working very well sir.
Very excited to see you sir in YU yureka development forum.
Intelliplug working very well.
Thanks for adding new governor and I/O..
:good::good:
Have tested the kernel on dumtara's CM11 build, Very stable with all the features working very well and smooth. Used kernel Aduitor app to tune kernel parameters and to verify things like core plugging features. Daily Driver :good:
By any chance is it possible to enable screen color calibration with the help of kernel?

It is, I would have to look at the drivers for it and see if they are compatible on this device or not. If they are I can get it added.
Confused?

AFAIK its because the governors were built for single core devices during the ICS period. Those governors have poor performance handling over multicore architecture. Correct me if i am wrong.

Quick charging is not based solely on kernel, the battery must be able to accept it, I do not wish to up the amperage going to the battery at this time. It is not exactly safe and we don't know the limits of the device's battery yet, I would hate for you to wake up with your battery exploded.
its good to see development of this kernel going on a great pace.
Your opinion pls
Thank you for the kernel,
@DespairFactor........ Just curious to know what Cpu governor and I/o scheduler combo you would suggest for a user who is not much into gamig but heavy 3g web browsing and music fanboy.
I need good battery life.

From my experience. Ondemand/noop with min/max frequency at 400Mhz/1036Mhz gives good battery backup. Make sure you enable the core plugging option.

Not even sure if the Soc has the feature for this device. Any way to figure that up??, On S3 mini i could check the receiving current Amps to verify using an app.??
615 Soc spec says its available within, But under devices section yureka is not mentioned on the Qualcomm website for QuickCharge. AFAIK i know nexus 6 with bigger battery, charges faster.

On nexus 6 our battery has extra components to allow for the amperage provided by the quick charge chargers. The SoC can have features, but if the OEM doesn't enable them with the components or code required it won't work. We have LED on Nexus 6 for example, but it doesn't blink, this is because it was not coded to work.

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

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:
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.

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

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
DESCRIPTION
So this is a cooked RazR i boot.img that contains a custom compiled Kernel for our device, it was patched to be kept up to date and has some changes to help on battery savings, plus some cpu-freq drivers which which help our device a lot.
InteractiveX2 CPU Governor -- Like Interactive, and fine tweaked to only jump to 1.8 GHz on lighter/faster load increases, comes with a screen-off profile to lock down the frequency and offlinining of the rest of the CPU's defined as non-boot -- being an SMT processor this makes it easier to get the phone to deep sleep even when it wakes up to do something by reducing the complexity of the system.
Conservative CPU Governor -- Similar to ondemand. However, before the governor takes this lower frequency and slower clocked in the upper area, which has positive effects on the battery life.
Ondemand CPU Governor (Re)added -- it was originaly on ICS stock Kernel, it adjusts the CPU frequency to the given requirements, however quickly clocked in the upper frequency range to ensure smooth working.
Performance CPU Governor -- this will clock the CPU frequency to the top, not recommended for prolonged use.
SimpleIO Scheduler (Default) -- is a mixture of Noop & Deadline and one of my favorites.
V(R) IO Scheduler -- is the best scheduler for benchmarks, in everyday use can become unstable.
BFQ IO Scheduler -- A proportional-share storage-I/O scheduler that also supports hierarchical scheduling with a cgroups interface with Low latency and high throughput.
ROW IO Scheduler -- This one is very battery friendly and now my favorite for mobile decies by it's simplicity and responsiveness.
It is known to work on stock & stock based ROM's (such as this one where it is included).
As of other differences there are a lot of GNU compiler flags optimizations, by knowing that the compiler wouldn't know some vital information since it is a remote target different than from where I am compiling so I decided to be pretty explicit.

NOTES
For more information regarding governors, schedulers, modules, etc visit this thread by forum member droidphile.
This is my personal experience to other people on compiler flags, if you guys want to try -O3 straight ahead you will face issues on battery readings unless you remove the -ftree-vectorize flags on the battery modules that get compiled.
[IMPORTANT] For changing the CPU governor please use No-frills CPU Control, Since other apps such as SetCPU and AnTuTu CPU Master both only change CPU0 and may cause conflicts.
INSTRUCTIONS
You MUST be unlocked, and to take full advantage of other modules it is recommend to be rooted.
I will put something more descriptive here, but you can flash it with fastboot by doing: fastboot -i 8888 flash boot <boot.img>.
THANKS TO OTHERS
First of all thanks to Matorola/Intel for putting the main source and for Turl on giving me some info when unpacking/packing the boot images. Also to mattlgroff for the tutorial on unlocking the phone, more thanks to imoseyon and Mike Chan for providing the interactiveX2 source code and changes, it it is now my favorite CPU governor and also to HSD-Pilot for posting this originally on another forum -- I based my formatting from his post.

So is this kernel designed for speed or battery life, or a mixture of both?
Also will this work on the 91.2.26001 JB.EU rom?

By default for a mixture of both. But can be further chose different governors and parameters of the governors for different choices for the user. You can for example choose conservative governor and get more battery life and less performance.
And yes It can be used on that ROM. :good:
It works on jelly bean alright... but with this I'm missing the features of the Arman AIO boot v4 and I just can't live without it...

Yeah, it was internal changes and some screwing around while playing with it. Aiming for more features and once a 'finalized' kernel build is there I will probably do change-logs and change the scheme of numbering.

Tried to fix and make SavagedZen more reponsive, but it is a weird governor, and also included InteractiveX in the meantime (no bug there).
Will probably just put into Github after this change so other people can see the changelogs.

Damn, ok and thanks! ... so InteractiveX is not functional yet sounds like it must have something to do with the early suspend portion -- will eventually fix it. Good thing is that smartassV2 works flawless!
Nice work on the governors!
I remembered some governor benchmarks I read a while ago on this forum, and I thought you might be interested in it:
[REF][GUIDE] Battery Saving Governor Benchmarks
Some interesting quotes from the above thread:
the difference between the best (smartassV2) and worst drain (lazy) is 0.05mA (a tiny amount)
Click to expand...
Click to collapse
choosing SmartassV2 over Lazy would prevent about 600mA being wasted in one hour. To put this in context, that is enough to power your screen for 3 seconds (assuming a drain of 200mA).

Furthermore, I remember another thread (which I have not found), which showed that governors which did not jump straight to the highest frequency could actually negatively impact the battery life. The reason behind it is that CPU usage is only a fraction of the battery drain, and having a slower CPU means applications have to spend longer in active state, thereby also causing other components battery drain over a longer period of time. The display is the biggest battery eater, followed by the radios.
Basically, what I trying to say, is (most) governors have no perceptible impact on battery life, and I believe users who report otherwise suffer from the placebo effect. So I think focusing on a stable default governor which gives a smooth lag free experience is the way to go.

I agree for the most part but that really depends a lot on the type of processor and SoC capabilities, for phones like us I focused on the tweaked smartassV2 further to get it to ramp up and down faster, and it is noticeable smoother. , good battery life since it ramps down better than the on-demand or interactive governors here!
SmartassV2 was the winner on our testing too so we left that one . I just wanted to get InteractiveX working on it for future flexibility and the days that I messed up with SavagedZen it was just an experiment as I had never tried it before -- the results was that I did not like it a lot or I ported it wrong! haha
Friend'm using interactiveX governor since yesterday, andthe results seem to be good and had no lagg dabateria useful life is good (since I am a hard-user).
but honestly the samatassV2 is better, it seems that runs smoother on my device!
but just wanted to note that the InteractiveX is working!
sorry for bad english
First time posting here. And first time user of custom ROMs.
I recently unlocked my Incredible S and flashed VivoKat 4.4 by szezso on it. It is a nice build and most things work in beta quite well; however, I don't have permissions to post on that board to report bugs and ask other build related questions, like how is battery life compared to other ROMs.
I noticed I barely get 1 battery charge per day, whereas I used to get 2 days with my old gingerbread.
So I was wondering if I should go with an older ROM, feature complete, that might have better battery life. If so, which build do you recommend?
Thanks
PS: to the guys on the VivoKat thread (since I can't post there), here are some of the bigger bugs I found:
- microphone doesn't work on speaker mode
- physical buttons don't work if you disable touch-vibration on them
- main screen icons/shortcuts disappear from time to time if the apps crash
Question:
- to install today's update of VivoKat do I need to wipe everything (all data) and flash the new version, or can I update without wiping everything clean?
- I have the full "ROM manager" app, but it doesn't find updates for this build. Will that be available at some point?
(I really like the look of 4.4 on this custom ROM so it's be nice to help out with finding bugs - good work szezso)

That's the actual battery life. With each new android version, you have a lot more processes running in the background. A lot more Google processes too
It should be ok to just flash the update, but if you run into bugs, don't report them as developers don't have a way of telling whether its from issues caused from dirty flash or from the actual ROM itself.
No it will never be available in the ROM manager app. ROM Manager does not search XDA for ROMs and VivoKat is ported by Szeszo personally.
Thanks.
That answers my questions.
And battery life improved after turning off "Location"
You can also log-out from different accounts such as fb, and so one. some of apps are eating battery. For example some email clients...
moreover, you can turn off wifi
you use Vivokat as your daily driver, that one seems still in beta stage

Overclocking uses more battery because of both freq and voltage
Simple equation is this
Power used= freq * voltage^2
So if you lower the voltage to the same as the prev max freq, then you will be using more power still. Just fyi cause I don't think it's ever been brought up around here

according to my test, i just lower the frequency to the normal.

so de-overlock is work for me.

Voltage changes should make a lot of difference too. But not as evident on the vivo as on big quad core snapdragons
The Gpu oc is not really overclock, it's forcing to 245mhz to up performance

i did not explain my kernel.
the kernel that i using is default overclocking.
my work just tweak it to the normal.
before tuning, in idle situation, one day could consume a battery.
after tuning, a battery could use more than one day.
i just want it back to normal.
i do not know that it is really OC, but according to my test.
the frequency is actually higher that it default.
up to 353Mhz, default is 245M.
so i could sure it is overclocking.
this data is collected in it's kernel, the real runtime data.

Ahh, so you've got the stock acpuclock freq table I get it
You have git public so we can understand?

my work just tweak back the GPU, not CPU.
i am still think that i need to tweak the CPU back to normal or not.
because i did not ask the author that i could post or not.
now the code just store in my computer.

kernel code is GPL, if you got it from a publicly available source then no permissions really needed
If you come up with anything that you think may be beneficial.. maybe me or @szezso can work on integrating it or you can post it somewhere

OK, i will.
the most benefit thing to me for now is to create other branch that did not overclock the GPU.
it will help solve the battery consume problem.
And split the kernel version, i need to manually search commit to find the cm 10.2's kernel.

yes, but now the newest master is a beta version branch.
building that kernel will causing error.
you maybe need to post which the commit url that the cm version is using
by the way, i also patch another new feature in my kernel.

OK, I've tried everything, time to ask for help. I've used quite a few kernel tuning apps, including your own, and no matter what i try, my settings won't restore on boot for one, and two, no matter what I set my min/max CPU to it will randomly jump back up to 1728 Min and 2803 Max and change my governor to interatcive. I'll notice my battery draining quicker, that's when I catch it and adjust it down. What am I doing wrong?

Hi twistedumbrella
I have a question.
Is there any benefit whatsoever in flashing any custom
kernels if the user never plans to modify or change any
of the default settings in the custom kernel?
If it's beneficial to flash a custom kernel without changing
any of the kernel's default settings what are the benefits?
Thanks!

The advantage to a custom kernel is the updated code. Even if defaults are left as is, they are not necessarily stock features. Stock kernels are only released with firmware updates, so a lot of the Linux updates can take a long time to arrive. Sometimes the carrier or manufacturer may not even perform Linux or upstream updates, only what it took to match any system changes.
Custom kernels often include additional battery saving or performance updates from the community. These updates may never be officially submitted. These updates may also be too specialized for the "general" kernel most manufacturers maintain, so they are intentionally bypassed.
Configuration is personal preference based on intended use. There is no benefit to using defaults other than lack of desire to customize. The defaults are generally what will be just enough of a starting point for everyone to easily tweak it to their desires, not necessarily what is best.
I configure my defaults based on averages. Some use what they consider the best overall setup for typical usage. Some aim for a specific usage scenario. I have to reconfigure the settings when I install because the defaults don't fit how I use the device (testing games for class projects).
It really is about finding what works for you even by trial and error.
On boot.tmo.11-08-2014_22.12.img
Can't change clock freq values at all. max and min stays at 1.498 GHz at all times.
Same issue is there a way to fix or should I just revert to an older kernel

It's being fixed. It was an issue with the defaults for umbrella_core. Temporary solution is to change governors.
Its stuck for me with every governor...... Just reverted... Anyway this kernel doesn't have BFQ... What's the next best scheduler for HD video recording.. Or are any if the included schedulers based off bfq? I just want to assign it as my SD cards scheduler because that's where I record everything .

CFQ is the closest. I forget if that was already built in. If not, row.
I will second Confirm the stuck govs and clock issue I get 1.4 low and 2.6 high and nothing changes no matter what app I use, also had 2 uncommanded reboot with screen off. Rolled back to previous one.

It's just a lot of busy work. Since it's online, we have to record presentations, record an explanation of all our changes, demonstrate the code in action, talk about plans, etc.
After all that I have to question why I had to submit an outline, repo, and binary. It's not like they're going to read the book when they can watch the movie instead.
Pushing an update now that appears to have resolved the issue. It was not the governors at all. Like any other frequency or screen issue thus far, it was hardlimit
I understand completely. I have an IT degree and been working in IT professionally since 1987. It has served me well so far.
After a lot of digging for where something is setting 1497600 (1.49) because the one place I had has long since been removed, I came across:
Code:
#define MIN_TOUCH_LOW_LIMIT 1497600
in cpufreq.h which is part of the stock kernel code. This is used to make sure that when the screen is being used, the CPU ramps up enough to make sure touch is smooth. That is NOT something I added into the kernel. Hardlimit added the capability to adjust these values, but they are still being set by waking the phone.
Anyway, the point is that I am doing what I can to resolve them getting "stuck" on this value, but the purpose of this post is to say that it may still be a "favored" value, but that is just how Samsung intended it.
custom kernel
WHY does this kernel go makes my cpu only go from 1497 MHz to 2457 MHz???
Even if I change the frequency of the cpu to max 2.8 GHz and min 268 MHz, it stays from 1497 and 2457MHz.

It hates you. It obviously isn't any of the huge discussion in the main development thread or this one if you still had to ask, so that's the only other answer I can come up with.

Ouch. That is like "can anyone verify this developer is worthless?"
Anyway, there is an untested update being pushed. The untested part should fix the frequency issue. It's untested because the change is swapping two lines. High was getting written to low and low to high. The result was everything reading invalid and defaulting to mid.
Hi everyone,
This is my kernel based on Sultan's sources upstreamed merged with LA.BF.1.1.3-02310-8x26.0. I have put tons of work into this over the last few months, and before I get started I would just like to thank those who have helped me get a better grasp on programming over the last year or so:
Mathew Alex (DespairFactor), Chad Russel, Rohit Poroli, dingermtb, Adesh15, Lord Boeffla, ZaneZam, NoSpamDan, Nachiket Namjoshi, Martinusbe, Joshwin Aranha, SHM, Sultan, DerRomtester, Franco, AK, myfluxi, GalaticStryder, Gandalf, and maxwenn!
Were it not for these people, you would not have this kernel.
I want to go with the KISS philosiphy on this one and make the redundant claim that if you want a proper changelog, use GitHub. I do a lot for every release so maintaining it all in the thread without a bunch of clutter and wasted time is pointless. If I think it's cool or notable, I will bring it up.
I always compile this with the latest version of Uber, it has Sultans thermal driver, it uses Blu Plug as the default hot plug, and I left CPU input boost in tact (not CPU boost) from Sultan's kernel. There are several other features of this kernel that I will not go over quite frankly because it would take forever. Just believe me when I say I put a lot of effort into it
As usual, disrespect will not be tolerated. Failure to exemplify respect will get you reported to a mod. Case closed. Be excellent to one another.

I am not responsible for any issues you may have. Those are all on you.

Your flash, your choice.

Update coming at you later today after I do a bit more testing
What's planned:
1. Blu Plug (disabled)
2. Improved NEON implementation
3. BFQ instead of Zen as the default IO schedular. I prefer it's greater precision over the deduced latency... On top of that external write speeds seem rk be faster which is a huge bonus for me. Heavy workloads should benefit as well
4. I updated my thermal driver with Franco's latest patches and an additional throttling step. Throttling will also kick in at 42c instead of 40c for those of you living in areas with higher ambient temperatures
5. 2.5ghz was enabled by default for PVS8 users with the optimal voltage. I have spent hours testing it and thus far haven't encountered any issues
6. Faster vmstat
7. Improvements made to CPU boost
8. Improvements to sound control
9. More hidden kernel addresses
10. Several other performance improvements and bugs fixed

I'm quite happy with this release and it truly is a milestone from where deCAF first started. Hosts of improvements have been made and the kernel has been shaping up nicely with my no unneeded BS policy this time around.
Merry Christmas everyone! I hope the best for all of you
