I would be interested in this as well, i'm running 21a on revolution HD and it runs great but I've had some crashes only in games.
[Eee Pad Transformer Android Development] keroppilee:
Clemsyn or Blades, is there anything we can give you that would help you figure out what's going on with plants vs zombies in your kernel?
[Eee Pad Transformer Android Development] breakthestatic:
Hey guys,

I looked through the thread for issues regarding the speaker sounds with the r4 kernel that was released yesterday. There isn't any consensus on what is causing it or any ways to fix it yet, right? Perhaps it might need to wait until we get the 3.1 source. Sucks, cause the kernel ran very smoothly w/ the overclock; no reboots, FCs, etc... I just can't stand the noise. It sounds like a mechanical hard drive ;)
[Eee Pad Transformer Android Development] rj3005:
I got NO speaker sound (I mean no noise but also no music on R3) R4 seems to work just fine for me.... AND.... 1.6Ghz seems to be stable on my transformer :)
[Eee Pad Transformer Android Development] Beretta93:
Thank you clemsyn for your work.

Could you please put a changelog for your different releases please? It would help us know what's new from one version or another.

Thanks in advance.
[Eee Pad Transformer Android Development] Mean Sixteen:
Can't remember if anyone else had this issue but my gallery fcs when opening up any pic.

It works for the previews, and also to open the specific folders but not a specific pic.

On elite at 1400.

Edit: after some diagnosis it is my theme not the kernel.
[Eee Pad Transformer Android Development] danielsjam:
On elite @1400 - no fc on any apps.
[Eee Pad Transformer Android Development] rjskalet:
Did you by any chance try fix permissions? I had this problem when I originally downloaded the kernel and that fixed my problem.
[Eee Pad Transformer Android Development] Mean Sixteen:
Actually I just did some experimenting and it seems to be my light blue theme. I reflashed rom, all good. Reflashed kernel, all good. Reflashed theme and broken.

However I can't remember how to fix permissions on the tf. Can you refresh me? I should know how and maybe I can get my theme to work.
[Eee Pad Transformer Android Development] GibMcFragger:
You can do it from CWM. :)

Sent from my Rooted and overclocked Transformer running Primordial v3.1
[Eee Pad Transformer Android Development] rjskalet:
you can do it in rom manager under utilities or you can do it in recovery. I believe in recovery its under advanced. Its easier just doing it in rom manager.
[Eee Pad Transformer Android Development] live_free:
How do you know if your "Tegra" is elite?
[Eee Pad Transformer Android Development] Mean Sixteen:
Thanks to both of you for your replies.

And I thought rom manager didn't work for the tf.
[Eee Pad Transformer Android Development] Mean Sixteen:
Try the elite kernel and see if it works.

If not then you aren't elite.

Mine can run the elite at 1400 but not at full throttle 1600.

I guess mine is kinda elite.
[Eee Pad Transformer Android Development] jhanford:
What should I flash to go back to stock?

I need to test out an FC issue I'm having
[Eee Pad Transformer Android Development] freeza:
I must be super elite because mine can run on 1600 performance 24/7
[Eee Pad Transformer Android Development] rjskalet:
Its been working on mine. I have done fix permissions like 6 or 7 times. I still haven't found a fix for this sound bug either. I have been trying everything.
[Eee Pad Transformer Android Development] jhanford:
Answering my own question: just flash whatever 3.1 rom again (in my case, Primordial 3.1)
[Eee Pad Transformer Android Development] Mean Sixteen:
Man I am jealous.
[Eee Pad Transformer Android Development] p0k3y:
Woohoo! Mine has been running elite at 1600 for a day now without problem. Score 5300+ on Antutu. Now I feel special!

PS: PvZ HD works fine with the elite kernel. Had issue with v3 kernel before.
[Eee Pad Transformer Android Development] baseballfanz:
You don't, run v4 and if you don't crash you have elite:D
[Eee Pad Transformer Android Development] Globespy:
Wow! Thanks for your help. Clemsyn! Talk about going the extra mile! Beer coming your way.

Thank you!
[Eee Pad Transformer Android Development] Danzano:
Any clues on which initial.d script? Which lines? Really need some more juice on the high end.
[Eee Pad Transformer Android Development] georgica81:
i don't think it's the OC of the GPU the reboot cause. i only get reboots at work, never at home. the only diferrent thing is the wifi - 802.1x eap vs. wpa2-psk. i also get wifi disconnects only at work.
[Eee Pad Transformer Android Development] clemsyn:
Can you please type this in terminal and post the output using kernel #13

cat /sys/kernel/debug/clock/clock_tree

Thanks.

BTW, you got PM
[Eee Pad Transformer Android Development] crzycrkr:
I apologize if this was asked or explained before, but is there any chance to get the smartass governors? They seem to work the best on the kernels on my phone, so I am just assuming they would work will here. I may also be wrong.
[Eee Pad Transformer Android Development] Danzano:
Would we be able to get bfs ?

ive found bfs to be the best on all my phones pcs and netbooks atm and its now in the android repository so woudnt be a mission to add :)
[Eee Pad Transformer Android Development] Danzano:
Playing dungeon defenders crashes all the time its designed for tegra 2 and mines o/c this shouldn't happen should it?

Also checked all background apps closed what I could still same tried underclock still same

Any ideas?

i believe smartass is optimized for single cores.
[Eee Pad Transformer Android Development] Danzano:
Which is why bfs that supports single dual quad and some hex is the man : )

Hi, i'm new here :)

I got a B70KAS14,

installed CWM

newest super user from http://androidsu.com/superuser

this kernel

nofrills from android market

And i'm able to run @ 1.680MHz.

Thank you for your kernel. i really dont have any idea about what voodoo module is, but i'm using the version with that :D
[Eee Pad Transformer Android Development] Danzano:
In that case search voodoo on the market and you will know : )

Pretty much it makes sound a lot better
[Eee Pad Transformer Android Development] JLneonhug:
Hi, thanks for the kernel, would just like to put a suggestion if i may. Could you possibly put the version number (currently 21) on the name of the kernel where it displays about tablet screen? Else is there a better way of knowing which version i am on?
[Eee Pad Transformer Android Development] georgica81:
i'm confused with this voodoo thing. that free app has only some checkmarks and dB levels. where is that improvement?
[Eee Pad Transformer Android Development] thebadfrog:
Unless your wearing headphones it does nothing.
[Eee Pad Transformer Android Development] Danzano:
True although it is a little louder when using headphones always a plus. Before I found it way to quiet.
[Eee Pad Transformer Android Development] zephiK:
Depends. On the Transformer this is the case, but on the Nexus S it has speaker boosts as well.
[Eee Pad Transformer Android Development] thebadfrog:
Since we are in the Transformer forum discussing Voodoo sound on the Transformer I guess having speaker boosts on the Nexus S will have little to no impact on the speakers on the Transformer
[Eee Pad Transformer Android Development] georgica81:
so this voodoo thing is almost useless for the transformer
[Eee Pad Transformer Android Development] thebadfrog:
No. When wearing headphones it dramatically improves the sound. Well worth it and maybe someday it will help the external as well.

Just realized this is way off topic. Sorry i will quit hijacking the thread now
[Eee Pad Transformer Android Development] gammagogeta:
I downloaded the kernel v21 and is trying to OC to 1.4 but it does not seem to work. I got setcpu and when I go into the setting the max I can go is 1ghz. I do not have the option to go to 1.6ghz. Any ideas why?
[Eee Pad Transformer Android Development] thebadfrog:
Did you flash the zip file in cwm?
[Eee Pad Transformer Android Development] gammagogeta:
I flash the zip file in recovery mode and it is showing up in about tablet. That is all I know. I do not know what cwm mean sorry.
[Eee Pad Transformer Android Development] thebadfrog:
I dont know why then
[Eee Pad Transformer Android Development] devilpera64:
i found it better reliable and stable...infact i can run to max speed clock without issues or reboot..also typin into browser is better than clemsyn version. I think that if blade's kernel is experimental, try to think when it will be alpha relase! just for now i take 4000 quadrant tests and 7000 antutù using Blade...with clem v21 i reached max 6690-6700. It's incredible how much difference are between those two kernels.! i think that our transformer can give us a lot of secret power ;) i think that is only an optimization side..
[Eee Pad Transformer Android Development] Globespy:
I don't care about quadrant scores.... they are not a solid representation of real world experience. Clemsyn kernels are very fluid, as and the UI is buttery smooth. Even with his kernels I don't ever overclock as I can't really notice a substantial difference in user experience between stock and 1.62ghz. And of course my battery goes down much faster.

If Blades can add voodoo sound support for his kernel I will give it a try, but without that it's a no-go for me as I can't live without voodoo. :)
[Eee Pad Transformer Android Development] georgica81:
i get around 7300 with clemsyn in antutu, and I can only go to 1624Mhz, not the max 1680.
[Eee Pad Transformer Android Development] wildestpixel:
Are you using superuser ? If so have you granted setcpu superuser access or blocked it ?

Transformer TF101 with Prime 1.9 @ 1.6
[Eee Pad Transformer Android Development] fserve:
CWM = Recovery, lol

With 21a, i can go to 1680, but it's stable at 1624mhz (tested with 3 hours of watching rock in rio on the tablet)

with that, 1624, i can reach 6900 antutu. Others kernel around xda aren't good as this one.
[Eee Pad Transformer Android Development] RAMBO29:
SETCPU no voltage control?

Why is SetCPU not able to control voltage with this Kernel?
[Eee Pad Transformer Android Development] clemsyn:
Releasing 22 soon...Here are the changes

1. Utilizing TCP congestion Veno in IPv4

2. Added handler for kernel command functionality

3. Added ioctl to set/get clk rate

4. reduce HDCP re-negotiation delay

5. fix hdcp hotplug issue

6. disable windows in dc disable

7. Avoid timer calibration on slave cpu

8. cross check connection state on receiving interrupt

Sorry to be out of topic here...just got a call and my second job is closing their business which has been open since 1968...Looks like we got hit hard by the current economy... :( ...but I promise to release this kernel tonight
[Eee Pad Transformer Android Development] clemsyn:
Will just have to release version A with voodoo module. Will release version B tomorrow.
[Eee Pad Transformer Android Development] fserve:
I really thank you for having TCP_Veno on my transformer :-)

Antutu score @1.624GHz 6857
[Eee Pad Transformer Android Development] gladi8r:
22a running very well here. Prime 1.9

Antutu went from 5400 to 5900 @1472. No other changes.

Smooth and clean feeling. Ill be testing more.

Thanks so much...
[Eee Pad Transformer Android Development] chatch15117:
I've found myself checking back in this thread less and less for updates as I'm becoming close to 100% satisfied with the performance!! Lickety-split fast, as my dad would say.

If only the browser wouldn't crash... It happens a lot when I change orientation with lots of tabs open.
[Eee Pad Transformer Android Development] zaindon:
Ok :(

But I totally understand the hardship that you are going through right now
[Eee Pad Transformer Android Development] Kaleptik:
Thank you so much Clemsyn.

I now have an updated kernel from version 10 that works without changing voltages.

Version 22A is the best.
[Eee Pad Transformer Android Development] fserve:
@Clemsyn, veno isn't default for now! (v22)

$ cat /proc/sys/net/ipv4/tcp_available_congestion_control

> cubic reno veno

$ cat /proc/sys/net/ipv4/tcp_congestion_control

> cubic

Cubic is default.

To set TCP veno, is needed to run (for now, v22)

su

echo veno > /proc/sys/net/ipv4/tcp_congestion_control

make a script for that, lol and put in init.d, lol

to make sure if veno is running, type:

$ cat /proc/sys/net/ipv4/tcp_congestion_control

> veno.

What TCP veno is? google it. But it's really great.

CPU1 is that actual cpu 1 or code for gpu or core 2 I ask because sometimes things are named what there not for some reason or another

I had no idle tasks at the time that I know of I was actually playing my favorite game

Any help would be great and if anyone needs full ram dump file just ask I've got a few of em
[Eee Pad Transformer Android Development] vrundmc:
are you guys flashing 22A with prime or revolver - even though we need the non-kernel version?
[Eee Pad Transformer Android Development] a.mcdear:
22a works just as good as 22b for Prime 1.9+, the voodoo drivers aren't included in the rom anymore to make compatibility easier with custom kernels
[Eee Pad Transformer Android Development] nicandris:
v22 works with Android 3.2.1 ??
[Eee Pad Transformer Android Development] gbroon:
Using 22a with revolver, just disabled the voodoo module.

edit /etc/init.d/08 modules and comment out/remove the line with voodoo in it.
[Eee Pad Transformer Android Development] a.mcdear:
So, I had been using 21b since it came out now without a problem, until this morning. All of the sudden, as of this morning, I am getting the "tablet will not charge when plugged in" bug that people have been reporting. In addition to that, the screen auto-turnoff stopped working as well, completely ignoring the turn-off delay and just letting the screen stay on indefinitely.

I was able to fix the problem by wiping cache and re-flashing the kernel.

The reason I post this is because I think something corrupted the integrity of the kernel, and I believe it was the result of aggressive undervolting.

I have checked, and am positive there have been no reboots, as there are no ramdump files on my device. My current thought is that the undervolting has caused enough problems to slowly corrupt data on my device, but that the problems aren't "pronounced" enough to cause the reboots other people are seeing. I have had this same problem happen to me once before with a previous kernel, and I was also using aggressive undervolting then as well.

On another note, I installed 22a today and have noticed already a few times that my tablet has disconnected from the wireless network at my office again.. I still have my tablet undervolted however. I will re-flash the kernel and return the voltages to stock and see if I notice any more issues.
[Eee Pad Transformer Android Development] Globespy:
I am glad to read this post. I was having constant problem with rebooting always during the night when tablet was in sleep mode. I've flashed a bunch of roms and kernels since owning my tablet, and could not figure out why the rebooting was happening? The ramdump.log would have a bunch of garbled info suggesting kernel panic. I tried going to prime 1.9.1 with the stock kernel, same problems. Clemson thought that my issues were because my GPU could not handle increased timings, but even on earlier versions of kernels such as v13b which did not have these GPU settings, I still had issues. Interestingly, my previous experience with v13b was perfect, but after upgrading to subsequent kernels my problems surfaced. Roach suggested that my tablet might have faulty ram, and would likely need to be rma'd to asus.

So I completely wiped the entire machine and went back to stock rom. As a nice added benefit i've had it upgraded to 3.2.1 which is running every bit as smooth as even the fastest rom/kernel combo, and it's stock! But the main thing is that after 2 full days i've had zero rebooting, or ramdump.log!

Makes me believe that there's something in these kernels that is causing data corruption and hence the issues.

Of course I will plan to root again as I need certain apps, but I will be sit back and watch kernel development for a while before changing back to custom kernel.

YMMV :)
[Eee Pad Transformer Android Development] Globespy:
I'd be cautious. I recall there were issues running kernels from 3.1 on 3.2.

Sure, you could argue that this latest rom update is minor, but I'd wait for the developers to test it first.

Or be the Guinea Pig! Let us know how it goes.
[Eee Pad Transformer Android Development] nicandris:
well i tried it so you wont have to :P don't try it at home guys/girls :P not working

nvflashing my transformer from the begining :P

btw, a bit irelevant, but did any of you tried restoring a backup from cwm? mine never works!! it only gets bootloops
[Eee Pad Transformer Android Development] bradputt:
From what I could remember cwm cannot backup the boot partition.

I may be wrong tho.
[Eee Pad Transformer Android Development] Globespy:
BTW - I read on the revolver thread that a user updated to revolver 3.5 (HC 3.2.1), and then successfully flashed clemsyn v22.

It must be a strange kernel/rom thing.
[Eee Pad Transformer Android Development] gbroon:
I've been running 22 on revolver 3.5 with no problems, its been running all day, no reboots etc.

Revolver 3.5 +v22 running fine-NTFS Issue solved!!!

Just flashed v22 on revolver 3.5 , running fine. Voltage options are back in SetCPU.Voodoo works as well.

However the NTFS USB drive is not listed under removable drives.After plugging in, it shows a very short preparing external USB and then it disappears. I do not know why.Any one can help?

Big NTFS edit:How to get NTFS USB working If Any one else has the problem of USB NTFS drives not being recognized/then do like this:

1)Go to http://www.megaupload.com/?d=YNWIWCJI or from http://xdaforums.com/showpost.php?p=14894212&postcount=1Download NTFS.zip at end of this post.

2)Unzip and copy NTFS.KO to an SD card.

3)Use Rootexplorer and navigate to Removable (choose if you have the SD card/Micro SD) then click the 'NTFS.KO' and in the enu choose copy then go to System--> Lib-->modules. On the top of rootexplorer, there would be 'Mount R/W'. Click on it and it will change to 'mount R/O'. below there would be paste and then click on it. Now NTFS.Ko is copied to modules folder.

4)Reboot and when the USB drive is plugged in there would a an icon with picture of USB near time area and then it is in the removable drives.

Hope it helps. I do not know why it is not there by default even though everyone says NTFS is supported natively!
[Eee Pad Transformer Android Development] devilpera64:
This file is just included inside Revolver and unfortunately i tried it witout success..i'm using Blades kernel and nothing :-( if i use Clemsyn 22a it read all NTFS devices..however Clem's kernels on those last relases don't propely scale frequency from CPU and i prefer Blades's kernel for a better Battery Drain (if i use Clems kernel CPU stay for long time on max frequency set up).
[Eee Pad Transformer Android Development] wildestpixel:
I'm also confused around the Prime and Voodoo thing.

Yes it works with the free voodoo control app but should I be running the B version and what is the deeper reason ?

I see lots of b versions for prime but don't see the pitfalls of running the a version.
[Eee Pad Transformer Android Development] zaindon:
clemsyn bro are you working on the new kernel 2.6.36.6 :D
[Eee Pad Transformer Android Development] Sageth:
I upgraded from Prime 1.9.1 with the 21 Clemsyn kernel to Prime 2.0.1 with the 22 kernel. I noticed that with the stock kernel from Prime I would get a higher score in Quadrant (150-200 more points) as with kernel 22 which I had overclocked to 1425.

I also noticed that I couldn't get my CPU to downclock anymore after I had set it to Performance for the Quadrant test. No matter which setting, no matter if I changed the maximum OC back to 1000MHz it always stayed at 1425MHz. A reboot didn't fix it either.

I might actually go back to Prime 1.9 with kernel 21 with a 1425MHz overclock, it felt faster. Except for the drawing of widgets on a fresh boot, that always took some time to happen, except with Prime 2.0.1 stock.
[Eee Pad Transformer Android Development] dgcruzing:
Just had this problem too.. had to copy the NTFS.KO file across as above and it fixed it..

not sure if this is a kernal or rom problem..

but it need sot be pointed out to both developers.. its a bug for sure.. as I had no problems with same USB drive this afternoon before flashing..
[Eee Pad Transformer Android Development] RAMBO29:
Never worked for me without manual copy. You can try it as well.
[Eee Pad Transformer Android Development] Globespy:
The b versions do not have the voodoo sound module built in. So if you don't have the paid version of the voodoo control app, then you have to use version a because the free version of the voodoo control app does not have the driver built in.
