Hi, I modifed stock 23.5.A.1.291 kernel to support f2fs file system etc.
The kernel is EXPERIMENTAL so I need testers.
Features for now:
F2FS support (without encryption)
Disabled sony RIC
SELinux permissive
GPU overclock
Kcal support
IntelliThermal
init.d support
Multirom works using no-kexec workaround (WIP kexec-hardboot)
DIRTY COW exploit patched!
Both f2fs and ext4 partitions support
Custom CPU govenors
Custom ZEN I/O scheduler as requested
Adreno Idler
Intelli-plug
Voltage Control
Features that will be added:
CPU overclock
Optimizations
working kexec-hardboot patch
CPU govenors
I/O schedulers
you tell me?
Features that will not be added:
TWRP - install it with fastboot (custom roms also have them )
Prerequisites:
Official TWRP from https://twrp.me/ (it contains mandatory mkfs.f2fs file)
Xperia Z3 Compact
Fastboot drivers installed and unlocked bootloader
FizTech kernel - helium
Instructions:
I recommend to do this after fresh install of ROM of choice. I tested my kernel on SLiMM and AOXP.
Kernel must be flashed through recovery. The zip contain wifi module and script that corrects partition layout.
If you want to use f2fs filesystem then follow optional steps which will format your /data and /cache partitions. (Maybe backup? )
Think thrice if you are determined to install this!
Install official TWRP
Code:
fastboot flash recovery twrp.img
To enter recovery press POWER and VOLUME down buttons simultaneously when phone is switched off. It should boot to recovery. This requires new bootloader, that allows booting to recovery.
Install ROM of your choice
F2FS optional : Wipe->advanced wipe select /cache and change filesystem to F2FS (Repair or Change File System)
F2FS optional : Do the same for /data
Install kernel ZIP
Reboot and wait. Sometimes it takes few minutes, especially after fresh install.
F2FS advice: If device is not booting, please reboot to recovery. Check your if your /data and /cache filesystems are F2FS. If not then repeat F2FS optional steps. Even if your partitions were F2FS, install kernel zip once again.
Optional: install TWRP once again if it was damaged by ROM installation.
If you don't see F2FS format option in "Repair or Change File System" then your recovery doesn't have mkfs.f2fs file in /sbin of your recovery (it needs to have permissions also). Use offical TWRP from @someone755

If you wanted to reserve this one, though luck
Not often I get tagged in new kernel threads. All the best man, and happy holidays

---

A day were a new kernel project is starting is a good day...
Good work up to now...
Maybe UV would also be nice...

---

Good to hear about the new kernel. Awesome works!
I'm having with issue with the touch screen on my Z3 compact. The top and bottom of screen is unresponsive. But it happens on main screen, not in lock screen, not in welcome screen (when installed a fresh rom), and also not in TWRP.
I believe this related to the Sony' kernel. Could you help to investigate and hopefully fix the issue.
I will test the rom if hearing any word from you
Many thanks.

Did I understood correctly, that you installed my kernel and such issue appeared? If yes: does the it exist on other kernels? I didn't modify anything in panel/screen/touchscreen. The only possible problem for now is that some kernel modules are not loaded. I must check which one is resonsible for what to decide whether to enable it or not or if it could be responsible for such issue (which I doubt).
What about your charger? In some cases broken chargers caused misbehaviour in touchscreen . For instance they are not properly grounded.
I need more information to help you.
Regards

Can someone please explain to me what are benefits of f2fs, and what does it mean? Are there any bad sides of using it?

If you search on Google, you will find that f2fs is a filesystem developed by Samsung, faster than the others file systems(if used on emmc, SD card and ufs) so it'good if we could use it. But the kernel must have compatibility for it. Correct me if I'm wrong! And I'm looking forward using this kernel!

It's not from your kernel. It's issue on Sony's ROM, which causes top and bottom screen area is not touchable. I think it was the kernel issue. Some forks from the thread had the same of my issue: http://forum.xda-developers.com/z3-compact/help/home-button-t3151587
Many appreciates if you can figure out and have some fixes included in the kernel.
Thanks,

Cool! All the best developing this kernel. I will surely try this. BTW, do you see and performance and battery improvements in SliMM or AOXP?

Yes, both have better performance and battery life than stock.
PS. Version 2 released - codename Helium

Cool I'm developing AOXP... And 1.3 I will be releasing 1.3 now!
Also, how stable is the kernel?

This kernel Is awesome! It would be good if you added zen io, Adreno idler and dynamic fsync

Can you make version for concept?

Maybe I will consider it in the future. Now I would like to focus on stock based kernel and patching it.

I have a problem with my sd 64GB with this kernel i get a notification that says "corrupted sd card" i touch to format and fix but not work and my sd work with twrp :/ i use SLIMM 3.8

---

noob question could you tell me a good setup for running games without lag? I have problems in games like NFS no limits and RR3 in stock.
I tested another kernel only that always hangs up then I need to reboot.
Game always starts well only after a while drops to 15/20fps I'm almost changing smartphone. I've seen that is some limit that sony puts after a certain temperature thank you for help

Hi, what is the filesystem of your sdcard?
Have you tried to format in TWRP or with help of PC?

Hi, after certain temperature a feature called CPU throttling is enabled. It's implemented by thermal driver to prevent damage to your phone. I haven't tried it in gaming but I read many positive opinions about intelli thermal driver which is included in my kernel.
I'll install that game and tell you how it works for me.

Hi, I use exfat, if I already try to format it in twrp but it does not work with the rom, in the pc it works, in twrp also and with another kernel also it works, it is kind of strange maybe it has something to do with format extfat
