[KERNEL][ICS]JARVIS-v8 for LGP990

JARVIS Kernel for LGP990
Only for CM/Miui or AOSP roms​
Deceided that XDA needs a thread too. I won't look through it really often. I hope that other more experienced members can answer some easy questions, so I can focus on developing things.
Features:
3.0.y Kernel
Interfaces to control a bunch of Features (Like vibration strength)
Overall optimized parameters to provide a smooth user experience
working UMS - thanks Harsh
App which controls all the interfaces
Disclaimer:
I'm not responsible if your phone is fried by the kernel or you miss some important phone call! I'm not forcing you to install this Kernel and so it isn't my fault.
Download:

Or Update via my app:
​
Don't use profiles, because they can lead to instabilities.. and they're unnecessary.
Stay away from SetCPU or any other app. Could lead to problems because of the customizable OC. Wait for my app until it's not ready use command line coupled with a init.d script.
You don't need to optimize any values in the ram disk. It should work perfectly without any other tweaks.
When you experience problems like random reboots, SODS, etc. try to go back to stock settings. And apply my 1 GHz frequency table. If this isn't fixing your problems report a bug with detailed informations. Like ROM, Settings, etc.
If a person reported a bug and you experienced it too, +1 this bug report or whatever. In this case I know that the bug isn't only happening on one specific device.

I'm damn lazy. So just use my github commit history (here).

Thanks to:
Dekudan/Victor Von Zeppelin - for creating awesome icons for the app
Arcee - Setting up CyanogenMod and everything.. Just awesome
wkpark - for his cherry-pick marathon.. This guy really has endurance hehe
Ezekeel - Really innovative dev with impressive ideas.
Everyone who open sourced their work

Interfaces:​
CPU Control:
/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
Used to set the minimum frequency.
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Used to set the maximum frequency.
​
Fsync Control:
/sys/class/misc/fsynccontrol/fsync_enabled (Read and Write)
Enable/disable single file/filessystem sync.
WARNING: This could lead to potential data loss after a unwanted reboot (battery pull)
enable=1, disable=0 (default enabled)​
Vibrator Control:
/sys/class/misc/vibratorcontrol/vibrator_strength
Set the vibration strength.
possible values: 1500-3600​
Force Fast Charge:
/sys/kernel/fast_charge/force_charge_mode
changes the usb charging mode. We have 3 modes:
Fast - Forces fast AC charging. Disable data transfer!
Slow - Always charges slow (like on a normal PC USB bus)
Auto - automatical detects which mode should be set.
Possible values: fast=1, slow=2, auto=0​
Example
Use adb to connect to your device and then in adb shell (with su) (you can setup a init.d script to auto apply everything)
We want more vibration because we can hardly notice it and want to pwn our friend with benchmarks. Additionally we want to charge our device faster.
Code:
echo 3500 > /sys/class/misc/vibratorcontrol/vibrator_strength
echo 1 > /sys/kernel/fast_charge/force_charge_mode
echo 0 > /sys/class/misc/fsynccontrol/fsync_enabled
And that's it

damn, it really is fast, never seen any kernel score so high when it comes to cpu, just need a lil I\O tweaking and its perfect. i think

I think CPU and Mem is more important than I/O, but not so easy to do.

that is the way sysfs works
you will need to make a init.d script for it so it will set the values at boot time
or just wait for the app

i had to change some things in my rom to support UMS on 3.0.y kernel (since it differs really alot from 2.36.x kernel) i think that is the cause

Stable ROM with best battery life

After so much experimentation and flashing, I think it's finally time to settle down on a single good ROM for a while. Can someone recommend a good stable rom (2.3 or above) which has a great battery life? My data(2G) remains on all the time and I need good battery life to make it through the day.
This is my only requirement, any suggestions???

Gdx v19 or 20.those have nice battery and performance life
Sent from my X8 using xda premium

I recommend you reading in General Section theres a lot of topics and review regarding ROMs

GingerDX, PrimeHD. Did you unlock your Bootloader?

I can get 3 days of good usage using FroyoPro2.5 with alfsv9a-GDX..
No lags ever!

GCR,GZR,GDX v22, iXperia,...

GDX v28b :good:

GCR (GingerCruzt) 8.4 !:good:

Official 2.1 Eclair it's battery life

Really? How much days?

yes about 1-2 days. but
depending on usage including
my love online at hp. thus
causing the battery rapidly
diminishing.

So GCR is better (6days)!

Seems alot to me 6 days.. Which version of GC? This post you say 8.4, your last post in the GC thread says 8.5
Changelog for 8.4 states:
Revision 8.4
-changed boot animation
- almost same ui, framework but added transitions
- fixed the ringlock controls with the radio issue
- A lot of widgets
Bugs:
- xLoud bug...
-battery goes out quite rapidely(?? confirm anyone?)
- AutoBrightness has some flickering(?)

And it only works with nAa8
Do you ever use data, wifi, gps, music, videos or any of the features of the phone at all?
It's obvious that you don't overclock but do you undervolt?
I'd just love to know how on earth you manage to get 6 days + out of our phones.
Cheers.

I use version 8.4! It's just for stock kernel. No I didn't overclock and I didn't undervolt.
No I didn't use data,gps,videos. I just play music,browse on wifi. And I use 2G all time! I delete unused running services!
On some rom,I don't use music,videos,wifi,gps... 2g all time... but I get just 2/3 days!

Nice did t see that. Seems to make my phone faster will have to keep running it and see
Sent from my HTC Vivid 4G

although it did seem smoother, definitely seemed to punish my battery (cpu was not spending as much time in deep sleep). Really cant say whether it was a placebo, or simply the CPU being faster to respond due to not sleeping. ymmv

This works heaps better than Seeder:

Was using this on the sensation before getting the Vivid... going to try it now to see if it works as i'm not sure if it was kernel support dependent.. either way.. waiting to see if the creator of the Sultan Kernel for the sensation can port the kernel for the Vivid so we can also get FRANDOM support (read point 5 of above thread for info):

Improvement is very noticeable and i actually get better battery life than with Seeder.... but improvement will be far more significant once we get a kernel with Frandom support and fingers crossed the dev pulls through.
It's not a raw or outright performance improvement..it removes lag so much that it feels like a computer that you just doubled the ram on as things load a lot quicker.
There was sort of an issue before that wasn't really an issue which was a too aggressive ad-blocker as some people preferred to have ads while playing games for free platinum/gold/etc offer ads...
It's not detrimental though.. just flash the uninstall zip if you don't like it.. i'm currently running it with the official CM10.

What's the best ROM for better battery performance?

Hello guys, over the past month I have been trying to find the best ROM for the best battery performance, I am thinking that the ones made based on lineage are the best, however I don't find it yet, perhaps you have already found it. Please share your opinions.

Stock is the best I think.
If still not satisfied couple it with some custom kernel and tweak your settings.

Sounds very promising, I will give it a try! thank you, I read that android 6 is more battery friendly, compared to 7.0; But I wonder what did you have to do in order to instal it? I dont think that if I am running 7.1 I can use right away, I am thinking I would need to downgrade first right?

Stock + franco kernel here works like a charm.

Stock is a good option for battery no doubt, why not have plenty of additional features without compromising on battery life! CM theme engine or Substratum theme engine lets us set black themes which will also increase our battery life and enhance looks too. I'm on cm13 for a long time and haven't found any bugs yet.

SyCreed said:
where is the problem to use substraatum on stock rom?
Just get root and you're good to go.
(dont forget to apply black theme in settings)
Swift black \ dark works for me like a chram, no issues at all !
Good luck

May be i didn't know stock has OMS support which will turn everything theme able. I usually end up applying dark themes and getting my notifications background in black with black texts in stock android, in case of custom rom with OMS support or CMTE will resolve these issues.

I'm bone stock, rooted, franco kernel with power save mode enabled (kernel not Android) and naptime app set to aggressive doze. had 3h30m SOT the other day with 47% battery left. Phone off charge at 7am, checked at 8pm with the aforementioned stats.
ROMs very, very, very, very rarely have battery saving properties. Kernel is where it's at.

So is the Stock ROM the most efficient battery ROM at the moment? Or did anyone found another combination that's even better? I'm getting my 1+ soon and want good battery life not like my old honor 8...

What's the SOT you're getting with this combo?

It's not as much the ROM as it is the apps your running, apps like WhatsApp, Facebook, Facebook Messenger and the likes are the real reason for high battery usage in any ROM.
And as always, Google services sometimes goes loco on you eating battery, causing long charging times and heating up the phone. ?

i have tested some roms & kernels ...
as is experienced my self :
- oos + franco kernel is great for normal usage.it isn't good if you play games.phone get hot and battery drop fast + idle drain=0 ( i tried r17 - i don't know if it is better in r23 update )
- cm13 sultanxda : amazing battery life for using normal + for gaming ! but idle drain is a little.not 0
- oos 3.5.4 + dorimax kernel : good battery for normal use + idle drain=0 but gaming no.
- oos + elemental x kernel = wasn't good in battery for my usage
i want to test oos + blue-spark kernel : seems to be good.but not sure..
& sultanxda linage 14.1 is good i think.i wait for later updates...
i haven't tried any other custom roms.there are so many roms and no time to test them all !
i hope my post helps.

@AnDrOiiiD_YT i came from a different profile which is fairpark with SOT for about 13hrs but then i switched to project zhana for balanced performance + battery with SOT 9hrs

Leeco le 2 Benchmarks and performance

I know that our 2016 le 2 is not going to break any land speed records but I'm just curious about what figures it can post. I am a fan of benchmark scores and before you crucify me, yeah! I know benchmarks don't show real world performance. But would it hurt to run them? FOR SCIENCE??
Anyway, let's get away from the politics a bit and share the best benchmark scores we've managed on our lowly le 2. It doesn't matter if it is the famous Antutu, Geekbench, 3DMark, benchmark pi, a1 SD bench, or whatever you had a go at. Just share it here for the world to see.
Sharing Format
Please attach a screenshot of whichever benchmark you ran and the score you got. Also tell us which ROM you were using, if you had installed any custom kernel, overclocks, and any other tweaks that could have led you to that marvelous score.
Example:
I recently did a 3DMark test on my le 2 (find the screenshot(s)) attached. My phone is running SmallEUI version 3, illusion kernel v. 2.5, and I had all cores locked on performance. I also had a fan blowing at my phone for a cooling breeze.

My phone is less than 2 months old. I must have done something wrong to get such a low score. Your 3D bench looks like mine when I was running smallEUI. I'm installing Arrow OS Pie today. Someone recommended it to me so I am going to try it today.
Edit: again reposted your photos from imgur.

Mine is week and half. I really want to flash bunch of roms, but this one just works too good so I can't justify it. Have fun and good luck. Btw I noticed in other threads other people having ~70k score, so it's not just you.

Yesterday I tried Arrow OS pie and Lineage 16. They had same problems as most other pie ROMS so I removed them both. My phone is a x526, the 3/64 GB version. On Arrow OS with overload kernel, I got 110k Antutu. Lineage got 105k with stock kernel. But performance is nothing without stability. Especially the camera because my phone is a daily driver. How's your camera working?

Yes, overclocking works but just a little bit. Stability goes out the window as soon as you start overclocking the SD652. Since it's a 28nm fab chip, it can't go much faster without catastrophic failure.
I read that according to Qualcomm it can do a maximum of 2.2 ghz at 16nm fab process. That's just 400 mhz faster than the current max speed.

How did you get such a high memory speed? Is the phone stable at that performance level?

After many and many test ... this is my result:
Havoc 2.8 (pie)+ some tweak to thermal engine = 119k-120k on antutu score
Havoc 2.8 (pie) + illuminate kernel + some tweak with smartpack kernel manager + some tweak to thermal engine = 120k-121k on antutu score
If u want more info: ask here and i share screenshot of antutu score and my configurartion and mod to obtain this score.
