Kernels for CM7

Hi guys im a new user of the lg optimus 2x... i only have 1 day with the phone... i installed CM7 without problems... had been playing perfect on this "little" thing... but im missing the battery profiles... i could only select powersave and performance... so... i supose i need to flash a new kernel to get more profiles and get better battery life... any suggestion?
Thanks a lot!

You could try vorkKernel, there's a thread in the android development subforum. But I had no luck with this kernel, can't get no sound output with it ...

ill try vorkKernel, hope it doesnt mess my cellphone!

vorkKernel is working fine... any suggestion for battery profiles? I want better battery life thanks!

I recommend underclocking it. However wierd this may sound, the O2X is such a fast phone anyway, so if you UC to ~760mhz, it'll be roughly the same speed but with significantly better battery life.

i used to do that with setcpu using several profiles with ondemand on my nexus one...but this lg with cm7 doesnt have ondemand battery profile!

got problems with some noises during calls... any other kernel that can underclock the cpu?

what's the best kernel? what do you use?

hey guys, id like to know whats the best kernel for you, anche which combination you use governors + i/o schedulers thanks in advance!!

FOR ME its varun's thunderzap kernel using ondemand with i/o noop

could u tell me why its the best? what do u find in terms of performance that the others doesnt have?

For me: siri kernel. Very fast and smooth. But not pegasusq governor and cwm

Best way to know what is best is to try yourself. Performance is a bit subjective feel. Trying published kernels will not make your phone explode. And it is not hard to install it. And changing governors is not hard too, just find combination that fits you. You have them explained on this forum, just need to search a bit.
I personaly like PegasusQ for governot and SIO for schaduler. Or Interactive governor is ok too.

which one u use?

At this moment, to me better kernel is Siri. Its fast and smooth. Only things what I miss there is PegasusQ governor and CWM.On other way Thunderzap is also fast, but in my opinion siri is faster. I know that in next release Varun will release much smoother and faster kernel so then i will vote for it

Try with thunderzap+smatstassV2+sio is the best configuration for me.

it also depends on your behaviour what are you using your phone for?
Gaming
Much Browsing
Phoning/Messaging/Chatting/Listening Music

Siri Kernel.
It's fast and stable.

For me the best on jb is siri. On thunderzap v2.0 and 2.5 i have screen flicker, and tochscreen was crazy

Totally satisfied with thunderzap 2.5
But only experimented "with chuck-bean master rom V3".

with a thread like this you offend the developers... the policy of xda is to try it yourself, what may be perfect for me will not suite another person

yep... there are only 2 kernels for jb and both varun.chitre15 and Adi_Pat are awsome developers so you can`t go wrong
on my old LG optimus one i was flashing ROM`s every 2 days, my friends said that i am crazy... but by trying myself i have discovered some amazing works... and now my father owns it with the latest CM 10

pegasusq in my opinion is the better governor to use, largely because it can tell if is more than one core and respond accordingly. Pair that with CPU Sleeper Dual Core and you're golden as far as power saving awareness. SIO I hear is the best i/o scheduler to use for power consumption, deadline in my opinion is the best for pure performance however be careful because If you do overload and a process misses a deadline it will hiccup or even freeze. :laugh:

Any updates?
hello i am using your kernel now for some month and it was really nice. but since some months there is no progress here. are you working on it anymore? an update would be nice after over 3 months now. I would have really some "good" additions und suggestions for the kernel. Furthermore, philz touch has a new version out. would be really nice if you could update it to the latest version. the cwm integrated to the cm11 stock kernel now is newer as the base of your last released forest kernel. Also some here have deep sleep problems. Also it would be nice if you could look for sabermod/Linaro und archi optimizations or -03 optimization of the kernel in general. thanks for your great kernel!
would be nice if you could comment short here so that your fans know that you are working on this anymore or not

That's gotta get funny... Getting my popcorn ready! ?

Too busy at work so not working on it for now. Maybe when there is CM stable or CM Lilopop....
For those who has deep sleep prob, should try disabling the sync. Use synker app to manually turn sync on/off.

i had a problem wiz cm11
Guys my battery drains very fast and i change it but the problem still happening
And after install this kernal v5 it better than the stock kernal but it use more than 25% of battery wthin less than on hour if i use wifi and just open whatsapp and browser .
If anyone had a solve for this problem ?

What exactly is the difference between the one with trim support and the one without . how do i choose which one to flash?

The one that has TRIM has TRIM. The one that doesn't have TRIM doesn't have TRIM. You can choose which one to flash by searching and reading what TRIM is, understanding the risks, and then deciding whether you're willing to take on the risk or not. Simple as that.

Am using v3 kernal for nightowl ..phones heating..but v1 is stable for me no heating and very snappy .thankyou for the kernal

Use no frills, underclock to 1.2 GHz.. Then use ondemand Governor... Problem solved..

Dear Forest, am I correct that the forest kernel beta4 in comparison to r9 is missing lcd oc?
Is there now any advantages left over r9 since cpu oc got removed?

Whats ur problem? This q+a or not?
I used v3ts until now on rr528. Since theres no b4 i switched to nightowl b4. And now Raw4 ist out that offers trim, gpu driver upd, oled oc and fpbug. I used to use forest because of cpu oc. Now that it is gone i wonder if there still is any supremacy of ur kernel that i dont see.
So what is ur problem with this question?

Why don't you just use whatever kernel you like and stop trolling?
Gesendet von meinem GT-N7000 mit Tapatalk

English is not my first language so i might not see the intentions of ur answers. I dont mean to troll. I want to continue using forests kernel and was wondering what the current state in comparison to raw it is in as these are the only custom kernels available. Since this is somehow an offence to someone dont mind anserwing this anymore. Its not an issue.

The link
The link for the downloading the kernel Forest-LP-Kernel_V4 from dropbox doesn't work. It suggests me to register on the dropbox.
I've downloaded it.

A Little Request and Questions
Greetings Forest! I am a new user of XDA, so forgive me if I made mistakes in presentation or in technical accuracy.
I am currently using your Kernel with CM11, and as far as stability goes, everything is working fine, although I find myself facing instabilities using the PegasusQ governor. Looking at the governer closely through ROM toolbox lead me to realise that there a hotplug settings existent for 4 core devices, while the Galaxy Note only has 2. Is this an issue? As far as it goes, I find myself waking up to a device showing the bootanimation continuously, but very slowly and choppy, forcing me to restart the phone. Luckily I wake up on time for work via instinct. Apart from that, the phone crashes except when using ondemand. Is there any explanation for these crashes?
Now for the requests. Since ondemand is not really the best, as I have seen more responsive and effective governors like SmartAssV2, which is personally my favourite. I've also read up on Interactive being a more responsive version of ondemand, I was wondering if you could include more governors for the kernel. Unless of course, governors are limited to CPU types which I hope not, then probably this post would've been written for nothing.
Thank you for taking the time to read this. Do understand that I am not in the field of programming, and I apologise if I made any mistakes. I look forward to your reply.

Thank u for investigating the bug and helpful report:good:. I am also testing with stock cm kernel using pegasusq and also got a freeze. Now i can recalled similar problem faced by Slimsaber. On the other hand, my kernel run well on omni and omni based. So there seems to be some issues with some governors but only happen in CM and CM based rom. I will try to fix or remove/add some new governors when I can.
For now should use Ondemand!

Well, today I woke up to a frozen boot animation screen, even on ondemand. Although ondemand lasted longer before crashing.
There might be much more issues with CM.
I will test out OmniRom later this afternoon.

Hm. That present some new challenge. I am back to cm now to test it more. will also update the kernel soon to apply some changes in governors and other changes to improve stability.

Best overall kernel for Pixel4/XL

I tested all of the avaliable kernels on 4 XL.
Used ondemand cpu governor,simple_ondemand gpu governor and fiops i/o scheduler with fsync disabled(note that some kernels like franken didnt support governor changing,settings didn't apply on boot for some reason so I done the test with schedutil cpu governor also). Best overall for speed and battery life is elementalx. Works awesome on any ROM. With others I had issues with small lags here and there but with ex kernel NEVER and I mean it.
Also Naptime app AKA agressive doze is total crap as I actually had better standby battery life without it.
Use AOSIP ROM with Ex kernel(block wakelocks also) for best balance between performance and battery life.
Hope this article will help someone.

Same here, that's why i currently use stock. I agree with ex, it's probably the best one after stock one (No micro lags)

No for the ones I'm using(whatsapp,gmail,instagram,twitter....) if you block the wakelocks I sent in screenshot. If you block advanced ones then there can be problems maybe but I didn't test that as standby time and deep sleep are great.

ex kernel works even better with aosip. But you can use it on stock also. I noticed that on aosip I get some extra battery juice and little bit faster performance if that matters to you. Battery life is more important for me.
