Here is your answer for wifi:
CHANGE
ro.securestorage.support=true
TO
ro.securestorage.support=false
In your build.prop
To get you BIN, reboot, get a dmesg and search for "ASV-GROUP=". The first set you hit in the log will be your BIN for BIG CPU, the second set with be LITTLE CPU.

Thank you man, can't wait to see ur kernel fully operational as i'the s5

Hell yeah!! Was rocking this great kernel on my old GS4. Glad to see the Edge getting some dev support now, was starting to think I had made a mistake getting it over the regular S6! I don't want a phone I can't tinker with.

I'm attaching my logs there's a lot of ASV http://1drv.ms/1ORUUld

Not sure if we got a language barrier or not here so Ill try to explain again:
Open the dmesg file
Search for "ASV-GROUP="
the first set of 24 or so is your BIG CPU
the second set of 19 or so is your LITTLE CPU (there will be a gap of other types of log info in between the BIG CPU logs and the LITTLE logs entries)

Hehe no language barrier just got confused with the ASV as it shows 0 then 8 that's why I attached if you can have a look. If you don't have time no worries
90% sure it's 8 for both

That is the entry types yes, you do have to pull it as soon as you boot or things get over-written. Here is an example of one of my testers logs:
http://pastebin.com/4gGK46ZS
In lines 245-314 you can see the BIG CPU (his is a 5)
In lines 343-397 you can see the LITTLE CPU (his is a 9)

Yep that's what I got, it's 8 on both, is there a table of the max UV values we can apply depending on the bins? The one on Anand shows few freqs and asvs

There is no guidline for OCing, its trial and error, here is a link to the code with the table in it:
https://github.com/ktoonsez/KTSGS6/...m64/mach-exynos/include/mach/asv-exynos7420.h
Line 1307 is where it starts for the big, 1339 for the little. The ASV8 column is yours since you said your an 8, and you can see the other columns ASV0 thru ASV15

Battery JVK Android OS

Hi,
I have detected the reason why the battery at JVK is always so quickly. The Android OS syndrome.
It is the CPU running at 1000Mhz permanently. Even if the phone is in standby. Otherwise, switch the MHz number in stand down even more. What can you do?

Cpu doesnt always be on 1ghz.You can see in what frequency the phone is using setcpu.

The CPU is not running at 1000MHz constantly. And if you are afraid that it is, do the following:
1. Download SetCPU from the Market.
2. Enable profiles, and set following profiles:
- Charging: min 1000, max 1000;
- Screen Off: min 100, max 200;
- Normal: min 100, max 1000.
This will also increase your battery life!

Concept noob idea for a governor

Hello all !
I was bored in school today so I've written a governor concept idea for quad cores. I'm not a dev AT ALL (for now at least, i'm studying many different stuff, hardware / code related too).
I have no idea if this is possible or if this is clever but I wanted to share it anway. If it gives idea to a developer, that's totally worth it, otherwise, well... I had fun doing it
It's called Progressive.
Progressive
The name of the governor says all. The idea behind it is to be «*progressive*». It means it doesn't unleash the full power when it's not needed. It goes progressively higher in freq with more cores. This should make the phone cooler and the battery better. The delay (3 sec ) is just a number, not sure this is really nice. Also, I'm not sure how the S4 handles temperature.
Max freq 1.5 Ghz
Min freq 384 Mhz
Screen off
=> 384-918 Mhz // not too low frequency to avoid reboot
Screen on without touching since 3 sec // always check after 3 seconds for changing the state
=> 384-1134 Mhz only one core online
Screen on touched
=> 594-1134 Mhz two cores online // bump the min_freq to avoid keyboard lag and to add a bit of butter
Screen on touched with a medium load of task // not sure how quantify this
=> 594 Mhz – 1.5Ghz two cores online
Screen on touched with a high load of task // i.e. Games
=> 702 Mhz – 1.5 Mhz four cores online // max power
We also need a thermal protection to avoid any damage, this should do the trick
If the temp is >= 80°C
=> Two cores online max_freq 1134 Mhz until it reaches 70 °C // not sure about the temp, this can be adjusted
If the temps is >=70°C
=> Let 4 cores being possibly online but lower the max_freq to 1134 Mhz

What do you guys think ? Is this even possible ? Good, bad idea ?
I hope you enjoy reading it as much as I enjoyed to writte it

doesn't it do this already?

I'm not sure how the ondemand governor on nexus 4 works. So I can't really answer, it's really a noob idea that poped into my head today

you pretty much described interactive with mpdecision enabled.
not exactly, but quite.
3 seconds is way too long for the CPU to ramp up (just a matter of tweaking, though). you'd get more lag than you save battery.
mpdecision ramps the cpu to its maximum frequency as soon as a touch input is detected (normally only 2 cores until a certain threshold is reached), so yours should save a bit of power during smaller workloads.
also, if the touch input is released, it clocks the active cores down to 1.02 GHz for a bit before disabling them when not needed.
after all, it seems like a more conservative interactive governor with active mpdecision. could be nice for saving battery while retaining good performance.
it could be a viable choice for those who go for battery life over performance. :good:

Thank you Sir, I understand better how mpdecision works now
Glad to see i'm not completely stupid lol

[Q] CPU activity Core 0

Hi guys,
I have noticed on my one that the first CPU core always sits active about 1/3 usage in idle.
If I touch the screen the 4th core becomes active but not 2 or 3.
If this was a single core phone the phone would go flat quickly with constant CPU use, is it an issue with the one and it's 4 cores?
I do not know what is using the CPU time but I would like to get it to use as least amount of CPU where possible, phone never lasts a day.
This is measured in System Panel and Usemon.
I'm on 1.29.980.2 and not rooted.
Cheers

102 views and no comments or suggestions?
No one checked their own Phone to see if it is normal for one core to be very active all the time?
I don't have a second or third One to check if it is normal behaviour.
If I am doing nothing, not running any app or the such the CPU should be minimal CPU use, just idle time..
Thanks

it is absolutely normal that one core is always active with around 30% of usage. if you start to scroll, the device needs a second core, the 4th one, but these two cores have enough power if you're only scrolling. there is no need for the cores 2 & 3, so they are "inactive" to save battery life.
this is absolutely normal

What you can expect to get benchmark wise with a good CPU OC'd:

Change Log 05.18.2015
1. Add some more protection on hotplugging for phones that are not fully shutting down screen and still register touch while screen is off, causing reboots.
2. Making unified version now, so pay attention that the file name is now changed. There is still seperate version for the S6 and S6 Edge, and also Sprint needs a special due to radical differences from the GSM versions.
3. KTweaker: Added new 3 options prompt when restoring a profile. Instead of a yes/no question to apply, it now gives you the 3 options of: "Apply restored profile with its voltage", "Apply restored profile with my voltage", "Do not apply it"
Change Log 05.12.2015
1. The wait is over for ktoonservative governor!!!!!!!!!!!!!!!!!!!!!!!!
2. ktoonservative governor supports hotplugging for some amazing battery life and still smoooooooooth.
3. Shorten internal kernel name so Antutu wont crash on some phones.
4. LED Fade mode code added.
5. LED fade mode fade up time to set how long it takes to fade in.
6. LED fade mode fade down time to set how long it takes to fade out.
7. Disable LED start hour to allow a start time of when LED are NOT active.
8. Disable LED stop hour to allow a stop time of when LED are NOT active.
9. Disable LED always option to disable LEDs all together.
10. Built with Linaro official 4.9 with -O3 optimizations
11. Added ktoonsified v1 profile made by myself and Luigibull, you can get it in the KTweaker shop in KTweaker app. BE SURE TO LOAD YOU STOCK VOLTAGE TABLE AFTER APPLYING!!!!!!!
Change Log 05.02.2015
1. Added UC and OC steps for both CPU's. Little now ranges from 200-1600 and big ranges from 200-2496. Be sure to adjust voltages accordingly, the UC and OC steps may not work properly for your binned CPU without tweaking the voltage!!!!!!!!!!!!!!!!!
2. Included patch to insure deep sleep is NOT lossed
2. KTweaker 9.3
3. Cleaned up some FC issues
4. GPU screen is now fully functional for all items
5. "Get Phone Information" screen was pretty'd up and added CPU "Time in State" gride for both little and big cpus including Deep Sleep and Total up Time items.
6. OTA is now functional.
7. KTweaker Shop for Profiles is now functional. Only 1 profiles which is the stock settings.
8. Change Log item in KTweaker is now functional.
Change Log 04.29.2015
1. Add voltage control for little and BIG CPU's. Thanks to AndreiLux for pointing me to the right files.
2. Added ondemand and conservative governor.
3. Added CPU Min/Max control for BIG CPU
4. Added ability to tweak governor adjustments.
5. GPU governor selection is working, dont mess with Min/Max yet.
Change Log 04.19.2015
1. First build, things are just getting started
2. Min/Max will look weird upon open KTweaker the first time, just slide the Min and Max bars to what you want, this is only setup for the SMALL CPU.
3. So far you can only control the SMALL CPU which is the cpu that ranges from 400-1500Mhz
4. Control over Scheduler.
5. Control over governor for SMALL CPU.
6. Kernel is setup for SELInux Permissive
7. Lots of dmesg spam removed.
8. Dont bother setting other items in KTweaker just yet since things are just getting started.
9. As with all custom kernels since the S4, you may need to find "securestorage" line in build.prop and change from true to a false if you have trouble with wifi remembering your password after reboots.
10. If you have trouble with S-Health after installing custom kernels, Force Stop it and clear cache/data for the app, that will usually take care of it.
11. Please post a "dmesg" after running the kernel for 10-15 minutes and you have let the phone go into deep sleep at least once so I can remove more dmesg spam.
12. ENJOY the awesome!!!!!!!!!!!!!!!

Here you go man. This is just a test of mostly stock kernel, we are testing for Cell service, Wifi and deep sleep since that seems to be a common problem for anything custom on this device, so make sure you are getting deep sleep first before flashing:
Also, I really need that post your snuck on, lol. U know how to let me take that post over?

haha crap, i didnt realize you had just posted. i think a mod can switch it over to you, or just delete it.

Awesome. Use my app called KTweaker and open it up. Its a slide menu app like Play Store so slide from far left to the right to open the menu and click on "Utilities" then "Generate a dmesg" and post the file for me so I can kill all the dmesg spam and speed this beeach up

thanks man, glad to see you here i remember using your kernel during my s4 days
flashed it and its working great! just one thing. KTweaker is crashing upon starting the app

Thanks man. Do you have root? Do you know how to get dmesg's and logcat's from your PC so I know whats crashing it if there is root installed already?

It crashes for me as well, flashed it with the XtreStroLite ROM.
Edit: Just noticed this page.
Yes, I do have root.
No, I don't know. Mind telling me how? I do have Windows and Ubuntu.
Edit2: No longer crashes after flashing the latest kernel.
Thanks!

Try redownloading, just updated source to OCV and changed a few flags, not sure if it will KTweaker, probably not but worth a shot.

wow, awesum to see you over here, man!
I'd be glad to test, but I have the s6Edge, not the S6, and the phones are just a bit different, and I've already bricked my phone once this week!

I'll be glad to test this for you on the stock ROM with no mods and Deep Sleep *working*. I've searched everywhere for the stock kernel to revert back to in case of issues... No luck, any tips where to find it besides Samsung Opensource?
Edit nevermind, I'll make a backup, duh...

So I just flashed the file from the OP
"KT-SGS6-LP5.0-TW-G920T-04.17.2015.zip"
And it seems like it didn't actually flash. The kernel under info is still 3.10.61-4351281 built on March 27th.
Anybody else seeing this too? Looked in the ZIP and there's a boot.img, along with two modules. The update script looks right. Any ideas?
EDIT: redownloaded, this time the file is a different one, larger 13.5MB vs 11.9MB - this file includes KT Monitor and Tweaker. However, the kernel version is still the same as the old file (with a build date of 3/27)

Yep, I flashed the same OP link and check under about phone, same thing as stated above but the ktweaker app is installed sooo?? Assuming this is expected, I don't see any change in voice calling, wifi, lag etc.. Feels exactly the same so thats good.
Now, everytime I try to open Ktweaker it closes,cleared cache/data etc but no luck..??

Battery drain on CM13 based ROMs

A finding and a question:
1. ksmd is consuming CPU cycles. If I disable ksmd, the loadavg drops dramatically.
Code:
echo 0 > /sys/kernel/mm/ksm/run
It helps reduce battery usage.
2. I am seeing Gmail is consuming a whole lot of CPU cycles and its triggering a media scan. Is anyone else seeing this?
Code:
User 7%, System 36%, IOW 0%, IRQ 0%
User 5 + Nice 11 + Sys 76 + Idle 119 + IOW 0 + IRQ 0 + SIRQ 0 = 211
PID PR CPU% S #THR VSS RSS PCY UID Name
887 1 31% S 4 8564K 2952K fg media_rw /system/bin/sdcard
30426 0 21% S 71 1251556K 132212K bg u0_a123 com.google.android.gm
6735 0 4% R 1 2968K 1180K fg root top
Obviously, killing the process does not help because its system service and will pop right back up.

Cool.. that's good to know. Thanks for the info! Would you say disabling that kernel process reduces battery usage a great deal?
One thing that I have noticed with CM 13/marshmallow builds in general, is that sometimes my device just *will not* connect to the mobile network; sometimes I will get lucky and it will connect just fine, but other times it cannot make a connection to save its soul. When it cannot connect, it persistently tries to connect, over and over again-- even if I'm on Wi-Fi-- and the battery is drained at a very rapid rate. However, when it does connect to the LTE network with no issues, battery drainage becomes a non-issue.
(I'm on Verizon, btw)

I turned the KSM off in the Kernel Auditor and the loadav dropped significantly. It should be removed because it serves no purpose really and changing it every boot is a pain As for the gmail service, I just limited it's wakelocks because it was too damn frequent. But what I am wondering is, how is your loadavg 0.8? mine is 2.28 1.93 2.12 4/1437 4960 ... I think I have a major problem somwhere The lowest it has ever been is 1.60

The loadavg depends on the apps you run. I have noticed that it spikes whenever gmail is doing the email sync or I am running videos from whatsapp etc.
So, don't worry about a larger value if you have been using the phone. The loadavg for idle phone should be close to 0, but it rarely is, because our phones are always doing something in background. The lowest I have seen it drop is 0.08, and then gmail brings it up whenever it does a sync. I have several accounts linked in gmail (yahoo, hotmail, google, work), so its understandable.
One thing you can do to monitor is to see which processes are eating up the CPU with:
Code:
ps | sort -n -k5 | tail -n 5
top -m 3 -s cpu -n 2 -d 2 | grep -v "^$" | tail -n 6
It will show 5 top memory consumers and 3 top CPU consumers. Put it in a shell script and run it periodically to collect some stats.
I have noticed dhd_dpc taking up CPU cycles. But I need the wifi... So, unless and until someone comes along and optimizes the kernel driver for wifi on M7, that's what we got! I don't think anybody would touch the driver code for m7. So, some things will never get fixed for m7.
On the other hand, the cycles eaten by system_ui and system_server are inexcusable! They can be fixed by CM/Google in non-device specific code. May be that will happen as CM13/Marshmallow matures.

Thanks for the info. I'll try to collect some stats on my device to see what is putting a strain on the battery so much. As for the system, it has always been that way ever since lollipop came. Nobody bothers to fix it, and I am beginning to think that maybe they didn't notice the numbers or the switch from 5.0 to 6.0 happened so fast they just went "meh, we'll leave it and maybe fix it later if we remember". I never understood why most of the ROM and kernel makers try to add more new stuff without even fixing and optimizing the things that are the core of the new optimizations and add-ons. It just makes no sense to try to push something new on a broken foundation to begin with. The M7 is a great phone even now, and I had it for 3 years now. Naturally, the battery is very old now and the moment i start using the screen it drops 20% in an hour or so, making me have at most 3 hours of screen time. But with background usage restriction I get by on a daily basis just barely. Fixing the system cycles would be heavenly for me, but alas, maybe it will never happen, sadly
