How do we know this actually works? I suspect it doesn't; even if memory bandwidth or some other factor were limiting across-the-board performance increases, I don't see any, anywhere. All the results submitted to GLmark are within the margin of error - mine, running this kernel included. In fact, it's quite remarkable how little any of the tests, across any of the categories vary even across markedly different ROMs and (presumably, therefore) kernels. Miles behind the Xoom, especially in the offscreen tests which are device screen-res independent when apparently the Xoom's architecturally-identical GPU runs at 333MHz... Honeycomb, maybe?

Anyway, Tegra 2 is shockingly slow compared to Mali 400, Adreno 220, and even the SGX 540 it should be about equal to in GLMark. Still, one benchmark is not the be-all and end-all of things. This kernel is fantastic :)
[Atrix 4G Android Development] MrCoolBear:
Any full Res graphics benchmark is gonna be slower on our phone, pumping out full qhd, than any other phone putting only 400x800, regardless of the processor. To compare accurately, compare our phone to phones with different processors but qhd screens.

Hi, im having heating issues with the enhanced and the standard kernel on Aura rom. after 4-5 minutes of regular use the phone starting to warm up. is there any thing I can do?

thanks

Those UV settings there... mine are just about there, except I have 912Mhz at 900mV. 100% stable across latest versions of both CM7 and The Darkside.
[Atrix 4G Android Development] s0dhi:
Those marked in red seem to have a 125mV step - are they actually working like that or is the setting being ignored? I thought steps of 100mV (max) were only possible.
[Atrix 4G Android Development] dimako83:
I will try that. Thank you very much. I was afraid to do so because I dont know how it will impact my phone as I have never overclocked and underclocked my phone.

I am sorry for the question but what is different between faux kernel and AT&T 2.3.4 stock kernel that makes the phone go so hot? I was using AT&T stock (now I have the International version) for a day all day long and it was not getting so hot and did not started to warm up from just opening emails menus and so on. I dont mean to be rude just trying to understand.
[Atrix 4G Android Development] ghost_og:
Just remember not to check the "Set at boot" box when testing different uv settings. You don't want to get stuck in a bootloop if your phone can't handle a certain setting. As long as you take your time and test each frequency prior to setting it, you shouldn't run into any major problems. Every phone is different so don't pay too much attention to other people's settings, see what works for you.

Regarding heat issues, see faux's post from a few pages back:

It's funny that you see heat issues when using faux's kernels. It's the exact opposite for me. My phone used to burn up when I was on the AT&T kernel.
[Atrix 4G Android Development] sk8trix:
I get about the same amount of heat.I'm on the newest 1.3 kernel and I'm doing okay.I do notice on webtop it geta pretty hot so I kinda try not to use webtop much untill some update or patch for it is released.
[Atrix 4G Android Development] Mphill46:
I am running the ba2tf cm7.. I am wondering if this rom already uses the modified 1.0 kernel if not where can I find the kernel that comes with the ba2tf rom just in case I run into problems when I try to flash the modified 1.0ghz kernel? Any information would be greatly appreciated. Also how do I know if the 1.0ghz enhanced kernel is the latest?? I see it posted on the first post on this topic l, but that was also some time ago.
[Atrix 4G Android Development] yeahmann:
My extreme undervolting:

Enhanced kernel:

Couldn't get mine that low, but what it sits at isn't too far off to notice :o
[Atrix 4G Android Development] clemsyn:
I believe it has something to do with one of the tables in cpufreq.c. Looking at faux's github, there seems to be an extra table. I'll shoot him a PM and see it helps with this issue :)

I been overlooking this for an hour bcause faux123 changed his profile pic lol anyway no abnormal issues to report ! with 1.4.5 exept a lil heat but its ok

Question here, rom AT&T on another carrier, using PPTP VPN, connects ok, but don't get internet from the vpn ... tried with the computer, it works, but phone not working, could be kernel related or the known motorola bug for vpn from android 2.2.2 (I'm on 2.3.4)

Regards!.
[Atrix 4G Android Development] morrislee:
It is OC, it WILL get hotter period. Undervolting can reduce SOME heat, wont be as good as stock frequency of course

[Atrix 4G Android Development] osx67:
Hi all

I'm on CM7 Ba2tF; and of course with missing ram (only 815 ram available). I tried Atrix-CM7-Kernel-stop-ext4-1.00GHz. Nothing happened new, got exactly the same core than before!! Am I missing something !??
[Atrix 4G Android Development] Antzor:
afaik the system reserves a set amount of ram which is why you only see 815mb available. So you're seeing the proper amount. Someone correct me if I'm wrong though!
[Atrix 4G Android Development] Abu-7abash:
Spot on.
[Atrix 4G Android Development] osx67:
Ok, that i can understand, but why I get the same score when benchmarking? It says my score is quiet poor!! :mad:
[Atrix 4G Android Development] nelsonw:
Just for the record: this kernel works on 2.3.5 build 4.5.133...
[Atrix 4G Android Development] Swiftks:
Are you setting min and Max to highest frequency before benchmarking?
[Atrix 4G Android Development] osx67:
Yes I did, and no visible changes...:mad:

I've been running CYANOGENMOD 7.1.0-Ba2tf with the CYANOGENMOD 7 Kernel 2.6.32.39 1.45 Ghz faux kernel...

And I cannot get the wifi to connect, I find the networks... try to connect and it's not working. Tried with several wifi networks that used to work without luck. Do you have any idea?

Hangs a while in "obtaining ip address" and then shows "unsuccessful"

Thanks in advance... your work is awesome.

My device is overclocked and undervolted for the slower frecuencies.

Thanks again.
[Atrix 4G Android Development] osx67:
For wifi connection, just go back to recovery and wipe cash. Should be ok.
[Atrix 4G Android Development] jpbelli:
Exactly the same behavior...

Wiped cache partition and wiped davink (or something like that :p) cache

Version 022 for CM7 is here:

http://www.multiupload.com/Z2O6WTAUT0

for complete change log see OP! (lots and lots of enhancements and bug fixes).

CPU freq is FIXED! You should be able to set the clock to what you want and it WILL remember it.

Gingerbread version will come later!
[Atrix 4G Android Development] sublimejosh2000:
I think I just had an orgasm.... I just can't wait to flash this, I don't know how it could be better, your 2.1 has been rocking my face off... thanks for your hard work!!!
[Atrix 4G Android Development] MyronJ906:
Just as I was about to go to bed. Downloaded. About to transfer to my phone, flash, and play around.

Here's my preemptive "excellent work!"

You're always pushing it Faux123, it's much appreciated. This definitely made my night.
[Atrix 4G Android Development] Swiftks:
Not trying to sound ungrateful, the new kernel does work well, just tested it. Setcpu keeps at the frequencies you set.

BUT (I know, always a butt :P )... can you make a updated 1000 MHz enhanced version too. I know i can simply set the max to 1000 MHz, but I like the extra steps at lower frequencies, and I can therefore undervolt more as well.

Thanks for the hard work though. Always enjoy your kernels.
[Atrix 4G Android Development] mikarbach:
Same for me!
[Atrix 4G Android Development] fleurdelisxliv:
thank you just flashed the new kernel :)
[Atrix 4G Android Development] Kenchinito:
Are we still experiencing widget loading issues with this kernel? or was it fixed long ago? I flashed CM7 a while ago and have been happy so far, but now that it has 1.45 Ghz, it is so tempting =)

thank you for pushing through even sick, i'm excited to flash the enhanced 1.0 [since I just flashed the older version about a week ago]

my phone doesn't get hot as much anymore on the older kernel so i bet the new one is even better
[Atrix 4G Android Development] nelsonw:
Link is down...

Fixed some derpage on my part.. sick and tired == FAIL.

If you downloaded the 022 for Gingerbread earlier, update your kernel to the new version 022_r2

its an issue with te proper source not being released i believe. mine took FOREVER but it started working eventually
[Atrix 4G Android Development] zcrugby:
trying to run a quadrant benchmark on gb and aftre it runs and the message comes up asking if i want to see the results i click yes and i get a error message that says service call failed. it worked before i put this kernel on. any suggestions? still waiting for my wifi :(
[Atrix 4G Android Development] Anthonok:
I can't wait for a 1.2 so we can atleast go head to head with the same processor speed as the SGS2. Got a feeling its gonna still blow us away but it will atleast be a fair fight that way.
[Atrix 4G Android Development] djkinetic:
20+ minutes later still no wifi popup, QQ =(
[Atrix 4G Android Development] Sinful Animosity:
It'll come. Just make sure you have it turned on.
[Atrix 4G Android Development] djkinetic:
thank god for unliimited 3g-4g LOL... guess ill b limited to wifi at home and at the office only for now heh
[Atrix 4G Android Development] joe ferreira:
the service call failed because you didn't have a internet connection.
[Atrix 4G Android Development] Sinful Animosity:
Haha that's exactly why I'm not worried. Thank god for that unlimited goodness.

I'm really loving this kernel. It only gets better from here. :)
[Atrix 4G Android Development] zcrugby:
thanks. i thought so. still waiting on wifi :( but great work on this kernel :) cant wait for it to become more stable (well for the wifi to work) :D
[Atrix 4G Android Development] djkinetic:
Here's hoping moto open sources the 2.3.4 kernel soon although i''m not holding my breath considering the update hasnt gone official yet.
[Atrix 4G Android Development] DarkRyoushii:
seem to be getting quite a few force reboots. I'm using KennethPenn's Gingerbread 2.3.4 latest beta 4.5 with 1.77 radio.

Cleared cache partition and davlik cache in CWM. it seemed to die when granting su permissions to root explorer. as well as preparing internal storage as soon as the phone starts
[Atrix 4G Android Development] djkinetic:
no force reboots or closes for me just the eternal wifi wait
[Atrix 4G Android Development] faux123:
For those of you who experienced random FC, reboot into CWM and do a Data Wipe / Factory reset (I tried wiping cache, but it didn't work).

Yes, you will lose all your data, but this will fix the random FC loops. I believe this is caused by data corruption from either CWM and/or Busybox commands. After flashing zip updates, sometimes the /data partition gets corrupted which leads to random FC loops.

PS: @ work right now... Tonight I will spend more time on the WiFi issue. I will investigate the difference in source code to see why the WiFi scan failed most of the time.

PPS: Atrix's clocking scheme has changed quite a bit, currently it's in between the old Shmoo Version (LG G2x/Optimus 2x) and the new Tablet versions (like Asus, Xoom etc). So the tablet OC scheme won't work on it neither would the original FakeShmoo version... I am trying to figure out how to tweak it for higher frequency and lower voltage.

Great Kernel man Everything runs smooth and fast 4 me also...As far as wifi i left it on for a lil bit and everything was all good....
[Atrix 4G Android Development] OSNPA:
About the wifi- people are reporting wifi takes a while to connect, would that be every time it connects or just to initially set up wifi services?
[Atrix 4G Android Development] Gandalf:
To users who have applied this kernel to their 4.5.91 phones, how is battery performance / life being affected?

Also, if i decide to switch back to the stock kernel,

i simply follow the same installation instructions for the custom one, but replace the customized kernel with the stock on in the commands. correct?
[Atrix 4G Android Development] ahmarchi:
i believe its every time the phone is started/rebooted... once its booted and the first scan comes through, its scan normally
[Atrix 4G Android Development] tassadar898:
ive been tweaking alot with pimpmycpu and i can say for my tegra chip 1.1ghz @ 1050mv and 1.2ghz at 1150mv should be stable for most (i have a sample size of 2 :P). personally im stable at 1.1ghz at 1000mv. Also a 25mv reduction on the 1ghz step.
[Atrix 4G Android Development] DarkRyoushii:
Hey,

Just to clarify before I go and wipe all my apps/SMS messages again for the forth time this week, formatting /data will stop the force REBOOTS I'm experiencing too? you say Force Closes in the post but quoted my force reboots one so I was confused.

Thanks in advance

Best benchmarks I have ever gotten with my Atrix. Great work!!!
[Atrix 4G Android Development] CaelanT:
Thanks for the hard work you put in Faux.

Clemsyn's kernel works extremely well also. Any chance you two will collaborate on a super kernel? I have a feeling if both of you worked together that the end results would be astounding.............not that both kernels aren't great already! :)
[Atrix 4G Android Development] Notorious544d:
Clemsyn's kernel is based on Faux123's kernel anyway but has further OC'ed the GPU and AVP.

Btw, Clemsyn is apparently gonna try a 1.6Ghz OC.... :eek:
[Atrix 4G Android Development] s1mpd1ddy:
flashed it this morning for CM7-b2f -- seems fast so far, but the previous kernel allowed me to undervolt a lot more then I can undervolt now.. will need to check what I can do now.
[Atrix 4G Android Development] sk8trix:
Why is the 1.3 ketnel gone?
[Atrix 4G Android Development] Vangelis13:
There's an enhanced 1 GHz coming and that's it I'd think. Use the 1,45 one and set the speed you want through set cpu or other equivalent app, it now sticks to that speed.
[Atrix 4G Android Development] CaelanT:
I know. Been running it since he put it up. What I am driving at is we have 2 different devs developing essentially the same kernel with their own ideas of what is the best optimization. A collaborative effort might give us the absolute one and only best.
[Atrix 4G Android Development] Vangelis13:
+1 That'd be great!
[Atrix 4G Android Development] sk8trix:
How is the battery compared to the 1.3 kernel?
[Atrix 4G Android Development] treehumper:
Clemsyn doesn't own an Atrix, he just put the kernel together for a friend. The fact that he uploaded it was just sheer generosity. He said if he gets a hold of his friend's Atrix again he might get it to 1.6 but that is still a heavy dependency. I wouldn't suggest any collaboration because of that dependency alone.
[Atrix 4G Android Development] andyman_187:
awesome job on this kernel! many thanks! quick question though, does the new 0.2.2r have the built-in thermal protection enabled already? my atrix gets quite hot when running at 1.45ghz but is blazingly fast (w/ Ba2Tf). I'm currently running it @ 1.2ghz w/ -50mv across the freq. range, any lower for me and I get reboots. Battery life seems to be slightly better than the previous kernel, now I'm getting 1% drop per hour w/ wi-fi on (previous kernel used to be 2% per hour) and I get no more intermittent sleep states. Bravo!
[Atrix 4G Android Development] totti123456:
does the new version solves the dissappearing widgets problem? i tried 0.1.9 to 0.2.1 and almost every rom. Only on cm7 seems that issue is solved or with any other rom + stock kernel from this thread
[Atrix 4G Android Development] newalopez:
Tried locking @1ghz, but it's slower for everything, linpack single thread is faster than linpack multi-thread (40 to 35), same behavior as trying linpack with a single core device, if I set setCPU @1.2ghz, then does fine, 50 to 75... on 4.5.91.

Will use @1.2ghz for a while.
[Atrix 4G Android Development] Notorious544d:
Has anybody tried Webtop with 2.2? Apparantly the frequency shouldn't lock up anymore.

Plus it'll be interesting to see the performance of ZRAM.
[Atrix 4G Android Development] Phalanx7621:
Wow. Great scores on cm7 very snappy.
[Atrix 4G Android Development] faux123:
Yeah, my source is completely open, I am sure if Clemsyn found a major bug or have done major improvements for it, he is more than welcome to submit pull requests via github or send me PMs. This is what open source is all about. Everyone can make improvements then submit pull requests to make it even better for everyone else :D
[Atrix 4G Android Development] Vangelis13:
Aren't you supposed to be in bed drinking hot whisky..?! :-)
[Atrix 4G Android Development] dulexetina:
+1 I wanna know also about widgets
[Atrix 4G Android Development] Notorious544d:
Just to let you know, people are reporting much better GPU performance on Clemsyn as it is OC'ed to 400mhz but also found that maybe the GPU OC wasn't working properly on your kernels.

I also found that in 3d benchmarks, the results were more or less the same for both 1Ghz (w/o OC) and 1.3Ghz (w/ OC).

I think it may need a little looking into as there should be quite a significant performance increase from 300mhz to 350mhz.
[Atrix 4G Android Development] fleurdelisxliv:
ive had no widget problems and for some reason my battery is way better than when i was on the enhanced kernel. oh yea and my cpu temp hasent been over 52c 123f at all. usually in the lower 40s undervolted at -100 for all :) thanks faux!
[Atrix 4G Android Development] Antzor:
You are a hero and quite possibly a god, can't wait for the enhanced 1ghz for cm7 :D This kernel has been AMAZING for this phone, seriously.
[Atrix 4G Android Development] faux123:
Oh... I am not aware of it.. no one has officially reported my 3D OC being broken... BTW, 1.0 GHz version has its 3D OC'ed as well, that's why it's called "enhanced" ;)

Yeah, if you found an issue with it let me know or point me to the right direction, then I can make updates and changes if necessary.

[Atrix 4G Android Development] faux123:
The current nvidia DVFS code has thermal throttler (TT) built-in but it's either broken or not activated. I also have my own thinking about thermal management as well..

DVFS is

SO damn complicated

... I still need to wrap my head around it... I will either fix the existing TT or if I can't fix it, I will implement my own in the next version.

With CPU freq properly fixed and with UV, you should have better control over thermal management for now..

[Atrix 4G Android Development] CaelanT:
Observations between Faux v0.2.2 kernel and Clemsyn's elite kernel. ( I am not knocking either kernel, only relaying what I see personally):

I had Clemsyn's kernel flashed right after it was posted. I was on Faux 1.0GHz stopgap prior to that, and found it the best to that point. After Faux posted 0.2.2 I flashed that and immediately found a difference in the response time of my phone between the two. Not knowing/understanding exactly what all the differences are I can only point out what I observe through normal use on my phone.

Both kernels are/were running at 1.0GHz and UV'd on all values at -100.

With Clemsyn's kernel my phone wakes up immediately with no lag. The FP reader is immediately responsive. With the Faux kernel there is some lag, sometimes several seconds before I can swipe the FP reader to unlock.

Once the phone is awake it feels generally more responsive, faster and snappier when swiping through screens and opening/closing apps on Clemsyn's kernel. On the Faux kernel there is minor hesitation/pauses when opening apps, and a wee bit of jerkiness when navigating through home screens.

I ran speed tests on both kernels at 1.0GHz and at 1.45GHz and 1.4GHz respectively in both Antutu and CF Bench. On CF Bench I get the scores very close with both kernels at both 1.0GHz and at max clock speeds. Nothing major to report there. With Antutu however I cannot get the benchmark to complete on the Clemsyn kernel. My phone always locks up on the last graphic benchmark and I have to pull the battery. When on the Faux kernel I have no problems completing Antutu at either 1.0GHz or 1.45GHz, so something is definitely different for me there.

Regarding temperatures, I am seeing no real difference there either, so nothing major to report. I am around 32C at idle/screen off and run to around 52C under load at 1.0GHz on both kernels. At max clock speeds I am in the 60's on both under load, and around 41C at idle/screen off.

From everything I see on my phone, the major difference between the two kernels is in response time. Everything else is very much the same.
[Atrix 4G Android Development] naset:
