Hello guys,

Some of you guys will recognise me, I was trying to make progress on Sultan's 3.10 kernel on his topic. After a while I've wanted to do that from scratch, in new base, and now I can say it's done.

This kernel is the one all recent flagships' use. Also 3.10 kernels' support will end in Oct. 2017, while 3.4 ones will end in Apr. 2017.
In theory it should have better memory management, less battery consumption etc. It took me about 7-8 months to come to this point.

Currently everything works.

Extra features

* KCAL
* 6 new governors
* Touchscreen driver has been updated and optimized - also S2W added, you can find it in Kernel Aduitor
* Works with pelya's USB Keyboard app.
* New charger driver features:

They're placed in: /sys/devices/qpnp-charger-ed443000
You need to reach them from some terminal app or adb shell.

threea_charge

Making it 1 will activate experimental 2.5A charge. It's triggered if AICL mA is 2000(if you're not sure about AICL mA, simply disable AICL by below parameter), temperature is appropriate and screen is off.
Only use if you have 2.5A or above charger. Don't use QC's Quick Charge adapters.
Untested, but can't damage your phone.

disable_aicl

Making it 1 will disable AICL and charger driver will always try to take 2A from your AC/wall charger (there's no problem if you charger isn't 2A)
You need to replug adapter to see the effect.

max_aicl_rate

Max. charge current. (Not exactly if it's below 0 Celsius)
It should be one of those: 100,150,500,900,1200,1500,2000. Other values will be rounded. Values below then 100 and higher then 2000 won't be accepted.
Has no effect if AICL is disabled via above parameter.
If threea_charge is enabled and this parameter is 2000, max current will be 2.5A.
You need to replug adapter to see the effect.

fast_usb_charge Can also be found in Kernel Aduitor

Making it 1 will charge your phone through 900 mA if it's charging via USB port.
You need to replug adapter to see the effect.

charge_limit

It only accepts values between 0-100. Charger driver will cap charge percent to entered value. It's known that capping it to 50-60 percent increases battery life.
Making it 100 will revert the effect.

soft_aicl_vol

It must be between 4350 and 5000.
Default is OP2 value (4465 - but algorithm is different from LinOS and you shouldn't directly enter Sultan's or LinOS's value).
Don't change that if you don't know what it is.


Ramdisk changes
Last update: 17-02-2017


in fstab.bacon:
* F2FS filesystems must be mounted without noatime option.
* "/devices/platform/xhci-hcd" --> "/devices/*/xhci-hcd.0.auto/usb";
* "voldmanaged=usbdisk:auto" --> "voldmanaged=usb:auto";

in init.bacon.rc:
* qcom_oncrpc must be removed from loc_launcher (this is CM's mistake)
* netmgrd must also have system group
* qmuxd's user must be changed to root
in init.qcom.power.rc/init.recovery.bacon.rc:
* cpubw.40 must be changed to cpubw.47
These are only things different than CM ramdisk right now.

in anykernel patch format (all credits goes to @idprophecy)

Nobody knows is your warrant is still valid.
Also it's suspicious is there any warranty for OPO.

After you started to use this kernel, I'm not resposible for anything happened to your device.
* Encryption works but I cannot guarantee that it won't cause any data loss.
* They're all AnyKernel.

* There will be two types of build after 19/05, one with CM camera driver, one with CAF/Sultan camera driver.

A little nostalgia :p (It's too buggy, you have been warned)
26-08-2016: http://www.mediafire.com/file/6j5xw1j1lel1tra/260816kernel310.zip

Source code link is available bottom of this post.

Technical side

* It is based on LA.BF.2.1.2
* You can use both LA.BF and LA.BR prima, I'm using LA.BF one with some LA.BR commits.
* Tspp driver was causing bootloop, so i've disabled it. And I don't know is it used at all, it's disabled in apq8084 devices (like nexus 6) even.
* I'm compiling it with GCC 4.8. I've switched to Uber 6.0 after 09-01 build.
* KGSL drivers is pretty messed up after 30-08 build. It's my fault.
* And compiled DT is in in arch/arm/boot, it was different in 3.4 I think.

Pull requests are welcome.

You can use use/fork/develop this but you should give credit for 3.10 kernel on your releases.

Did you like my work?

I appreciate all the donations, it will keep me motivated, also I'm a student so it will help me in my life :)
Addendum: PayPal has been banned from my country, if PayPal denies your transaction and if you want to donate, I can give you my IBAN.

Credits
Sultan - this kernel would be impossible without his helps & his first 3.10 kernel attempt.
Ra1nst0rm - for helping me to upload repo - releasing this would be impossible due to creeping internet in here.
Mecca UL & idprophecy - for their insane effort to test and improve this kernel =)

My country is famous with creeping internet, so I gave a chance to github import tool to import it from caf first, but it has been almost 1 day and progress bar still seems full, I think it got stuck.

I will be grateful to anyone who gives me LA.BF.2.1.2_rb1.5 kernel imported repo :silly: Ofcourse I can do it myself but I don't know when I can.

And I will add credits to one who upload it.

Works beautifully with CM Nightly 15-05 on a secondary Multirom installation. GPS worked well for me, but during calls the other party couldnt hear my voice. So reluctantly removed for now. Hope you fix the issues and continue developing the kernel for our beloved OPO.

Yeah, GPS works well actually but it shouldn't be perfect since part of it crashes.

Thanks!
