I have a strange problem with 4.8 nightly kernel. It won't boot (first boot after updating rom) with AC charger connected with battery @ 100%.

Can someone verify that condition?
[Motorola Droid RAZR] dubisz:
AFAIK it's normal generally for kexec roms - sometimes they don't boot for the first time and get stuck after the kexec vibrate. The battery level's got nothing to do with it. Unless you've got a different problem.
[Motorola Droid RAZR] Brantuck84:
I can confirm that the kernel will boot I ran it on 3 diff roms yesterday though it made my phone stay very hot and 4g doesn't work

[Motorola Droid RAZR] mat9v:
That's different situation. It would not boot at all, tried that 5 times or more. Once I disconnected AC it booted all right without problems. It's not a problem but may be a symptom of something wrong in rom or kernel config....

---------- Post added at 04:41 PM ---------- Previous post was at 04:38 PM ----------

Did you try that with battery @ 100% after flashing rom?

Could you try clearing dalvik/cache and boot with AC connected and battery @ 100%?

[MENTION=4287139]dtrail1[/MENTION], is there any ETA for the unifying of these 2 great kernels? I'd love to have it, since I want to keep it low powered while I'm still can get it's raw power :D

Even right now I'm using your 0.4.7 OCE but keep it UV'ed to 875 mV at 300MHz + sakuractive governor that keep the freq low and mostly use only one core at a time.

Anyway, I've been 2 days at honeymoon with my Maxx after found the culprit of all the lags I were reported previously : it's my ROM's minfree (Liquid).

Thanks for your hardwork, keep it coming!!!
[Motorola Droid RAZR] mat9v:
0.4.8 nightly is unified.
[Motorola Droid RAZR] ryankliber:
I installed carbon on bmm system_2 yesterday without your kernel. I was able to reproduce the minfree lag issue, it was pretty difficult but it definitely is the rom and not the kernel.

The OP recommends all kexec roms, and the kernel to be installed on system_1 if using bmm. Well I'm on 2 now, not experiencing any crashes or instability, so I am going to try backing up and flashing probably the 0.4.7 oce. Hopefully I don't have to switch to system_1 to use this kernel and have it stable. I'll report back with my findings.
[Motorola Droid RAZR] Brantuck84:
So I'm running the 5/22 carbon nightly with the oce 4.7 and guess what..... Its running real damn good. No lag no memory issues everything is good so far I've been running for about 7hrs now I'm not sure what changed in carbon but it helped. I'm clocked at 1458 with sakurative gov and sio+ sched

Edit: I just went through my app drawer and opened app after app then hitting home so that they stayed in recents and still am not experiencing any lag what so ever

[Motorola Droid RAZR] megawebmaster:
I have a question - as some users (like me i.e) wants only info about what's going on with the kernel - [MENTION=4287139]dtrail1[/MENTION] maybe you can create new thread without discussions and post changes there? We can ask mods to pin it (as we have currently only one heavily developed kernel) so we can get all information we need from one thread.

As for the kernel - I'm using 0.4.7 for 5 days and I'm pretty astonished how well it manages battery, BUT I have some lagging. I cannot find the reason for it: sometimes it works as it should and sometimes I have to wait after waking up my phone or to load app, many times Chrome was so slow Android thought to kill it and asked me if I want to wait or kill the browser. The other thing - I cannot change minimum frequency in Trickster, but I can max for screen off. And last but not least - I've experienced 2 incredibly heavy battery drops - for first two times charging the phone it behave as it should to around 50% of battery and then dropped immediately to 15% (I haven't saved screenshots, sorry). I've checked using BBS for the details but found nothing.

I'll use the stock CM kernel for a while to see if these lags are caused by kernel or by system itself.

Using: OG RAZR, CM 10.1 RC2, BSE 0.4.7
[Motorola Droid RAZR] dubisz:
Here are my last battery stats - first charge after LiquidSmooth update to 2.4. Using BSE 0.4.7. Not a lot of screen on time, some calls, some messages, a bit of wifi. 2G/3G. As you can see, I've undervolted to 850 mV. I didn't get even a single freeze or reboot - everythings running smooth and fast. Using hotplug and sioplus. On the second charge I'm going to change scheduler to sakuractive.

Edit: Scratch that - just went down to 840 mV.
[Motorola Droid RAZR] emiliobadillio:
I'm trying to find the auto memory manager to adjust the minfrees in rom toolbox and don't see it anywhere. Where can I find it?
[Motorola Droid RAZR] ryankliber:
Pick task manager then pick the little graph with the heartline on the very top left of the app

Edit: full wipe and flash of 5-22 carbon and they still didn't fix the memory lag that others mentioned was fixed. Set minfrees and installed 0.4.7 oce and set sioplus with the stock performance settings. Been running great for a few hours, oh on system_2 in bmm btw :D
[Motorola Droid RAZR] mat9v:
I hope you don't mean you are using performance governor? Your battery will be dead in about 6-8 hours that way :)
[Motorola Droid RAZR] ryankliber:
That's about how long my battery normally lasts haha, and I said exactly what I meant.. Only thing I'm changing related to the kernel is sioplus for the scheduler, gov is still on hotplug.
[Motorola Droid RAZR] dtrail1:
Here's my review about the latest Hybrid Kernel.

I have used the phone for about 12,5 h, now there are 50% of battery left and the screen reached 2 hours of runtime. If I let the phone somewhere in my room it drains about maximum 10% over a whole day (data & wifi is OFF while screen if off). In flight mode it drains 2-3% over the whole night.

What is the JBX-Hybrid-Kernel?

- A hybrid of BSE and OCE (Has 100mhz min, and 1350mhz max)

- A hybrid of other kernel versions (3.0.64, 3.0.31, 3.1, etc)

- It includes some driver backports from higher kernel versions (It did also before, but I included some more)

- Many patches for battery life, performance and features

- It comes as JBX-Kernel 0.5 (already online in NIGHTLIES)

As someone already stated, the minfree-mem-bug comes from the roms, not from the kernel. I did a lot of research and couldn't find a reason for this in my kernel. So I think these roms own kernels may include other values which are working well, so my kernel mightn't play well with it. But I hope this problem isn't present in 0.5 anymore.
[Motorola Droid RAZR] dubisz:
Looks nice - upgrading now! :]

I still have the same problem, I can not set IO with version 0.5
[Motorola Droid RAZR] dtrail1:
It seems that there is aproblem with your device, not hardware but software. As I know everyone can set IO. So try the following:

- Open Trickster App Settings

- Delete Cache and Data

- Uninstall Trickster Mod

- Manually remove/delete EVERYTHING related to Trickster using root explorer or similar app. Search in /data/data and data/app-data and /data/asec, etc. Delete each file which belongs to Trickster.

- Now reboot and wipe cache/dalvik cache

- Install the latest Trickster Mod from Google Play Store

- Try to set IO
[Motorola Droid RAZR] dtrail1:
Is there anyone else who cannot use 4G? Does it work with your roms default kernel? Actually I didn't change anything related to mobile data network...

[Motorola Droid RAZR] stigers:
[MENTION=4287139]dtrail1[/MENTION] I noticed that official CM 10.1 had made some changes to the kexec kernel, hope your OCE BSE kernels could keep pace with them.
[Motorola Droid RAZR] ryankliber:
I can't find a 0.5 in either the nightly folder or the kernel folder, only thing in nightly is 0.4.8.

Edit: (carbon 5-22) now that i found 0.5 i flashed it, running great with 4g for about 5 minutes, then a full loss of mobile network. i tried switching to 3g, and toggling airplane mode, and nothing. Then i tried rebooting into recovery and wiped cache, dalvik cache, and fixed permissions. booted it up and everything worked for about 5 minutes and then a full loss of network connectivity again.

[Motorola Droid RAZR] romdroid.:
Have anyone tried OCE kernel with 1.5ghz does it run stable? I am tempted to OC but how is battery life when in 1.5ghz?

and also can someone tell me how much battery life u are getting with bse?

if I understand things right, bse is for battery saving and OCE for OC?

Which version do u guys recommend for CM 10.1 RC2?

many questions but I hope somone will take their time to answer them :)
[Motorola Droid RAZR] dtrail1:
OC runs fully stable. Battery is not much more bad than on BSE kernel. But there won't be BSE and OCE anymore soon. I am merging both kernels into one, that's easier to work with and users can set it to battery or performance by selecting their preferred frequency.

Just use the 0.5 NIGHTLY, it's the first merged hybrid kernel. As long as you aren't an lte user it will run well (breaks lte connection atm - I'm fixing it).

Otherwise use 0.4.6 or 0.4.7 nightly.

Edit: Kernel Restore zip is online again. Link fixed.

Thanks is the hybrid stable for daily use or should I wait a couple of days?

There is both a features list, and a changelog in the OP.
[Motorola Droid RAZR] dtrail1:
Do you guys know what I love in development???

Das

It took me ONE WEEK to find out what was breaking the kernel boot process and why I couldn't set a big frequency table anymore. So, there are around - I don't know how much, but maybe about 100.000 files (?) inside the kernel source. And I had to find the ONE SINGLE file which was responsible for the broken kernel, and inside this file, besides of its included 10.000 letters, the ONE SINGLE letter which was causing this break! So, I found it!! It was just a change from a "8" to a "15" :D :D :D ...ONE WEEK!!!!!!!!!!!!!!!!!!!! ARRRRRRRRRRRRRRRRRRRGGG!

After this phenomenal happening I'm now testing the new hybrid kernel. It has MANY fixes! Battery life has been greatly improved and the performance it has was unreached until now.

Within the last 7 days I found many mistakes, like typos, wrong definitions, bad configurations and much more.

I also did a lot of fixed and improvements.

For example the whole cpufreq policy got a workaround and governors are now fixed. Because of a stupid typo there were 5 governors with different names, but in fact they were all the same one governor :D

So, hyper is now hyper and adaptivex is finally adaptivex :D

A very big difference! Hyper causes bad performance but greater battery life.

The new lulzactiveW provides great performance.

The new frequency table is BIG - and fully working! Because of its size the scaling if smooth and it runs more on lower frequencies. It's a true hybrid of BSE and OCE with the great stability from the last nightlies. Frequency starts at 100mhz and is limited by default at 1ghz. But 1,35ghz is also available for your choice.

The issues which set the user cpu settings back after screen off has been fixed finally!

But this kernel is also a true Linux kernel hybrid (moto did this too). It includes many backports from 3.1 and other kernel versions. Because of that it's more difficult to patch it to higher main or sublevel versions.

That means, the kernel version shows 3.0.8+ but it includes parts of higher versions. I have modified some drivers, like wifi, net, cpu, etc and it seems working. I guess I could fix the lte issue by the way.

The kernel has reached a very stable state, so I don't append the local git hash string anymore. It's just 3.0.8+ now.

I've learned a lot more about C code and it's possibilities too. Now it's more easy for me to work on it.

Stay tuned and watch out for the today's release. I really hope that it's that stable for you guys too.

[Motorola Droid RAZR] romdroid.:
I just checked the feature list in OP and I was wondering if Wifi is better with this kernel then cm 10.1? Because my wifi signal is pretty bad, I move away from the router and it drops to 1 bar and then suddenly wifi dies.

Also what tips do u have for a casual user who want to save battery but still have performance? I will try the hybrid kernel
[Motorola Droid RAZR] dtrail1:
Current hybrid kernel will break your lte connection - if you use it.

The today's release will be a very improved one... So don't miss it then. I want as much people as possible to test it! Release will be in 1-2 hours.
[Motorola Droid RAZR] brainwash123:
Maybe someone already answered this and I'm late. I'm just getting up to date with the thread.

I got this symptom especially with OCE roms and it seemed to happen more often as the phone was getting hotter and it was connected to AC/USB. My recommendation is that you charge the phone to 70% or more and install the roms with a cooler phone and no charger. Sometimes I was able to boot first time OCE after 5 or 6 tries. I also did reflashing of the zips in between, but I don't think it really helped. It's just a thing that happens.

Edit: just forgot one thing: especially after installing a new ROM or/and kernel you should not keep the phone plugged in while it is doing its initialization stuff. At least on my phone it seems that with a full battery somehow the stats are messed up and the phone tries to charge the battery even more, causing it to get extremely hot. You WILL destroy the battery this way.
[Motorola Droid RAZR] romdroid.:
afaik xt910 does not support LTE in europe, so that is no concern for me :p

also is wifi in ur kerlen better than cm 10.1 kernel?
[Motorola Droid RAZR] dtrail1:
Don't know. Why don't you just try it and tell me, instead of asking thousand questions? :P *joke*

Yes, I know we don't have lte. But I didn't know if your own a 910 or 912.

And in fact we have the lte chip inside our device. The driver works and it's initialized on boot. But our roms don't support it and the baseband drivers doesn't use it. And if we'd be able to use an lte baseband driver it still had to be configured for each country's lte frequencies - they're different from US ones.
[Motorola Droid RAZR] romdroid.:
wow that would be awesome if we could activate lte. do u have any plans on fixing it?
[Motorola Droid RAZR] dubisz:
Can't wait! Keep up the great work!
[Motorola Droid RAZR] dtrail1:
You misunderstood. It's not possible so far. There are no EU LTE Baseband drivers available and we cannot flash a custom baseband. Not sure if we could run it from somewhere else using kexec kernel to define another place as baseband partition? Not my skill..
[Motorola Droid RAZR] Jack'O:

[Motorola Droid RAZR] dtrail1:
Of course my mistakes - but also some code which could be replaced with better one ;)
[Motorola Droid RAZR] dtrail1:
AGAIN:

IT'S NOT POSSIBLE!

I have clearly stated that in my prior posts.

Kernel Update:

It took some more time, sorry. I have built in my first self-made feature, ported and modified from an existing interface. It allows users to tune the smartreflex maximum scalable voltage for each deps (mpu, iva, vdd), which could be useful for overclocking - but also should be used VERY CAREFULLY. Maybe I should set an max limit that nobody can burn the board... FOr those who think now that this can be done in custom voltage: Custom Voltage controls the fixed, non-scalable voltages. If you turn off smartreflex it will stay on the defined values and this usually results in higher power consumption. TO clarify what smartreflex does: It scales up/down voltages for each frequency scaling step (whether it's cpu mpu, display or gpu) in realtime. It calculates an optimal voltage value for the current power state and is able to change the voltage for an OPP within a given range. The new interface should make it possible to keep smartreflex active, also on higher freqs than 1,5GHZ, and helps to save power.

The only disadvantage at the moment: It is not supported by Trickster Mod or any other app, because it didn't exist before. But i will contact Bigeyes0x0 and ask him to include it for us - he's even a very nice guy, answering all my requests! :)

I've done a lot of more fixes - mostly my own mistakes and some more things to get the CPU running stable with the new OPP count. There was an commit by Hashcode 2 weeks ago which helped increase the kernels stability but suddenly the kernel was not able to boot with any OPP count higher than 7. SO I had to sort out many commits, did reverts, did revert-reverts and confused myself sometimes :D But I could find the reason and hopefully everything is done for now!

A full changelog will follow soon. First I have to verify the kernel runs stable now.

Made the transition to Boot Menu Manager today. So far, I'm really happy with it. There are things I like better about Safe Strap, but having to regularly boot into recover after a boot freeze, select stock rom, allow that to boot all the way, back to recovery to switch again and then probably be able to boot my rom - Gah! that was horrible (and I had to do it several times a day. Any time I had a freeze or random reboot from changing a kernel setting (or whatever) I would have to go through that little routine).

So far, BMM just boots right up - Awesome! I know this comment isn't exactly kernel related, but I was getting so frustrated testing a new kernel release and any little reboot or problem locked me into the 5 minute Safestrap dance, now I feel much more free to experiment. Thanks [MENTION=4287139]dtrail1[/MENTION] for recommending BMM earlier in the thread!

I'm having a small problem with music playback.

Here are the conditions:

-Poweramp player

-governor - sakuractive

-scheduler - sio+ (2048+ buffer)

-Multicore Power Saving - 1

The problem is intermittent skipping of sound. When listening to tracks with screen off every few minutes there is a skip in sound less then 1/2 second in length. The remedy seems to be decreasing scheduler buffer to 1024KB or less. If I change the buffer size while listening to a track I am certain to hear a skip after some time depending on the buffer size - seems like after emptying the buffer the skip is heard. That is not to say that this is only one skip, it will happen again and again after few minutes - maybe equal to the buffer size. On the other hand if the buffer is set to 1024KB there will be no skipping. Changing to other schedulers does not fix it, only changing buffer size. I will try other players to verify if it is maybe Poweramp problem.

Apollo player seems to suffer from that too, but in this case, even lowering buffer to 1024KB does not help, I had to go down to 128KB to eliminate skipping.
