Anyone has got issues with ksoftirqd eating about 10% of CPU when idle? I'm pretty sure it has to do with kernel but can't figure out for sure. Thanks in advance!
[Eee Pad Transformer Android Development] Diablo67:
I havent had that problem,i believe its all where you set your cpu,i'm @ 15400,and it runs smooth as silk.16000 gave me random boots and other force closes.
[Eee Pad Transformer Android Development] Diablo67:
Set your tab to airplane mode,that seems to work for me,since thats the only way to charge this thing without a dock.
[Eee Pad Transformer Android Development] sontin:
Wifi is not a problem. My Transformer is going to deep sleep with wifi. You should disable setcpu and recheck the states. Maybe the profile is reason for this problem.
[Eee Pad Transformer Android Development] Basileus_AU:
Well, it turned out that any governor except INTERACTIVE is cause it. If set conservative/ondemand this process will eat 10% of CPU regardless of the load. Will stick to interactive for now.
[Eee Pad Transformer Android Development] clemsyn:
Github updated :)
[Eee Pad Transformer Android Development] sontin:
Clemsyn,

i have two question:

It's possible to add more CPU steps like 1100Mhz and 1300Mhz?

And can you readd the higher gpu and vde rate?
[Eee Pad Transformer Android Development] clemsyn:
Yes it is possible to add more cpu steps ;)
[Eee Pad Transformer Android Development] sontin:
Great, i hope you can add it. :)
[Eee Pad Transformer Android Development] devilpera64:
What do you think about the possibiylity to push up Tegra 2 on 1.8/1.9/2Ghz? on Motorola xoom are working for adjust voltage table for better stability and for squeeze more power...Maybe the gap between Tegra 3 will be reduced if Tegra 2 would have double power from stock). What's the problem? :)
[Eee Pad Transformer Android Development] chatch15117:
At 1.7ghz we are nearing the voltage limit as specified by nvidia.
[Eee Pad Transformer Android Development] clemsyn:
The most I was able to push my tegra2 was 1.646 ghz and it's the max voltage. I think going beyond 1.7 would be pretty difficult. I would see how the xoom takes it but we have to consider that Xoom is not ventana board like our transformers. I believe we can increase the limits and go for 1.9 but Im not willing to burn out my tegra chip on my transformer at the moment (unless I get a donation for another Transformer ;) then I would do it )
[Eee Pad Transformer Android Development] devilpera64:
I'm having a conversation with skype and transformer slow down on 1.6Ghz interactive...menù swapping is a bit choppy, so if we can reach more power would be fine..for temps there are no probs coz with interactive mode there are no risk i think :) why do you think that on xoom tegra 2 isn't the same of TF? how many typs of tegra 2 there are? mmm i doubt...however i red on xoom forum that is a source code problem..in next relases would be better for reach new performance :)
[Eee Pad Transformer Android Development] LucJoe:
The tegra 2 chip is the same, but the SoC (System on a Chip) is different. We have the Ventana SoC. I'm not sure what the Xoom uses...
[Eee Pad Transformer Android Development] devilpera64:
Ok i red something..there are 2 SoC: Ventana and Harmony. Devices like the ViewSonic G-Tablet, Notion Ink Adam, Advent Vega, and ViewPad 7 are powered by a version of the Tegra 2 chipset known as the “Harmony” platform. These tablets unfortunately never see the proper drivers to get Android 3.0 Honeycomb up and running smoothly. Without the correct drivers for these devices, it would be a very poor experience – hardware acceleration of the UI will make a big difference. So this platform was discontinued and Nvidia is only supporting the Ventana platform that support Honeycomb newborn. So also Motorola Xoom use Ventana SoC, and on this way we have to look behind the xoom works..(ex. WPA_supplicant wifi relase was created for xoom and fortunately the O.S is the same for TF for copy it inside our devices). By the way, if Xoom devs says that it's still possible to push up the power i would hope in this!

I know that if the CPU stay on high voltage for few time, after it can be low also staying on the same frequency (it's a phisical electricity state). :) Impossible is nothing!! ;)
[Eee Pad Transformer Android Development] branshaw09:
Good morning, and happy Friday. Last night i started playing on google maps, more specifically downloading area maps for ofline use. After doing this my TF went into a boot loop. Thoughts? This happened on 2 separate occasions. I am have my TF set to 1400 max with profiles in setcpu. I have had ZERO prlblems before this.
[Eee Pad Transformer Android Development] supercurio:
I updated Voodoo Control on market!

Now the Free version support Honeycomb with this kernel :)
[Eee Pad Transformer Android Development] devilpera64:
What do you think about Android 3.2? On Xoom will be avaiable the update in those days..
[Eee Pad Transformer Android Development] MarlowXim:
@Clemsyn for your upcomming kernel versions can you increase the voltage of the 1600mhz stepping to 1450mV and users can simply undervolt to adjust for maximum stability.

I viewed you're git but you simply just uploaded your souce after modifications so it's kind of hard to make sense of how you adjusted voltages. I believe theirs +50mV boost to the default clocks after taking a look at netanarchys sources.

Anyway I am enjoying you're kernel hoping for a better voltage range in your next release.

Also saw that you patched in arm errata fixes are they from the kernel configuration selection? They usually cause instability atleast in my own experience.
[Eee Pad Transformer Android Development] xTRICKYxx:
Finally got my microsd card and I'm running 1.6Ghz perfectly. It is not much of an improvement from 1.5Ghz using CPU Benchmark. I may try the 1.7 Ghz kernel, but I'm not sure it will matter all that much. I would be interested in attempting to undervolt, but I have never done that. But wow, my little tablet is running a dual-core 1.6 ghz processor!
[Eee Pad Transformer Android Development] clemsyn:
Thanks supercurio :)
[Eee Pad Transformer Android Development] clemsyn:
I have the 1646 at 1450 at the moment, it shouldn't be an issue to make it the same at 1600 so I will look into it and will integrate it in version 18.
[Eee Pad Transformer Android Development] MarlowXim:
I might take a crack at it soon once I get my build environment going. I also notice any reason why noop is the io scheduler of choice. Cfq and bfq are better for multitasking despite the overhead.

Also I think you can compile with o3 flags you just need to add compile as o2 for kbuild subdirectory for instance wolfonson sound driver to avoid crackling noise when played and or when you get compile errors. It usually a notable increase in smoothness
[Eee Pad Transformer Android Development] wallah:
thank you for this update, just one question, can i flash this over your rom or all features included allredy ??

Thank you
[Eee Pad Transformer Android Development] snakeybidder:
Unstable

Hi guys and thanks for this active work your doing.

Im using 1.5 prime and flashed this kernal with a cache wipe etc.

For some reason even going to 1.4 reboots and freezes my tf. I know it can easily do 1.4 as ive run it like that for a while before.

Is there anything i need to do with the voltages in setcpu or?
[Eee Pad Transformer Android Development] d.brown:

Sent from Cybertron!
[Eee Pad Transformer Android Development] brando56894:
Awesome! I can finally run at 1.6 GHz with this kernel thanks!

Edit: it's not perfect, but at least it doesn't crash instantly like it did before. I agree that higher voltages for 1.6 GHz would be a nice option since I was looking for a way to adjust the voltages too.
[Eee Pad Transformer Android Development] Ke1evraTi:
This there a way we could get the dock battery and the tablet battery to show up separately? Currently all the widgets I have tried say that the battery is unsupported.
[Eee Pad Transformer Android Development] mattykellyuk:
Search in the market for something like eeepad transformer dual battery widget should come up there.
[Eee Pad Transformer Android Development] mskip:

[Eee Pad Transformer Android Development] AngryDinosaur:
so 312 to 1400 ok?
[Eee Pad Transformer Android Development] chatch15117:
Version 17 sounds good. Does it auto OC to 1.5GHz?
[Eee Pad Transformer Android Development] Ke1evraTi:
I installed this app as well as several apps that I found on the market and none of them work. I get a message that says I need to use the stock kernel because dock battery support is not integrated into the kernel.
[Eee Pad Transformer Android Development] miatawnt2b:
This is the most stable kernel at 1.6 yet. Ran for almost a whole day before it rebooted. Had to back it down to 1.5. Is there something I can do with voltages to make it more stable?

Also, I am using setCPU. I am a little confused by thevoltage settings. Why do thevoltage numbers decrease as speed increases?

Thanks!

What do you guys score on quadrant ? I think i score quite low.. Only 2300+/- on 1.5 Ghz :S
[Eee Pad Transformer Android Development] thaddyusmaximus:
Update the dual battery widget. It works fine using prime 1.5. I was only able to get the older version to work with the Clemsyn kernel.
[Eee Pad Transformer Android Development] brando56894:
On Monday I got 3562 @ 1.6 GHz :D
[Eee Pad Transformer Android Development] Kevincod:
I get constant lockups using kernel v17 without even being overclocked, prime 1.5 and version 16 is fine.
[Eee Pad Transformer Android Development] thaddyusmaximus:
Is there anything wrong when running 1.4ghz. It was running fine alnight long until I rebooted it this morning. Now I get the constant reboot cycle. I tried reinstalling prime 1.5 but didn't work. Tried wiping in CWM and didn't work. I was also running the latest SetCPU to set it to 1.4. Only the initial wiping (VolDown + Power, then Volup) worked. Lost all my apps :(. I guess it was time. At least it boots up alot faster now.
[Eee Pad Transformer Android Development] Basileus_AU:
I've got the same problem, will revert back to 16 I guess before new version rolls out
[Eee Pad Transformer Android Development] chatch15117:
still on 14B... works wonderfully. No effort... I hate setting the OC after waking from sleep. With 14B it is always at 1400 unless I change it.
[Eee Pad Transformer Android Development] superevilllama:
17 def has issues, 16 is great

+1 on the lockups on 17 gave me a scare because I did a bunch of things at one time.. updated kernel, got a new keyboard dock, updated setcpu.

I kept freezing all over the place and rebooting, OC or not. Thought I restored back to stock kernel but I didn't. Saw this thread and check and I was still running 17. Back to 16 and all is well, both when not overclocked and OC to 1.5

I appreciate your work Clemsyn. I know you will get it working!
[Eee Pad Transformer Android Development] Xhyperion:
I'm thinking about getting a transformer but I was curious about how the ps3 controller works with the tablet. Is it fully functional? Does it work with emulators such as pse or psx4droid?

On my epic in purchased a game gripper to go over my keyboard.

This functionality would definitely help move me in this purchase.
[Eee Pad Transformer Android Development] MarlowXim:
I think it was due to the tweaked voltages. Clemsyn decreased the voltages for some steppings for example 1503 MHZ was 1325 mV to 1300 mV. I find things alittle more stable with the extra +25mV but it varies from chip to chip. Hence my recommendation of upping voltages 1500+ steppings so everyone can find their sweet spot.

@Clemsyn I've been reading technical documents on Tegra2 like optimal compiler flags in you're config you have vfp, since tegra2 does not support neon extensions. They recommend compiling with this flags

-O3 -march=armv7-a -mfp=vfpv3-d16 -mfpu=vfp –mfloat-abi=softfp

However I know I am missing something I have to create a kernelblob hwo do i go about doing that. I'm guessing its to package an initramfs? I have the zimage compiled already.
[Eee Pad Transformer Android Development] hyperxguy:
I have no issue with the latest v17. I actually don't really need to overclock but am running @1.2GHz and even reduced the voltage to 1100mV (from 1150mV).
[Eee Pad Transformer Android Development] Basileus_AU:
Guys, would be very glad if someone could share their STABLE voltage settings in the following format:

I'm using Clemsyn's ROM+kernel combo 2B

The browser sometimes crashes, but it seems to do that regardless of what i set the cpu speeds and voltages to. Using firefox, the pages that give me problems are fine.
[Eee Pad Transformer Android Development] xreflection:
Is it possible to use this kernal with stock 3.1 w/ root?

EDIT: well lets give it a shot, some people previously said it worked.
[Eee Pad Transformer Android Development] MarlowXim:
Usually the browser crapping out is due to instability I'd run flash through the browser and see if it locks up hard resets etc. I can also run it the voltages you indicated but eventually something craps out causing a hard reboot.
[Eee Pad Transformer Android Development] daveloft:
It worked for me
[Eee Pad Transformer Android Development] zephiK:
On the bottom your TF101, there's a sticker that says S/N. I dont know if you took it off or not. But the S/N will start with B40/B50/B60/whatever.
[Eee Pad Transformer Android Development] Radeon1337:
Ahh.. Thanks ! I have a B60 model if anybody wonders :p
[Eee Pad Transformer Android Development] krash183:
Can we do the new ota update w/out it messing up root and kernel?
[Eee Pad Transformer Android Development] xreflection:
Nope. I'm running stock 3.1 with root and this kernal, and when I try to do the update, it is unsucessful (does the android with yellow triangl and a !).
[Eee Pad Transformer Android Development] krash183:
That sucks.... my tf101 just downloaded the update and I cleared the cache hoping that annoying reminder would go away but to no avail. Just my ocd kicking in
[Eee Pad Transformer Android Development] xreflection:
If you want it to go away, just let it try to install the update. Your tablet will restart and then eventually get to the android with the yellow triangle. Just restart your tablet again and the notice should be gone. It disappeared for me.
[Eee Pad Transformer Android Development] krash183:
Even better since I cleared the cache it simply said it couldn't and will stay at the current configuration....perfect hahaha
[Eee Pad Transformer Android Development] smarron:
Just upgraded from 1.6 to 1.7 and set the voltages the same as above, thanks for that. I also have a B50KA but on the Prime 1.5 ROM. It's running very well for now. 1.4Ghz is the max. I will run. A stress test in SetCPU was running fine for 15 minutes in a row.

So more speed with less voltage! I'm very happy!
[Eee Pad Transformer Android Development] chatch15117:
Any free apps to adjust voltages?
[Eee Pad Transformer Android Development] chatch15117:
I'm on version 15 now, trying 1.6GHz out because adobe reader renders a lot quicker with higher overclocks. I used CPU Master(free) to set the max to 1600... no voltage settings were changed.

Is the battery going to drain like crazy? I assume version 16 decreases the voltage a bit... just says "changed". If it drains in a couple hours then I'll go back to 1400MHz with 14B.
[Eee Pad Transformer Android Development] MasterfullDON:
Awsome, Works very well at 1.4.
[Eee Pad Transformer Android Development] hyperxguy:
I'm waiting for Prime1.6 to be released.

Is there any problem applying this Kernel over 8.4.4.11 ? Thanks.
[Eee Pad Transformer Android Development] AnTrans:
xda forum members can get setcpu or pimpmycpu for free. Both can undervolt and overclock. Personally I like setcpu better.

They have a modified version already built in. I installed a script from the zip just fine.
[Eee Pad Transformer Android Development] DroidRevenge:
BOOTLOOP

installed and tf bootloops just after home appears

Some explanation?
[Eee Pad Transformer Android Development] chatch15117:
Would the kernel have anything to do with file copy limitations? I'm having trouble copying over a 1.6GB file via USB to the internal 16GB memory. \Movies\

There is enough space left on the TF. Around 10GB left.

http://www.youtube.com/watch?v=bATmmM2BawM

EDIT: http://www.youtube.com/watch?v=fDiP3ID3fjg

NVM, obviously not the kernel. Feel free to give me any suggestions about how to make this work on the host OS! I don't want to boot a VM every time I copy a large file over to the TF. Copying from hard drive to hard drive or other network shares works. It's just a problem with the TF :confused:. Reinstalling drivers...

Furthermore: I just copied over a 2GB movie file from my collection on the host pc. So what's up with this Top Gear episode???? Windows never fails to amuse me...

Have you tried clearing cache and fixing permissions in CWM?

Mark.
[Eee Pad Transformer Android Development] GwynBleidd:
Hey Clemsyn,

Just asked these in Netformer thread but I'm not sure whether the OP checks it out often, so let me ask the same about your kernel... Do you think we can optimize it further for performance and battery?

- ext4 no journal filesystem options

- noatime, nodiratime (is it already there? not sure)

- jhash3 instead of jhash2

- HZ value (what's the current one I wonder? 500Hz was the best for SGS, made things look much smoother)

- what codesourcery are you using? 2010.09 seems the best

- new tiny RCU

- remove debug logging

Just throwing in some ideas.

EDIT: noauto_da_alloc is a good idea too for ext4. Also, no journaling at all might be a bit of overkill but data=writeback instead of default data=ordered should speed it up by quite some value.
[Eee Pad Transformer Android Development] dazz87:
For some reason my TF (B4) cant undervolt at all. I keep on getting crashes all the time. Its weird, cause with the custom voltages on all the cpu speed from 1500-216MHz it pass the cpu stress test under pimp my cpu, but when I surf the net or listen to music, my TF will crash....:( The rom I am running is Prime 1.5...
[Eee Pad Transformer Android Development] poussinou69:
Hi Clemsyn,

Do you think update your V17 (maybe V18 ;-) with new features like nvidia's updates you have implemented in your 3final ?
[Eee Pad Transformer Android Development] clemsyn:
yes, uploading at the moment with Blades latest timings ;)

Here are the changes

1. Max overclock set at 1.640 as per blades

2. avp/vde/bsea/bsev/sclk/hclk overclocked to 300

3. Read_ahead set at 1024 in kernel so if you are in stock rom, this will set at 1024.

4. slight changes in interactive governor

5. GPU 3d/2d overclocked at 425

WARNING: Not all transformer can take this timings so please backup and make sure you are familiar with nvflash :)

Update: It's out
[Eee Pad Transformer Android Development] sontin:

[Eee Pad Transformer Android Development] chasy:
Yeah .. trail and error wouldn't be such a good idea .. once you fried your gpu, your TF is dead.
[Eee Pad Transformer Android Development] krash183:
Does v17 have any gpu OC? Or is it v18 that has GPU OC?

Is the same as the one found in your rom v3 final? If so.... only elite tegras can run your rom?
[Eee Pad Transformer Android Development] nordicfastware:
"and make sure you are familiar with nvflash"

It's like go skydive, just make sure you have a parachute before you climb in the plane...
[Eee Pad Transformer Android Development] nordicfastware:
I don't think you can fry it so easily, it is more like it will be very unstable and crash all the time, but I am no expert...:confused:
[Eee Pad Transformer Android Development] clemsyn:
Versio 17 has gpu overclock but 2d has only 400 and only vde overclock. It doesn't have the bsea, sclk overclock.
[Eee Pad Transformer Android Development] phlunkie:
Edit: installed the latest setcpu (2.24)version. Works.

Disregard:I am using setcpu and the top voltage says it is 216MHz with 1450mV and on the bottom it is 1640MHz 825 mV. Is this flipped? Is setcpu not recommended?:confused:

Went ahead an flash v18 stable so far runs smooth but running antutu and quadrant got me lower scores.... weird

Any way to check GPU stability?

went and tried undervolting for the first time..... tried -25mv at each step....then -50mv..... thats where im at now; how much did you guys undervolt?
