Same here with the latest mrom ..back to v4 kernel because of better battery life than using v23...couldn't try v24 because of bootloops even if clearing everything...i observed the battery graphic that goes down more quickly than before flashing v23...at least according to me:) forgive me for my poor english!
[Atrix 4G Android Development] mmontuori:
From the posts, I am getting that build #24 was a little to aggressive as far as under clocking, not everyone can run it. But I think for the people that can run it, the battery is lasting longer. Is this a correct statement?
[Atrix 4G Android Development] badnokia:
I flashed the hardware version for CM #23 (I'm running 7.2 stable). It's been running ~13.5 hours with typical use for me & I'm down to 15% already. This is worse for me than the kernel that came with CM 7.2 stable. I cleared caches & rebooted after flashing. Any chance I'm getting erroneous battery data? Or am I one of the unlucky few without improved battery life?

Edit: 14hrs 36min, down to 3%. :-[
[Atrix 4G Android Development] fabianowerner:
I'm at version 4 cm7 release. I'm up for 30 hours with moderated usage, still have 50p percent battery.
[Atrix 4G Android Development] TravisAntonio:
That's a lot.

Post your bat stats.
[Atrix 4G Android Development] ravilov:
I think more important than the battery percentage value is how much the battery actually lasts. Atrix is notorious for having false percentage readouts, so maybe you guys shouldn't pay that much attention to that and focus on the actual battery life instead. It's entirely possible you'll get several more hours with (allegedly) just 4% charge left.
[Atrix 4G Android Development] badnokia:
I wish this were true for me, but my phone totally died soon after the 3% mark (that was less than 15 hours of typical use, which is worse than CM7 stable kernel). I'm trying the deep blue fix today. I was getting zero deep sleep. Early indications are that the fix is allowing some deep sleep despite the controversy over whether it really works or not. Am wondering if I'd have better luck with the CM software version. Can anyone report if the boot loop issues with that version (#24 I think) have been resolved?
[Atrix 4G Android Development] Pinktank:
I consistently get 48-56 hours with 3 1/2 hours of screen on.
[Atrix 4G Android Development] badnokia:
Which version of the kernel, and if CM, which version? I want your battery life! :)
[Atrix 4G Android Development] mmontuori:
Kernel

I understand that the general consensous is that HV kernels are unstable and SV causes bootloop on some devices. I am working on a new version which will have the voltages adjusted that it would work on any devices, and pretty much trashing the HV.

Issues, concernes, or comments?
[Atrix 4G Android Development] alberto88a:
As I've already said, according to me v4 is more energy efficient :) still 78% after about 10 hours of normal usage: not often used data and wifi, some calls and sms...about 20 minutes playing games :)
[Atrix 4G Android Development] badnokia:
I'll happily try your next build. HV#23 on CM 7.2 stable had poor battery life for me, but otherwise seemed stable. Looking forward to it!
[Atrix 4G Android Development] Zeljko1234:
Please don't trash the HV. It only works for me and v23 works very well. I'm still testing to see battery efficient but looks promising.
[Atrix 4G Android Development] mmontuori:
Kernels

Hi All,

I think it's obvious that kernels and battery work differently for each one of us and strictly depends on the configurations we decide to run. What is not efficient for some is very efficient for others and vice-versa.

Bottom line, all versions will be available on the web site for you to download.
[Atrix 4G Android Development] Pinktank:
I am using the ops MROM. Data off, a lot of wifi, you can get better with wifi off

[Atrix 4G Android Development] android-DEP:
Mike, are you in a PhD program or something? That paper about time inflation and time deflation is on some next level beyond the next level reading material. Did you take aderrall when you wrote that paper? I couldn't make it past the first paragraph, I was lost and couldn't stay focused anymore to try to keep up with what you're talking about. I never seen anything like that before. Very interesting project to investigate though, how did you get involved with that subject?

---------- Post added at 10:02 AM ---------- Previous post was at 09:52 AM ----------

webtop will not work. CM7 based roms only provide the ability to mirror over HDMI in portrait & landscape. Webtop is not native to CyanogenMod roms and therefore unavailable to users running any CM7 based roms. It's just a feature that was never included in the main project as it's simply a collasal battery drainer, slow internet browsing, limited functionality, takes up A LOT of space on the phone and adds around an extra full 5 minutes by itself if include in the installation of a rom. All in all it's pretty much useless, being able to mirror over hdmi without a dock is really the way to go if you want to connect to a bigger screen. Webtop really is useless, I lost my webtop for a long time and last week decided to get it back and missed using it. After 2 or 3 days, I couldn't wait to flash my phone to get rid of it, it ruined my phone's performance so much, I notice the difference immediately now being back to my own CM7 rom with all the bloat removed and anything useless taken out. The phone works beautifully and battery life is phenomenal once again.

Just wait until Webtop 3 gets released, thats the next generation of the Webtop and will bring great features with it that are useful
[Atrix 4G Android Development] mmontuori:
android-DEP, that was funny, I am not in a PhD program, I am glad someone is reading it, one day, in 2003, I had a vision about what would happen travlling at very fast speed, look at the current theory, and they seamed to have left out some very important details. The funny part is my next theory, variable light speed, I don't think anyone is ready for that kind of stuff.
[Atrix 4G Android Development] jisse44:
Dont think like you. I use webtop for work and at home. its essential.

If dev put a GB kernel, webtop must work. Like Faux kernel

Webtop 3 seems to be an useless tablet mode for me, not a full uptodate Linux....
[Atrix 4G Android Development] mmontuori:
Sorry that GB kernel does not work for you, I would gladly work on it, however, I don't own a webtop; this makes things hard for testing... but I will see what I can do.

Do you know if the webtop has an assisted processor like x86 or powerpc, that might be the reason why?

I also need logcat dump when you are connecting the webtop and the actual error you get back, that would help. Just saying it does not work does not help... help me help you...
[Atrix 4G Android Development] jisse44:
Webtop is an Ubuntu Jaunty compiled in armv7, running inside the Android.

Webtop is not Lapdock, I think you mix up. You can launch Webtop simply by plugging micro hd cable to tv or screen.

Ill try to get some logs tomorrow.

[Atrix 4G Android Development] Nipit:
Yeah, I know it's all great, but... What's the point in creating 2.3 kernel? The firmware is already old, it had it's time. The real question is if anyone can create 4.0/4.1 kernel.
[Atrix 4G Android Development] jisse44:
And real answer is no. Not until sources came out....

The point is to increase battery life and other mods and tricks

Send from my Atrix 4G
[Atrix 4G Android Development] Zeljko1234:
What's the point of your post? If you think that you can do better, come on, create 4.0/4.1 kernel. If someone spend his own time, knowledge and share with us for free than show some respect.

My Atrix with almost stock GB works much better with this kernel, better battery life, less wake up...

You tried using the beta kernel yet and making a 1ghz version. Faux says its got better deadlining etc

Build 29

I have posted a new release of MROM containing my latest kernel build#29, I really tried to create something that would suite everyone. MROM has exclusive use of the kernel for now, but soon I will release it as a separate download.

If you happen to run MROM, please provide feedback on build#29.
[Atrix 4G Android Development] Zeljko1234:
As I promised, I've just made small donation. I'm so satisfied with your kernel (v23 hw) with almost stock GB.

Thank you very much.

Bug Reports

Hello,

I would like really like to help you in resolving the problems you are having with MROM, but I need a little help from you, just putting a message here saying "it does not work", it does not help me understand what the problem is.

To report bugs, follow these steps:

Install ADB (Google SDK) www.android.com for reference

Connect your phone to USB (Make sure USB Debugging is set)

run "adb logcat > {somefileonyourpc}"

Reproduce the problem

Press CRTL+C on your computer

Open a Bug Report, the link is on the main thread.

Make sure to attach the logcat file, a description of the problem, and the time it happened

After that, it can be tracked and I can ask additional information to solve

Without this information, it's difficult or impossible to help.
[Atrix 4G Android Development] Zeljko1234:
I recommend to put this guide in first post and your web page.
[Atrix 4G Android Development] mmontuori:

Problem flashing the software voltage kernel...

EDIT: Sorry I see that the issue has been addressed already.

I flashed the sv kernel and rebooted. Had boot loops and freezing. Recycled and cleared cache and dalvik. Boot loops again. Reflashed and cleared caches at same time. Froze again at Motorola screen.

Flashed hardware voltage (hv) kernel and cleared caches and was able to fall back successfully.

As I was trying to derive stable Undervolt values I do not set the voltages to run at boot so that shouldn't be an issue. I always loaded a saved voltage in neutrino via system tuner pro.

Was anyone able to flash the sv kernel?
[Atrix 4G Android Development] martyman19828:
23hv is very very good. Best battery yet.
[Atrix 4G Android Development] flaviocc:
:confused:

everything was ok...but.....2 nights ago my phone doesnt go in to deep sleep......and i dont change anything....
[Atrix 4G Android Development] mmontuori:
You probably have something running preventing the phone from going in deep sleep, try to use System Tuner, possible pro, so you can record activity in the background to see which process is using cpu all the time...
[Atrix 4G Android Development] Zeljko1234:
I found problem, disadvantage of the MROM great kernel. During charging, CPU runs 420 MHz all the time. I was wondering why charging takes so long and found that CPU spends part of the current. I still use v23 hv with GB rom. With stock or faux during charging frequency is 216 MHz.

Another one is with SportsTracker. With previous kernel, during tracking CPU runs 216 Mhz, even with music player. Now is about 300 MHz then 216... Probably is worse for battery than before. But this kernel has much less awakes. Almost without any with screen of instead any other kernel. What is, of course, great for battery.

I have screenshoots for both cases. First one is Sports Tracker, second charging.
[Atrix 4G Android Development] mmontuori:
Thanks for submitting your findings, I was already aware of this problem and my next kernel should address them...
[Atrix 4G Android Development] Zeljko1234:
Thank you very much for fast respond. Could you explain technical reason why this happens?
[Atrix 4G Android Development] mmontuori:
Using more the 300-420mhz frequencies is due to the fact that the native governon prefers it over the 216 because the scale is not quite right. The charging frequency, again is dictated by the hardware governor, faux kernel exclusively uses software governors,... Hope this answer your questions.
[Atrix 4G Android Development] Zeljko1234:
Thank you. Actually I changed governor to powersave. It helps during GPS tracking but not with charging.
[Atrix 4G Android Development] mmontuori:
Kernel #32

I was asked to release the kernel #32, which is currently powering MROM. You ask and you shell receive!!! See main post...
[Atrix 4G Android Development] RoboDroid13:
Thanks for your work here and on the atrix mmontuori :good:
[Atrix 4G Android Development] Zeljko1234:
Did you solve governor scale problem? :)
[Atrix 4G Android Development] mmontuori:
I don't think I would call it a problem, it's more of a behavior... but have not had much time to dig in the code... you got to have a certain clarity before changing that code...
[Atrix 4G Android Development] Zeljko1234:
OK, did you solve this behavior?

For me is a problem. I cycling a lot and track my route. Higher CPU frequency means more battery drain and less cycling :)
[Atrix 4G Android Development] mmontuori:
You may want to try, I did make changes to the frequency scale, it should scale better, for the charging at the second lowest frequency I have not looked at that one yet... with this kernel, people are reporting very high battery life...
[Atrix 4G Android Development] Zeljko1234:
I'm abroad now but I'll try and let you know. Thank you :)
[Atrix 4G Android Development] Zeljko1234:
mmontuori, I don't see v32 for GB rom or I'm missing something? Do you have plan to release GB version?
[Atrix 4G Android Development] mmontuori:
I could only release CM7 quickly, GB will be up shortly...
[Atrix 4G Android Development] sathelate:
I have a huge question here for you, I've always used 032 1.3ghz faux kernel, wich is awesome downclocked at 800mhz .... i put it up on a week time schedule at 1000mhz when im at work and i need my phone to be really fast .... and occasionally to 1.2 ghz ... but all my 3d gaming is on a 800mhz normal profile no undervoltage ... I'm using setcpu and i LOVE to have control over the overall speed of my processor to avoid having over 60 celcius on the CPU on heavy gaming and i found that once the game is loaded, there is absolutely no lag, everything so smooth :D

So, that being said, I've always been scared to try Tue clemsym one (sorry if i misspelled it) cause the gpu got overclocked too, and I'm the kind of users who pass like 5 hours a day with screen on doing different things and i want my phone to last long cause i LOVE my atrix!

Now, to my questions : will this kernel going to get me control with setcpu?

And for the battery life, what did you do ? I mean, will i noticed something at the fluadity level?

will it be as fast as 1.3 ghz kernel downclocked to 800 ?

And last, for kernel newby users, what is the difference between hw powered or sw?

And i guess i have to wait a little for this #32 build, to be available on cm7 in sw mode, wich lead to my question, what is the differences ?

Many thanks for your hard time answering my questions :)

P.S. If you don't have time to answer those all, just answer about the difference between the sw driven mode and the hw and i will try and report back :)
[Atrix 4G Android Development] mmontuori:
I will try to answer all your questions:

will this kernel going to get me control with setcpu? Only frequency, even though some users reported that the frequency is not followed all the time.

And for the battery life, what did you do ? I mean, will i noticed something at the fluadity level? You should not see any difference, but I will let other users answer that question.

will it be as fast as 1.3 ghz kernel downclocked to 800 ? Not sure, but probably faster.

And last, for kernel newby users, what is the difference between hw powered or sw? hv=hardware frequencies and voltages, sv=software frequencies and voltages

And i guess i have to wait a little for this #32 build, to be available on cm7 in sw mode, wich lead to my question, what is the differences? To make the sv, I have to re-compile the kernel so more than likely will be a different build number.
[Atrix 4G Android Development] mmontuori:
GB Kernel is posted!!!

I will work on the other 2 kernels (sv) time permitting...
[Atrix 4G Android Development] sathelate:
Thx for taking time :D

So my main 2 questions is now almost answered :D

My two priority now is to be able to underclock when i don't need 1000 MHz... It could be awesome, and apparently i can do it from your answers, with maybe, sometimes, a couple of bugs :) I will test on Neutrino 2.91 and let you know :)

So, the build for cm7 #32 hw and the build 24 rw for cm7 is actually the same builds right?

And what is the differences between software and hardware driven voltages? None of matters?

Thx :P I'm just trying to documentate myself from the kind people here instead of a cold Google search about this driven voltages differences ;)
[Atrix 4G Android Development] mmontuori:
Kernel frequencies

I did some research on how the kernel sets the frequencies, when the frequency is overrode, the kernel tries its best to max at that frequency, but it spikes above 1 frequency, keep that in mind when under clocking... you have to under clock 1 frequency below the intended one. Hope this helps...
[Atrix 4G Android Development] jisse44:
@sathelate

Hi, sorry to post question here, but when I underclock to 800mhz,sometimes 3g turn off. Do you have this problem ?

Send from my Atrix 4G
[Atrix 4G Android Development] sathelate:
using faux kernel ? wich version ? wich rom ? never had any similar problem, worse is the data take idle to 3g with no data in no data out, but not fully disconnected ! did you undervolt too ? :S

---------- Post added at 02:20 AM ---------- Previous post was at 01:53 AM ----------

ok thanks :P ill keep that in minds, i just read up the whole tread, and im sorry for asking differences between hw an sw .... it was answered already, but doing an xda search gave me nothing

Allright, Soo long, soo good ! almost instant sleep !

Heavy usage since 42 minutes and the battery dropped 76 to 60 ! soo, in my head, we got to gave android a lil break after a kernel flash until all cashes is done, so the battery will stay a lil bit "calmer" but for a first report, everythimg is smooth

For technical :

HW #32 Builds

Sw : Crash at Logo twice, so can't test it right now

Web :UDP Passthrough - ok

UDA : ok

Conection through heavy load graphics : Successful in 2.8 seconds

also tried a splashtop session : Work perfectly

Wi-Fi stable : ok

Wi-Fi : No Problem so far:)

R-Reboots : None so far (NEVER had any with faux, my uptime highscore was like 36 days soo on Neutrino 2.8 b4 flashing 2.91... :D )

3G And Hsdpa here is : ok, as fast as faux

Cpu temp : was idling, screen on, after a 20 minutes game at between 60 and 62 on 024 faux 1.3 kernel, now sits at 52 with this one !

Cpu Temp : idling : 42 with anymated live wallpaper, 3 over the top app refreshing 0.5 sec, two widget on home screen every 5 seconds (was at 52, so here is 10 degrees of diferences O_O im amazed)

Reboots time chrono : 1m34 S

Fast Reboot : 37 S (a lil slower than stock 1.3 Ghz faux)

Set Cpu control : so far so good, but tried force-downclocked for like 10 minutes only

AnTuTu Bench's was : 4011 with faux 024 downclocked at 1Ghz

ATuTu Bench's is now : 5039 stock MROM HW #32 Kernel

My overall impression from a fresh 42 minutes flash (51 as im typing) is that this kernel is really promising cause it seems fast, fresh,stable and low on cpu loads cause im at 41 celcius as i type, wich is awesome for me tho (i'm a freak of cpu temp soo ...sorry :P hehe)

Will edit and let you guys know in a couple of days

Thanks Michael for this nice kernel (i believe you have the same name as mine :P)

I reset my phone, left it plugged in last night, and noticed that the lowest frequencies are being used when plugged in... So I don't think this is a bug at this point, especially for version #32.

Hi..

Mobile View in webtop and Gentop dont work for me with ur Kernel.

Keyboard dont work for me too with #32 hv.

Using Nottach Trix 1.3. 1
[Atrix 4G Android Development] Zeljko1234:
I flashed #32 GB hw today. When charging connected to computer USB, phone uses the second lowest frequency (312 MHz). Exactly what you said. Definitively better :)

With screen off and music player running, phone uses 312 MHz, then 216 MHz about 50% of the 312 MHz time. I'll test GPS tracking later.

It seams that CPU sleeps remain great as with your previous version (23).

With new kernel, good old "feature" from faux kernel came up. Widgets disappear after restart/cold boot. I tested twice.
[Atrix 4G Android Development] Neroga:
Definitely liking the #32 build better. Same voltages as the ones in #24. Better performance and same great battery life.

I'm not getting the disappearing Widgets. Did you do something different?

[Atrix 4G Android Development] Zeljko1234:
Flashed, cleared cache and dalvik, restarted, widget disappeared. Add, restart, same. But I use only two or three widgets and rare restart so it's not big deal. Just reported :)
[Atrix 4G Android Development] peddarson:
good work...seems to be really interesting.in my view the development should be more into power saving as in bigger screens.

but i don't get wifi to work with the latest release (notachtrix rom).it only says 'error'.
[Atrix 4G Android Development] mmontuori:
Regarding the disappearing widget issue, which ROM are you guys using? On MROM I don't have any disappearing widgets...
[Atrix 4G Android Development] Zeljko1234:
Almost stock, some apps frozen, modded framework, some tweaks... but with stock or your v23 kernel widgets survive reboot. I think, problem is that kernel starts widgets before storage is mounted.

As I said, not big deal for me. Thank you for new GB kernel :)
