kernels Dafna - post-Huexxx's expirience of diana_v.3 optimization

kernels work properly on both IZS & ICS
main features: swap & zram support, undervolting, wided frequencies' scale 200Mhz-1.1Ghz
swap usage is strongly not recommended, as it causes lags in UI, zetram, otherwise, is almost a musthave.
wonna announce in advance, that dafna_v4.* would be (soon, i hope) on the latest 3.9.4 stable linux sources.
dafna _v3.3:
haven't changed a byte in code - only trickstering with linaro's commandline parameters.
results could be seen by eye; according to tests dafna_v3.3 makes now on lionheart even larger figures than diana_0.3 did on performance.
necessary tunings (without them rom would lag or even become unstable/freezed): lionheart, bfq, cache 2Mb, aggressive OOM, seeder, zram.
sicdezmond (from 4pda.ru) suggests that it may be usefull before installing this version to wipe cache & dalvik.
dafna_v3.2:
v 3.1 + additional undervolting of 800 Mhz.
rebuilt on the latest versions - android-ndk-r8e & gcc 4.7, theoretical and/or practical achivements of this rebuilding had to be finded yet.
due to the widely known gcc 4.7 bug, wifi module does not compile properly (any help or ideas for any workaround would be greatly appreciated), but module from the previous version of dafna could be just copied to /etc/wifi (proper permissions 755 had to be checked/set, of course).
overall feeling: it's much quicker and has lower power consumption than dafna_3.1.
necessary tunings (without them rom would lag or even become unstable/freezed): lionheart, bfq, cache 2Mb, aggressive OOM, seeder, zram.
dafna_v3.1:
v3 + upper limit changed to undervolted 1.1 Ghz according to lgeob's (from 4pda.ru) idea of frequency's changeling.
necessary tunings (without them rom would lag or even become unstable/freezed): lionheart, bfq, cache 2Mb, aggressive OOM, seeder, zram.
dafna_v3:
v2 + tuned undervolting + changing of lowest frequency to 20Mhz (also added upper limit 1.1Ghz is recognized, but not used by the system).
necessary tunings (without them rom would lag or even become unstable/freezed): lionheart, bfq, cache 2Mb, aggressive OOM, seeder, zram.
Historical review:
dafna_v2:
v1+ undervolting of wifi + disabling ipv6 + disabling ethernet in company with a pair of not needed TCP protocols.
dafna_v1:
based on diana_v.3 by Huexxx, swap + zram, light undervolting after lgeob's ideas, disabling of most of the kernel's debugging.

Does this work on izs (4.0.4)?

thanks for showing a missing point in description, edited.
kernels were tested on izs 0.2, izs 0.4, ics 30b-f.

Will give a try...

It works on trasmusic ics rom too.
Btw how to set up those tunables?
I know about governors but dunno which app is compatible with the kernel.
Edit: nvm I just tried trickster mod and it works ok for now.

any app you like.
the simpliest and easiest way is to set it up with the init.d scripts (seeder, of course, had to be only installed).
as to the apps - android tuner, android trickster, no-frills CPU (for example) - most of them can tune partly required, but none can tune all mentioned.

Great job mate.I'll test it on Trasmusic v30f.Hope that oc is stable
Edit: Instable for me.Games are force closing and some apps too

No need to be so sarcastic.
And no, there is no direct link to github in your OP.
The only link present in your OP is a russian webpage, where there IS a link to github.
So I know, it was just two clicks to get the github link, but could you post it also in the xda thread OP? Its not such a hard task, isnt it? =)

i installed this kernal and can no longer get root. Are you having this problem. I am on kaspers Omni rom as well.

I had the same issue and had to re-flash the rom. Looking at the file, it looks to be for CM based rome only.

Most if not all modern aosp Roms like aokp, pacman, and others use the same kernel source. I am using a cm10.2 based rom on my tablet but, a kernel should not effect superuser. What errors are you getting? Have you tried updating Superuser or supersu which ever one is installed?

When I tried to run Titanium Backup, but it kept telling me that it did not have root.
I tried installing and updating each of the Superuser and SuperSU separately without success. When I re-flashed the PAC 4.3 rom, things went back to normal.

Flashed UPDATE-SuperSU-v1.80 will gain root again......

You will need Kernel Adiutor (free from the play store) or similar app capable of allowing you to switch I/O schedulers and
CPU governors in order to be able to change and set those.
I can recommend this.

Thanks for your work so far :good:

booting went well. However WiFi doesnt work for me :/ I uploaded the logcat-output filtered for "wifi" to hastebin. If you need anything else for debugging let me know. Thanks to dual boot I will keep your custom kernel on one ROM

Thanks for trying out the kernel. That's weird about the WiFi. I have never had that happen in the bunch of times I have flashed it. I will def look into it.I'll have a look at the log, although at this point I'm also not that great at interpreting those, so it may not help. I'll see what I can do though

OK,well after looking at the log and trying to decipher it and then thinking a bit I have only come up with one possibility.Maybe somehow your wpa_supplicant.conf file located in /data/misc/wifi/wpa_supplicant.conf has the wrong permissions for some reason.If you want you could try to check and possibly change the permissions.If you decide to try this I would backup the file because you never know.
The permissions should be: Owner - wifi Group - wifi...
Owner read and write/Group read and write/ others none.
If your permissions are correct on that file the only other thing I could possibly think of to do if you wanted would be to delete that file,wpa_supplicant.conf.Only after you back it up it though because you will lose all of your passwords,and reboot.It should recreate it.Do that at your own risk though.This is all I have come up with because I have never had that problem,so it's a bit difficult.

I am sorry, I think the error was my fault and not a bug of the kernel. I think the build that I am running at the moment is one I build myself and used sabermod toolchain. I remembered that I had the same problem using DMPKernel on that build. I thought I was using one of hennymmc's builds by now - so, sorry for reporting but thanks for looking into anyways.
Unfortunately I tried both and didnt solve the issue ,the permissions were set correctly btw.
I just installed the CM13 on another partition but - unless I have a flashable zip file - I can not install your kernel on that one. Would it be possible to provide the kernel as .zip?

I actually haven't touched this recently at all.I've been spending too much time on the mess that is my AOSP build [emoji2]
I give up on that for now though.It's giving me a headache.
I will try to get back to this soon,as I don't even think it works with any of my builds.I don't know.I'm not even using this right now.
I never actually had any real audio issues with this however and I did use if for awhile,so that's strange.

[KERNEL] ESAL v2 - Marshmallow

Hey, it's been a while since my last (and failed) release, so let's see if you can help me on this one.
As you might have guessed, I have compiled our latest kernel, and this is my own version!
Right now, people have reported battery life improvements, I'd love to hear what you think!
Changelog
Code:
V2.0
* Enabled some CPU governors.
V2.1
* Updated KSM with uKSM.
* Added Thunderplug hotplugging driver.
* Added PMC and Smartmax CPU governors.
* Added Init.d support. (Make sure the file has the proper permissions)
V2.2
* Updated GPU drivers to be compatible with EMUI 4.1.
* Added Intelliplug hotplugging driver.
* Improved GPU performance.
Downloads
V2.2 (New): https://github.com/XePeleato/ALE-L21_ESAL/releases/tag/v2.2
Instructions

Flash from recovery
Done!

Guide
I am going to try to help you to decide what settings you should apply
First of all, I recommend to install Kernel Adiutor.
If you prefer battery life:
Start Kernel Adiutor:
Go to CPU in the drop-down menu and set as governors PMC or Smartmax​Then go to CPU hotplug and don't enable many cores, since more online cores means more power used. You can also set the Endurance level to Quad-core​
If you prefer performance:
Start Kernel Adiutor:
Go to CPU in the drop-down menu and set as governors performance (will set the CPUs to their max frequency)/ondemand/interactive​Then go to CPU hotplug and make sure to lower the load threshold, having a low load threshold will make your phone use more cores (if you experience lag while playing, maybe it's set too low, so use a wise value, do your testing.)​
To conclude, I just mentioned where the settings are and some example values, if you love to play games you won't use the same settings as someone that just likes to read emails and use Google Chrome, find the settings you are comfortable with, and don't forget to set Apply on boot!
Now some screenshots of AnTuTu and 3DMark with Performance governor and Esalv2.1:

As you can see, even 3DMark detects that my score is higher than the average, try to beat that with stock kernel!
I hope you enjoy it, and please, I'd love to hear your suggestions!

just a quick question if you dont mind : any way to flash it via twrp ? so in case that something goes wrong i can easily restore the old one with a backup .

I'll upload a flashable zip, but it shouldn't be a problem, if you take a backup of your Boot partition and restore it, it will overwrite the kernel.

thanks! i will try it and see how it goes.

Sim gets detected but stucks at the point of unlocking it.

waiting for comments on the kernel

I kept the screen active and it worked after 40s
Basic stuff works , so god for daily usage I guess. Is rep on github up to date of this kernel because I compiled it myself and nothing worked. I either think my toolchain is the problem.

Also the governors do work , I don't know if all do but theres a noticeable performance change when chaging it. Over/Undercloking still doesnt work , but its not the kernels problem. The power genie of emui controls it.

Yes it is, the v2 branch, you'll need to edit build.sh to point it to your toolchain.

Thanks I compiled the "v1" branche....

Wi-Fi, Bluetooth, NFC works.
I will test mobile data, GPS tomorrow.
"Bug": SIM unlock takes a lot more time than stock kernel.
Great work! May I ask what features are you going to add into? OTG maybe?
Anyway: Great! Keep it up!
EDIT:
How can I change governor? I'm looking for extra governos (PMC, Smartmax) in Kernel Auditor but I can't find them

Hi, can you find ondemand, interactive, powersave...? OTG is enabled, the problem is at the rom.

Hi,
Yes, I can.
Thank you for the heads up about OTG, I didn't know that

I just tested it for herolte, RR, not the new tree. It successfully boots up, I will report if I find any other issue. Thanks for the kernel.

Wowowowowow another one for aosp roms, now with wakelocks and voltage control! Flashing aokp right now (no substratum issues) will report back on how it goes after a few cycles

Tested on RR build 07/18 and working fine.
But there is no option for led fading!
Good work?

Missing quite a few CPU governors

Installed on RR (7/29) and doesnt seem to boot.
Galaxy S7 G930F International variant.

It's because it doesn't run on new tree

Can you make run on the new tree ? Also is the smartmax the default governor?
Thanks for your work.

For now I cant., Because new tree isn't that stable. So I'll wait until new tree is stable. Smartmax isn't default governor.

Oh alright, hope things will work out soon, thank you for your efforts ??

Does enforcing mode work with this kernel? If not, are planning to implement it?

It was a short period of time but I can see the SOT is fine with normal usage (streaming, gaming, browsing). I just dont know why aosp kernels on s7/edge hate facebook app so much that the big cluster maxes out its frequency, resulting in an overheating and massive drain when using fb app and would require a reboot to get it back to lower frequencies.
A few more optimizations then this would be a better kernel than the ones included in rom.zips
