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
according to my search, i have see many kernel of the ROM is overclock feature.
but the overclock is power consumption.
for now i have using the cyanvivo,
i de-overclock his GPU and it seems become normal.

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.
and it actually consume less power.
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
Sent from my HTC One using XDA Premium 4 mobile app
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.

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.

Big thanks to my friend who upgraded his phone and gave me his Atrix. BIG THANKS to my wife for giving me a quad-core CPU to upgrade our desktop (after I replaced the starter and alternator of her car) and also allowing me some time off from the kids to give me some time to build this combo. Big thanks to Blades, pershoot, koush, faux123, cyanogen, the whole Atrix-dev team and the Cyanomodgen Team, and other devs whom I might have missed , to all users of Gtabs, Transformer and Atrix for testing out my work and giving back their precious input.
WARNING: ONLY FOR ELITE TEGRAS!!!
To find out if you have an elite tegra, please flash my Elite kernel on this link
http://forum.xda-developers.com/showthread.php?t=1354502
and see if you can boot your atrix and it works. If my kernel don't boot, then this combo is not for you.
Updated: 1/30/2012
1. Added some OpenGL changes in the ROM
2. Added memory tweaks in the kernel
Here is the link
http://www.tunerspotter.com/clemsyn/ClemsynCyanogenEGLCombo1.5.zip
BTW, Please
here and help me buy some diapers
---------------------------------------------
---------------------------------------------
UPDATE: 1/28/2012
Changes:
1. Played with some voltages making changes within Nvidia requirements
2. Increased overclock to 1.5 ghz (YAY!!! It's going to be pretty hot in there)
3. Increased audio bitrate for HD 1080p (since the older one had a lower bitrate)
LINK
http://www.tunerspotter.com/clemsyn/Clemsyn1.5cyanoElite.zip
BTW, I would like your opinion in HD 1080p recording. Thanks.
----------------------------------------------------------
----------------------------------------------------------
Changes:
1. ROM changes made to optimize overclock settings. This ROM will have a maximum speed of 1.4 ghz without the use of overclocking apps. If you wish to undervolt, then you can use PimpCPU, SetCPU, CPUMaster, System Tuner and etc....
2. Modifited bitrate and FPS for 1080p video recording for better result (IMHO but your input on this will be greatly appreciated)
3. The rest is regular Cyanogen gingerbread with fingerprint mods by the dev team
Your input will be appreciated

Glad to see you here. I am one of the few who had boot problems with your other kernel.... but I'm still gonna try flashing this one.
I keep a backup of my current kernel on my ext-sdcard, so I'm not worried.
Do you know what what causing the issues with some phones not booting on your kernels? I can't remember what the problem was. Is it possible to fix?

It's the same kernel so it will not boot Didn't have time to play with the kernel because I was excited in compiling cyanogen mod in my new quad core which compiled in 23 minutes (last time I tried it on my laptop which was a core duo, it took me 7 hours).
It could be a couple of reasons.
1. GPU, AVP etc where overclocked
2. Memory timings where pretty aggresive
Exact same kernel? No changes to it? (Like patching to .53 from .48)

This is a combo. Rom and Kernel. LOL.
Here we go - What I believe is the first custom kernel built from source for GT-N7000 ICS.
READ THIS POST INCLUDING KNOWN ISSUES BEFORE POSTING!
Driving Always For User Quality - DAFUQ!!!!
This is built by applying some small fixes to the GT-I9100 update4 source base so that the stylus and charger drivers build properly.
Source code is at: https://github.com/Entropy512/kernel_galaxys2_ics/commits/entropy_kernel_main
Initramfs git is at: https://github.com/Entropy512/initramfs_galaxynote_ics/commits/master
It has been tested so far with Criskelo's XXLPY-based release, but should work with most other Touchwiz-based N7000 ICS releases. AOSP firmwares are not supported by this kernel. They may boot and sort-of run, but no bug reports will be accepted if you're running an AOSP-based firmware. No bootloader flashing is required.
Features:
See my I777 ICS kernel thread for now - it's built off of the same source base (but N7000 users should post here)
The one specific feature I should advertise here - This is built from I9100 Update4 sources. This appears to be the only source base so far for Samsung Exynos4 kernels that doesn't carry a high risk of permanent damage to your eMMC chip. (e.g. it should be safe from all of the nightmares people have encountered with ICS leaks here, however I cannot make any guarantees.)
Known issues:
Some of you are used to kernels that autoroot a ROM for you - this one will not and never will especially now that two different Superuser packages exist. Flash SuperSU or Superuser in CWM, pick your poison.
Camera preview is black
Hardware accelerated video display is not working
Because of these known issues, the primary use for this kernel is to reset the flash counter with TriangleAway (which DOES work on this kernel)
Change Log
5/27/2012:
Pulled in some changes from the N7000 source release. Wifi and speakerphone are now working with XXLPY, however - hwaccel video is still broken.
Fixing hwaccel video requires major work or just trashing everything and starting from the N7000 source release and readding features there.
5/2/2012:
Charging now works normally. It turns out some devices have an SMB136 charger, others have an SMB328 - Now both are enabled.
4/26/2012:
Call audio fixed (Note only)
Bumped first GPU step default up to 100 MHz from 66 (Note only)
Increased conservative governor freq step from 5% to 10%
4/24/2012:
Initial release
FAQ
Q: What's up with the name?
A: Since I run CM9, this can no longer be considered my "daily driver" - so the Daily Driver name no longer really applies. I haven't picked a good name yet, expect this to change with my mood. Names may get more sensible as the mental damage caused by watching the ZOMBIE ASS trailer heals.

See the I777 thread and the git commits for what's in there.
It is in general battery-optimized - Mali 3-step defaults are battery-oriented, default governor is a tuned conservative, reduce the polling interval of it for better results.
As this is built off of I9100 sources, there might be some Note-specific things missing. I never did Gingerbread kernel development on the Note. One thing is - this should not burn out your eMMC like many of the leaks can.

I'm working with codeworkx and xplodwild on getting that going. I need to clean up extract-files.sh and the vendor/prop repo, among a few other things. I won't have time to work it the next few days though.
If you want to improve performance, try bumping up the GPU frequency for the lowest step and reduce its staycount to 0. For battery-saving purposes, the first GPU step is a bit on the low side. I might bump it up a little, there's a BIG jump between 66 and 100 MHz.
Instead of being 166/266 MHz, it's 66/166/266 MHz. Should improve screen-on battery life.

ok, so for ~5 seconds after you unlock the phone there is a noticeable stutter during transitions, even using ondemand.
scrolling is very smooth tho, even in plume...
Try increasing the frequency for the lowest GPU step, or reduce its staycount to 0.
Another option, try conservative but change freq_step to 15. I'm probably going to change that as the default.
Where can I find a nightly build to get initial extract-files ?

seems the same using conservative with freq_step at 15. the first time you open the app drawer it stutters but the 2nd and 3rd times it get smoother til it doesnt stutter any more. turn the screen off and back on and its the same again.

New thread to house the custom kernel built with linaro's gcc 4.7.1 toolchain
This *should* work with any AOSP ics rom.
Just because this kernel is built with the linaro toolchain it does not mean the rom needs to be compiled in a certain way.
Download here: http://tinyw.in/gnOy
I'll add more details when i have some more time.

Good question. This *should* work with any ics rom.
I tested this out last night (been running mamarley's kernel) and I ended up switching back for two reasons: first, this doesn't appear to have the 128MHz CPU speed - I'm not sure if that's intentional or not. And secondly, my phone apparently couldn't handle this kernel on 1113MHz - I got lots of FCs. And the rating on Nenamark was essentially the same as my baseline on other kernels.
Just some observations - and your mileage may vary! I really appreciate the fact that this is even being worked on, invisiblek.
EDIT: Totally meant AnTuTu, not Nenamark.

Great to hear feedback. Thats all im looking for here really.. It doesnt have 128mhz because its the same voltage as 245 hence no real benefit to having it. Plus some devices are unstable there. I never overclock but i can look at the voltages and maybe get 1113 stable
I can say it works on the new ICS TW rom, drains kinda fast although I think its rom related only.
I had only one reboot, got a freeze and then 10 seconds later a reboot. Its the only one I've had since reapplying new settings.
On freeze I was running SAv2 1113 Max/245 Min.
I have now lowered it to 998 and its running fine on that rom.
Other than that, its amazing.

i take this back, 128mhz is 25mV under 245mhz here

Can you clear up the linaro tool chain for me, I'm confused as to if the ROM currently utilizes it... and if so is there a certain kernel you have to use along side it. Sorry if that's a stupid question...

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 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.

This is the support thread for the T-Mobile / U.S. Cellular variant of the StarKissed Note 4 kernel.
This kernel currently supports all North American carriers through the use of specialized release packages that will detect your device version and make appropriate adjustments.
Kernel Development Thread:
http://forum.xda-developers.com/showthread.php?t=2915824
Direct installation available via Flashify (for root users) - Android Apps on Google Play
Heimdall with the S5 patch is needed to flash from a computer. Odin cannot flash this 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!
Click to expand...
Click to collapse
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.
