyone is wondering what these things do. Check this out:

http://xdaforums.com/showthread.php?t=1443731

edit:

I can't select ondemand anymore. As soon as I select ondemand, bam black screen and reboot. already wipe cache and dalvik. OC1500
[Eee Pad Transformer Android Development] j3tt3:
Though I am not an expert, but I will tell you what I usually do..

Backup using cwm

Wipe (cache, dalvik cache)

Reboot

Flash guevor's kernel test10 (to start)

Do some test (like Antutu or Quadrant)

If ok, you can increase frequency or Flash to latest kernel (test12c)...

I never had any reboots during normal use using this steps though most people does not advise wiping cache & dalvik cache when installing kernel. I had reboots only during testing (i.e increasing the frequency to 1704mhz)

You can read more in forums or somebody else wishes to correct how to properly install kernel although this works well with my B80.
[Eee Pad Transformer Android Development] karapoutsoglou:
v.12 is problematic.i have reboots,lags,games dont play well...

in v11 everything was extraordinary.
[Eee Pad Transformer Android Development] igot6strings:
I pretty much have the exact same comment.

12b not working so well.11b work amazingly well.
[Eee Pad Transformer Android Development] GrijzeGeest:
Tried the oc1200 for a while, both with setcpu and CPU master pro. Seems to work for the most part (after erasing cache and dalvik cache) but makes the browser unstable: crashes and freezes.

installed the 1200 kernel and max was 1200MHz, but after a reboot it only clocks at 1000MHz max according to cpuspy

Will you add support/compatibility for AOSP roms? Thanks.
[Eee Pad Transformer Android Development] Caramel:
Little feedback after one day, no freeze, no reboot, wifi and BT are OK

Using no-frills Min 456 Max 1200 Governor On Demand /Noop on ARHD 3.1.0

Something strange, when i submit my poor 5533 antutu score :D i found a Transformer under ICS O/C at 1592 :eek:
[Eee Pad Transformer Android Development] j3tt3:
After one day, I have no reboots,battery drain nor sods even switching from stock to arhd to revolver. 1.2mhz is stable on my TF.

Next level pleaze... 1.4 or1.5mhz
[Eee Pad Transformer Android Development] SiNJiN76:
Just tried this about 30 minutes ago. OC version. Hot Reboot. While reading email. FYI...my TF is stable up to 1.544 or so.
[Eee Pad Transformer Android Development] AllanJacques:
For me it is a no-go, as far as I flash this kernel TF hangs at asus screen, if I manage to turn it off and on again it boots but hangs as soon as system loads...
[Eee Pad Transformer Android Development] scottyf79:
Try wiping cache and dalvik before flashing the kernel.
[Eee Pad Transformer Android Development] kevonomics:
I'm going to try wiping caches because when I flash the kernel SetCpu nor Voltage Control show me the possibility to clock it at 1200 mhz.

I currently have that bootloop CWM problem that I should fix through ADB.. So I cold linux boot it after flashing. That could be it.

What app are you guys using? Any other way to fix bootloop without ADB, I am not around any free using computers most of the day to fix it.
[Eee Pad Transformer Android Development] Danzano:
Lol was the nickname danzano with a picture of auckland city if so that was me the other day testing blades kernel but had to go back to stock after random reboots :D

[Eee Pad Transformer Android Development] guevor:
I have updated the first post with a new test version.

Also created a github repository.

The new version can be overclocked upto 1640.

I also increased the voltages a bit, because they were too low and could cause instability.

The problem with frecuency limits was also solved, thanks to Roach2010 fix.

I'm thinking of adding another version that boot with the upper limit to 1.4Ghz and the min at 456Mhz and using ondemand to test if is more stable as Caramel suggests.
[Eee Pad Transformer Android Development] psyk974:
Compatible with cyanogenmod?
[Eee Pad Transformer Android Development] msticninja:
Lmao. We must have been working on this at the exact same time. I'm looking at your github, and it says we both pushed our last commits exactly an hour ago. Nice work, nice work. :)
[Eee Pad Transformer Android Development] guevor:
I can not say because I have only tested with Revolver, but some previous comments indicated that on AOSP roms failed things like wifi.

Best two people doing something interesting that none.

On Monday I did a lot of tests and traced the problem to cpufreq.c, but today when I came to have time to do more test, I looked before other cpufreq.c versions and found Roach2010, he did it before.

I updated the first post with a test3. The previous version has bad 3d clock that caused bad 3d performance, sorry.
[Eee Pad Transformer Android Development] msticninja:
I agree. Two interested, but probably tired, people.

Same timeline for me. Started working on it on monday, then I saw Roach update his git, so I started over with a merge from his ics branch.

Good luck, I'll keep an eye on your dev. I probably won't be doing a lot in the next few days, but feel free to fork my git or pull changes if you see something you like. Not much changed yet, though.
[Eee Pad Transformer Android Development] SWEagle:
That would be great :D but don't forget to low the voltages of the 456Mhz to the lowest as you can... or, as i requested earlier, leave us the option of managing our mV...

I've been using the 1.2Ghz since it came out. Great Kernel. No reboots and i think Wi-Fi is more stable...

Thanks
[Eee Pad Transformer Android Development] hachamacha:
Nice job. Thanks for taking this on and setting up git for the changes.

I've had ICS on since it arrived, and for whatever reason haven't been unlucky with it, so haven't had a crash yet (~3-4 weeks).

I just tried your test3 kernel, only for the last hour using 1.2G as default + interactive gov and a few profiles. It seems solid to me at this speed. I think my box can only manage ~1.5 but to spare the battery I'll keep it here.

Another thing I like is that this is the first batch of modules I've seen built for ICS that seem to all work properly. I'm sure someone has done that before but they've caused me troubles till now.

Thanks again - Hashi

PS: Eventually I suppose ICS will start crashing for me like everyone else, so will report back if so.
[Eee Pad Transformer Android Development] finalhit:
you guys should always post which rom you're on whenever you're making a comment about the kernel. it helps the devs debug and everyone else when picking which kernel to install.

i was having performance issues with 12. currently on stock rooted rom.

on 11b, when i scroll down an image heavy webpage, it renders the low-quality (jaggedy) version, then quickly smooths out the normal-quality version.

on 12, i typically see empty portions of the page, then it slowly renders the low quality version, then slowly follows up with the normal quality.
[Eee Pad Transformer Android Development] igot6strings:
True enough.

I'm on revolver. Used the voltages in op, OC profiles in CPU master are 1200 on battery, 1400 when charging, 1000 when screen off. Ondemand for the most part, sio for io.
[Eee Pad Transformer Android Development] guevor:
Ok, test12 seems to be bad. Tomorrow will try to fix it and if that is not posible, continue from test11 and discard the new governors or may be create a new one.
[Eee Pad Transformer Android Development] weazil60:
Test 12 C

Evening all. I am on revolver 4. All previous test kernels have been fine, however test12c gets stuck in a boot loop.

Checksums are fine also.

Thanks for the superb work being carried out here.
[Eee Pad Transformer Android Development] thenewguy821:
Running 12b on Rooted Stock ROM, OC to 1400, SavagedZen, SIO and used PimpmyCPU to undervolt -150 across the board. I have had no problems, all day.

*edit* After re-reading the first changelog for 12c, should I change to that, or should 12b be ok?

*re-edit* Undervolting -150 made a big hit on benchmarking. Changed to -125 and scores JUMPED.
[Eee Pad Transformer Android Development] j3tt3:
test12c @ 1640mhz interactive on Revolver Beta

12c on frozn wifi problems and running a little warm in hand's I appreciate your work and keep it up thanks so much.
[Eee Pad Transformer Android Development] Caramel:
Hi

Running 12c on ARHD 3.1.0, work fine, but less smooth than 11b
[Eee Pad Transformer Android Development] guevor:
I'm working hard on test13. The new governors of test12 results on exposing certain problems.

Trying to solve that problems, I finished again by changing fundamental parts of the system, representing a change in the way of changing the frequency of the processor, how to "rest" of the processor when not in use, and most important/difficult/problematic, how suspending the tablet.

This last is where I'm now, because right now does not work well. Do not know how long will it take, even if I will get to it, or if instead I have to discard it.

For now, the recommendation would be remain with test11b.

EDIT:

It seems near. Fixed camera initialization problem , solved restoration of the voltage regulator problem, apparently remains only minor problems. Now to eat and I trust that tonight will be ready.

I hope that the effort was worth it, and the result will be better and more stable.

Does anybody else have problems with app compatibility? I have a TF101G on Megatron 1.0.1, everything is buttery smooth and I love your kernel, it's the only one that doesn't make my tab reboot whenever it tries to enter deepsleep, but I have noticed that Modern Combat 3 (which I have restored from my phone Titanium backup) crashes after the Gameloft Montreal logo and today Google Goggles wouldn't install... It works on stock kernel though.

Still great work you did there, it's rockstable for me! :D
[Eee Pad Transformer Android Development] guevor:
Test13

That's a big change.

You may not notice, it may not solve anything, but certainly the change is quite large and I have hopes that it will have served to improve stability.

Time will tell.

There are also changes to make 3G work on CM9 (thanks ricardopvz), can someone confirm it?.

Another change is that now tun is modular, I mean, there is a module tun.ko as gunz.jones asked, can you confirm it works well?, I appreciate it.

I also hope that someone with xbox pad working, send me the file /proc/config.gz of a working kernel.
[Eee Pad Transformer Android Development] guevor:
Can you try Test13 and report how smooth is?, better than 12? better than 11?

Thanks

Test12 has problems. Please try Test13 and report. Thanks

That strange. Test12c has changes on frequency and voltage, but to increment it, that should be more stable. Can you try Test13 that has the same frequencies/voltages and report if this work.

That's the first notice I have of a app compatibility problem caused by a kernel. I will investigate it.

OblMe

With the prepaid sim card of Base Belgium 3G is working fine as before.

But wit the dutch KPN prepaid sim card still problems due too the default APN name cann't changed which is required for this sim. This is not a kernel problem may be a problem of Megatron 1.0.1 build
[Eee Pad Transformer Android Development] artnat:
Kernel 13 working like a charm @1.4 with Megatron 1.0.1! Great job! 1.5 still causes freezes and reboots but 1.4 seems stable - I ran stress test with Set CPU with no problems.

Running Revolution HD here on 1.5 and ondemand. It's feeling smoother then 12. but hard to tell. Will test futher.

running for 1:10:44 and 53 is she sleeping :) thanks!

Edit

Is it me or is multitaking much better ?
[Eee Pad Transformer Android Development] j3tt3:
no reboot but it hungs at 1640, seems stable at 1500 on my tf, will do another test in diff freqs
[Eee Pad Transformer Android Development] SWEagle:
Yes, the smoothness returned with this 13 version Kernel... vs 12x Kernel...

The stability, only time will tell ;)
[Eee Pad Transformer Android Development] GrijzeGeest:
Agreed, feels very smooth, and I just came from 11b
[Eee Pad Transformer Android Development] DammedKiller:
Well, I´m trying test 13 and is fairly smooth, anyway I didn´t notice that test 12 was less smoother.

Hope that reboots will be fixed now.

I´m really fascinated by your speed of updates. Good work guevor!
[Eee Pad Transformer Android Development] cmarticus:
Just installed 13 was on 12c for 24 hours with no issues. @1.4 12c got 6600 antutu 13 got 6489.

Evening all, I am on revolver 4 with test 13, however I have no wifi. Test 11b was the last good kernel.

Thanks.
[Eee Pad Transformer Android Development] tinnef:
Revolver is the problem. I'm on AOKP with test 13 and have no problem with wifi at all.
[Eee Pad Transformer Android Development] habylab:
But the governors have gone now? Could we have them back please.

Also, is it possible you could look into sound loss issues on ICS? Is that at all kernel related? Thanks.
[Eee Pad Transformer Android Development] ricardopvz:
guevor, can you add tun support?

Stock kernel has it, this one doesn't.
[Eee Pad Transformer Android Development] msticninja:
It's killing me wondering what you changed in v13 to fix the suspend function. ;) I'm trying to rewrite clk_disable_locked in clocks.c, but it takes so long to get a reboot or SOD, I can't even tell if I'm making a difference. :D
[Eee Pad Transformer Android Development] DROITURK182:
went back to v11b

I went back to v11b from flashing v13 I had a major problem with the tablet wanting to power off or just not wanting to wake up from sleep, I would push power button and tablet wouldn't turn on or come out of sleep, I would have to hard reboot the tablet. I'm on stock, rooted and now running v11b kernel from nandroid backup, before flashing I wiped cache and flashed new kernel. If I did anything wrong please reply and let me know what I did wrong.
[Eee Pad Transformer Android Development] Danzano:
Great to see the progress you are making :D

I noticed you added a new frequency I know it sounds stupid but my tablet always sat nicely on 1.59 but will not sit nicely on 1.6 and gets ocasional reboots. Would you be able to add the frequency 1.59 please??
[Eee Pad Transformer Android Development] igot6strings:
13. Holy shindiggies she's quick.

[Eee Pad Transformer Android Development] dgcruzing:
Goes to show how different chipsets react.

I am on the same setup..

Flashed 13..been running for an hour @ 1600..

I am tethered at moment.. Turned it to sleep.. Waited for 10 seconds.. It woke no drama..

Will keep running tests and let you know..

So far all good..

Edit.. 5 hours later..

Plugged into dock... Shut its self off.

On reboot problems hooking back into teether..

Had to wipe teether.. Turn wifi off then on a few times..

Before connecting, Also noticed now that it's connected its not going blue

Know I am as can write this.. Seems to be taking about 10 minutes to turn blue..

Will check wifi once back to hotel..

If problems persist, it might be back to 11b for me

As that seemed to play nice with my tab..
[Eee Pad Transformer Android Development] j3tt3:
test13... i set freq to 1504 but automatically goes to the previous 1640...

kept as is and ran Antutu (7445) and Quadrant (3650) - did not hung,

deep sleep is working fine...

seems going smooth ...

now have to check battery life...
[Eee Pad Transformer Android Development] chatch15117:
Your kernels are sex. I wish you health and prosperity.
[Eee Pad Transformer Android Development] guevor:
I'm on Revolver and wifi work for me. Have you tried to switch it off and on?

They were problematic and prefer to isolate the testing of changes from governors problems. May be on future.

Sound loss? I have the intention of look at sound but not sure what problem are you refering.

I have made it modular to make test, but if that is a problem can go back.

I know, it's so unpredictable. I can't say it's solved, but may be we are on the right direction. About my changes, now i'm not on my computer, but later will update the repository.

What frequencies are you using. Test13 have diferent frequency/voltage tables, may be the new one were worst.

Will look at it, but i'm not sure the last table change were for good, seems like people has more problems with overclocking.

I have not changed anything directly on the wifi code, but can't say it's not afected by other changes.

About the blue wifi icon for indicating conection was related to connecting to google and sometimes it was grey but working. Simply there are problems with connection to google.

For me, at 1.2Ghz, all night with wifi on, remains good and smooth, 15 hours uptime, 11 hours deep sleep and on the 8 hours of night with wifi 4% battery used.
[Eee Pad Transformer Android Development] Danzano:
Thanks for the quick reply I always used that setting in hc and always wondered why it was a miss in icys lol

Would be great if it can be done without ill effects to other people overclocking

What caused the new frequency to make trouble for some? Was it the frequency or the voltages?
[Eee Pad Transformer Android Development] guevor:
I do not know why they have problems, but if they really are doing the same and in the same state, and now works worse, have to attribute this to the tables, which are now different, and maybe the steps affecting the stability.

Perhaps to confirm this, make a version with the old tables.

However, being honest, I think that is less tolerant, and if a frequency seemed stable, but very tight, now fail before. But as I say, do not know, I have not proved beyond 1.2Ghz with the latest version, I want to test stability.
[Eee Pad Transformer Android Development] guevor:
msticninja, I updated my repository, you can see my changes. You see I have not touched clock.c from test11 (I guess saw those changes) but I touched the i2c, suspend and power.
[Eee Pad Transformer Android Development] habylab:
I was referring to the issue some are having of losing sound randomly, and having to reboot to fix it. You can google it, quite a lot of people I know have the issue.

Sent from my Galaxy S running Slim ICS 3.2 with Devil 2 xl using the XDA Premium app
[Eee Pad Transformer Android Development] guevor:
Ok, I have not had that problem and is also the subject of the loudness.

If happen to you, would you mind sending me the kernel log just after they occur, to see if it indicates something. Logcat may also help.

There are programs to get it (as os monitor), but with a simple terminal can get them.

dmesg > /sdcard/dmesg.log

Creates dmesg.log on the sdcard.

Thanks
[Eee Pad Transformer Android Development] dgcruzing:
Back to the hotel and the Asus Portable router and it hooked on no problems

Plus came up blue right away, so yes, I it was a teether issue.

I also plugged it into the dock for about the same time as last time and this time it didn't shut down..

Will run it over night and tomorrow as got a plane trip home.. So there will be plenty of up and down time with it

To see how stable it is..

That's half the fun of playing with this thing isn't it...

Be just another boring pad if we didn't have all of these ups and downs..

No problems with NFTS usbdrive either... Which is back to normal plug and play.

Thanks for the work so far..
[Eee Pad Transformer Android Development] Danzano:
Maybe have a look at blades or clemsyn's github for there work on hc they had a very similar setup but all frequency's for me where stable on those kernels and I never heard of anyone having problems so maybe it could help??
[Eee Pad Transformer Android Development] guevor:
From the comments I've read, I do not think that there were many more problems on test11 that in kernels from Clemsyn or Blades or in any case would have to test them in the same machines/frequency, because every machine is different.

The main problem I see is to establish whether a machine is really stable at a frequency/voltage level, it may work well in tests and many other things, but fail at some point, that can match other kernel test .

Anyway, I said, I will make another kernel to test the original table.

Indeed, as a curiosity, has anyone looked at the number on the kernel version to the right of livux@Tragon?

There are many internal tests, my tablet was more time booting than working.:p
[Eee Pad Transformer Android Development] gkillerx:
Version 4.4.0 :-P ?

After 15 houres :

44 min at 1504 MHz

12 min at 1000 MHz

54 min at 216 MHz

12:36 hours in deep sleep

And a couple of min in the other frequency and still 40% battery left. No reboot nor is it getting hot.
[Eee Pad Transformer Android Development] guevor:
One thing I would point out.

The SOD problem not necesarily need to be the same as the RR, I think in some cases be the same, but I've had some SOD while on adb (not suspend), and the kernel still worked, which had stopped working was the graphics. In fact at first I thought it was the backlight is not lit, and modified it to make turn on the light on these cases and the button was turning it on, but the screen was still black and the graphics controller was not restored.

Not sure If from the kernel will be able to do much (although I'll keep trying), but it is likely that nvidia libraries now using prevent us from fixing it.
[Eee Pad Transformer Android Development] CoopZor:
Yesterday i flashed kernel 13, this morning by waking up the screen was of and could not get it on, had to hold te power button for 7 sec. then it booted.
[Eee Pad Transformer Android Development] guevor:
That is what is commonly called SOD.

To find out what caused it, would have to leave in place a process to log the kernel messages.

If a terminal execute the following:

su

cat /proc/kmsg > /sdcard/kmsg.log

will run with root permissions, and will be process and save there all kernel messages in the file kmsg.log. The terminal need to be running, the command remains running.

Don't know if there is any program that stays resident keeping this log.
[Eee Pad Transformer Android Development] j3tt3:
I have been appending kernel # to keep track what kernel I am on. If you can include this # in the filename would be appreciated.

testing your kernels make me love my TF more...

it is not boring, at least.:p

guevor, you have done enough with kernels. why not on ROM?
[Eee Pad Transformer Android Development] weazil60:
With regards to no wifi on test13 I did try switching it off and on again - there was no response at all.

Thanks
